Portable Power Primer: A beginner’s guide to selecting the best battery option for your field radio kit

July 18, 2021 Thomas Witherspoon 13 Comments

The following article originally appeared in the April 2021 issue of The Spectrum Monitor magazine:

I’ll admit it: I’m a massive fan of field radio.

In 2020, I easily spent a total of 100 hours outdoors with my radios activating a total of 82 sites for the Parks On The Air (POTA) program alone. This doesn’t include hours and hours of SWLing (shortwave radio listening). It’s been great.

Taking radios into the field is so much easier to do today than it was in, say, 1985 or earlier, because we have so many more options for powering our gear in the field. Not only have radios become more efficient in operating off of battery power, but we now have so many affordable and lightweight rechargeable battery choices on the market.

In the following article, let’s take a look at some portable battery power options for your radio gear. By “portable,” I’m talking power options for those of us who load a backpack or carry case and head to the field.

To keep the scope of this article in check, I’m also going to focus only on rechargeable battery options. And rather than get bogged down in the nuances of battery chemistries, we’ll focus on the end result––the pros and cons of each battery type, and how practical they might be for your field application.

In addition, I’ll also limit discussion to batteries that can be purchased of-the-shelf rather than addressing homebrew options. While I love building things, I’m very cautious when dealing with battery charging because if not done correctly, the results can be dangerous. I prefer obtaining products from trusted suppliers who thoroughly engineer and test their equipment.

Let’s take a look at several types of batteries, and speak to their advantages…as well as disadvantages. Then––as we summarize our findings––let’s discuss how to choose the right option for your needs.

Consumer-grade rechargeable batteries

Let’s begin by talking about the lowest-hanging fruit in terms of portable power: everyday rechargeables in the form of 9V, AA, AAA, C, and D cells.

While, admittedly, these batteries are not typically an option because of their limited capacity and energy density, they can still be a very practical power source for portable receivers and even a few QRP transceivers.

Rechargeable battery chemistries have improved with time, thus I no longer purchase nickel-cadmium (Ni-Cd or NiCad) or legacy nickel metal hydride (NiMH or Ni–MH) batteries.

These days I almost exclusively purchase low-self-discharge nickel metal hydride (LSD NiMH) batteries, specifically, Panasonic Eneloop batteries (Amazon affiliate link). Although they’re a pricey option compared with generic NiMH batteries, and might even be overkill for certain applications, I do love the shelf life of Eneloops.

Of course, the benefit here is Eneloops have that low self-discharge. They will maintain charge better at rest (i.e., when not in use) than legacy NiMH or NiCad batteries. From my real-word usage, I’m convinced that Eneloops also demonstrate better longevity over numerous charge/discharge cycles than many others.

All of my portable shortwave receivers that accept AA or AAA batteries are powered by Eneloops exclusively.

And although I’ve never done this myself, it is also possible to power highly-efficient QRP transceivers with Eneloop batteries, so long as you use a multiple battery holder to increase voltage and capacity to match both your rig and your desired amount of operating time.

Keep in mind, though, that most transceivers will require a block of at least ten AA batteries to reach a voltage around 12 VDC. As you might imagine, it can be cumbersome after using your radio in the field to remove all ten of these batteries and charge them in a charger that can only hold, say, four batteries at a time. I personally prefer other options, but this one is certainly a fairly affordable, safe, and accessible option.

Note that in recent years, Panasonic started offering Eneloop Pros: while pricier than standard Eneloop batteries, they offer slightly higher capacity at the expense of overall longevity (roughly 500 versus 2100 total charge/discharge cycles). Since the voltage is the same, I’ve never felt the need to use higher-capacity Eneloop Pros.

Rechargeable Panasonic Eneloop AA batteries (non-Pro version):

Price: $2.25 – $4 US per battery, depending on the number in the package
Weight: 4 grams/.4 ounces per cell
Voltage: 1.2 V each
Longevity: Excellent, up to 2100 charge/discharge cycles
Ease of recharging: Simple via Eneloop OEM chargers
Solar- charging option: Eneloop originally marketed solar chargers, but doesn’t seem to do so presently

Sealed Lead Acid (SLA) Batteries

When I first became a licensed ham radio operator in the late 1990s, sealed lead acid batteries were the primary battery power source used for field radio operation.

At the time, these batteries were one of the best options for portable radio use because they could be purchased in a variety of sizes (based on amp hour capacity), and unlike flooded lead acid batteries, they required no maintenance––and being sealed, did not outgas.

While I’ve owned everything from 3 Ah to 15 Ah SLA batteries, I found the once-ubiquitous 7-8 Ah size to be the “sweet spot” in terms of portability and capacity.

SLA batteries are still among the most accessible high-capacity batteries on the planet. No matter where you travel, it’s likely you’ll be able to hunt them down in any hardware or electronics store. Our small local hardware store has a wide selection of these at their battery kiosk.

What are some of the pros of these batteries? In terms of “bang for buck,” the SLA is still hard to beat. You can purchase a quality 7.2 Ah 12-volt SLA battery for about $18-20 US (affiliate link). This would be more than enough battery to power a typical QRP transceiver for many hours on end. Chargers are also inexpensive––you can purchase a dedicated charger for about $10-15 US. Not bad.

In addition, 12-volt batteries are nearly ideal for amateur radio use since most transceivers are designed to operate with 12-13.8 volts DC +/- a modest margin.

There are some negatives compared with more modern battery chemistries, however. For one, SLA batteries are much heavier than the batteries we’ll discuss in the following sections. After all, they’re (still) made of lead! In addition, the battery’s longevity will be negatively impacted if you discharge it too deeply.

With that said, if you take care of an SLA battery, it can give you five or more years of service life in the field, yielding an excellent value for the modest investment. If you have an application that requires relatively little capacity from the battery, you might get a very long service life, indeed. In 2011, I built a remote antenna tuner box around an LDG Z11 Pro ATU and a discarded 7Ah 12V SLA battery. At the time, this battery could no longer hold voltage long enough to be reliable in the field, but I knew the Z11 Pro requires very little in the way of power, so I thought I’d try it as a power source anyway. Since the remote ATU box isn’t near an outlet, I charge the SLA battery with a 5-watt solar panel I purchased used at a hamfest with a Micro M+ charge controller. A decade has now passed, and that SLA battery continues to power the Z11 Pro even through seasonal temperature variances of -10F/-23C to 90F/32C. Not bad! Again, keep in mind this application works because the Z11 Pro is so flexible in terms of power requirements––it’ll operate on 6-16 volts DC at 300 mA with a 20 uA standby current.

Clearly, SLA batteries are affordable candidates for back-up power in the shack during occasional power outages.

Price: Most affordable option per Ah of the batteries listed here
Weight: By far, the heaviest of all the battery options in this article
Voltage: Various, but 12VDC is very common
Longevity: Very good if properly maintained
Ease of recharging: Easy, via simple charge controllers
Solar charging option: Multiple types of charge controllers can be used with SLA batteries; among the listed batteries, the easiest and least expensive to charge via solar

Lithium-Ion (Li-ion)

Without a doubt, lithium-ion batteries have revolutionized the consumer electronics world.

Why are they so popular?

First of all, their construction allows for a variety of form factors ranging from cylindrical cells to slim packs and pouches so thin they can fit in an ultra-thin mobile phone, eReader, or tablet. They’re the easiest type of battery to accommodate in compact consumer electronics, and indeed, they power most of the consumer electronics we’ve put to use in the last decade.

Secondly, they have a very high energy density, thus pack a lot of capacity for the size and weight. Indeed, if size and weight are your primary requirements, li-ion batteries should be high on your list.

In addition, Li-ion batteries are ubiquitous and affordable because they’re used in so very many applications.

There are negatives, though, with these power sources. First and foremost, they’re very sensitive to over-voltage and over-current events that initiate a thermal runaway. To prove this point, I’ll share some first-hand experience from the early days of large lithium-ion packs…

Li-ion Horror Story

In 2011, I evaluated a lithium-ion battery pack with integrated 5V USB chargers and even a simple one-outlet inverter from one of the big names in portable power systems. At the time, this was a new battery pack and a relatively new technology, at least in terms of the energy density and compact size. After receiving the battery, I charged and discharged it perhaps twice during testing. I had a flight scheduled from North Carolina to California, and decided I’d take it in my carry-on bag to power my laptop in flight. It worked fine on the flight to KSFO. Once there, I recharged it. On my return flight, it simply didn’t work. I thought perhaps I hadn’t plugged it in properly, or that the hotel outlet I used didn’t work. Upon arrival I emptied my travel pack onto the bed and plugged in the battery pack; it indicated it was taking a charge.

