Activating Elk Knob State Park for SOTA, POTA, and WWFF

6 Comments

On Monday, March 8, 2021, I had a very rare opportunity: nearly a full day to play radio!

I debated where to go the night before and I had a lot of ideas. Do a multi-park run?  Activate some new-to-me parks a little further afield? Hit a SOTA summit?

While it was very appealing to plan a multi-park run for POTA/WWFF, I really wanted to stretch my legs and activate a summit. The weather was glorious and it dawned upon me that we’ll soon be entering the season of afternoon thunderstorms which will, no doubt, have a negative impact on my summit plans for the next few months since afternoons are typically when I have time to do activations.

After examining the map, I decided to go to Elk Knob State Park. The summit of Elk Knob is a SOTA site and the park is in both the POTA and WWFF programs.

Last year, I activated Elk Knob State Park and really enjoyed the experience.

The round trip hike to the summit (adding in a little trail loop around the park) would amount to about 4 total miles and an elevation increase of roughly 1,000 feet.

Monday morning, I left the QTH around 9:00 and arrived at the park around 11:15–it was a proper scenic drive.

The 1.9 mile hike to the summit took me about 45 minutes. The path was amazingly well maintained: 4′ wide with crushed stone most of the way.

One of the nicest trails I’ve been on in ages–Elk Knob State Park is quickly becoming one of my favorite NC State Parks.

There aren’t any antenna-friendly trees on the summit, so I was happy that I packed the Chameleon MPAS 2.0.

At first, I planned to only bring the top section of the MPAS 2.0 vertical to save space, but the hike was so short, I brought the lower aluminum sections as well. I’m glad I did.

Deployment of the MPAS 2.0 was quick and I the Elecraft KX2‘s internal ATU found a match on 20 meters very quickly.

Elk Knob (W4C/EM-005)

I spotted myself using the SOTA Goat app and received quite a 20 meter CW pileup! As you’ll see in my video below, it was testing the limits of my CW skills for sure.

With 5 watts, I quickly worked stations to my east in France, Spain, and Germany, and to my west all over the west coast of North America. It was a hoot!

I eventually moved to 40 meters and operated a bit, but 40 was suffering from poor propagation so stations that are normally quite strong, were weak that day.

I needed four stations for a valid SOTA activation and 10 stations for a valid park activation. I logged a total of 38 stations in 56 minutes. 75% of those contacts were on 20 meters.

Video

Here’s one of my real-time, real-life videos of the entire activation (less a small amount I removed while eating a quick bite):

When people tell me running QRP is like “trying to play radio with both hands tied behind your back” I’ll show them this video. 🙂

AGN?

While the hike, the weather, and the signals were all in my favor, I’ll admit I wasn’t on my “A Game” that day. We all have days like this where we struggle to copy, to keep up with the flow of contacts, and to send correctly.

In recent weeks, I’ve gotten a number of emails from readers and viewers who said they had a less-than-smooth SOTA or POTA activation and felt a wee bit embarrassed on the air when they struggled copying.

But you know what?

No worries!!!

This is all about having radio fun in the field, enjoying a hike, taking in the views, and soaking up the beautiful weather! It’s not a contest and we have nothing to prove to anyone.

I can also promise you that any chaser/hunter who has ever activated a field site will completely understand if they have to send their call a couple extra times or if they (heaven forbid!) have to re-send their call after you incorrectly copy a character.

This is totally normal.

Be easy on yourself and enjoy the ride. Even on days when I don’t feel like I’m 100% in the groove, I find doing a summit or park activation clears my mind and resets my soul.

My policy? When a mistake is made laugh it off and move on!

SOTA Field Report from Rocky Face (W4C/WP-006)

5 Comments

One of the things I love about POTA and now SOTA is that it gives me a reason to venture out and explore parks and other public lands that might have otherwise never shown up on my RADAR.

Rocky Face is a prime example.

On the morning of Wednesday, March 10, 2021, I would have never guessed that by noon I would be standing on the summit of Rocky Face. That morning, I had planned to activate the summit of Baker’s Mountain–a park and summit I know very well as I’ve hike the trails there almost monthly and the mountain is a stone’s throw from my parents’ home.

That morning, when I arrived at Baker’s Mountain Park and the gates were shut, I remembered that they are closed on Wednesdays.

Oops.

I was determined to hike to a summit, though, so I grabbed my iPhone and launched the SOTA Goat app, then searched for nearby summits.  That’s when I noticed Rocky Face which was *only* a 40 minute drive from Baker’s Mountain. I had heard of this 1 point summit and park, but had never been there, so why not take a little road trip and explore?

Rock Face (W4C/WP-006)

View of Rocky Face from the road.

It was a very pleasant drive which was made all the better by gorgeous sunny weather.

