New River State Park: Pairing the Discovery TX-500, Elecraft T1, and PackTenna 9:1 UNUN

Last month, my family went on a camping trip to New River State Park and had an amazing time.

I first discovered New River much earlier in the year when I did a multi-park and summit run.  I really liked the park and, especially, the campground, so I decided to return with the family for some proper outdoor fun and relaxation.

Of course, the benefit of camping at a state park is being able to play radio pretty much anytime while on the park grounds. For a few days, it’s like you’re living in a park activation and can actually set up an antenna and use it over the course of multiple days.

It’s such a big departure from my typically short (45-90 minute) park activations.

When we first arrived at the New River State Park campground, I deployed my PackTenna 9:1 UNUN random wire antenna.

I brought two transceivers with me: the Xeigu X5105 and the Discovery TX-500–I pretty much split my operating the time equally between the two radios.

New River State Park (K-2748)

Although I spent much more time on the air than I normally do, I didn’t make videos of each session. One reason is I wanted to operate with earphones–especially since some of my sessions were later in the evening or early in the morning. I didn’t want to disturb my neighbors at the campground.

That and, especially with the X5105, I wanted to see what it would be like to operate with earphones for extended sessions. Prior to making videos of my activations, I almost exclusively used earphones in the field. I appreciate the sound isolation earphones offer–I also find they help tremendously with weak signal work. When I make videos, however, I don’t want to go through the hassle of recording the line-out audio separately in order to use headphones, so I use an external speaker.

I decided to record my Wednesday, June 23, 2021 evening session with the Discovery TX-500.

Gear:

This session started only a few minutes prior to the end of the UTC day which meant I had to watch the clock very carefully and clear my logs at the beginning of the UTC day (20:00 EDT).

In POTA and other field activities, if your activation straddles the UTC day change, you must keep in mind that any contacts made after 0:00 UTC can only be counted on the next day’s logs. This was not a problem for me because I had logged dozens of stations earlier in the day, but if you ever start an activation close to the UTC day change, you need to make sure you log your 10 contacts for a valid activation prior to 0:00 UTC.

Auto-spotting help

Another thing complicating my sessions at New River State Park was that I chose not to schedule my activation via the POTA website prior to our trip.

If you schedule your activation via the POTA website, anytime the Reverse Beacon Network picks up your CQ calls (in CW), the POTA spots website will scrape that information and auto-spot you.  It’s an amazing convenience for those of us who operate CW.

I chose not to schedule my activation days at New River because I had also planned to operate at another nearby park during my stay and I didn’t want the system to spot me incorrectly. That, and I thought I would have mobile phone coverage to self-spot.

It turned out that–contrary to my mobile phone company’s coverage maps–I had no internet service at the park. None.

In order to get spotted, I relied on my Garmin InReach GPS/satellite device to send short text messages to my buddies Mike (K8RAT) and Eric (WD8RIF). My pre-formatted message would prompt them to check the RBN for my frequency, then spot me to the POTA site manually.

I’m incredibly grateful to have had them helping me in the background. Everyone should have a Mike and Eric as friends!

Video

I made a real-time, real-life, no-edit video of the entire activation. Note that it took a while to get spotted, so the first ten minutes are simply me talking (it’s alright to skip that bit…it won’t hurt my feelings!).

Also, here’s a QSO map of that day’s contacts. Note that this includes stations I logged later in the UTC day (i.e. the following morning/day.

Due to some unexpected conflicts, our camping trip was shorter than we would have liked. We plan to visit New River later this year and spend much more time there. It’s a beautiful park!

Thanks for reading this short field report and here’s hoping you get a chance to play radio in the field soon!

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

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:

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.

Thank you

I’d like to thank all of you for reading this field report and I’d especially like to thank those of you who contribute to QRPer.com via Patreon and our Coffee Fund. While my content will always be free and QRPer is very much a labor of love, your support helps me purchase gear and supports my radio travels. With that said, if you’re saving up for your first radio or need to invest in your own kit, I’d rather you support yourself!

