Elecraft KX2 Field Kit
by Cameron (KO6BYB)
I wanted to share a tiny KX2 kit I made to fit the Seahorse SE56 (QRPer affiliate link) case. Just upgraded to my General and finally got the HF transceiver of my dreams. Haven’t made it out to the field since I got it last weekend, but I had some spare time (that I should have been sleeping) and whipped this up. Fits basically a whole station in the case:
This article continues my series from our 2024 road trip across the United States (Six Weeks and 7300 Miles: Activating on the Road). I hope to wrap up the series with one last article soon. In this report, I will cover the six National Parks (NPs) that we visited during our trip. I activated five of them for the Parks on the Air (POTA) program using CW mode at 5 watts. A previous report on Stealth Activating with the KX1 Antenna System provided activation details for three of the parks (Badlands NP, Yellowstone NP, and Grand Canyon NP), so I will not reproduce activation details here, but I will include more of Becky’s pictures.
Each of these NPs is spectacular in its own right, and also distinctly different from each of the others. We were able to see some of the sights, but by no means had enough time to do them justice. In fact, as we completed our drive through Yellowstone NP, Becky and I committed ourselves to going back again and spending much more time to see its wonders.
As I reflect on our visits to NPs on our trip, it occurs to me how beneficial it was to buy an Annual America the Beautiful National Parks and Federal Recreational Lands Pass before we left on our trip.
The pass costs $80 for a year, and generally covers the admission of one vehicle and its occupants. We were able to save on admission costs several times over, making this one of the best NP values going. Having now completed 62 trips around the sun, when we next visit NPs, I am eligible for an even better value, the $80 Senior Lifetime America the Beautiful Pass.
Badlands NP
The first NP we visited on our trip was Badlands NP in South Dakota. We spent a couple of nights and days based nearby in the town of Wall, so we were able to take two drives through the park. There is a stark transition from rolling plateau north of the park to the spectacular peaks and canyons of the badlands. Rapid erosion has been shaping the terrain for about 500,000 years with the Cheyenne and White Rivers cutting their way through the terrain. The resulting landscape is both beautiful and severe.
While visiting the park, we were privileged to see a variety of wildlife. We saw a number of bison, ranging from small herds grazing in fields along the road, to an individualist who took a liking to the taste of grass beside one of the overlook parking areas. There were also bighorn sheep and pronghorn antelope wandering other parts of the park. There was abundant bird life, from a disoriented prairie chicken that accepted water from concerned visitors, to birds of prey soaring high above. Becky particularly enjoyed the frenetic activity of the residents of Roberts Prairie Dog Town.

During our visit, we stopped at an overlook parking area for Becky to take pictures of the spectacular scenery, including the aforementioned bison. While she was doing this, I took the opportunity to do a stealth activation of the park, which is documented in an earlier Field Report here on QRPer.com, linked as K3ES: Stealth activating with the AX1 Antenna System.
I managed to catch the photographer in action during a lull in my activationOf course, Becky caught me in action, too
Yellowstone NP
We knew when planning our trip, that we would not have time for a proper visit to Yellowstone NP. In fact, we intended to hold off on visiting until we had time for a dedicated trip. But throughout our drive, Becky kept searching the available maps for opportunities and possibilities. As we traveled through Montana, she noticed that we could fit in an abbreviated trip through Yellowstone and Grand Teton NPs if we adjusted our route. Consequently, we found ourselves spending the next night in Gardiner, MT, just outside the north entrance to the park.

Glenn W4YES and I headed to Camden, SC the first week of April for some much needed rest and relaxation. Usually when I travel, I schedule a POTA activation or two. However, this trip I decided to try something new – getting on the air QRP at our Airbnb.
Camden is the oldest inland community in South Carolina. According to the town’s website, the earliest permanent settlers arrived in 1750. They experienced a crushing defeat during the Revolutionary War when the Patriots were defeated in the Battle of Camden. After the Civil War, the town “evolved into a tourist mecca for Northeners and Midwesterners seeking a warmer winter climate.” Those tourists brought money and an equine culture developed around racing and polo.
Our first day in Camden, we visited the Revolutionary War Museum. Though small in size, the museum’s exhibits are of excellent quality. They do a great job explaining who lived in the area, the quandary they faced as to whether to be a Loyalist or Patriot (it wasn’t as easy a choice as it might appear), and battles fought there.
Our second day, we explored the National Steeplechase Museum. This museum explores the history of steeplechasing and the personalities involved – owners, trainers, jockeys as well as those who care for the horses. The museum pays homage to Marion duPont Scott who developed the Springdale Race Course where the museum is located. This race course hosts two prominent annual competitions – the Carolina Cup and the Colonial Cup.

We also spent some time driving through and walking in the historic neighborhoods of the city. The weather was gorgeous! Everywhere we looked, there were flowers – azaleas, wisteria, viburnum, and dogwoods (including the pink variety we do not see in Savannah).