When I arrived on site, I was surprised to see just how well developed this park was. There were two different parking areas, a visitor’s center, picnic area, rock climbing face, playground, and numerous trails. There’s even a large area for outdoor events.

I took the “Vertical Mile Challenge” to the summit (which I would recommend) and was more of a workout that one might imagine for a 1 point 576 meter summit.

The trail was very well maintained. The ascent up the granite slope offered some welcome views of the surrounding area.

I was a little surprised to find some Nodding Trilliums blooming on the side of, and even on the path. A sure sign spring is on the way!

March 10th was also one of the warmest days of the year so far.

On the summit, there were actually a couple of picnic tables–a total surprise which made this SOTA operation feel somewhat luxurious!

On The Air

I set up the Elecraft KX2 and Chameleon MPAS 2.0 which were still packed from a SOTA activation two days earlier at Elk Knob (I’ll post a report of that activation in the near future).

I had not charged the Lithium Ion pack in the KX2 after the Elk Knob activation, but I assumed I’d still have enough “juice” to get me through the Rocky Face activation at 5 watts.

I started by calling CQ SOTA on 20 meters. A friend told me that propagation was very unstable, so I feared the worst. Fortunately, 20 meters was kicking (40 meters much less so).

Right off the bat, I worked stations in France, Germany, Slovenia, Quebec, Spain, and all of the west coast states of the US. It was so much fun and exactly why I love QRP and playing radio in the field.

As I switched from 20 meters to 40 meters, some hikers passed by. Turns out it was my cousin and her husband–what a surprise! Of course, they had no idea what I was up to, so I ended up explaining not only SOTA, but amateur radio and why I was using CW (yeah, I cut that bit from the activation video below).

They moved on and I hit 40 meters which was hit harder by the poor propagation. Many stations I regularly work were a good 2-3 S units lower in signal strength.

I am certainly looking forward to some stable propagation eventually! Still…very, very pleased with the 24 stations I worked and the QRP DX as well.

Here’s a QSOmap of my contacts–all from 5 watts and a vertical:

Rocky Face turned out to be a fun little hike, productive activation, and a great opportunity to explore a new summit and park. I’ll certainly return!

POTA Field Report: “Wham Bam!” Blue Ridge Parkway activation

8 Comments

Last Tuesday (March 2, 2021), I needed to make a quick trip to south Asheville and pick up some gear I had ordered from REI.  Of course, I had a hankering to fit in a Parks On The Air activation. I contacted my buddies Eric (WD8RIF) and Mike (K8RAT) and mentioned I might make a visit to the Blue Ridge Parkway [it’s always a good idea to have others look for you in case your unable to spot yourself on the bands].

By the time I jumped in the car, though, I talked myself out of doing the activation.  Propagation was poor and I had a maximum of 30 minutes to fit in a valid activation.

After picking up my gear at REI, I realized, though, that a 30 minute limit made for an awfully fun challenge.

I had to pass by the parkway to go home, so why not? Right?

I did a quick check and, yes(!) I had the Elecraft KX2 and CHA MPAS Lite antenna in the car.

Before leaving REI, I scheduled my activation on the POTA website so that the site would know to auto-spot me if the Reverse Beacon Network picked me up.

Blue Ridge Parkway (K-3378)

I arrived at the parkway in very short order. I decided to do the activation at the Blue Ridge Parkway Visitor’s Center and Headquarters. Normally, I avoid this location because it’s busy and the best spots to set up a radio are in the path of visitors walking around the perimeter of the grounds.

It was a cold, overcast Tuesday morning so, as I expected, I almost had the place to myself.

Gear:

I deployed the CHA MPAS Lite vertical in very short order–perhaps 3 minutes. Since I had also packed my Pixel 3 camera/phone and tripod in the car, I even recorded a video of the full activation (see below).

In short? I snagged my 10 contacts in about 19 minutes on the air–all on 40 meters CW. Not too bad for a Tuesday morning with five watts and a vertical.

Here’s a QSOmap of the contacts I made:

I also had a first at this activation! I worked ND9M/MM. To my knowledge, I’ve never worked a maritime mobile station at a park activation–certainly not in CW! The map above omits this contact since the location was unknown.

When I submitted my log to Bill DeLoach (our regional contact for POTA logs) said I really need a “Wham Bam!” award for this quick activation. Ha ha!

Here’s a real-time, real-life video of the entire activation:

SOTA Field Report: Activating Lane Pinnacle with the Elecraft KX2 and CHA MPAS Lite

5 Comments

I’ll let you in on a little secret. Don’t tell anyone, but I held off making my first Summits On The Air (SOTA) activation  until the stars aligned and I could activate one particular summit completely on foot from my QTH.