After doing a few projects around the house, I went back up to the bedroom and was greeted with an overpowering smell––almost like the pungent chemical odor of nail polish remover. I looked everywhere for the source of the odd smell. Finally, I located it: it seemed to be coming from the battery pack. Upon examination, I could tell the battery had begun to swell. As I lifted it up, I noticed that the bottom portion was essentially in a state of melting. As quickly as I could, I unplugged it and removed it from the room. I then discovered that in the thermal runaway process, it had begun burning through the sheets and mattress of the bed. Shocked, I suddenly realized it could have burned down my home.

Keep in mind, I was completely new to this battery technology, and this was years before thermal runaways made the news and airlines began restricting their transport. To my relief, the company from which I purchased the pack ended up pulling that model off the market, and even reimbursed me for the mattress and bedding. But it was a hard lesson learned.

If I’m being perfectly honest, this lesson had a major impact on my willingness to experiment with Li-ion battery packs.

The problem with the model of pack I had purchased was not the battery chemistry or construction, per se, but the charge controller). The fact is, Li-ion batteries require millivolt accuracy and a number of protections to detect and stop thermal runaway. Battery packs with multiple cells need a battery management system (BMS) that also balances the cells and monitors them closely. Fortunately, most manufacturers of the technology now understand this.

Modern Li-ion cells and chargers are much safer and more stable

Since then, Li-ion battery chargers have become both orders of magnitude safer and more effective. Still, I only charge these batteries on a surface which, should the battery be tempted to melt down, would be less likely to be damaged or serve as a fire hazard. I also never leave them unattended during charging.

With that said, I don’t think Li-ion batteries are to be feared. Obviously, many of us walk around with one tucked in our pocket all day––in our smartphones! They’re generally considered very safe now. Of course, I’d only buy the best and would steer away from the lowest-costs units you might find on eBay and Aliexpress, as many of these products are made in places with little oversight or regulation.

Another interesting fact about Li-ion battery packs is that since their voltages are usually available in multiples of approximately 3.6 volts (e.g., 3.6, 7.2, 10.8, 14.4 and 18 volts), they are not always ideally suited for radios that require 13.8V input power. Some packs, however, have circuitry that provides an output voltage closer to your desired amount.

One Lithium-ion battery pack I’ve been using with my Mountain Topper MTR-3B, Elecraft KX2 and KX3 transceivers is a (very affordable) TalentCell rechargeable 3000 mAh Li-ion battery pack that provides both 12V and 5V USB power. It has built-in charging circuitry and is very compact. I purchased mine for about $25 on Amazon.com, and have been very pleased with it so far.

Summits On The Air operators often place priority on smaller-sized and lighter-weight power sources, and thus turn to Li-ion battery packs. Many SOTA friends have invested in high-quality balance charger/dischargers to maximize the life of their batteries, and have been happy with the performance they receive. A quality charger may costs upwards of $60, but is worth the investment if you choose Li-ion batteries as your portable power of choice.

Price: From affordable to pricey, depending on capacity and charger investment
Weight: The lightest weight portable battery options in this list
Voltage: Often in multiples of approximately 3.6 volts: (3.6, 7.2, 10.8, 14.4 and 18VDC)
Longevity: Good. Typically around 400-500 charge cycles if properly maintained
Ease of recharging: Simple, if a self-contained pack; more complex, if using multiple cells that need balancing
Solar charging option: Not advised (yet). There are a number of homebrew Li-ion solar charging projects on the web, but I believe this battery chemistry fares better with a balance charger connected to a stable AC power supply.

Lithium Iron Phosphate (LiFePo4/LFP)

I typically use my 15 Ah LiFePo4 battery pack when powering transceivers like the Mission RGO One that can push 55 watts of output power. I also use this battery to power my Elecraft KXPA100 amplifier on Field Day.

The final type of battery chemistry we’ll cover here is my favorite of the bunch.

There are good reasons why Lithium Iron Phosphate batteries have become one of the choice rechargeable batteries for field radio use.

LiFePo batteries are inherently stable and safe
They offer a longer cycle life than that of other Li-ion, NiMH, NiCad, or Lead Acid batteries–thousands of charge cycles as opposed to hundreds
LiFePO batteries have an excellent constant discharge voltage
LiFePo batteries use phosphates––as opposed to cobalt or nickel, which are supply-constrained and carry heavier environmental concerns
LiFePo batteries have a lower self-discharge
LiFePo batteries are very lightweight compared to SLA batteries
3.2 V nominal output voltage means that four cells can be placed in series for a nominal voltage of 12.8 V, near ideal for most field radio gear

Any cons? Yes…while they’re lightweight, LiFePo4 batteries aren’t as compact as Li-ion battery packs. But the primary negative here is the price. At time of print, LiFePo4 batteries have the highest cost per Amp hour of the batteries discussed in this article. With that said, due to the excellent longevity of these batteries, the LiFePo may be the most cost effective option in the long term.

LiFePo4 battery systems sport built-in battery protection modules to address concerns like over-voltage and balancing.

How do LiFePo batteries stack up?

Price: One of the pricier options, when you include the battery and charger
Weight: Very light weight, but size tends to be larger than comparable Li-ion packs
Voltage: Excellent match for gear requiring 12V – 13.8 VDC
Longevity: Excellent. Thousands of charge/discharge cycles
Ease of recharging: Simple, using the provided charger (battery packs have a built-in charge controller)
Solar charging option: Bioenno sells charge controllers designed to work with LiFePo batteries, handy for the field

Without a doubt, the best-known LiFePo battery manufacturer in the world of ham radio is Bioenno Power. I’ve purchased their batteries exclusively and have been incredibly pleased with the quality, longevity, and performance of their products.

Choosing the right battery for you

Each one of these battery types have their pros and cons, and you can find lengthy, in-depth discussions online about the nuances of each battery chemistry. At the end of the day, however, what matters is which one best suits your particular application and provides your gear with the appropriate amount of voltage.

Here’s when I would reach for each of our types of batteries…

NiMH LSD AA batteries

If you’re willing to use a battery pack to run 8-12 cells in series to achieve your required nominal output voltage, Eneloop batteries are relatively affordable, lightweight, and of course, power an array of electronic devices in our world.

If you plan to use QRP power for short periods of time, these may suit your needs quite well. My buddy and Elmer, Eric (WD8RIF), has used Eneloop batteries to power his Elecraft KX3 for the majority of his Parks On The Air activations.

Of course, AA Eneloop batteries are also invaluable for those of us who have an arsenal of portable shortwave radios that accept AA cells!

Sealed Lead Acid Batteries

If you’re on a very tight budget and weight is less of a concern, SLA batteries are a great choice. They’re an especially affordable option if you plan to make a solar-powered battery pack since charge controllers are quite simple and affordable.

If you’re looking for a stationary back-up battery for home, these are an excellent choice, as long as you keep the charge topped up.

Li-ion Batteries

Backpacking or flying overseas, and size and weight really do matter? Purchase a Li-ion battery system. Li-ion cells and packs offer the highest energy density of any of the battery chemistries in this list. They’re incredibly compact––and as long as you use a quality charge controller with built-in protections, and you don’t damage or puncture an actual Li-ion pack––they should be quite safe, and you’ll be pleased with performance. Note: Keep in mind some airlines have regulations about the size of Li-ion battery pack you’ll be allowed to carry on board, so do check before departure.

LiFePo Batteries

The 9V 3Ah Bioenno LiFEPo4 pack is very compact and pairs beautifully with the Mountain Topper MTR-3B as this particular transceiver prefers voltages at 12 volts and below.

If you’re looking for a simple, effective portable battery solution that is almost custom-designed to power radio gear, invest in a LiFePo4 battery and charger. I have everything from a 15 Ah 12V LiFePo4 battery that can power my 50 watt Mission RGO One transceiver, to a 3 Ah 12V pack I now use for 2-3 hours in the field at a time with my QRP transceivers. Bioenno has recently sent me a 9 V 3 Ah battery pack to test with my Mountain Topper MTR-3B––it’s incredibly compact, since it only needs three 3.2V cells in series. LiFePo batteries are also the ones I suggest for those who are new to the world of battery packs and want something that is hassle-free and simply performs.

I admit, I’m being transparent here about why I own a total of three LiFePo4 batteries from Bioenno Energy––they’re amazing and I know I can rely on them.

