One of the things I love about our state and national parks is that no matter how often I visit, there’s almost always something new to discover.
This is especially the case as the seasons change from winter to spring.
On March 20, 2022, I carved out enough time in my afternoon to fit in a quick activation of Tuttle Educational State Forest. My main goal, in truth, was fitting in a nice hike–the weather was beautiful, although it was rather gusty.
I needed a little “radio therapy” that day as I had been spending time in the hospital with my mom who had a nasty case of pneumonia. This was a few weeks ago and she’s feeling much better now, thankfully, but those hospital weeks in March were pretty stressful for all of us.
Field activations are such an effective way for me to get in a little exercise, a little radio time, and clear my mind; again, proper “radio therapy.”
Tuttle Educational State Forest (K-4861)
For this trip, I packed the Elecraft KX1 field kit which included my K6ARK EFHW antenna since that was the last pairing I’d used int he field (click here to read that report). I did, however, transfer the KX1 to my new Pelican 1060 waterproof case.
I actually have a solid yellow Pelican 1060 case for the KX1, but after reading about Leo’s QCX-mini field kit built in a clear-topped Peli 1060, I realized how much I missed having a clear lid on the 1060. I checked Amazon and discovered that their blue one was on sale, so I grabbed one. This was a total impulse purchase, by the way.
Today was crazy: when I woke up I thought it would be a good idea to attempt a first activation of DA-0171 in central Berlin after dropping off the kids at day care. So I grabbed my KX2 bag and jumped on my bike.
Shortly later I arrived at the park and pulled up my 40-10m EFHW and started calling CQ on SSB 40m.
It took me about 30 mins to realize that the KX2 was regulating the power down to 5W since both the internal and the external 4Ah battery I took with me were nearly dead.
I had one QSO with a German station and felt I wasn’t really heard anywhere. Then my KX2 started showing “low batt”.
It’s funny because attempting an activation isn’t really what one would call a very important thing, but I do develop quite an ambition if I have decided to get it done. So my only chance was using CW even though I am all but ready for that.
Having read your article about auto-spotting and watched many of your videos including POTA QSO style I didn’t think long and started calling CQ POTA on 20m.
OMG what followed was just amazing!
Fortunately I didn’t run into a classic pileup which would have been super overwhelming for me, but instead about every 2 minutes someone would reply to my call and in a very patient fashion – including one P2P QSO with an operator from Italy.
So all in all I completed 13 QSOs on a “low batt” warning of my KX2.
CW literally saved by butt and I am a very happy person. Without your work for the ham radio community this would not have been possible. So many thanks again.
On a different note: Last weekend (kit building seminar with the club) I had my first DX QSO. It was K3LU who picked up my call from my KX2 and a random wire 9:1 Unun antenna (L-Shape on a mast) with 28 and 17ft legs. I had to sit down and open a beer not able to do anything for about an hour but smile. Such a motivating event and I am happy he was such a great operator instantly QRSing with me and repeating his call. I am in touch with him and looking forward to receive his QSL card which will probably go in a frame.
I also finished the TR-35 and must say I am super impressed. It runs very quietly and the reduced concept is something I really appreciate. When will you take it into the field?
All the best & 73s de Leo (DL2COM)
Oh wow, Leo! I love this–thank you so much for taking the time to share your experience.
First of all, thank you for the kind comments–I’m honored to have even played a minor role in your CW activation. In truth, this is all chalked up to your determination and bravery! I’m guessing what you discovered is what I discovered during my first CW activation: not only is it not as bad as I had imagined, but it was actually fun and got the adrenaline pumping! 🙂
I’m now happy to know that when I hit the Low Battery warning on my KX2, I still have some time left! In truth, the KX2 is so efficient, I’ve made six individual CW 5 watt activations on one charge of the internal battery without even hitting the low battery warning.
Again, this story just makes my day. CW is such a fabulous, efficient, and magical mode! Good on you for diving in, OM!
I also think it’s brilliant that you worked Ulis (K3LU). You couldn’t have worked a better op for your first CW contact–he’s the real deal and a wonderful fellow. Not only that, but he has some amazing QSL cards!
And the TR-35? I couldn’t agree with you more. I did an activation with the TR-35 last Friday so a video and field report is forthcoming!
Thank you again, Leo! I hope others share their experience hitting CW for the first time (hint, hint!).
The (tr)uSDX has been a much-anticipated QRP transceiver for those of us who love playing radio in the field.