My goal with QRPer is to champion field radio operations and encourage others to discover the benefits of playing radio outdoors!

Portable Ops Challenge: September 4-5, 2021

If you’d like to participate in a contest that balances the playing field between fixed, high-power stations and QRP portable stations, you might take a look at the 2nd annual Portable Operations Challenge.

The POC will take place September 4-5 during three, 4 hour periods. The exchange is very simple: your 4 character Maidenhead Grid Square. You can even combine this event with a scheduled summit or park activation. 

This contest even includes prizes for the winners.

Check out the POC webpage for full details. I’ve pasted details from the POC page below:


PORTABLE OPS CHALLENGE

The Fox Mike Hotel Portable Operations Challenge is designed to optimize equal operating conditions for portable operating during a contest involving non-portable stations. The scoring allows and encourages regular home-based station operations to take part while offering a handicap-style scoring algorithm to be more equalized for portable stations. The approach is akin to the handicap index in the sport of golf. More difficult courses are scored with a higher slope value, indicating a greater challenge to achieve a normal par score of 72 on that course with a handicap of subtracting strokes for golfers who do not typically shoot as low a score as other golfers. A number of factors go into deriving the slope rating for a golf course but they represent the challenge that the course presents to each participant golfer and the golfer’s capability for playing the course.

The POC aims to make portable operations “on par” with more typical fixed-based operations while preserving the enjoyment of being in a new operating environment. Moreover, fixed-based operators can also easily participate in the action, challenging the handicapped-scoring for portable ops. Can the Super Station contester best the Little Pistol portable operation? If we use a scoring metric that reduces the advantages of fixed stations to that of pure radio sport operating, is there a chance that an efficient portable operator or team can come out ahead of the current winning contest station operators? That’s why this is called the Portable Operations Challenge!

Frank K4FMH

THEORY OF THE CONTEST SCORING FACTORS

Several aspects of fixed (permanent)-station contesting can be stacked in the operator(s) favor when compared to most portable operations. One is the use of greater RF power output. Another is a permanent tower with directional, gain producing beams. A third is that it is easier to have multiple transceivers and operators, allowing for a “per-transmitter production” that yields superior scores. A fourth is the mutual attractiveness for fixed-station ops to work other fixed-station ops and ignore the weaker (especially QRP) signals. The addition of having the full force of Internet communications (when allowed), spotting sources, better ergonomics for operating positions, food/drink conveniences, and climate-controlled shelter all add-up to give “course advantages.”

While some portable operations (an example can be some large Field Day teams) can meet or exceed the advantages to contesting identified above, the vast majority do not.

Our scoring metric equalizes some of these advantages. Four factors are used in scoring each contest operation submission. These are the same regardless of whether it is a single operator or a team of operators, unassisted or assisted through the use of operation spotting. These include:

a. Kilometers-per-watt (KPW). Using the Maidenhead Grid Square, the distance in miles divided by the reported power output in watts for the reporting contest participant.

b. Fixed (permanent) vs Portable operation (favoring portable).

c. Mode of contact: Phone vs. CW vs. Digital (favoring phone over CW over digital)

d. Number of transmitters in use (points X 1/t where t = # transmitters)

The logic underlying this metric is as follows:

The KPW metric will tend to equalize power used as well as antenna gain. The km-per-watt is computed per-contact using the centroid lat-lon of the Maidenhead grid square exchanged during the contact. Favor goes to the greater miles-per-watt which equalizes to some degree the antenna gain, power, and point-to-point propagation conditions. The MPW is the basic contact score. Fixed (permanent) station operators have their resident setup which gives an advantage over portable ops, although a team could replicate a Field Day setting with portable crank-up towers, amps, generators, and so forth. Favor goes to the portable operator. The amount of this multiplier can be adjusted much as a competitive “tuning parameter” in future contests.