In summary…

…I would offer this final piece of battery-usage advice: whatever you do, don’t “cheap out” on your battery and charging system. No matter what chemistry you decide to purchase, buy the best quality you can afford. If using any variant of a Li-ion battery, heed my tale, and be sure any separate charge controllers you employ will protect your battery (and your home)!

And now…Go out there and have fun. I assure you: when you take your radios––whether portable shortwave radios or ham radio transceivers––to the field, you’ll find you can escape all of the noises that so often plague us indoors. And out there, you, too, may find your radio bliss.

Activating Anderson Mountain: My first drive-up one point summit

July 15, 2021 Thomas Witherspoon 2 Comments

As AA6XA wrote on his blog:

To quote the W4C association manager Pat, KI4SVM, “Anderson is a drive-up with no other redeeming qualities.” This perfectly describes the mountain. It is easy to get to, at the top of Tower Road, right off of Route 16. The road to the top get a bit rough in places, but is passable in any car.

He had me at “no other redeeming qualities”–!

I must admit that all of the summits I’ve activated so far have been pretty amazing: offering up spectacular views, wildlife, and wonderful hiking opportunities. All of them were also on protected public lands like state/national/county parks.

Anderson Mountain (W4C/WP-012)

Earlier this year, I made a spreadsheet of summits I planned to activate. Anderson Mountain was one of them because of its convenient location in my travels to visit family each week. I had also been saving it for the day that I planned to activate a nearby park–Tuesday, July 6, 2021 was that day!

Earlier, I had an amazing activation at Mountain Island Educational State Forest using the Yaesu FT-817ND, T1, and my speaker wire antenna. I completed Mountain Island in enough time I could also pop by Anderson Mountain for a quick activation. It was literally a six minute detour from my route, if that.

The mountain is directly off of US 16–the main highway between Newton/Conover and Charlotte.

You turn off of the highway onto a dead end road that leads to the summit. About halfway up, it turns into a single lane privately-maintained road that, as AA6XA noted above, is rough but passable in any car (well, save a Lamborghini but I’m guessing most SOTA ops don’t own one of those!).

The road to the summit is a straight–there’re no confusing forks in the road and it’s impossible to get lost.

Once on top, you’re greeted by a few clusters of communications towers. This is actually pretty common sight with smaller one point summits because they typically have superb line-of-sight to populated areas and are easily accessible by vehicle.

When you look around, you can understand why Pat would say it has no redeeming qualities: towers, rusty transmitter buildings, razor wire on chain link fences, and litter all over the place.

Not the sort of spot that would inspire Ansel Adams.

Judgement call

It’s worth noting here that, unlike POTA, you’re not allowed to operate from a vehicle during a SOTA activation–even at a “drive-up” summit. There’s no such thing as a mobile SOTA activation.

Indeed, you’re not supposed to operate in “the vicinity” of your vehicle either (although, there’s no distance noted and I’m guessing this is on purpose to allow leeway and the op to make a judgement call).

I set up in a little island of trees in the middle of a road loop on the summit. While I wouldn’t call it a hike, I did walk the entire summit after arriving to check for other operating spots, but decided to set up near where I parked the car. In fact, it’s really the only safe spot I noted in the activation zone to park since the road is single lane and you would otherwise block access to one of the transmitter sites. I thought about parking further down the road next to one of the transmitter fences, but I felt like that would have been on private property.

Side note: SOTA forbids operators from trespassing on private property without the owner’s permission. I checked the road very carefully for “no trespassing” signs, but the only ones I found were to keep people out of and away from the fenced-in transmitter sites.

I also thought about trying to operate in a spot on that little island where I couldn’t see my car as easily in the cluster of trees–to remove myself from the “vicinity” of the car–but that would have been awkward, too and only separated me an additional 10-15 meters or so. I chose the option where others could see me and I could see them if, for example, a Duke Energy service vehicle approached.

I was fully outside of my car, though, and not using it to support my antenna or any equipment–another important factor.

Sometimes as an operator you have to make a judgement call when you arrive at a site to stay within the rules and the spirit of the program. I’ve never had a SOTA or POTA activation where I felt I was splitting hairs until this one. I decided that this was the best scenario to activate Anderson Mountain in a way that wouldn’t inconvenience other property owners, nor cause suspicion that might lead to a future no trespassing sign on the road. It was the safest set up and I’m willing to bet most previous activators did exactly the same thing. I felt it was within the spirit of the program.

Now where was I–? Oh yes…

Gear:

Elecraft KX2
28.5 foot speaker wire antenna using one BNC Binding Post Adapter (affiliate link)
GoRuck GR1 USA

On The Air

Since I used the speaker wire antenna at Mountain Island, I used it on Anderson Mountain as well. I deployed the entire station within 5 minutes max: herein lies the advantage of using an arborist throw line, a shack-in-a-box transceiver like the KX2, and a simple wire antenna.

I first hopped on 20 meters CW, spotted myself to the SOTA network (mobile phone reception was superb, by the way) and started calling CQ SOTA.

Within three minutes I logged K6YK, KT5X, W5GDW, and K0LAF which already validated this SOTA activation.

Wow–validating this activation was, as my daughters used to say, “easy peasy lemon squeezy.” 🙂

I added WB6POT and N0RZ for a total of six stations on 20 meters within five minutes.

I then moved to 40 meters SSB and worked K8RAT, W4NA, and WN4AT all within about three minutes.

Finally, I moved up to the 17 meter band and worked F4WBN (our well-known French SOTA chaser) and K2LT.

Packing up my gear was as quick as setting it up.

Video

I did make one of my real-time, real-life videos of the entire Anderson Mountain activation with no edits. If you need a cure for insomnia, I encourage you to watch or listen to it:

At least one redeeming quality…

I mention in the video that some readers and subscribers have confessed that they feel SOTA is less accessible to them than POTA or WWFF. I would have to agree that summit activations are much less accessible than park activations.

For one thing, there are flat regions on our planet that lack prominences that qualify for the SOTA program. If you live in the middle of a prairie state, you may have to drive a great distance to reach the closest qualifying summit (although you might have a number of POTA and WWFF parks nearby).

In addition, summit activating generally involves hiking–which is actually the motivating factor for many of us (certainly for me as I love hiking).

Some would-be SOTA activators have mobility issues, however, and simply can’t hike great distances with gear on their backs.

This is where “drive-up” summits like Anderson Mountain come in: they’re much more accessible for those with health considerations.

If you live in an area with SOTA summits, but haven’t attempted an activation because you can’t do strenuous hikes, connect with local SOTA activators and ask for a list of “drive-up” summits. There are many of these around–some, like Anderson, are accessible because there are radio towers on top, other are accessible because they’re on a park with accessible vistas, or some are even in a mountaintop neighborhood.

An amazing SOTA activation on Mount Pisgah (W4C/CM-011)

June 18, 2021 Thomas Witherspoon 2 Comments

Here in the Asheville, NC area, there’s one mountain that almost anyone can recognize by sight: Mount Pisgah.

Mount Pisgah is prominent because not only is it one of the taller summits bordering the Asheville basin, but it’s also home to the WLOS TV tower and and a cluster of public service and amateur radio repeaters.

I’ve been eager to activate Mount Pisgah for Summits On The Air (SOTA). Along with Bearwallow Mountain, and Mount Mitchell, it’s one of the most popular SOTA summits in the Asheville area.

One reason for its popularity is because it’s so accessible. Not only is there a dedicated, large parking area at the main trailhead off of the Blue Ridge Parkway, but it’s also an easy hike from the excellent Pisgah Inn, restaurant, and camp grounds.

Being so accessible from the BRP, the Mount Pisgah trail also receives a heavy amount of foot traffic. Being locals, our family tends to skip this trail when we’re venturing along the BRP because it can be so congested at times.

Mount Pisgah (W4C/CM-011)

On Tuesday, June 1, 2021, Hazel and I decided to hit Mount Pisgah fairly early and avoid the crowds.

We arrived at the trailhead around 8:15 AM and there were very few cars there–a good sign indeed!

Hazel was chomping at the bit to start our hike!

The trail is only about 1.5 miles with a 700 foot elevation gain, so not strenuous.

It was blissfully quiet and we only passed two other groups of hikers on the way up.

I’ll admit that I was keeping an eye out for black bears, though. We saw bears very close to the trailhead entrance on the BRP that morning. I may have mentioned before that black bears are not something to be feared here in western North Carolina; they typically avoid people and your chances of being fatally injured by a black bear are incredibly slim–right there with being struck by lightening.Still, the black bears that wonder near populated spots like Pisgah along the parkway are often fed by tourists and lose their fear of humans. Not only that, but they even expect people to be food dispensers. Not good. As we say around here, “a fed bear is a dead bear” because feeding bears leads to aggressive behavior and the poor creature’s eventual euthanization.