Last Thursday (February 25, 2021), my daughter and I hiked to Lane Pinnacle (W4C/CM-018) and performed my first Summits On The Air (SOTA) activation.

Why did I wait so long?

We live in the mountains of western North Carolina where (obviously) there are numerous SOTA summits to activate.

But I wanted Lane Pinnacle to be the first.

Why? Well, it’s the one summit I can hike to directly from my house with my daughter Geneva (K4TLI) and enjoy a proper father/daughter day hike.

I had planned to do this hike last year, but I injured my ankle and let’s just say that the hike to Pinnacle isn’t a beginner’s run.  I knew my ankle would need to properly heal before the journey.

This is also more of a late fall to very early spring hike due to the amount of thick foliage we knew we would have to mitigate. It’s so much easier to keep your bearings when there are no leaves on the trees nor on the green briar!

Last Thursday, I felt confident that my ankle was up to the task. We had a break in the weather as well with moderate temps and lots of sunshine (this, after several days of rain). We knew things could be muddy and slippery, but we also knew that with my busy schedule this might be our last chance to hit the summit before the mountains green up.

So we packed a lunch, plenty of water, radio gear, and (of course) emergency/first-aid kits while trying to keep our backpacks as light as possible.

Hitting the trail!

The first part of the hike requires trailblazing to a ridge line. The distance is short, but the ascent is steep (about 800 feet).  We hike this portion regularly, so knew how to pick our path and avoid the steeper, slippery bits.

K4TLI lead the way!

On the ridge line, we intersected an established single track trail and enjoyed the hike across a couple of smaller summits until we intersected the Blue Ridge Parkway.

If I’m being honest, I had some serious concerns that the trailhead to Lane Pinnacle would be closed. This portion of Blue Ridge Parkway is currently closed to motor vehicles (for the winter season) and I had noticed a number of “trail closed” signs on other portions of the parkway.

Guessing this may be a type of shelf fungus?

If the trail was closed, I planned to simply activate the parkway and Pisgah National Forest for the POTA program. I never hike on trails that have been closed by the park service because I like to obey the rules and I certainly don’t want to paint SOTA activators in a bad light.

When we crossed the parkway, we were incredibly pleased to see that the trailhead was open.

The ascent from the parkway to Lane Pinnacle is about 1,000 feet (305 meters) of elevation gain over a pretty short distance. The trail we were taking–turns out–was primitive. It basically lead us straight up the slope (no switch backs following lines of elevation, for example) and simply fizzled out about one third of the way up.  We could tell it isn’t traveled often at all (although we did find a massive fresh bear track in the mud on the trail!).

Obligatory SOTA report “foot in snow” photo. 🙂

I bushwhacked our way to the top–at times, the slope was about 45 degrees and slippery, but we easily found our way to the summit where our goat path intersected the Mountains To Sea trail.

We found an amazing overlook and took in views of the Bee Tree Reservoir as we ate our lunches.

Geneva grabbed her dual-band HT and made the first summit contact with our friend, Vlado (N3CZ) on 2 meters FM.

On the Air

I knew there would be short trees on the summit of Lane Pinnacle, but I also knew that I wanted to get on the air as soon as possible to allow extra time for our hike home.

I did pack a super compact wire antenna, but opted instead for the Chameleon CHA MPAS Lite vertical. I paired it with my Elecraft KX2.

Gear:

The great thing about the CHA MPAS Lite is how quick it is to deploy–it might have taken me all of three minutes.

Since it was noon, I decided to start on the 20 meter band. I found a clear frequency, started calling “CQ SOTA” with the KX2 memory keyer, and spotted myself to the SOTA network via the excellent SOTA Goat app on my phone.

I had also scheduled my activation on the POTA website in advance because Lane Pinnacle is in Pisgah National Forest (K-4510). My buddies Mike (K8RAT) and Eric (WD8RIF) were also helping to spot me in the unlikely event I wouldn’t have cell phone service on the summit.

Within 20 seconds of submitting the spot to the SOTA network I had a CW pileup.

In all of my hundreds of field activations, I can’t think of a single time that I generated a CW pileup on 20 meters in such short order with five watts and a vertical.

The first station I logged was N1AIA in Maine. The second station was F4WBN in France.  The race was on!

It took every bit of CW skill I had to pull apart the stations on 20 meters. It was so much fun!

I eventually worked Spain and all of the west coast states (WA, OR, and CA) and numerous stations throughout the Rockies and Midwest.

I then moved to 40 meters where I worked stations in the Mid-Atlantic, Ohio Valley, and in the Southeast.

In the end, I had to keep my total time on the air short because I wanted to take my time finding a path from the summit back down to the Blue Ridge Parkway.

In 30 minutes I worked 30 stations. I’m not a seasoned CW operator, so this was quite the accomplishment.