All things being equal in a QSO, phone is most challenging, followed by CW and then digital (especially weak signal modes like FT8). Favor goes to phone first, CW second, and digital third.

The more transmitters shape the number of contacts so more transmitters get increasing decrements in the points awarded, regardless of the number of ops. This emphasizes the per-transmitter production rather than just the amount of equipment and number of operators. We are experimenting with what seems appropriate discounts for the number of transmitters in simultaneous so as to render a more equitable competition, favoring sport over equipment.

943 Miles Per Watt with the Yeasu FT-817ND, Elecraft T1, and 28.5 feet of speaker wire

When it comes to parks, I haven’t picked up many new-to-me “uniques” lately.

In truth, though, I’ve put more effort into activating unique summits which takes more time to plan, plot, and activate. SOTA has taken a bite out of my park uniques, but I’m good with that because to me it’s less about my park/summit numbers and more about the exploration and outdoor radio time.

On Tuesday (July 6, 2021) however, I added one more unique to my 2021 park count: Mountain Island Educational State Forest (K-4858).

This park is actually a modest detour during my weekly travels, but I’ve never popped by for an activation. You see, unlike other state parks I visit, Mountain Island isn’t yet open to the public on a daily basis. On their website, they state that visits must be arranged in advance, so I reached out to them the morning of July 6 and they promptly replied, welcoming me for a visit and activation that very same day!

Off the beaten path

Since this state park isn’t yet open to the public, I didn’t see the typical brown highway signs pointing me to the park entrance, but Google Maps steered me right to the front gate where there’s a sign.

The gates were unlocked and open, so I pulled into the property and met with two of the park staff who were incredibly kind and accommodating. They were both familiar with the Parks On The Air (POTA) program which made it much easier for me to ask about spots where I could set up my station.

First, though, I wanted to know more about Mountain Island Educational State Forest so I asked ranger Laura about the history of the site.

Turns out, Mountain Island is the newest Educational State Forest in North Carolina and has been in the works for more than 20 years.

The Forest is a vast conservation area that protects 12 miles of shoreline on Mountain Island Lake in the Catawba River Basin. This lake is the primary drinking water supply area for Charlotte, Mecklenburg and Gaston Counties. She told me that one in 23 North Carolinians rely on this area for their source of water.

Much of the land was originally owned by Duke Power who put it up for sale in 1998. Conservation groups purchased the land from Duke’s real estate agency in 1998 and put it into a conservation easement. The land is actually in two counties (Gaston and Lincoln) and a portion in the city limits of Gastonia.

The NC Forest Service now manages the forest and supports the public-private partnership with the counties, municipalities, and conservation groups.

Mountain Island has been actively educating school groups and the public about the river basin and local flora/fauna for many years by appointment. Currently, a new education center is being built on the property and will soon be open to the public with regular business hours. Being so close to population centers, I imagine they’ll stay busy!

Shade

Park ranger Laura was kind enough to allow me to set up under a huge tree in front of their ranger station.

I was grateful for the shade: it was 92F (33.3C) and humid.

There were no picnic tables under the tree, but I happened to have two folding chairs in my car. I used one as a table and the other as a chair. I flipped over my GoRuck GR1 backpack to make a stable base for the Yaesu FT-817ND.

Gear list:

On The Air

I was super pleased to put the Yaesu FT-817ND back on the air. It’s been a while since I’d used it in the field because my review radios (TX-500, X5105, etc.) have taken priority.

I love the FT-817ND and believe it’s actually an exceptional transceiver for CW and SSB ops. The CW full break-in QSK is wonderful and I actually like the mechanical sound of the T/R relay switching (if you like pin diode switching, you should look the other way, though!). With the 500Hz CW filter installed, the front end is pretty bullet-proof, too!

This was the first time I had paired the FT-817ND with my 28.5 foot speaker wire antenna. The random wire antenna needs a good ATU to match impedance, so I employed the Elecraft T1 this time (soon I’ll also try the LDG Z-100A).