But I digress!

Hazel and I reached the summit and were happy to find that we were alone. Pisgah’s summit can get very crowded as there really isn’t a lot of space–only a large viewing platform next to the massive tower.

When we arrived on site, the summit was surrounded in clouds.

I briefly considered operating from the viewing platform, but knew I would have to cope with a lot of curious hikers while trying to operate CW. Since I’m not a good multitasker, I decided to do what many SOTA activators do: carefully pass under the tower and find an activation spot on the other side of the summit.

Hazel and I found a small overgrown trail used primarily by those working on the tower. I deployed my station in a small clearing.

Gear:

Elecraft KX2
Chameleon CHA MPAS Lite
Elecraft AX1 (I brought this along as a spare in case I decided to activate on the viewing platform, but didn’t need it)
GoRuck GR1 USA
Rite In The Rain Weatherproof Cover/Pouch (affiliate link)
Jovitec 2.0 mm Mechanical Pencil (affiliate link)
Muji A6 Notepad (affiliate link)

For this activation, I chose my Elecraft KX2 and paired it with the Chameleon CHA MPAS Lite which has quickly become one of my favorite SOTA antennas.

I deployed the CHA MPAS Lite perhaps 15 feet away from my operating spot, in the middle of a spur trail. I was able to extend the 17′ vertical without touching any branches. I rolled out about 20-25′ of counterpoise wire along the ground.

After setting up, it dawned on me that I’d forgotten my clipboard. No worries, though! I simply flipped over my GoRuck GR1 pack and used the back as an operating surface.

On The Air

Not only was this a summit activation, but also a park activation–indeed, a two-fer park activation at that! The summit of Mount Pisgah is in both Pisgah National Forest (K-4510) and Pisgah State Game Land (K-6937).

If I’m being honest here–since I’m not a “numbers guy” and don’t follow my activation counts closely each year–it’s very tempting not to announce or count this activation in both the SOTA and POTA programs since K-4510 and K-6937 aren’t rare entities. The main reason for this is because, back home, I end up doing double entry with my logs: loading them via the SOTA online log submission tool, then entering them in N3FJP or TQSL for submission to the POTA and WWFF programs. It can be very time-consuming doing this.

I am working on a way to “massage” the ADIF file data so that I can submit it to both programs with less effort.

But, of course, I announced the activation on both SOTAwatch and the POTA site. At the end of the day, I’ve never *not* announced a dual SOTA and POTA activation because I can’t help but think it might offer up the sites to a new POTA hunter. It’s worth the extra log entry later.

Another plus with activating a site in two programs is that you’ll likely be spotted in both thus increasing your odds of logging the necessary contacts to validate your activations.

Turns out, snagging valid activations that Tuesday morning was incredibly easy. And fun!

Fabulous conditions!

I started on 20 meters CW and logged fifteen stations in eighteen minutes. The band was energized because not only did I easily work stations from France, Slovenia, and Spain in Europe, but also stations all over North America from the west coast to as close as the Ohio valley and into Canada.

I wanted to play a little SSB, so I moved to the phone portion of 20 meters and spotted myself on the SOTA network. I worked five stations in eight minutes. Fun!

Next, I moved up to the 17 meter band and stayed in SSB mode. I worked five more stations in nine minutes. Had I only activated this site in SSB on 20 and 17 meters, I could have obtained both a valid SOTA and POTA activation in 17 minutes.

Even though I knew I needed to pack up soon, I decided to hit the CW portion of 17 meters before signing off. I started calling CQ and was rewarded with sixteen additional stations in eighteen minutes.

Phenomenal!

All in all, I logged 41 stations.

Here’s the QSO Map of my my contacts–green polylines are CW contacts, red are SSB (click to enlarge):

A welcome interruption!

If you watch my activation video, you’ll note that as I moved to the 17 meter band and started calling CQ, another hiker popped in and introduced himself.

Turns out it was Steve (WD4CFN).

As Steve was setting up his own SOTA activation on Mount Pisgah next to the observation deck, his wife, Patty, heard my voice off in the distance giving a signal report.

Steve and I had a quick chat and coordinated frequencies so we wouldn’t be on the same band at the same time and interfere with each other.

After finishing my activation, I stopped by the observation deck and spent some time with Steve and Patty as Steve finished his SOTA activation and packed up his gear.

Steve was also using an Elecraft KX2 and strapped his telescoping fiber glass mast to the side of the observation deck to support a wire antenna. Very effective!

Hazel and I hiked back to the trailhead with Steve and Patty. It was so much fun talking ham radio, QRP and SOTA with kindred spirits. What an amazing couple!

Steve and Patty were actually on a multi-day camping trip in WNC and planned to hit two more summits by end of day. In fact, I got back to the QTH *just* in time to work Steve (ground wave!) at his second summit of the day. It was fun hunting someone I had just spent time with on a summit!

Steve and Patty: Again, it was a pleasure to meet you both!

Video

Here’s my real-time, real-life video of the entire Mount Pisgah SOTA activation:

A memorable activation indeed

Hazel and I both needed a little trail time that Tuesday morning. Hiking to the summit in the low clouds, taking in the views, enjoying a stellar activation and then meeting new friends? It doesn’t get any better than this.

I’ll say that I do love the Elecraft KX2 and CHA MPAS Lite combo. It makes for a compact and effective SOTA pairing that can be deployed so quickly.

A couple months ago, I ordered a SOTAbeams Tactical Mini fiberglass telescoping pole. I plan to pair it with my QRPguys tri-bander kit antenna.

If I’m being honest, though, I find that the CHA MPAS Lite is so quick to deploy–like 2-3 minutes tops–I’ve yet to take the Tactical Mini and Tri-Bander to a summit. No worries, though, as I will eventually deploy this pair on a summit. Admittedly, I need to work on my mast guying skills in advance–let’s just say that I’m still in that awkward stage of struggling to manage each guy line as I try to keep the Tacmini vertical during deployment. I welcome any tips!

DAY4: A SOTA Adventure To Remember (Conclusion)

June 17, 2021 Scott Lithgow 3 Comments

I hope the first two parts of my SOTA journey with Mark, NK8Q, has been interesting reading. It is really tough to put into words what the trip meant to me. Back in November I had my left knee replaced, and was preparing myself to possibly not be able to enjoy the luxury of being able to walk, run, hike and backpack. I never would have dreamed by the time this SOTA journey started that I already would have walked a half marathon on the new knee, nor be able to hike up summits. I have been truly blessed to be able to continue to do the things I enjoy. SOTA and POTA over the past year has renewed my interest in the hobby.

After we left Stony Man Mountain, we headed to the campground we were staying at along Skyline Drive. We lucked out earlier in the day by randomly arriving around 11:45 a.m. at the campground and even though the sign said it was full, the park ranger said to wait 15 minutes because there could be some checkouts right at the cutoff. We waited it out and at noon the ranger confirmed we had a campsite! Perfect…after 2 days of staying in motels, I finally got to camp in my new tent.

Once settled in, I thought it would be a good evening to set up my antenna and operate a little “late shift” on POTA – Shenandoah National Park (K-0064). I was just a bit too far off the A.T. to make it a “twofer”. This yielded 16 QSOs and then called it a night.

The next morning was also the last day of our SOTA trip. I woke up after a pretty restless night due to the fact my old body cannot tolerate being so low to the ground. I believe the last time I slept in an actual tent was in 1981 in boot camp at Parris Island. I am now a hammock camper and it sure feels much better on the back. So, back to the story. After breakfast we packed up and drove to the first of two SOTA summits before heading home.

The first was Pinnacle Overlook (W4V/SH-005). The climb took an unexpected wrong turn from the parking lot but quickly rectified. The hike to the summit was fairly steep, but there was beautiful flowers and rock formations and the summit was aptly named The Pinnacle. What a beautiful view of the Shenandoah National Forest.

We saw several thru hikers on our hike both up and back down the mountain after the activation. Several were interested in our ham radio operations. I found a perfect spot to operate from right along the Appalachian Trail and off to my left I could look over and see the view. I had 20 QSO’s and the bands were in decent shape.