What’s not to love? It sports:
Up to 5 watts output power
CW, SSB, FM, and AM modes
A built-in microphone
Five bands: 80, 60, 40, 30, and 20 meters
A super compact and lightweight form factor
An open-source hardware and software design
Super low current consumption in receive
A super low price of roughly $89 US in kit form and $143 US factory assembled (via AliExpress, but there are numerous other group buys and retailers)
Frankly speaking, this sort of feature set in such an affordable package is truly a game-changer. Back when I was first licensed in 1997, I could have never imagined a day when a general coverage QRP transceiver could be purchased for under $150 US. The price is almost unbelievable.
My initial impressions
On Wednesday, March 30, 2022, I took the (tr)uSDX to the field to attempt a Parks On The Air (POTA) activation. I had only taken delivery of the (tr)uSDX about 15 hours beforehand and had only had it powered up for a total of 30 minutes the previous day. Most of that time, in fact, was checking the power output at various voltage settings into a dummy load. I did make one totally random SSB POTA contact shortly after hooking the radio up to my QTH antenna.
I knew that taking the (tr)uSDX to the field and making an activation video might not be the best idea having had so little time to play with the radio and get to know it in advance, but then again, I was simply too eager to see how it might perform. That and I always believe there’s value in sharing first experiences with a radio. Continue reading Video: Taking the new (tr)uSDX QRP transceiver on a CW POTA activation!→
I mentioned in a previous post that my personal Activation Challenge for 2022 was “to build a new antenna each month and deploy it at least once that month during a field activation.”
For February, I decided to purchase and build a counterpoise-less end-fed half-wave kit from from Adam (K6ARK). This kit is available on Amazon.com for a mere $19.95 (affiliate link).
The build itself is pretty straight-forward and not terribly complicated. With that said, you do need a fine soldering iron tip and a little dexterity to manipulate these super tiny components. Adam includes instructions for building an EFHW with a counterpoise, without a counterpoise, or a random wire antenna. The coil can be configured as a a 49:1 Unun, 9:1 Unun, or 1:1 Balun.
If you choose the EFHW route you will need to solder one surface-mount capacitor on the board. If you’ve never worked with surface mount components before, take your time and use a good magnifying glass.
Blue Ridge Parkway (K-3378 NC)
On Monday, February 21, 2022, on my way back from town, I hopped on the Blue Ridge Parkway and drove to one of my favorite roadside spots on a grassy hill surrounded by trees.
Since I configured the K6ARK kit as a counterpoise-less EFHW, I wasn’t entirely sure how stable the SWR would be in the field. For this reason, I was a wee bit nervous pairing it with my MTR-3B since that little radio lacks an SWR meter and really needs a good match.
I decided, instead, to pair the K6ARK antenna with my Elecraft KX1 which has a built-in ATU that can both monitor the SWR and find an impedance match if needed. Of course, I turned off the internal ATU for the activation, but if I needed it, I knew I could engage and use it.

Maybe it’s just in the nature of those of us who love QRP.
We get a small thrill out of seeing what we can accomplish with less.
AX1 Doubts?
On the morning of February 7, 2022, I received an email from a subscriber in South Carolina who had placed an order for a new Elecraft KX2 and an AX1 antenna package. He picked this particular combination because he wanted the most simple and easy-to-set-up field radio system for impromptu CW POTA activations and a little random QRP fun.
He mentioned that, at his age, mobility is a bit of an issue and even though he knew a wire antenna would be more effective, deploying it while walking on uneven ground just wasn’t in the cards. The AX1 was a much more manageable and packable system. Plus, as he said, “I’m not going out to work DX. I just want to play and have fun.”
Only a week after placing his order, he was having buyer’s remorse which prompted his message.
He explained that he had exchanged emails with a friend in his radio club who told him he’d made a foolish mistake and that the AX1 was completely ineffective as an antenna and would only lead to disappointment. His friend said [direct quote here], “I owned [an AX1] for a month and was never able to make a single contact. It is really good at being a dummy load and nothing more! This thing shouldn’t be marketed as an antenna. It doesn’t work.”
I pointed out that I’ve used the AX1 numerous times in the field and have yet to be disappointed.
Before I used the AX1, I too, was very skeptical but after actually using it (instead of simply theorizing about it) I found it’s one of my most valuable antennas for a quick and fruitful activation. I pointed him to this playlist that includes all of my AX1 activations on YouTube. In all of these activation, I’ve limited myself to 5 watts as well even though the antenna can handle a full 10 or 15 watts from the KX2 or KX3.