I had planned to do a little SSB work, but quickly realized I’d forgotten the FT-817ND microphone. A shame because this site actually has excellent mobile phone service so I could have spotted myself to the network. Next time–!

I started on 40 meters CW and worked ten stations in 21 minutes. That’s a perfect pace for me!

Next, I moved to 20 meters where I worked six more in 9 minutes.

I was incredibly pleased with how well the speaker wire antenna performed–especially on 20 meters.

From the Piedmont of North Carolina, I worked Montana, Texas, New Hampshire, and Italy with 5 watts into $4 worth of speaker wire.

I did a quick back-of-the-envelop calculation and discovered that I yielded about 943 miles per watt!

To be clear, IK4IDF did all of the heavy lifting in our contact with his 9 element Yagi, but still it’s awfully exciting to put DX in the logs with only fair propagation.

Video

Of course, I made a real-time, real-life video of the entire activation (save the set-up and take-down):

Onward and upward!

I packed up quickly because I had a SOTA activation planned that afternoon on Anderson Mountain. I’ll post a field report and video of that activation soon.

Rev 4 FT-817 Buddy Board

Also, I’m about to start soldering together G7UHN’s new Rev 4 FT-817 Buddy Board! Revision 2 worked wonderfully, but revision 4 now includes a CW memory keyer among other upgrades! (Woo hoo!)  All of the components are now in the shack–just a matter of soldering them together and programing the Arduino Nano. Andy, if you’re reading this, expect a call from me soon, OM!

Guest Post: Field Day – 200 QSOs with a Flashlight Battery

The PowerFilm LightSaver (Image: PowerFilm Solar)

Many thanks to Jim Cluett (W1PID) who has kindly allowed me to share this recent post from his website:


Field Day – 200 QSOs with a Flashlight Battery

June 2021

by Jim Cluett (W1PID)

Field Day was an experiment this year. I operated for nine hours using a 5V 18650 battery and made 200 QSOs before calling it quits.

I operated on the deck with an MTR 4-B designed by KD1JV. The antenna was an 88 foot doublet up about 45 feet. I used the ZM-2 tuner. For power I used the PowerFilm LightSaver. This is a 5 watt roll-up solar panel that charges a 3.7V 18650 battery rated at 3.2 Ahr. The battery inside the Powerfilm product is commonly used in flashlights. The combination of the rig and the power supply is crucial.

The MTR rigs will operate from 6 to 12 volts. The Powerfilm puts out 5V to a USB socket. The secret ingredient required to bring the USB voltage up to the operating voltage of the rig is a Baofeng USB charging dongle. This device takes a 5V input and outputs 10.3 volts… perfect for the MTR transceiver. With this voltage the MTR puts out a little less than 3 watts.

The PowerFilm LightSaver is designed to charge cell phones for hikers and campers. It weighs only about 5 oz. and rolls up into a tiny package. Any USB 5V cell phone charging battery could be used with the Baofeng dongle.

This year my whole station operated on 5V. I used a Samsung tablet for logging.

In New Hampshire it was cloudy for most of Field Day, but fortunately the amorphous solar panel provides some charging even when it’s cloudy. I’m guessing that after 9 hours of operating the battery was down to about half capacity. The beauty of this system is that one could operate indefinitely with moderate sunshine.

I’ve been experimenting with this setup during hikes and bike rides for the last couple of months with a view to using it for Field Day. This year’s emergency exercise proves that it is viable for an extended grid-down power outage.

What a brilliant challenge and test for Field Day, Jim! Thank you for allowing me to share it here on QRPer. Also, a hat tip to Eric (WD8RIF) for bringing this article to my attention!

Field Report: Let’s build a super simple antenna on-site and activate this park!

Until 2016, I had never purchased a commercial field antenna; I built all the ones I had ever used.