It was time to head back down to the parking lot and continue our journey to the next stop, Hog Back Overlook (W4V/SH-007). There wasn’t much of a view once we climbed to the top of Hog Back, but met more through hikers, including one lady who was wearing a hat from Boston Marathon. Her trail name was GiGi, which is her Grandma name, which is also my wife’s Grandma name. She decided at age 65 she was going to hike the entire A.T. and had already run the Boston Marathon, so this was a bucket list item for her. I told her hiking the entire A.T. is my goal in 2026 when I’m retired and was nice to know there are hikers in our age group that are still able to accomplish these things. We gave her some trail magic, and Mark and I continued on our way to the top of the summit. There wasn’t much besides an old building which may have been a ham radio shack at one time, and some towers but not much of a view. We did a fairly quick activation and I had 12 QSO’s before packing it up. (I almost thought I heard the sound of banjos playing up there.)

We made a couple of other stops along the Skyline Drive, one was for the tunnel that was built along the route, and another stop to see the scenery from the outlook. It was time for me to start heading back to Lancaster County, which was about a 4 to 5 hour drive and Mark had two other summits he wanted to visit. What I did not expect to see at the one stop to look at the views was a lady who was sitting along the rock fence painting. I asked her if I could take a picture of her holding the picture she was painting and she gladly agreed. It took her about an hour to paint it and was finishing up when I arrived. After I left I regretted not thinking to ask her if I could have purchased the picture!

I arrived home around 5:30 pm on that Sunday evening and was completely exhausted. Mark sent me a text and told me at his next summit he was on the trail and saw GiGi again.

Thankfully, I had taken Monday off for a vacation day because I was exhausted from all the traveling Mark and I had done in 4 days. In addition to the driving, we did a lot of walking to the summits and operating. It was an experience neither of us will ever forget. We are already starting to plot our plans for next year for another adventure.

I’d like to thank Mark for putting this trip together and plotting out which Summits to do on each day and the best way to navigate to each destination. The hikers on the trail were all wonderful, and some of them asked questions about what we were doing, especially when we had our fishing poles at the summit with no trees. I used the HAMRS program for the 4 days, and other than some operator error, the program worked flawlessly. I especially would like to thank Thomas Witherspoon for allowing me to share my story on QRPer. Tom is an awesome ham and we share many of the same interests for POTA or SOTA, and we both enjoy antenna experimenting and our passion for QRP operating. Thank you again Thomas for the opportunity to share my experience, and I hope you enjoyed my SOTA experience.

SOTA: Activating Bearwallow Mountain with the KX2, MPAS Lite, and Hazel

June 13, 2021 Thomas Witherspoon 6 Comments

The MPAS Lite vertical has an impressive view!

I’ve been receiving a lot of comments lately from readers and viewers asking to see more Hazel in my reports and videos.

Hazel, if you’re not familiar, is my brown, white, and freckled canine shadow.

Hazel requires absolutely no prep time to go on a hike and summit/park activation. She’ll go from a deep, dreamy sleep where she’s chasing squirrels and her paws are twitching, to wide awake, tail wagging and nose pointed at the door in 2 seconds flat.

All it takes is the sound of me putting on my hiking boots (which must be louder that I imagined).

On Monday (May, 24, 2021) the weather was beautiful and I decided to finally add Bearwallow Mountain to my list of SOTA activations. Hazel was ready for a short hike!

Bearwallow Mountain (W4C/CM-068)

Bearwallow is one of the most popular summits to activate in the Asheville/Hendersonville area of western North Carolina. Any semi-seasoned local SOTA activator probably has Bearwallow in the logs. Why?

The Bearwallow antenna farm is extensive!

For one thing, Bearwallow is a ham-friendly site. A number of local repeaters are on this mountain and some of our local clubs have access to the summit. Once–I can’t remember the year–I even spent time with a club (I believe it was the Roadshow ARC) on Bearwallow for the ARRL Field Day. It was a blast!

Bearwallow is also a very accessible summit.

The trailhead to the summit (Google Map) is tucked away in the Upper Hickory Nut Gorge area–and there’s ample paved parking unless you happen to pick a very busy day (basically, any weekend with good weather will be busy!). Hazel and I were hiking on a Monday morning, thus there was very little activity and loads of parking spaces.

Some years ago, Conserving Carolina acquired the summit and much of the land on Bearwallow Mountain. Their conservation easement protects this area from future development and opens it for the public to enjoy.

Conserving Carolina maintains the trail system to the summit and all of the hiker information and blazing.They do a brilliant job!

There are two options for hiking to the summit: a proper foot trail, or you can take the Fire Tower Road which is the best choice for hikers who need a more gentle incline and flat gravel hiking surface.

Click here for a map of the trails (PDF).

Hazel and I decided to go up the foot trail and descend via the Fire Tower Road to make a loop.

We spotted a number of plants in bloom on the way up.

The foot trail is an easy one to hike, too. It’s well-maintained, as I mentioned, and there are only a couple of steep-ish sections.

There are even opportunities to take in views on the trail.

When you reach the top of the trail, it opens onto a pasture.

And the views are panoramic!

There are cattle all over the summit, so give them wide berth.

Speaking of cattle, Hazel is quite fond of them…or at least what they leave behind.

She’s been known to roll in cow patties when she has the opportunity (or if I’m distracted with something else…like performing an activation!).

Hazel and I found a nice spot to set up the station well within the activation zone. On summits like Bearwallow where there are clusters of communications towers, I prefer not to set up next to them. This is where that 25 meter SOTA activation zone (AZ) comes in handy.

Gear:

Elecraft KX2
Chameleon CHA MPAS Lite
GoRuck GR1 USA
Tom Bihn Large Travel Tray
Rite In The Rain Weatherproof Cover/Pouch (affiliate link)
Jovitec 2.0 mm Mechanical Pencil (affiliate link)
Muji A6 Notepad (affiliate link)

I had actually planned to use my Elecraft KX3 on this activation, but after setting it up, I realized quickly that my power cord had developed a fault.

Fortunately, I packed a spare radio.

Knowing in advance that this would be a short hike–before leaving the QTH–I also packed the KX2 kit in my backpack as a backup. I don’t always have the luxury of packing a second radio, but wow! Am I glad I did that Monday!

Setting up the Chameleon CHA MPAS Lite vertical, of course, was super easy.

On the Air

I started the activation on 20 meters and spotted myself to the SOTA network via the SOTA Goat app. Of course, before leaving home, I had also set up an alert on SOTAwatch so that the spots page would auto-spot me via the Reverse Beacon Network (RBN) if I didn’t have mobile phone coverage.

In short? The contacts started rolling in. I was very surprised to have this sort of response on a Monday morning.

In 22 minutes, I worked a total of 19 stations including one summit to summit (S2S)–thanks for that, Eric (VA2EO)!

I was very pleased with the number of contacts logged in such short order because I only had a max of 25-30 minutes to be on the air before I needed to pack up and head back to the QTH.

Here’s the full log:

Activations like this one remind me of what one can do with QRP power and a modest antenna.

Sure, at one point–after I had worked at least my first four to achieve a valid QRP SOTA activation–I increased the power from 5 watts to a cloud-scorching 10 watts! 🙂

Here’s a QSO map of the contacts:

Video

Here’s my real-time, real-life (a.k.a. it’ll put you to sleep) video of the entire activation:

I must apologize for the audio in this one–it’s a little weak due to how the camera was set up.

Hazel at it again

So I brought along a retractable leash/lead for Hazel for this particular outing.

This leash allows her to roam more freely during our actual hike. On the summit, I locked the leash and attached it to my pack so it would keep her within 4 feet or so of where I was sitting which was cow patty-free.

At one point, near the end of the activation, when I was trying to manage a few calls, off-camera Hazel discovered that the leash unlocked, allowing her more flexibility to roam.

I looked up to discover that she found a semi-moist cow patty I somehow missed and was preparing to “enjoy” it. While sending CW and trying to keep from knocking down the camera, I used my left foot to put the brakes on her leash. She knew I was struggling, though, and tugged more.

I managed to stop her before even one paw plopped in the patty. Somehow. It was a very close call, though.

If you’ve watched my activation videos before, you’ve no doubt gathered that I’m not a multitasker. This little event really tested my ability to hold it all together on and off camera! 🙂

After packing up the station, Hazel and I took the Fire Tower Road back to the car. It was a very pleasant stroll and cow patty free.

Thank you for coming along with me on this SOTA activation and making it to the end of the report. You deserve an award! Please treat yourself to a local summit or park soon!