Here’s a QSOmap of my contacts:

I was chuffed! What a fabulous activation to kick off my SOTA adventures.

Video

This time, I did not make a video of the actual activation. For one thing, I didn’t want to carry a folding tripod for the camera and I didn’t want to ask my daughter to film it either. I wanted to keep things as simple as possible to make the most of the airtime I had.

I did, however, make a short video before and after. You can check it out on my YouTube channel:

Hiking home

I really wish we could have stayed on the summit for an hour longer making contacts, but I knew it would be wise to allow extra time to descend Lane Pinnacle especially since I knew a front was moving through later that day.

I decided it would be easier to do my own bushwhacking back down the mountain rather than try to retrace our previous steps. We took our time and I followed elevation lines to make it slightly less steep. Since I took a more south westerly descent, when we reached the parkway, we had to hike north to reach the original trailhead.

The rest of the hike was totally uneventful and incredibly fun. The weather held and we took in the views, the wildlife, and invaluable father/daughter time.

That was the first strenuous hike I had done in months due to my ankle, so let’s just say I was feeling “spent” after our 6.5 hour adventure taking in 2,000 feet (610 meters) of elevation to the summit.

I knew it was bad when I even dreaded walking upstairs to take a shower.  I think I remember telling my wife, “I’m never building a house with stairs again!”

More SOTA!

Now  that I’ve got Lane Pinnacle in the books, I’m ready to start hitting the summits! I’ve got a lot of pent up SOTA energy!

My goal is to activate a total of ten this year. That may sound like a modest number, but since at this point I’m less interested in “drive-up” summits, it’s more difficult to fit SOTA summits into my schedule than, say, typical POTA/WWFF parks.

In fact, I’ve already plotted my next SOTA activation and hope to do it within the next couple of weeks. It’s also a meaningful (to me) summit.

How about you?

Are you a SOTA activator or are you planning your first SOTA activation soon? Please comment!

POTA Field Report: Pairing the Icom IC-705 with the CHA MPAS Lite at Tuttle

10 Comments

Last week, we had a glorious break in the weather–it felt almost spring-like.

On my way back home after visiting my parents, I decided I would take in a quick afternoon hike. I originally planned to go to one of my favorite county parks, but I also had a hankering to get on the air and that park wasn’t a part of the POTA network.

Tuttle Educational State Forest (K-4861)

I decided to stop by Tuttle Educational State Forest (K-4861) instead and make February 19, 2021 not only a hiking day, but a Parks On The Air day. Tuttle sports both excellent sites for POTA and a nice little trail system.

Gear:

I decided to play radio first then go on a hike, so I pulled out an antenna that I thought would give me quick deployment and pack-up: the CHA MPAS Lite.

I also remembered that a reader recently asked if I would include the deployment of the CHA MPAS Lite in one of my real-time, real-life activation videos. So I did just that!

Deployment was quick and the mAT-705 Plus ATU did a fine job finding matches on the CHA MPAS Lite.

I started calling CQ on 40 meters and worked quite a few stations in short order. When the first batch of eight chasers was worked, I moved up to the 20 meter band and started calling CQ. My hope was that I could work at least a couple of stations on 20 meters then pack up and go for a hike.

I started calling CQ on 20 meters and was quickly rewarded six additional contacts.

Without a doubt–if this wasn’t completely obvious in my video–the highlight was working my friend John Harper (AE5X) in Texas. I’ve known John for years now and have followed his excellent blog but we’ve never managed to catch each other on the air!

Turns out, John was using his recently unboxed Icom IC-705 as well. Click here to check out his post which includes a mention of this very activation. In addition, check out his thoughts after taking the IC-705 (all amped-up with the KPA-500) on the ARRL CW contest that weekend.

Another highlight was logging CU3BL in the Azores again. To me, it’s still mind blowing that 5 watts can reach out that far.  Here’s a QSOmap of the activation (click to enlarge):

In total, I logged 14 stations with 5 watts and a vertical in very short order, leaving me a full hour of hiking time! Mission accomplished!

Video

Here’s a real-time, real-life video of the entire activation:

The hike afterwards was just what the doctor ordered, too. I’ve mentioned before that my ankle has been healing nicely after twisting it badly in December. This hike was an easy one and gave me a chance to properly test my ankle before the (epic-to-me) SOTA activation I planned with my daughter, K4TLI the following week. (More on that in a future post!)

Here are a few photos from the Tuttle hike:

If you ever find yourself at Tuttle Educational State Forest doing a POTA activation, make time to take in a hike as well. It’s a gentle hike and even the long loop can be completed within an hour at a very leisurely pace.

Thanks for reading this field report and please comment with your experiences on the air and in the great outdoors!

