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

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!

My review of the Icom IC-705 QRP transceiver

I recently published my full review of the Icom IC-705 over at the SWLing Post. If you’ve been following QRPer for long, you’ve likely seen this little radio in action.

If you’d like to read the full review, which was originally posted in the February 2021 issue of The Spectrum Monitor magazine, click on this link to visit the SWLing Post.

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

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

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

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?

Tom’s “Salt Water Amplifier” approach to portable & pedestrian QRP DX

Many thanks to Tom (G0SBW) who writes:

Hi Thomas

I thought I would drop you a line to say how much I am enjoying your posts – so much so I have subscribed.

I came across your posts while researching POTA (it is now available to hams in the UK and I have signed up for it). […]Most of my QRP sessions are pedestrian mobile but as I get older (I’m 82) I think they will become more /P.

What is quite different for me is that almost all of my operating is done from salt water marsh areas – so no trees at all for antenna supports. Of course, there are ways of getting around this problem by using masts with verticals, and mag loops. Using the readily available salt water amplifier, I’ve had quite a bit of DX success with SSB QRP. I’m now busy getting my CW up to scratch to get along better with POTA.

Here is a link to a YouTube video I made last year which shows a couple of my type of activity. It was made for a presentation so it is a bit long at 30 minutes:

73. ( or maybe that should be 72?). and Keep safe

Tom G0SBW

Thank you, Tom! Brilliant presentation! Thank you so much for sharing (although you’re making me homesick for the UK). I love the idea of the sea water amplifier effect and have employed that in the past to my advantage.  I wish the coast were a little closer to my QTH, but sadly it’s a good 4.5 hour drive at minimum.

Thank you and please let us know if you post new videos.

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):

Click to enlarge.

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.

Video

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…

Pairing the Elecraft KX2 with the Chameleon MPAS 2.0 at Lake James State Park

For the past four days here at my mountain QTH in North Carolina, I haven’t seen the sun. The cloud ceiling has been low and our house has been in the middle of it. It’s been rainy and foggy with temps floating a few degrees above freezing.

Last Tuesday (February 9, 2021), however, we had one day with glorious weather and I’m so pleased I carved out 90 minutes to perform a park activation on my way back home from a short trip.

I picked Lake James State State Park (K-2739) because it’s such a short detour and has numerous spots where I could set up my gear.

The temperature was a truly balmy 60F/15.5C–possibly even a tad higher.

Lake James State State Park (K-2739)

On my way to Lake James, I knew I’d use my Elecraft KX2 (it was the only transceiver I had on this trip) but debated what antenna to deploy. I chose the Chameleon MPAS 2.0 vertical antenna because, to my knowledge, I had never paired it with the KX2 and I enjoy shaking up my transceiver and antenna combos.

Gear:

The brilliant thing about antennas like the CHA MPAS 2.0 is how quick they are to deploy: it takes me all of three minutes or so.

On the air

Since the Elecraft KX2 has a built-in battery and built-in ATU, I basically connected the radio directly to the antenna and was on the air in moments.

The CHA MPAS 2.0 is the vertical equivalent of a random wire antenna: it’s not resonant on any one frequency and requires an antenna tuner to achieve a good SWR.

As I mentioned in the video (below) I always keep my expectations low when deploying a vertical antenna in areas like western North Carolina where ground conductivity is poor.

Maybe the antenna decided to prove me wrong, because I hopped on 20 meters CW and logged a number of stations across the country including Washington state and British Columbia with a measly five watts.

It also happened that my buddy and fellow POTA activator, Steve (KC5F), was just down the road activating another site in the same county. It’s rare that Steve and I can work each other because, typically, we’re too close for skywave propagation and too far for ground wave. Not this time! We were close enough for ground wave on multiple bands–it was great fun working him park-to-park on every band I tuned.

I moved from 20 meters to 17 meters, to 30 meters, 40 meters and back up to 20 meters SSB.

The great thing about using the MPAS 2.0 is how incredibly easy it is to pick up and move from band-to-band–there’s no manually tuning a coil or changing links on a multi-band diplole. In fact, the MPAS 2.0 covers 160-6 meters, so I’ve lots of options if band conditions are wonky.

Video

Here’s an unedited video of the entire activation:

Click here to view on YouTube.