Thank you & 73,

Thomas (K4SWL)

Days 2 – 3: A SOTA Adventure To Remember (Part 2)

June 9, 2021 Scott Lithgow 8 Comments

I would like to thank everyone for their positive and kind comments from my first part of the SOTA adventure with NK8Q. I have a slight correction to make, Cole Mountain was the first summit we did on Day 2. As you can see below in the pictures, there were no trees to hang our EFHW antennas, so we brought along our fishing poles. This generated a lot of interest from the A.T. thru hikers asking what we were doing. On particular hiker told us he’s seen others doing SOTA at summits throughout his journey from Georgia until that day. This was a fairly steep climb to get to, but the scenery was fantastic and well worth the walk. We offered trail magic to several of the hikers and we had very good conversation with them all.

Heading back down from the summit are a couple of other views we saw. There were some trees outside of the activation zone.

We packed up and started heading down the mountain to the parking lot around noon with the next destination Rocky Mountain (W4V/BR-001).

We drove almost 3 hours to get to this drive-up summit. The “S” turns and elevation changes were worth it though as there was so many spectacular views of the mountains. The last 4 or 5 miles was up a very steep gravel road that had me white knuckling until we got to the top. This was a site with several towers for different things and not a lot of view. I was able to get 10 QSO’s at the summit. I recall it was getting very warm that afternoon and I was not looking forward to the drive back down the mountain on the access road. I figured out how to do the manual shifting in my Tucson and Mark followed me down the hill. It was a non-issue and then we had a long drive to where we thought we would be able to camp on Skyline Drive.

When we finally got back onto paved roads and eventually into cell phone coverage briefly; we were hoping to find a place to get ice for the coolers and maybe a place to eat. Well, we found a gas station in the middle of nowhere with ice and a little store and they happened to be selling their own fried chicken and fries. When we got to the south end of Skyline Drive entrance, the sign showed all of the campgrounds were full. Since it was already getting dark, we made the decision to get on I-81 and head north and found a Super 8 Motel in Newmarket, VA for the night with the plan to get back to Skyline Drive at the Thornton Gap entrance. We got up early and looked for a gas station and a place to eat. Conveniently, Dunkin Donuts has a gas station as well (we didn’t realize that until after we got gas) but had a good breakfast sandwich each and I got a large coffee. I believe Mark is only the second person I’ve ever known who does not drink coffee. I believe my large cup was consumed before we got to Skyline Drive that morning, which I believe was about 18 miles.

First Summit of the day was Hazeltop Mountain (W4V/SH-004), which was south on Skyline Drive. The scenic outlooks were beautiful on the way to the summit.

Once we reached the summit, there was not much to see. I set up a few yards off the A.T. and made 15 contacts. The band conditions were pretty decent. This was my set up at this location.

Next stop – Hawksbill Mountain (W4V/SH-001). It was just after 12 noon when we got to the parking area, and there was a good mile or so of steep uphill climbing. The reward at the top was worth the climb! I got another 20 QSO’s in the logbook at this summit.

This dial pointed to the many summits within view of Upper Hawksbill.

Final summit for the day was Stony Man Mountain (W4V/SH-002). This was another steep climb, but the reward was also a beautiful view. I made 8 QSO’s and Mark and I shared the antenna and radio due to the limited space and all the people walking around at the summit.

I will continue with Part 3 of our journey to the Summits in Virginia in the next post. I hope I have half the writing skills that Tom Witherspoon has and that I was able to hold your interest in the SOTA journey that Mark and I did. I will wrap up the story with a Part 3. Thank you for taking the time to read this.

A memorable Bakers Mountain SOTA activation with the Elecraft KX2 & PackTenna 9:1

June 4, 2021 Thomas Witherspoon 6 Comments

Besides Lane Pinnacle, there’s been one SOTA summit, in particular, I was eager to activate this year: Bakers Mountain (W4C/WP-007).

I practically grew up in the shadow of this little outlier mountain in Catawba County, North Carolina–my home was only a couple miles away as the crow flies and it has always been a bit of a landmark in my childhood stomping grounds.

Growing up, the land in/around Bakers Mountain was basically off-limits and privately owned. In the late 1980s, one of the land owners gave a large tract of land to the county to protect it from development (which started booming in the area around that time).

In June, 2002, while I was living in the UK, Catawba County open up the 189 acre park and its 6 miles of trails to the public.

I love Bakers Mountain park. Even though the mountain isn’t terribly tall (1780 feet/543 meters ASL) parts of the trail system are fairly strenuous. When I want to escape and clear my head, the Bakers Mountain trails are the perfect medicine.

Bakers Mountain: What’s in a name?

An interesting tidbit about Bakers Mountain that I learned from one of the park rangers: it was originally called “McBride Mountain“ in the late 1700s, but as more German settlers moved into the area, German family names became predominant.

The Baker family had large tracts of land in/around the mountain and, locally, people started referring to it as “Baker’s Mountain” sometime in the 1800s and the name stuck.

Officially, the name of the mountain is “Bakers Mountain” although, I suppose, it should have been called “Baker’s Mountain” or maybe “Bakers’ Mountain.” An apostrophe was never added, though.

It’s a source of confusion for those who make maps and refer to the mountain. In the SOTA database, it’s referred to as “Baker Mountain.” That is incorrect, of course, but the SOTA database is likely built upon one of the topographic map databases where it’s incorrectly labeled.

So there you go. Tuck away this bit of trivia and sound like a local next time you’re in Catawba County!

Now where was I? Oh yes…

So on Wednesday, May 19, 2021, I packed my Elecraft KX2 and PackTenna 9:1 UNUN antenna in the GoRuck GR1, and hit the Bakers Mountain trail system.

The weather was perfect, although the humidity was incredibly thick that day.

Mountain Laurels were in bloom and flanked portions of the trail.

I took the main red-blazed loop trail.

The trail is very well-marked and maintained with maps posted throughout.

At one point, you’ll happen upon the old home site.

The trail has a few steep sections, but overall is pretty moderate.

There’s no missing the summit trail.

Following the orange mountain top trail will take you to a gazebo and observation deck near the summit.

Keep in mind, though, that this is not the true summit of Bakers Mountain and isn’t close to the 25M SOTA activation zone. Still, the views are fantastic here, so take a breather and soak up the Catawba valley.

Click the pano image below to enlarge in a new window.

To find the trail to the real summit, you must follow the path crossing under the power lines near the observation area–you can’t miss it. While the public isn’t encouraged to take this path–and it is not a part of the Bakers Mountain trail network–a park ranger told me that the current owners don’t mind the odd SOTA activator following the trail to the summit.

The path–since it’s not a part of the public trail–is a bit overgrown. Follow this path until you intersect an overgrown narrow access road. At the intersection take a left and this will lead you to the true summit. The ring road around the summit is well within the AZ.

I found a little spot to set up among the trees on the summit. No views, but it was the perfect space to deploy the PackTenna 9:1 UNUN!

Gear:

Elecraft KX2
Packtenna 9:1 UNUN Random Wire Antenna

On The Air

This being my first time activating Bakers Mountain, of course I made a real-time, real-life, no-edit video (see link below). Sorting out a way to set up the camera position took me longer than deploying the antenna and unpacking the radio! It can be a real challenge on a stony mountain summit.

The KX2 paired beautifully with the PackTenna 9:1 UNUN. I got a great match on 20 meters.

I started calling “CQ SOTA” and spotted myself on the SOTA network using the SOTA Goat app.

My first contact was SA4BLM in Sweden–I almost fell off of my rock!

Next, I worked KR7RK in Arizona, AE0XI in South Dakota, and HA9RE in Hungary! All in eight minutes.

Wow!

Next, I moved up to the 17 meter band where I logged AC1Z in New Hampshire, F4WBN in France, and KT5X in New Mexico.

Finally, I moved down to 40 meters where I worked K3TCU in Pennsylvania, K8RAT in Ohio, W4KRN in Virginia, and K4MF in Florida.

My total activation time was about 25 minutes.

QSO Map

Here’s the QSO Map plotting out my QRP contacts. I must say, that modest PackTenna did a lot with my 5 watts! That and some good Bakers Mountain mojo! 🙂

Video

Here’s my real-time, real-life, unedited video of the entire activation from start to finish:

Click here to view on YouTube.

That was fun!

When I hike at Bakers Mountain, I add spur trails and connectors to make it as long as can in the time frame I have. The trip back to the car was actually a longer hike than it was to the summit.

But I had a spring in my step.

I was absolutely chuffed that my first activation of this particular summit was so exciting and fun. It still blows my mind what can be accomplished with 5 watts and a modest wire. I can’t wait to go back again.