Pairing the MFJ-1984LP EFHW with the Elecraft KX2 at South Mountains Game Land

1 Comment

Last week, I squeezed in two activations on the afternoon of February 17, 2021 to test out the MFJ-1984LP end fed half wave antenna that MFJ sent me to evaluate.

The first park was Lake James State Park where I paired the MFJ-1984LP with my Icom IC-705 (click here to read the report and watch the video). The second was South Mountains Game Land where I paired it with the Elecraft KX2.

Gear:

In both instances, I did not use an ATU because the EFHW is resonant on the bands where I operated. I bypassed the internal ATU in my KX2 and, of course, the IC-705 has no ATU.

I’ve got a very busy few days ahead including a presentation tomorrow at the Virtual Winter SWL Fest (the topic being QRP transceivers). In lieu of writing a full field report, I’ll simply share the (partial) video I made at the activation.

I’ll admit it, I was not on my “A Game” at that activation. Not only did I forgot to press the start button on the camera, but I also struggled copying CW more than I usually do. I had a lot on my mind that afternoon, though, and really felt pressed for time.

I don’t mind sharing this experience, however, because we all have days like these.

POTA Field Report: Reviewing the MFJ-1984LP EFHF with the Icom IC-705 at Lake James State Park

7 Comments

I’ve been a ham radio operator since 1997, but until 2016, I had never purchased a pre-made portable antenna–I had always built my own.

During the 2016 NPOTA (National Parks On The Air) program, however, I purchased the EFT Trail-Friendly end fed 40, 20, and 10 meter resonant antenna and it quickly became my favorite field antenna. I found that it was simply built better than I could have built a similar antenna at home.

Pre-made antennas, though, come at a cost. Most time-tested, trail-friendly, portable antennas will typically set you back $90 US or more. You can make similar antennas much cheaper especially if you already have some of the parts (wire, toroids, RF ports, enclosures, etc).

Recently, while browsing the MFJ catalog, I stumbled upon the MFJ-1984LP End Fed Half Wave wire antenna designed for for field use and retailing for only $49.95 US.

That price point is very attractive because I believe if I built this antenna myself and needed to buy new parts, I might easily sink $20-25 in it.

Most MFJ products are manufactured in the USA and the company has an incredibly extensive and diverse selection of items in their catalog. Why I had forgotten they also sell antennas is a mystery to me.

MFJ is well-known for offering products that are basic,  affordable, and accessible (they’re available directly from the manufacturer and through most major radio retailers across the globe). I wouldn’t expect their antennas to be engineered like Chameleon Antenna, for example, but I would expect them to work well and get the job done.

I know the folks at MFJ and (in the spirit of full disclosure) they even sponsor QRPer.com, so I reached out to them and asked if I could evaluate their MFF-1984LP which is their most affordable field wire antenna.  They kindly sent one my way and I took it to the field last week.

I should add here that MFJ welcomes critical reviews, which is one of the reasons I asked them to be a sponsor. That and, well before they knew me, I was an anonymous customer and they repaired my MFJ roller inductor tuner for free a good two or three years after the warranty expired. My experience with MFJ has only been positive.

First impressions

The antenna looks exactly like the product photo in their catalog (see above).

For a field antenna, the coil enclosure is a little on the large side (especially compared with my EFT Trail-Friendly), but it’s still very backpack-able. Knowing MFJ, they kept costs at bay by using one of their standard enclosure boxes for this antenna.

The enclosure also has an open grill to allow the coil to dissipate heat (see above). I found that a bit surprising since the core is so large inside, but I assume some heat must be generated if you’re running 50% duty at a full 30 watts (the maximum rated power). The matching network impedance ratio is 49:1, so there will be loss and heat.

The 66 foot radiator wire has a dark jacket that glides nicely over tree limbs and doesn’t encourage tangling when unwinding.

The end insulator is made of a thin plastic/composite material that is lightweight and shaped so that it won’t snag on tree limbs.

To the field!

Hey–the proof is in the pudding, right? Let’s put this antenna on the air and make a real-time video of the activation!

Last Wednesday (February 17, 2021), there was a break in the weather so I made a detour to Lake James State Park (K-2739) en route to visit my parents for a few days. I left the house without deciding what park to activate, but picked Lake James because I knew I would have access to tall trees and my pick of operating locations.

Gear:

Deploying the MFJ-1984LP is no different than deploying any other wire antenna. It was super easy using my arborist throw line. That thin, rounded end insulator did certainly glide through the tree branches with ease. No hint of snagging.

On The Air

I connected the antenna directly to my IC-705 with no ATU in-line. Hypothetically, I knew this antenna should be resonant on 20 meters where I planned to start the activation.