These days, I take a number of commercial antennas to the field and use them in my real-time videos and I really enjoy deploying and using them. My buddy Eric (WD8RIF) reminded me, though, that I hadn’t actually used a homebrew antenna in ages. He was right!

You see, while I believe commercial field antennas can be incredibly durable and compact, it’s important to note that antennas are one of the easiest components of an amateur radio system to build yourself. They require only the most simple of tools and are very affordable. And the best part? They can perform as well as those that are available commercially.

I also get a great deal of pleasure out of building things.

A simple goal

I’ve mentioned in previous posts that I often set a little goal that runs in the back of my mind for each park or summit activation I make.

On Monday, June 14, 2021, I made a simple goal: buy my antenna wire en route to Lake James State Park, build the antenna on site, and complete a valid Parks On The Air (POTA) activation.

A very simple antenna

I also decided to employ my Xiegu X5105 since 1.) it’s one of the most affordable general coverage QRP transceivers I own and 2.) it has a built-in antenna tuner (ATU).

One of the cool things about having an ATU is that, if it has the matching range, you can allow it to do the “heavy lifting” in terms of matching impedance.

Although I’d never put the X5105 to the test, I suspected its internal ATU would have the matching range to forgo building a 4:1 or 9:1 transformer and simply pair it directly with a random wire.

All I would need was a 28.5 foot length of wire for a radiator, at least a 17 foot length for a counterpoise, and a BNC to binding post adapter.

The antenna would benefit from multiple 17′ counterpoises, but I really wanted to keep this setup dead simple to prove that anyone can build an effective field antenna with a very minimum amount of components.

Even though I have plenty of wire lying around the house to build this simple antenna, I wanted to pretend I had none to prove that any wire would work.

And to add just a wee bit more challenge, I also limited myself to shopping for antenna wire between my home and the park without making a serious detour from my route. That really limited my options because there isn’t much in terms of commercial areas between me and Lake James State Park.

The wire

As I left the QTH, I decided that the best spot to shop was a Walmart in Marion, NC. It would only be a four minute round-trip detour at most.  I had a hunch that Walmart would even have speaker wire which would be ideal for this application.

In my head, I imagined I would have at least three or four choices in speaker wire (various gauges and lengths), but turns out I had a difficult time finding some at Walmart. We live in such a Bluetooth world, I suppose there isn’t much demand for it these days. A store associate helped me find the only speaker wire they had which was basically a 100 foot roll of the “premium” stuff for $17 US.

While I would like to have paid a fraction of that, in the end it’s not a bad price because once you separate the two conductors, you have double the amount of wire: 200 feet.

Although the frugal guy in me cringed, I bit the bullet and purchased their speaker wire. To be clear, though, I could have found another source of wire in that Walmart, but I preferred speaker wire for this application. And $17 to (hopefully!) prove a point? That’s a deal! 🙂

Lake James State Park (K-2739)

Once I arrived on site, I found a picnic site I’d used before with some tall trees around it.

I cut 28.5 feet of the speaker wire and split the paired wires so that I’d have two full 28.5 foot lengths.

Next, I stripped the ends of the wire and attached banana jacks I found in my junk drawer. Although these aren’t necessary as the binding post adapter can pair directly with the wire, I though it might make for a cleaner install. In the end, though, I wasn’t pleased with the connection to the radiator, so dispensed with one of the banana jacks.

Next, I deployed the 28.5 radiator with my arborist throw line, and laid the other 28.5 half on the ground (the ground of this antenna would pair with the black binding post, the radiator with the red post).  I only needed 17 feet of counterpoise, but once it couples with the ground, I don’t think any extra length makes a difference (although less than 17 feet likely would).

The antenna was essentially set up as a vertical random wire with one counterpoise.

My new speaker wire antenna in all its glory.

Gear:

On The Air

I’ll admit: I was a bit nervous putting this antenna on the air. Although I felt the X5105 ATU *should* match this antenna, I had no idea if it actually would.

Fortunately? It did.