Day 1: A SOTA Adventure To Remember (Part 1)

June 3, 2021 Scott Lithgow 6 Comments

First of all, thank you so much Thomas Witherspoon (K4SWL) for allowing me the space to tell my recent story from my trip to Virginia. I hope you find it interesting. I certainly do not have Tom’s writing skills so I’ll do my best.

A quick introduction. I was licensed in 1983, call KA3LUW, as a Novice mostly a CW operator. I upgraded in 1992 to Extra with the 20 WPM code. I was mostly interested in DX and around 1996 went through some life changes and became inactive for several years until about 2003 when my Dad (N3FWI – now SK) gave me his Kenwood TS 450 to sell. I put up a temporary antenna and discovered PSK31. That actually got me back into ham radio as Dad let me keep the radio. At that point I changed my Extra call from WY3X to KN3A. Over the years my interest is still chasing DX and contesting. In 2015, I was chasing the W1AW year long event for the ARRL Centennial so I could confirm as many states on as many bands and modes as possible. When 2016 started, my ham friend, Mark, K3MRK told me I should get involved with NPOTA (National Parks on the Air) which was also celebrating their 100th anniversary. I was just so burned out from ARRL the prior year that I did not get involved. My interest in the hobby also started to wane as well, as I got into fitness due to health issues.

Fast forward to 2020. Mark continued to praise the now POTA program and all the fun he was having with it. It seemed to be something I would also enjoy as I could walk, hike and exercise as well as discover portable operations. On March 14, 2020, Mark convinced me to do a POTA activation with him at the local Sam Lewis State Park (K-1418) near my QTH. It was very cold and windy but we had a successful activation and I was hooked. Since then I’ve done 75 activations from 9 unique parks in 3 states. To say I am hooked is an understatement!

I have another good friend Mark, NK8Q, who is an avid Summits on the Air activator and chaser (SOTA). Mark lives about 2.5 hours west of me, and last summer we met and activated two Summits together. The first was a drive up summit and the second one required a little bit of hiking to reach the summit. I like the idea of walking, hiking and backpacking so SOTA is also something I enjoyed doing last year.

Two years in a row K3MRK and I have tried to get to Dayton, only to have them cancel due to the pandemic. I had scheduled a week off of work and decided to keep the time off and contacted Mark – NK8Q about possibly doing a backpacking SOTA adventure.

We talked about different places we could go to activate, and ultimately we decided to do several 10 point summits along the Blue Ridge Parkway, Skyline Drive and along the Appalachian Trail. For me, this was going to be not only a SOTA activation, but in some instances the activation also counts for POTA. We both left our homes early morning on May 20 and meet in Natural Bridge, VA and we would spend the next 4 days heading north, while activating different summits. We actually realized about 100 miles north of Natural Bridge that Mark and I were only about a mile apart heading south on I-81, so we took advantage of 146.52 simplex the rest of the way to our starting point and we used FM simplex driving from summit to summit.

We arrived at Natural Bridge just before 10:00 a.m. and Mark asked if I wanted to activate K-3972 (Natural Bridge National Park). Sure, why not, it would be fun to do a quick activation. We found a nice spot to set up the antenna and radio. My equipment for this journey was a Sotabeams Bandspringer Midi and my ICOM 705. I put 11 QSO’s into the log the short time we were there and was a nice warm-up for what was ahead.

After the quick POTA activation, we started heading to our first summit, which was Apple Orchard Mountain (W4V/RA-001). This was along the Blue Ridge Parkway and the views heading there were spectacular. Once at the summit we explored the area and then found our operating spots. I made 20 QSO’s and 3 S2S (summit to summit).

Second summit was Cole Mountain. The parking area was about 700 feet below the summit of 4,020 ft. Most of this climb was along a private road that goes up to several towers and they were cutting the grass. They waved as we walked up and were also very close to the Appalachian Trail (AT). Cole Mountain yielded 27 QSO’s in a very short period of time.

We hiked back to the parking lot and proceeded to our next summit of the day at Petites Gap Trailhead where we went to Highcock Knob (W4V/RA-014) where we hiked about 700 feet in just over a mile. This was a fairly rocky and difficult climb and being tired from other summits and the drive down first thing in the morning, it was nice to be the last summit of the day. The elevation at the peak is 3,073. Mark and I had some issues getting our antennas through the trees at this summit and wasted a lot of time. Once the issue was resolved, I made 8 QSO’s. Mark and I decided it was time to start heading back to the parking area and call it a day. Since we were on the Appalachian Trail, we met many thru hikers heading from Georgia to their final destinations in May. Every one of them were really nice and eager to find out what we were doing at the summits and we made sure we had “trail magic” as they call it on the A.T. We carried extra water and snacks, and they were always much appreciated by the hikers. Just before we got back to the car, we met up with a hiker from Minnesota who was hanging his bear bag in a tree and he was preparing to camp for the night. When Mark and I got back to the car I thought, here I am with a cooler full of ice cold beer, I bet this man would appreciate a beer or two. I went back and he couldn’t get to the car fast enough! If you are ever hiking on the A.T. make sure you bring some trail magic as well. In the picture below, Mark was using my rig and we were right at the summit.

We left and went looking for a place to camp for the night. There were no campsites available so we stayed in a very old motel that I was afraid was going to be full of bed bugs or something. We survived and day 2 of the SOTA adventure was ready to begin.

Organizing and packing field radio accessories–three products I love!

May 21, 2021 Thomas Witherspoon 7 Comments

As I was packing up my radio gear at the last activation I posted (click here for that field report), I paused to make a quick video and talk about my rucksack, my accessories pouches, and a winder I like to use with the MFJ-1984LP antenna.

Here are the products I mentioned:

GoRuck GR1 USA

This is one of my favorite rucksacks for SOTA activations. I like the fact that it’s low-profile, structured, and feels great on the back even during extended hiking sessions.

It’s also insanely rugged, weatherproof, and (frankly) over-engineered.

My GR1 was made in the USA by GoRuck. This company specializes in packs that are essentially designed to be used and abused. They’re all backed by a lifetime warranty. You pay for this kind of quality, though.

I purchased mine perhaps 3 years ago during a closeout sale on this particular color variant. When combined with my educator’s discount I think I paid around $210-220 US for it.

I originally bought it because I’m a huge fan of one-bag travel (read an article where I mention this on the SWLing Post). I discovered that the GR1 meets most airline regulations as a “personal carry on.” This means even with discount airlines and regional “puddle jumper” aircraft, I know I can always take it on board and never need to check it. I can easily travel one or two weeks out of this pack.

The TX-500, clipboard, and my logging pads all tuck away nicely in the GR1’s slip-in rucking plate pocket.

But in the field, the GR1 has the perfect amount of capacity for any of my QRP transceivers along with antennas, ATU, cables, and other accessories.

Large Tom Bihn Travel Tray

Being a one-bag traveller (and certified pack geek) I’m also a massive fan of US pack designer and manufacturer, Tom Bihn.

I have a number of their packs, pouches, and organizers.

Without a doubt, one of my favorite TB items is the Travel Tray. It’s a brilliant concept: take this with you on a trip, open it up as a tray in your hotel room, and place all of your valuables in it. By doing this, you don’t have to search your room for your watch, keys, wallet, glasses, phone, etc. When you leave the room, all of those easy-to-lose items will be in one place. If you’re in a rush to catch a flight, grab the whole pack by the drawstring, secure it, and throw it in your carry on! It’s a simple, genius little sack/tray!

I also use these to organize radio accessories in my field pack. For example, I have one now dedicated to the TX-500. In the Travel Tray, I store all of the TX-500 adapters and cords, the speaker mic, a set of CW Morse Pocket paddles, a PackTenna EFHW, some RG-316, and a 3 aH LiFePo4 battery. I even carry a spare Muji notepad in it in case I forget my logging pad. With this little bag and the TX-500, I have everything I need to hit the air!

Note that I much prefer the large TB Travel Tray. My wife has both a large and small travel tray, but I find that the small one is just a little too small for most everything I wish to put in it. The large one’s outer diameter is large enough that you can also store a short coil of RG-58 coaxial cable/feed line in it.

I love these so much, I purchased two more this week: one in black and one in coyote.

Thingiverse Wire Winder

This particular winder is red because that’s the filament my daughters had loaded in the printer at the time!

Before we purchased a 3D printer (an Ender 3 Pro) I would make wire winders out of anything I could find. With a 3D printer, however, it’s so easy to make a winder sized perfectly for your application.