Keep in mind that pre-made antennas are often designed to be a tad long and need to be trimmed so the operator can tweak the resonant point for their preferred spots on the band. Since I tend to use the lower part of the band for CW, I typically leave my antennas with a resonant point somewhere on the upper side of the CW portion of the bands. It’s not super critical for EFHW antennas because they tend to have ample bandwidth to give a full meter band good matches.

I had not trimmed the MFJ-1984LP, but decided it should be “resonant enough” for my purposes.

I found a clear frequency on 20 meters and checked the SWR. It was spot on at 1.3:1 on 14,031 kHz! Woo hoo!

I started calling CQ and collected several stations in short order despite the poor propagation that day.

I then moved to the 40 meter band and discovered the antenna also gave me an excellent match there. I started calling CQ POTA and was rewarded with a steady stream of contacts.

I imagine I could have racked up a lot of contacts at that activation, but I made up my mind that I wanted to fit in another quick activation afterwards, so cut it a bit short.

In the end, here’s a map of my 18 contacts made in 26 minutes of on-air time:

Not bad for five watts and a wire!

Video

I made a real-time, real-life, no edit video of this activation which starts shortly after I deployed the MFJ-1984LP and ends a few moments after my last QSO. Against my better judgement, it includes all of my mistakes (including my inability to form the number 4 that day!):

MFJ-1984LP summary

No antenna is perfect and each time I start a product review, I keep a list of pros and cons. Here’s my list for this EFHW antenna:

Pros:

  • Very affordable at $49.95
  • Effective: results so far have been excellent
  • EFHW is a proven field antenna design and resonant on several bands
  • No coil on the radiator to snag in trees (see con)
  • Backed by MFJ warranty
  • Purchase supports US manufacturing

Cons:

  • Bulkier than comparable low power field antennas
  • No built-in winder (MFJ should consider altering the design to include one!)
  • Radiator is 66 feet long since there is no in-line coil to electrically shorten the length (see pro)
  • End insulator is effective, but feels slightly flimsy

In the end, there’s no magic here: the end fed half wave is a time-tested, proven antenna design and the MFJ-1984LP delivers. In terms of performance, I couldn’t be more pleased with it right out of the box. This isn’t a military-grade antenna, but it should last for years with proper use.

POTA activators that have access to trees in the field will appreciate the MFJ-1984LP. I should think you could also make an effective “V” shaped antenna if you have a telescoping support that’s 29-33′ tall.

I’m not so sure the average SOTA operator would find this antenna design as convenient–especially on high summits where you’re near or above the tree line. It could be difficult deploying a 66′ wire. That and this antenna is bulkier than other designs. If you’re backpacking it in, you typically want the most compact solution possible (this is where the EFT Trail-Friendly, Packtenna, and QRPguys designs really shine).

I will certainly employ the MFF-1984LP regularly–especially on days with less-than-stellar propagation.  I think this might become a go-to antenna for the MTR-3B, LD-11, and IC-705 since all of them lack an internal ATU.

If you’re looking for an affordable, effective wire antenna, I can certainly recommend the MFJ-1984LP.

Do you have an MFJ end fed half wave antenna? What are your thoughts?

Poor propagation but impressive QRP DX with the CHA MPAS 2.0 vertical antenna

One of the funny things about doing field activations is you never know what to expect when you arrive on site, setup, and hop on the air. It’s part of the fun, really. There are certain things you can control, and then there’s propagation.

On Sunday, February 14, 2021 (yes, Valentine’s Day), we had a modest break in the weather and my wife and daughters encouraged me to hit the field to do a quick activation before an afternoon movie marathon. Sunday was the first day I had seen the sun at our house since the previous Wednesday when the cloud ceiling descended to the altitude of our house (3,300′ ASL) and stayed there. It also wasn’t raining incessantly on Sunday, which was a welcome change.

I checked with my go-to propagation friend Mike (K8RAT) before heading out the door and he informed me that things were dismal. I wasn’t surprised: earlier that morning I worked a couple CW stations calling CQ POTA on 40 meters who had very few takers.

Still…I wasn’t going to let propagation stop me.

“Damn the torpedoes, full steam ahead.”

I chose the Zebulon B. Vance Birthplace (K-6856) as my POTA site because it’s the closest park to me that has a covered shelter. I fully expected rain to move in within an hour and really didn’t want that to cut my radio play short.

Once I arrived on site, I decided to deploy my  Chameleon MPAS 2.0 vertical antenna. Why would I use a multi-band vertical instead of a more efficient wire antenna on a day with dodgy prop?

Aren’t you a handsome antenna!

For one thing, I had a limited amount of time and the MPAS 2.0 can be deployed and packed up within a few minutes. Also, I could position the MPAS 2.0 close to the shelter so if heavy rain moved in, I could even keep the base of the antenna protected and pack it up under cover. That and I really didn’t want to fiddle with a wire antenna in the rain if I didn’t have to.