I told him I’d been planning to pair the AX1 with my Mountain Topper MTR-3B and, it turned out, that very day a small window of opportunity opened in the afternoon. I told him we could both see how the AX1 might perform with three watts of power, especially since he’d planned to use 10 watts with his KX2.
A few months ago, Mike (KE8PTX), contacted me with info regarding his latest 3D-printed creation: a compact housing for an end-fed half-wave balun.
Mike’s 3D drawing
He called it the “Oreo Balun.”
Once printed, and after he wound the coil and installed the BNC, he sent this photo:
It’s cute, isn’t it?
He then surprised me by putting it in a padded envelope and sending it to me as a gift. Wow–thanks, Mike!
Oreo plans
End-Fed Half-Wave antennas are popular portable antennas for a reason: they’re effective!
They’re compact, easy to deploy, and resonant.
I only needed to attach some wire to the Oreo Balun, trim it, and hit the field!
Earlier this year, my buddy Vlado and I built two doublets with some scrap wire I had in my antenna parts box. I measured the amount of wire I had left from that same spool. I knew it wasn’t enough length for a 40 meter EFHW, but I did think there was enough for 30 meters.
After giving it a bit of thought, I liked the idea of having a dedicated 30 meter EFHW. For one thing, 30 meters is a great band for field deployments and in the past this band has saved my bacon when either 40 meters or 20 meters was wiped out. Thirty meters is also a refuge WARC band during contest weekends. In addition, a 30 meter EFHW is short enough that it could be deployed on most SOTA summits (which often have shorter trees).
Fortunately, I had just enough wire for 30 meters. IN fact, after trimming the antenna, I only had about two feet of wire to spare. It’s as if I had planned it! I would have never guessed that spool of scrap wire would have made two doublets and one 30 meter EFHW.
There are days when I leave the QTH and have no idea if I have enough time to fit in a park or summit activation. Because of this, I always keep a radio field kit in the car.
On Monday, January 31, 2022 I had an appointment-packed day ahead of me, but I was hopeful I might be able to squeeze in a quick activation of some sort.
Specifically, I had a new-to-me super easy, drive-up SOTA site in mind: Peach Knob (W4C/CM-097). In fact, it’s a bit odd that I hadn’t activated this site before. It must be the most accessible summit (to me) in the area.
After a 2:00 appointment in downtown Asheville, I drove 15 minutes to the summit of Peach Knob where I discovered 1.) there was almost no space to park and 2.) what little space there was was taken up with crews working on a cluster of communications towers. In situations like this, the last thing I want to do is get in the way; that sort of activator persistence could lead to “no trespassing” signs in the future.
The site also reminded me that what I love about SOTA is the hike to the summit. Sites like this one are wedged between private property and city property–I just feel like I’m in the way, arousing neighborhood suspicions, and just doing the activation for the points. I’m not a points guy (though I’ll do a happy dance when I accumulate 1000 for ‘Mountain Goat’ status sometime within a decade at this rate).
Moving forward, I think I’ll skip drive up sites like this one; at least for HF activations.
At this point, I pretty much abandoned the idea of a field activation as I’d taken up the wee bit of free time in my schedule just checking out Peach Knob.
I’ve been spending more time with my Mountain Topper MTR-3B (“Tuppence”) recently and have been thoroughly enjoying this little radio’s companionship.
Since I made a dedicated ultra-compact field kit for the MTR-3B, it has also been even easier to toss it in my backpack and take it on little field adventures. The field kit is truly a grab-and-go and even includes a throw line and weight.
On Friday, January 28, 2022, after a total of six individual park activations during the previous two days (a POTA RaDAR run and my first 2020 Antenna Challenge activation) driving back to the QTH I thought, “surely I can skip doing an activation today.”
That quickly turned into, “Wait a minute…I’ve got enough time to fit in both an activation and a hike!”
So I made a quick detour off of I-40 to visit the Clear Creek access of South Mountains State Park.
South Mountains State Park (K-2753)
I pulled into an empty parking area; not really a surprise on an early Friday afternoon. In addition, I figured many were out grabbing bread and milk since winter weather was in the forecast.
On January 26, 2022, I fit in multiple park activations in one day as a RaDAR (Rapid Deployment Amateur Radio) run. My hope was to activate four or five sites between 14:00 – 21:30 UTC.
Here are the field reports and videos of my first three activations:
The next park in my run (#4) was either going to be my last activation, or second to last depending on my available time.
After visiting with my buddy, Hamilton, at his ceramics studio in Morganton (read about that in the previous report) I looked at the time and decided I could fit in a very quick activation of Johns River Game Land (#4) en route to Tuttle Educational State Forest (#5).