After exploring the area, it was time to explore the airwaves QRP at our Airbnb. To do this, I brought Craig, my KX2, and a home-brew linked dipole antenna. This is an antenna I built three years ago, when I first got into ham radio. At that time, I had no home station but wanted to get on the air portable for POTA. Despite knowing almost nothing about antennas, I built a usable dipole that became my main POTA antenna for quite a while.

Why did I bring this antenna to Camden? I have the opportunity this month to try the CFT1, a QRP transceiver, by Jonathan KM4CFT. Because the rig does not have an internal antenna tuner, I am reacquainting myself with the subject of resonance and why it matters in antennas.
I set up a home-brew linked dipole Wednesday evening under some trees in a space between the Airbnb and a small lake on the property. The antenna was roughly 20 feet in the air.

My RigExpert Stick analyzer gave me 2.1 at 7.040 –
Thinking I could do better, I moved the antenna (a real pain to do with a dipole) to a different tree with a limb 30 feet high. (Frankly, Glenn and I were amazed I could snag that limb.) This setup generated better a SWR reading – 1.61 at 7.040 MHz.
Now the true test – how well would I be heard?

CW nets are a great place to get on-the-air experience with morse code. It was my code buddy Caryn KD2GUT who first introduced me to the OMIK net. I found those who participate in this CW net to be welcoming and accepting of CW operators of all levels of proficiency. Over the past several years, the ops in this net have watched my skills grow and become friends.
Dennis NT4U and Steve W0SJS split net control station (NCS) duties. This evening, it was Dennis’ turn as NCS. As he is located in northern Georgia, I figured he would hear my QRP signal. He did and checked me into the net with a RST of 589. The icing on the cake was that I heard a station he was unable to hear – Charles AI4OT in Virginia – due to the S9 noise at Dennis’ location this evening. I notified Dennis of Charles’ check in so he was added to the check-in list for that evening. Way to go homebrew linked dipole and Craig!
The next day, Glenn did some exploring and found a better location on the property – a hill behind the Airbnb and some sheds. Several large oaks in this relatively open area offered prime limbs to snag with an arbor line. I installed the antenna on a limb roughly 25 feet up in the air.

Before attempting to check into another net, I spotted myself on QSO Finder, a new website and spotting tool by Mike N4FFF and Becky N4BKY of Ham Radio Duo. I had three exchanges, one each with Joel KE8WIC, Tom NG4S, and James KJ3D.
Spotting myself on CW QSO Finder
On Thursday evenings I check into the Sideswiper Net, a wonderful group of guys who meet on 40 or 30 meters (depending on propagation). Most of those who check in use a sideswiper (also known as a cootie) key but, like the OMIK CW net, they are welcoming of anyone who wants to participate no matter the level of proficiency or key. I’ve asked lots of questions of the members and appreciate their patience schooling me about CW nets.
The NCS this evening was Darrell AA7FV who is located in Arizona. The noise on 40 meters was rough but Darrel did copy me with a RST of 349. Two other stations – Bill WA4FAT in Alabama and Steve W1SFR – also copied me at 559 on this band.
When the net moved to 30 meters, my signal was worse. However, I expected that, as by this time it was dark and I didn’t want to mess with lowering the antenna to disconnect the link between the 40 and 30 meter wires. Darrel in Arizona could barely hear me (he gave me a RST of 129) but Bill could still copy me and acted as relay between our signals. I was thrilled that I had now checked into both nets QRP this week!
the RBN picked me up again
Even better, after the Sideswiper net, my code buddy Caryn KD2GUT and I were able to have our weekly code buddy QSO. We managed a 20 minute QSO on 40 meters before being swallowed up by noise and QRN on her end. Caryn is located on Long Island, NY. The previous night in the OMIK net, my signal was a 229 at her QTH. But tonight, we were both 599 and rocking it on the airwaves.

During the Sideswiper net and my code buddy QSO, I sat head copying in the dark under the moon and thought, “It doesn’t get any better than this, right?”
Before we left the Airbnb Friday morning, Glenn spied several pitchforks sitting by the sheds. We picked one up and decided to have some fun, with our version of the famous piece “American Gothic” by Grant Wood. I had a difficult time keeping a straight face (watch the video linked down below) but eventually we got the shot.