Gear:

On The Air

In short: I only made 12 contacts during this brief activation.

But what I lacked in quantity, I made up for in quality!

Let’s skip straight to the QSOmap of the activation. Keep in mind these are contacts made with a vertical antenna and only 5 watts of power (green poly lines are CW, red is SSB):

Days like Sunday we can’t expect large pileups with five watts, but we can expect normal–albeit brief–openings that allow for some serious low-power DX.

My five watts and a vertical caught Raffaelle’s (IK4IDF) attention in Italy. Sure…he has good ears with a nine element HF Yagi, but I worked him with 5 watts over a distance of 7653 km / 4755.36 mi.

951 miles per watt? Yes, please! I’ll take that!

Parks On The Air isn’t really about working DX, but it’s so much fun when it does happen.

I made a video of the full activation which includes setting up the Chameleon CHA MPAS 2.0. As I mention each time, this is a real-time, real-life video so keep expectations low. 🙂 It includes a number of mistakes on my part.

I’m hoping this odd pattern of bad weather will break soon. I shouldn’t complain: I feel pretty fortunate that we haven’t gotten hit hard with some of the heavy winter conditions affecting much of North America right now.

As soon as it dries up a bit, I’m ready to hike to a local summit for a little SOTA (Summits On The Air) fun! I can’t wait…

POTA Field Report: Activating South Mountains Game Land in gusty winds

6 Comments

Last week, I had a hankering to visit a site I hadn’t activated in a few months: South Mountains Game Land.

This game land is pretty vast and has a number of entry points, almost all of which are very accessible. When I re-visit a site multiple times, I like to try different entrances when I can because it gives me a chance to check out a site better and, frankly, even enjoy a little light off-roading.

I found a western road leading deep into South Mountains from the Wildlife Resource Commission map and decided to explore it and do a quick activation.

South Mountains Game Land (K-6952)

I avoid activating Game Lands on days when I suspect there will be a lot of hunting. Tuesday afternoon was *not* ideal for hunters. Besides being the middle of a work day, it was cold and very gusty.

As I drove about 4 miles into the site, I didn’t see a single car or truck parked in any of the parking areas. I could tell I had the place to myself.

A Few Precautions

It goes without saying that if you’re doing a POTA or SOTA activation in a rural/remote area that has no mobile phone coverage (quite common at the ones I activate), you really need to take a few precautions.

First of all, let someone else know where you’ll be and how long you plan to be there.  I always let a couple radio friends know where I’ll be so if I don’t show up on the air or they don’t hear from me, they could contact authorities to look for me.

Secondly, always take a proper first aid kit. If you get hurt, you need a way to apply first aid until you can get help.

Take a handheld radio with local repeater frequencies pre-loaded. Even though I might not have cell phone coverage, I can almost always hit at least one repeater.

Of course, carry a little food and water with you and make sure your vehicle has fuel as well.

Always wear a high-visibility vest, jacket, and/or cap. Many game lands require these. Besides, would you rather perform and activation or get shot? I don’t like getting shot. I also don’t like the idea of being bear food, so at least pack a little bear mace if you’re in bear country.

When I’m activating a game land I don’t hike deep into the woods. In fact, I try to stay on or very close to a parking area. Even though POTA is becoming a very popular radio activity, I can promise that you’ll likely be the first POTA activator most hunters will see. It’s a good idea to be near areas of activity like a parking spot or road where they’re much less likely to be hunting.

Finally, as I mentioned before, I personally do not activate game lands on busy hunting days.

Of course, check the weather forecast in advance.

On The Air

I found a great spot to set up my station near a ridge line deep in the game lands.

Normally, I’d set up right next to my car, but Tuesday the winds were very gusty so I found a semi-protected area maybe 10 yards off the road. I located a spot with the least amount of overhanging branches (always check for widowmakers and dead trees!).

Gear:

It only took me five minutes to deploy the Chameleon Emcomm III Portable random wire antenna with my arborist throw line.

Random wire antennas require tuners, so I employed the Mat-Tuner mAT-705 Plus.

This site has no mobile phone coverage, so I had no easy way to spot myself to the POTA spots page had I decided to do a little phone/SSB operating. I decided to stick with CW as the POTA spots page will auto-spot me using my information from the Reverse Beacon Network (as long as that system is working).

It’s so rare that I do activations around noon or early in the afternoon, so I decided to start on 20 meters just to see if I could snag a European station.

I felt pretty chuffed to quickly snag the Azores (CU3BL) and a few west coast stations with my 5 watts and a wire. QRP rocks!

I then moved to 40 meters where I worked a number of stations in succession and topped off the activation with one 30 meter contact.

Here’s a QSOmap of this activation:

Not bad for about 40 minutes on the air.