At this point, if you don’t want any spoilers, I suggest you watch my real-time, real-life, no-edit, no-ad, video of the entire activation (including buying and building the antenna!).

Click here to watch the video.

Otherwise, scroll for my activation summary…

I was very pleased that the X5105 found a match on the 40 meter band.

I started calling CQ in CW and validated my activation by logging 10 stations in 13 minutes.

Honestly: it doesn’t get much better than this.

I logged three more stations on 40 meters CW, then moved up to the 30 meter band where the X5105 easily found a match.

I worked one station on 30 meters before heading back down to the 40 meter band to do a little SSB. I logged three SSB stations in five minutes.

Mission accomplished!

In the end, I logged a total of 17 stations including a P2P with K4NYM.

Not bad at all for speaker wire!

After the activation, I tested the X5105 ATU by trying to find matches on other bands–I was able to find great matches from 60 meters to 6 meters. Most impressive!

X5105 battery

You might recall that I attempted to deplete my X5105 internal battery at my last (rather long) activation of Lake Norman State Park.  I wasn’t able to deplete the battery at that activation, but I finally did at this one.

All I can say is that I’m incredibly impressed with the X5105 internal battery.  This was my fourth activation from one initial charge on May 16.  The battery lasted for 20 minutes, taking me well beyond the 10 contacts needed to validate this park. I’ll now consider taking the X5105 on a multiple SOTA summit run!

Short Hike

Even thought the heat was intense and the humidity even more intense, I decided to take in a 2 mile hike post-activation. I snapped a few shots along the way.

This is the Christmas Fern which derives its name from a few characteristics: its resilience to early season snows maintaining a dark green color beyond Christmas, and because folks believe its leaves are shaped like Santa’s boots or even Santa on his sleigh.

Improvements

I’ll plan to add more counterpoises to the speaker wire antenna as I know this will only help efficiency.

In addition, I’ll plan to build even more antennas with this roll of speaker wire. If you have some suggestions, feel free to comment!

Thank you for reading this field report!

Cheers,

POTA Field Report: Attempting to deplete the Xiegu X5105 internal battery at Lake Norman

Each time I head to a park or summit, I have a goal in mind.

With summits, it’s getting to the summit and activating it because, sometimes, that can be a challenge in and of itself. I’m not exactly Sir Edmund Hillary, so I’m happy when I make it to the top of any summit!

Parks, however, offer me the chance to experiment with transceiver/antenna combos, test gear, and explore hikes. Parks tend to be more accessible and spacious than summits and even have shelter options if weather is questionable.

I don’t even attempt afternoon summit activations if they require a decent hike and there’s a good chance of pop-up thunder storms.

On Monday, June 7, 2021, it was hot and incredibly humid in the Piedmont of North Carolina. That early afternoon, little patches of showers were passing through the region delivering brief, isolated downpours.

The weather forecast also predicted a high likelihood of thunderstorms that afternoon. (Turns out, they were correct.)

Those were not conditions for a SOTA activation, rather, I decided to pick out a park I knew could offer up some shelter options. Lake Norman was an obvious choice–there’s a very nice covered area at their visitor’s center and also two large picnic shelters at the other side of the park. Lake Norman it was!

Goal

I drove to Lake Norman State Park with one goal in mind: deplete the Xiegu X5105 internal battery. I had assumed the battery would only power the X5105 for perhaps two activations on one charge.

Boy, was I wrong.

I charged the X5105 before this activation on May 17, then I completed this short activation on May 18. I never expected the battery to keep going, but it did.

Now three full weeks later, I decided I would deplete the battery at Lake Norman because that afternoon I had a decent amount of time to play radio in the field. In my head, I was prepared to squeeze perhaps 30-45 minutes more air time out of that one May 16 battery charge.

Lake Norman (K-2740)

I arrived at Lake Norman State Park and scouted out a site. Fortunately–it being a Monday in the early afternoon–it wasn’t busy and all three shelters were available.