In the end, here’s how my QSOmap looked with 32 stations logged:

I look back at activations like this and am reminded of the magic of HF radio. It’s truly phenomenal, in my mind, that with less power than it takes to light an LED bulb, I can make contacts across the continent pretty effortlessly–CW or SSB–even during the solar doldrums! Good fun!

In other news, my ankle is healing nicely and once this cycle of nasty weather clears, I’m looking forward to putting some SOTA sites on the air!

How about you? Do you have any field radio plans? Has the weather or C-19 lockdowns gotten in the way? Please comment!

POTA Field Report: Activating Kerr Scott State Game Land with the Elecraft KX2, 5 watts, and a not-so-resonant wire

Some of my most enjoyable field activations are those involving the least amount of equipment and accessories. Maybe it’s my “less is more” mentality, but it is amazing when all I need to get on the air is one radio, a feedline, logging notebook, and a simple antenna.

That was my set-up earlier this week (February 8, 2021) when I activated Kerr Scott State Game Land–a site I hadn’t visited since last summer.

Kerr Scott State Game Land (K-6918)

I was the first person to activate Kerr Scott State Game Land back in June of 2020.

I vividly remember that activation because, as I noted in my field report on the SWLing Post, it was Kerr Scott that taught me an invaluable lesson:

“[I]f you don’t have a “spot” of your activation on the POTA site, it’s like you don’t exist.”

This was truly a tipping point that lead me down the path of doing CW activations in order to benefit from auto-spotting via the Reverse Beacon Network (RBN). Only a couple weeks after this activation, I made my first CW activation and the rest is history. While I still use SSB during activations, CW has become my favorite mode even though I’m still not that great of an operator.

I speak about this a bit more in my activation video below.

Gear:

Once I arrived on site, I deployed my EFT Trail-Friendly 40/20/10 meter end-fed resonant antenna.

The last few times I deployed this antenna in the field, it hasn’t been resonant on 40 meters and I suspect this is due to damage to the coil near the end of the radiator. I decided I’d give it one last test  by suspending it in an overhanging tree branch about 50 feet high so it would not touch other branches.

When I turned on the KX2, I set the internal ATU to “bypass” and tested SWR. Sadly, it was unacceptable, so I re-activated the ATU to get a good match.

My buddy and fellow POTA activator, Steve (KC5F), reminded me recently that the radiator on this antenna can be replaced with enough wire to make a simple end fed half wave. That’s probably what I’ll do because, frankly, this antenna has served me so well for five years and over 150 park activations I’m not ready to simply toss it. I will need to order some proper wire for the EFHW, though!

On The Air

Since I have no mobile phone/Internet service at this site, I decided to make this a CW only activation, hopefully taking full advantage of auto-spotting to the POTA spots page.

I started on 40 meters because I had pre-arranged with my buddies Mike (K8RAT) and Eric (WD8RIF) to listen for me on 7063 kHz. I did this in case auto-spotting wasn’t working, which does happen from time-to-time. It’s always important to have a back-up if possible especially for sites (like this one) that carry significant travel time.

I hopped on 40 meters, called CQ POTA and within 29 minutes, I logged 26 stations. That’s about as much activity as I could possibly expect during a Monday morning activation!

Next, I moved to 20 meters and started calling CQ. The first station I worked was CU3BL in the Azores, then WD5GRW in Texas, AB6QM in California, then IK4IDF in Italy, and finally KH2TJ in California.

I then moved to 30 meters and worked N5GW in Mississippi before going QRT with a total of 32 stations logged.

Not at all bad using 5-10 watts!

One of the things I rarely mention in my videos and field reports is how much I love the trips to/from an activation site. I’m a traveler at heart and while I’ve been fortunate enough to travel to and live in some pretty amazing countries and cities, I still have a deep appreciation for simply driving through the countryside and taking in the scenery. I appreciate the mundane as much as I do the majestic. It’s a beautiful drive.

Kerr Scott Game Land is located in the little farming community of Boomer, NC which, I understand, was named after its first postmaster, Ed “Boomer” Matheson.

Warrior Creek, next to my activation site at Kerr Scott

Before it was called Boomer, the community was known as Warrior Creek–the very creek running through Kerr Scott Game Land.

Even though I know there’s no connection, when I hear the name Boomer I can’t help but think of the incredibly cute and cheeky red squirrel that we WNC natives call “Boomers.”