Video

I also made one of my real-time, real-life videos of the activation. Note that my camera died on me perhaps five minutes before I completed the activation, so it will end abruptly. Sorry about that!

My ankle is healing nicely so I’m feeling more comfortable with the idea of hiking again. I’m plotting a SOTA activation with my daughter in the coming weeks.

POTA Field Report: Pairing the Icom IC-705 with the Elecraft AX1 pocket antenna

3 Comments

I think I’ve said before that I don’t like doing things the easy way. At least, I’m coming to that conclusion.

This Saturday (Jan 30, 2021), I had a small window of opportunity to perform a Parks On The Air (POTA) activation.  My park options were limited because I needed to stay near my home and a store where I was scheduled to do a curbside pickup.

The only viable option–since time was a factor–was my reliable quick hit park.

The Blue Ridge Parkway (K-3378)

I plotted a quick trip to the Blue Ridge Parkway Folk Art Center which is centrally-located and, this time of year, there are few visitors.

But what radio take? It had been a couple of weeks since I used the IC-705 in the field, so I decided to take it and rely only on its supplied BP-272 battery pack.

My buddy Mike (K8RAT) had warned me only a few minutes before my departure that propagation was pretty much in the dumps. I’d also read numerous posts from QRPers trying to participate in the Winter Field Day event and finding conditions quite challenging.

Saturday was the sort of day that I should’ve deployed a resonant wire antenna and made the most of my meager five watts thus collect my required 10 contacts in short order.

And that’s exactly what I didn’t do.

You see, a really bad idea popped into my head that morning: I had a hankering to pair the IC-705 with my Elecraft AX1 super compact vertical antenna.

This made absolutely no sense.

I tried to get the idea out of my head, but the idea won. I suppose, at the end of the day, I’m not about taking the easy path (and I’m obviously a glutton for punishment).

I was also very curious if the mAT-705 Plus external ATU could tune the AX1 on 40 meters. More on that later…

Gear:

I arrived on site a few minutes before noon. Setup was fast–that’s the big positive about using the AX1.

Normally, I deploy the AX1 antenna with my KX2 or KX3 and simply attach it to the BNC connector on the side of the transceiver. The AX1 Bipod gives the antenna acceptable stability during operation.

The IC-705 also has a side-mounted BNC connector, but it’s much higher than that of the KX3 or KX2. I’m not entirely sure I could manipulate the Bipod legs to support the antenna without modification.

That and the AX1 needs an ATU to match 40 meters (where I planned to spend most of the activation). Since the IC-705 doesn’t have an internal ATU, mounting it to the side of the transceiver really wasn’t an option.

I employed my AX1 tripod mount for the first time. On the way out the door, I grabbed an old (heavy) tripod my father-in-law gave me some time ago and knew it would easily accommodate the super lightweight AX1.

On The Air

I first tried using the Mat-Tuner mAT-705 Plus ATU to tune the AX1 on 40 meters.

No go.

I tried both the phone and CW portions of the 40 meter band, but the mAT-705 Plus simply couldn’t find a match. SWR was north of 7:1 – 9:1.

Instead of grabbing the Chameleon MPAS Lite or 2.0 from the car, I decided instead to see if the Elecraft T1 ATU could tune 40 meters.

It did.

In short, I logged my ten contacts to have a valid activation, but it was slow-going. All but two of my contacts were on 40 meters CW. The last two logged were on 20 meters CW.

It was a challenge, but I really enjoyed it! And, frankly, considering the propagation, 5 watts of power only using the IC-705 battery pack, and the inherent inefficiencies using a loaded compact vertical antenna and ATU? I was impressed.

Here’s a QSOmap of my 10 contacts:

I bet my effective radiated power was closer to 2-3 watts.

Typically, the AX1 antenna acts almost like an NVIS antenna on 40 meters, but Saturday it favored Mid-Atlantic and the states of IN, OH, and PA. Normally, I would expect more of a showing from the states surrounding North Carolina.

My last two contacts on 20 meters were with KE5XV in Texas and KB0VXN in Minnesota. Not a bad hop!

It took longer to collect my ten contacts than I had hoped and I ran nearly 25 minutes late to my curbside appointment. I’m a punctual guy, but there was no way I was leaving without my ten! 🙂

Here’s a video of the entire activation. Hint: it’s the perfect remedy for insomnia:

Next time I try to pair the IC-705 with the AX1 antenna, I think I’ll try adding a couple more ground radials and see if the mAT-705 Plus can more easily find a match.

One thing I know for sure: the T1 is a brilliant little ATU. While the mAT-705 Plus was never designed to do this sort of match, it’s comforting to know the T1 can.

I’m very curious if anyone else has paired the Elecraft AX1 with the Icom IC-705 or other QRP transceivers. If so, what was your experience? Please comment!