I chose to set up at a shelter at the far end of the main picnic area.

Gear:

The humidity was so thick that day,  I was sweating just walking around the site. I noticed in my activation video (see below), I was breathing as hard as I would hiking to a summit even though I was just tooling around the picnic shelter.

I had no doubt in my mind that if a thunderstorm developed, it would be a doozie! (I was right about that, too–keep reading.)

On The Air

I paired the Xiegu X5105 with my Chameleon MPAS 2.0 mainly because I wanted to see how easily the X5105 ATU could match this multi-band vertical. Turns out? Quite easily.

I expected the X5105’s battery to deplete to the point that I would need to use an external power source to complete the activation, so I connected my QRP Ranger battery pack, but didn’t turn it on. I knew that when the radio died, I could flip the QRP Ranger’s power switch and perhaps only lose a few seconds of air time.

I hopped on the air and started calling CQ. I planned to operate the X5105 until the internal battery died, then (if needed) continue operating with the QRP Ranger until I logged my 10 contacts for a valid activation. Post activation, I planned to hike one of the Lake Norman loop trails.

Normally, I would mention the number of contacts I made perhaps noting the bands that were most productive. Instead, if you’d like to experience this activation with me, you might consider watching the activation video.

Video

Here’s my real-time, real-life, no edit video of the entire activation including my full set up.  My summary of the activation follows–keep scrolling if you’re open to a spoiler.

Please note that this is the longest video I’ve ever published, so don’t feel any pressure to watch it in its entiretity:

Impressed

Let’s just say that the X5105 sold me.

The activation was incredibly fun and I logged 20 stations (18 CW and 2 phone) from Alaska to Spain with my 5 watts and the MPAS 2.0 vertical.  Propagation conditions were only “meh” but since I had the time to play radio longer, I was able to take advantages of little openings as they happened.

X5105 Battery

The X5105 won.

I simply gave up on trying to deplete the internal battery because I was running out of time to fit the activation and a much needed hike that afternoon before thunderstorms moved in.

I operated over 90 minutes with constant CQ calls and the battery never made it below 10.2 volts.

A most welcome surprise.

No mic, no problem!

During the activation, I remembered that I had been asked by readers and viewers to include more SSB work.

Problem was, I left my X5105 mic at the QTH (nearly 2 hours away by car).

I remembered though that, like the Elecraft KX2, the X5105 has a built-in microphone.

I decided to give that mic a trial by fire and, by golly, it worked!

Not only did it work, but it worked well.

The X5105? A keeper.

It was at Lake Norman that day, I decided the X5105 was a keeper.

That evening, I reached out to Radioddity–who lent this X5105 to me–and offered to pay full retail price for it either in cash or via ad credit

Since Radioddity is a sponsor on my other radio site–the SWLing Post–we decided that, since their ad was coming up for renewal soon, I would simply extend their ad time an equivalent amount of months as the full value of the X5105 ($550 US). This saved them from having to cut a check in two months.  Worked for both of us.

I have much, much more to say about the X5105 and will do so in an upcoming review.

In short, though? It’s not a perfect radio by any means, but I feel like it really hits a sweet spot for the QRP field operator.

I enjoy putting it on the air and it’s an incredibly capable little transceiver.

I’m very pleased to now put it in rotation with my other field radios. Look for it in future reports!

QSO Map

Here’s the QSO Map for this activation (click to enlarge):

Hike and dodgy weather

After packing up my gear, I walked over to a nearby trailhead and checked out the trail map. I was prepared to take a very long hike that afternoon despite the heat and humidity, but I also knew conditions were ripe for a thunderstorm.

I decided to take what appeared to be a fairly short loop trail along the lake. Looking at the map, I assumed the trail might be 1 mile or so long.

The hike is well-worn and well-marked, so there’s no getting lost here. That’s one of the reasons I didn’t bother looking at my GPS map or even consulting the trailhead map in detail.