I made up my mind en route that I’d use my fastest-to-deploy combo: the Elecraft KX2 and Chameleon CHA MPAS Lite.
I really wanted to be in and out of the site within a 20 minute window. That’s actually very doable as long as I could rack up at least ten contacts in 10-15 minutes. Some days, propagation can make that a tall order, though!
Johns River Game Land (K-6916)
Johns River actually has a number of access points and, frankly, none of them are exactly “bucolic.” Other than the river itself which is beautiful and the main access point for the river which is well-maintained, most of the game land parking areas are filled with litter.
I chose a parking area for this activation which has, in the past, looked like a dumping ground. I was pleased when I pulled into the parking lot this time to find it much cleaner (no old refrigerators or sofas dumped at the far end of the lot) but then again the snow on the ground was likely hiding quite a bit of litter! My philosophy is to always leave a site cleaner than I found it, but Johns River often has so much littler, I could spend a week picking up trash.
After doing a very short intro for my activation video, I set up the Elecraft KX2 and MPAS Lite antenna in a matter of two minutes.
I started calling CQ POTA (with my fingers crossed!) on 40 meters and was very pleased that chasers were out and about!
I worked my ten contact in 9 minutes and then went QRT! Woot! Here’s the log sheet:
In this short activation, there was actually a P2P with Max (WG4Z) who was just up the road at Tuttle Educational State Forest. We were definitely working each other via ground wave.
The contacts were flowing so well, that I wanted to stay on the air a bit longer, but I knew to fit in Tuttle and a hike, I really needed keep moving. As soon as I worked my ten, I hopped off the radio.
While I like putting more contacts in the log–especially when they’re flowing so freely–it was actually kind of fun to validate this activation in somewhat of a “sprint.”
QSO Map
Here’s what 5 watts and the MPAS Lite yielded in nine minutes on the air:
Activation video
Here’s my real-time, real-life video of the entire activation. This must be one of the shortest activation videos I’ve ever made:
Thank you so much for reading this short report and coming along with me on this RaDAR run! I’ll be posting Park #5–Tuttle Educational State Forest–soon where I catch up with Max (WG4Z) and we work park-to-park once again.
As always, I’d like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I truly appreciate the support.
These are crazy times we’re living in these days (at time of posting). I wish all of you good health, safety, and peace–especially our good friends in Ukraine.
Let’s all treat each other with kindness and respect this week as we remember that all we’ve got on this old planet is each other.
You may have noticed a common theme in my field reports: basically, it’s rare that I plan out an activation more than 24 hours in advance.
Indeed, due to my “dynamic” (I think that’s a good word for it?) family schedule, I often don’t plan an activation more than one to two hours in advance.
But last month, I saw an opportunity open on Wednesday, January 26, 2022. Basically, I had from early morning until late afternoon to play radio.
Making plans
At first, I thought about striking out early and hitting some of the parks that are a little further afield–parks I hadn’t visited in a couple years, or some new-to-me parks.
Then, I hatched an idea to activate two SOTA summits. Both would qualify for bonus winter points and both were technically doable in the time I had allotted. It would involve about 9-10 miles of hiking in addition to 3 hours of driving plus allotting for the time I’d actually spend on the air. It would equate to a very early departure and some steady hiking.
That Tuesday evening, I started putting the plan together, downloading all of the maps, preparing my SOTA alerts, and packing my SOTA pack. I spent the better part of an hour plotting and planning these activations.
Then the realization hit me: the trails I’d be hiking were likely covered in snow and ice which would slow me down considerably especially since my Yaktrax Traction Chains hadn’t yet been delivered. I realized the schedule was just a little too tight. There’s be no room for mishaps and if I made the trip I really wanted to hit both summits in the same day. So, I saved all of my maps, links, and notes to do this multiple SOTA run in the near future.
Back to the drawing board!
I decided that I did like the idea of doing multiple activations in a day, so why not fit in a RaDAR run?
RaDAR (Rapid Deployment Amateur Radio) is basically an activity that can be combined with summits and/or park activations and the idea is simple: you complete multiple rapid field deployments within 24 hours.
If you’d like more information about RaDAR, check out this webpage. Parks On The Air even has a few awards for RaDAR runs–it would be fun to apply for one of them (thanks, WD8RIF, for the heads-up!).
I so rarely have enough time to consider more than two or three activations in a day that the idea of fitting in four or possibly five activations was very appealing.