You may have seen winders in various colors in my video field reports–they all come from a simple project file on Thingiverse.

This winder is super easy to print and to enlarge or shrink. If you don’t have a 3D printer, likely someone you know does! Ask them to print this for you. They’re incredible useful.

Activating The Pinnacle: Amazing SOTA & POTA fun with the Elecraft KX2 and Chameleon MPAS Lite

April 28, 2021 Thomas Witherspoon 10 Comments

Last Tuesday (April 20, 2021), I decided to make a detour to a park I had never visited before: Crowders Mountain State Park (K-2726).

It’s actually quite odd that I’ve never activated this park during the weekly trip to do a little caregiving for my folks: Crowder’s Mountain State Park is a reasonable detour especially compared to some of the more remote parks I’ve visited recently.

What’s really impressive about Crowders Mountain is that although it’s not as large as a national park and it’s very close to the city of Gastonia, it has no less than two unique summits that qualify for Summits On The Air: The Pinnacle and Crowders Mountain.

Both summits are accessible from the main park visitors’ center via a well-maintained trail network.

The propagation forecast looked pretty grim and after my last activation, I thought I might increase my chances of success by hiking to both summits in one visit. This made sense because I would only need 4 contacts per summit to have a valid SOTA activation and I could combine the contacts from each summit to hit 10 total contacts to activate the state park.

I decided to call the park and ask how long it would take to hike to both summits: the ranger told me “about 5 hours, or less if you’re fast.” That meant that once I added in my setup/pack up times and on-the-air time, I would be staring at a minimum of 7-8 total hours.

I (wisely) decided to pass on that opportunity. I simply didn’t have enough time in my schedule for that many hours at the park. That, and I didn’t want to feel rushed–I wanted to enjoy my outdoor time.

I decided instead to activate one summit and simply plan on spending more time on the air then plan to come back to the park for the second summit on a different day.

Before going to bed Monday night, I checked out the trail map and decided to activate The Pinnacle.

Crowders Mountain State Park (K-2726)

I arrived at Crowders Mountain State Park around 11:00 AM local–the weather was nearly ideal.

I had pre-packed all of the radio gear and supplies in my GoRuck GR1 rucksack, so once I arrived, I grabbed the pack, put on my hiking boots, a hat, and hit the trail.

I’ve read that Crowders Mountain State Park can get very busy and it’s no surprise as the park is within easy reach of Shelby, Gastonia, and the Charlotte Metro area. Fortunately, I was visiting on a Tuesday morning, and while I saw at least 30+ cars parked in the main parking lot, I passed other hikers only a few times on the Pinnacle trail. It’s a sizable park and can easily swallow 30 groups of day hikers!

I followed the orange-blazed trail to the summit of The Pinnacle.

The hike was very enjoyable and, frankly, not what I would consider strenuous, but it had enough elevation change to feel like a proper hike. I allowed an hour to reach the summit, but it only took about 40 minutes or less.

Near the summit, there’s a fork in the trail: if you take a right, it leads to the summit, if you take a left, it’ll lead you on a much longer Ridgeline Trail that will eventually take you into Kings Mountain State/National Park–you’d better believe I’ll try that one day in the future! It would be fun to activate two parks and a summit all on foot.

I took a right at the fork and the .2 mile long trail zig-zagged up the side of The Pinnacle.

I was a little surprised to be greeted by the sign above. It’s true that the summit area is quite rocky and you have to watch your step, but this warning is a bit extreme in my opinion (especially since the SOTA activation I did with my daughter recently was orders of magnitude more dodgy!).

If you are activating The Pinnacle and don’t want to climb up the rocky path, no worries. I’m certain the area where the sign is located is well within the SOTA summit activation zone.

The Pinnacle (W4C/WP-010)

Although The Pinnacle is only a “one point” summit, when you reach the top you’re greeted by some impressive views.

The Pinnacle and Crowders Mountain are both outlying mountains so are the tallest points in the area offering beautiful, long-range vistas.

There were perhaps a half dozen hikers hanging out on the summit. I found a quite spot to set up on the side of the summit only a few meters from the top.

Gear:

On The Air

During the hike, my buddy Mike (K8RAT) sent a text noting that propagation on 40 meters was non existent. He suggested I play on 20 meters and above, possibly including 30 meters.

Later on, I found out that Mike was 100% correct. Several POTA activators that day mentioned on the POTA Facebook group that 40 meters was completely wiped-out.

I installed the Chameleon MPAS Lite vertical antenna next to me. I’ll admit that I was a little worried it might be too rocky to plunge the MPAS Lite’s stainless spike in the ground, but it turned out not to be the case.

The CHA MPAS Lite has really proven itself as an invaluable SOTA antenna. While the stainless spike adds weight to my pack, it’s less fussy than dealing with guy lines and telescoping fiberglass poles and much quicker to set up. You do need enough ground to plunge that spike into, but if there are trees and bushes on the summit, it’s probably doable!

I started recording a video (see below) of the activation, spotted myself to the SOTA network (even though it would have likely auto-spotted me via the Reverse Beacon Network) and hopped on 20 meters.

Solar Flare!

I had no idea at the time, but we were experiencing a solar flare which explained why 40 meters was completely wiped out.

The effect on 20 meters was simply epic.

I called CQ and was instantly rewarded with a long, continuous string of stations. Within 26 minutes, I had already worked 23 stations with 5 watts and the MPAS Lite vertical. A stark contrast to my previous POTA activation.

And here’s the thing: the flare opened up 20 meters to local/regional stations as well. I worked stations as close as South Carolina, Georgia, and Tennessee–this is simply unheard of normally. Of course, stations on the west coast were also booming in.

I was a little surprised I didn’t log any European stations on 20 meters, but I suspect they were having a difficult time competing with the strong signals from North America during the flare.

I short: the band opening was amazing fun and even renewed my faith in our local star just a wee bit. (Ha ha!)

After playing on 20 meters, I decided to try 17 meters.

Wow! Without a doubt, I worked more stations on 17 meters in short order than I’ve ever worked during a field activation. In 10 minutes, I worked 12 stations. As with 20 meters, the flare opened up stations that would normally be in my 17 meter skip zone.

Here I was worried about logging the ten stations needed to validate my park activation! After logging 35 total contacts, I decided to pack up.

Here’s a QSO Map of the activation (click to enlarge):

Here’s one of my unedited real-time, real-life videos of the entire activation:

Although the weather app on my phone wasn’t showing any afternoon thunderstorms nearby, there were some patchy dark clouds forming on the other side of the summit and the winds were shifting, so I decided to call it a day and enjoy the hike back down the mountain.

Fortunately, the clouds never amounted to anything but I don’t take my chances with spring weather–it’s fickle, especially along the North Carolina/South Carolina line. That, and frankly, I needed to stick to my travel schedule.

I took my time on the way back down and simply soaked up the outdoors.

I love doing field activations of all types, but I’ll admit that I’m becoming addicted to Summits On The Air because of the hiking opportunities it presents.

There are few things in the world I enjoy more than hiking.

When I’m on a trail, all of my concerns seem to dissolve.

Perspective

On the return hike, I passed by a group of three hikers. All of them were staring at their phones while hiking and one tripped on a tree root in the path. They caught themselves before hitting the ground.

I’ll admit I was thinking at the time that mother nature was saying, “Hey! Wake up, disconnect and enjoy the beauty around you! You need some perspective!” 🙂

I’m already looking forward to visiting Crowders Mountain State Park again. I believe I’ll return within a month and hike to Crowders Mountain, activating both the summit and park.

Sometime, I’d like to hit the trails as soon as the park opens and, perhaps, activate both Crowders Mountain and Kings Mountain parks on foot. That would likely take an entire day when I include the time on the air, but it would also be a lot of fun.

I was telling my wife yesterday that I actually enjoy writing up the odd field report on QRPer. It hit me that there are a couple of reasons why…

For one, a number of readers have reached out and thanked me because they enjoy living vicariously through my field reports and videos. I get it. My family and I enjoy watching YouTube videos of travelers around the world. We avoid the personality-driven channels and focus more on those that are less “produced.” It gives us an opportunity to travel to, say, Spain, France, Finland, or Turkey when we can’t presently do so. It pleases me to no end thinking that my reports and videos could, even in some very small way, offer a little vicarious travel to others.

Secondly, writing up these reports gives me an opportunity to re-experience some of my field time and sort through photos I might have taken along the way. Although it takes a few hours to write a report, I truly appreciate the experience.

Thank you, dear reader, for spending time with me during this outing!