Instead, I simply started hiking the Lake Shore Trail loop. It was gorgeous. Here are a few photos (click to enlarge):

The skies started getting dark, though, and I heard a little distant thunder.

I decided it might make sense to consult my phone for the weather map.

A line of thunderstorms had developed and they were sweeping toward me. Time to pick up the pace of hiking!

It was at this point I realized I had underestimated the length of this loop trail. Part of me was quite pleased that it was longer than I anticipated, but the part of me that didn’t want to be caught out in a t-storm wanted to get back to the car ASAP.

I checked another weather map a few minutes later.

I decided that jogging the rest of the trail made sense!

Turns out the 1 mile loop was something closer to 3 miles when I included the walk back to the car.

I did make it back to the car in time, though, right before the heavens opened.

It’s no exaggeration to say that I was sincerely concerned about the possibility of tornadoes in that storm front.

The skies were dark enough that streetlights turned on and the rain was incredibly heavy with strong wind gusts. I saw flash flooding and driving conditions were nearly impossible. I parked next to a brick building in the town of Catawba and waited for the strongest part of the storm to pass. I was also very grateful I wasn’t still on the trail by the lake!

Of course, the storm passed and I expected conditions to be a little drier behind that front, but I was wrong. I think the humidity level increased to 150%. Ha ha! No worries, though, as I was on my way to air conditioned space!

Thanks so much for reading this field report and stay safe out there!

73,

Thomas (K4SWL)

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

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:

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!

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

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:

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,

The new Xiegu X6100 portable HF transceiver: Yes, it’s real and no it’s not vaporware

It seems folks are now finding out about the new Xiegu X6100 HF & 6 meter portable transceiver.

There have been a few rumors about it, so I thought I’d share some of the few details that have been confirmed.

What is the X6100?

If the Xiegu X5105 and Xiegu GSOC had a baby, it would look like the X6100.

The X6100 is a completely self-contained SDR QRP transceiver much like the X5105. The X6100 sports a 4″ high-resolution color capacitive touch screen and is built on on a quad-core processor, 4G ROM, and 512MB RAM. I assume this will run on a similar Linux version/distro as the GSOC.

The X6100 will include an internal automatic antenna tuner (ATU) and a 3500 mAh internal rechargeable Lithium Ion battery pack.

Power output will be 5 watts when using the internal battery pack and 10 watts when connected to an external power source.

Key features:

  • Modes: USB/LSB (J3E), CW (A1A), FM (F3E), RTTY (F1B), AM (A3E)
  • Receiving: 0.5MHz~30MHz, 50MHz~54MHz
  • Transmitting: 1.8~2.0MHz, 3.5~3.9MHz
    5.3515~5.3665MHz 7.0~7.2MHz 10.1~10.15MHz 14.0~14.35MHz 18.068~18.168MHz 21.0~21.45MHz 24.89~24.99MHz 28.0~29.7MHz 50~54MHz
  • External voltage range : 9.0~15.0VDC
  • Integrated SWR meter
  • Voice and CW memory keying
  • Integrated modem
  • Native Bluetooth and WiFi functionality (easy keyboard and mouse connectivity)
  • Two USB interfaces supporting HOST and DEVICE
  • Standard high stability TCXO
  • 24bit sampling rate and “large dynamic RF front-end unit”
  • Ruggedized chassis and backlit buttons
  • Maximum current consumption in receive: 550mA

Early Product Sheet

I’ve also been sent a pre-production product brochure. This has a number of details and, as you’ll see, it even hasn’t been through a final edit.

Click here to download the preliminary Xiegu X6100 product brochure (PDF).

Pricing and availability

Pricing and availability have not been determined at time of posting. I will post an update when that information can be confirmed.

I can only assume bringing this new radio to fruition will take time. Most radio manufacturers are struggling to keep up inventory levels as we work our way out of the C-19 pandemic supply chain issues. Parts availability has become a real issue.