QRP has its limits; however, I was sufficiently impressed by my experience on this trip that I will travel with a rig from now on. I’d like a better antenna and have ordered an EFHW as that is probably my best bet for a resonant antenna. This hobby NEVER becomes boring because there is always something to learn.
I look forward to trying the CFT1 and my new EFHW antenna when it arrives. How will that turn out? Stay tuned…

In the chaos of the past two months, I managed to post a few field reports out of chronological order. I’m probably the only one who notices—these aren’t sequential stories, after all—but since I was there for each activation, it feels odd when the timeline’s off.
Case in point: you might recall this recent post where I shared how I finally landed an Elecraft K1 field-portable transceiver. I’d been hunting for a K1 for years, so I was thrilled when this one popped up locally in North Carolina.
Last month, I published this field report where I paired the K1 with my AX1 antenna for a low-profile (but high-performance) activation in Pisgah National Forest.
But here’s the thing: that was actually my second activation with the venerable K1. The first one? It took place along the Blue Ridge Parkway on February 24, 2025.
Taking the K1 to the Field!
It’s always exciting to take a new radio to the field—especially one I’d been chasing for so long. I purchased the K1 back in August of last year. As soon as it arrived, I tested it and realized it was in serious need of alignment.
I brought it over to my friend Vlado (N3CZ), hoping to use his signal generator to sort it out. Unfortunately, we didn’t have time that day, so I left the rig at his QTH. Then Hurricane Helene hit, and… well, suddenly it was 2025.
We finally got around to the alignment in February. As soon as it was dialed in, I hit the field.
Blue Ridge Parkway (US-3378)
I made my way to a familiar spot along the Blue Ridge Parkway—the Folk Art Center—and set up the K1.
Mine is a four-bander (40, 30, 20, and 15 meters) with both the optional internal ATU and AA battery pack. To give the internal tuner a little workout, I paired it with my trusty Tufteln 9:1 End-Fed Random Wire antenna.
Once deployed, I hit the ATU button, and the K1 quickly found a solid 1:1 match. With logs at the ready, it was time to hit the airwaves!

I tried using an Alpha Antenna 100w 10-40m mag-loop antenna for a POTA activation. I operated on FT8 so I could monitor where my signal was being received by using the PSKreporter.info real-time signal reports from stations that spotted my transmission. I really didn’t know what to expect or how a loop antenna would perform in the park compared to a vertical or wire antenna. Did it work? You bet. Would I recommend it? I’ll share my observations and results below and let you know at the end.
I bought this antenna used on QRZ.com’s swapmeet. It was clear to me upon receiving it that the prior owner had taken very good care of the antenna. I set it up on my patio for a quick test before heading to a park.
Mag Loop Test from the N2YCH QTH
It sets up quickly. The tuning is a little challenging to learn at first but there’s no doubt when you get it right, since the received signal is easy to peak once you find resonance. The tuning knob has three turns from 40m up to 10m. Moving it slowly from the bottom of the HF band up to the top, you’ll find the sweet spot and you can peak the received signal on your radio’s S-meter. I checked it with my RigExpert antenna analyzer and as you’d expect, the bandwidth was very narrow, but it was resonant and the SWR was 1.4:1.
The Alpha mag loop can do 100 watts SSB but only 5 watts on digital modes. I fired up my KX3, set it for 5 watts and called CQ. I made three quick contacts and was satisfied that the antenna was working. I checked the spots on pskreporter,info and found it interesting to see a narrow band of stations from Minnesota and Wisconsin down to Florida spotting me.

On to the park: Indian Well, US-1684 in Shelton, Connecticut
Knowing that the antenna was working, I brought it out to one of my favorite places to activate, Indian Well State Park (US-1684). Again, set up was fast and I was able to tune up on 20 meters pretty easily.
Alpha Magnetic Loop Antenna at Indian Well State Park in Connecticut
The antenna was receiving the FT8 signals at S-9 with the KX3’s pre-amp off and you can see below that I was decoding nearly 50 stations per FT8 cycle. If you look closely at the JTAlert screenshot below, you can see I was receiving stations from all over the US as well as Canada, South America and Europe. There’s no doubt the mag-loop can hear very well.
Forty-seven stations are being received and decoded. POTA stations in the bottom right pane
I called CQ and had a few responses right away. However, I was finding it challenging to get stations to reply. It took almost an hour for me to get my 10 contacts to activate the park, which is unusual. I should mention that the space weather was acceptable, sitting just below Kp3, so that wasn’t the reason.
Once again, I checked Pskreporter.info. Interestingly, it had the same pattern of spots that I saw when testing the antenna at home, a band from Minnesota to Georgia. Of the first 10 contacts I made, four were in North Carolina, two in Florida and the rest were coming from within that narrow band who could hear me.
Spots from US-1684 using the Mag Loop
I understand that a mag loop is directional, so I tried moving it 90 degrees to see if it made a difference. Not really. The spot map looked the same after the change in direction. I was able to receive a few more EU stations after I moved it. I did have to re-tune the antenna after I turned it, the SWR had gone through the roof.
For comparison, after struggling to make contacts on the loop, I decided to set up my “go-to” antenna of a 17’ telescoping whip on a 10’ mast with a counterpoise.
Buddipole with 17’ telescoping whip and elevated counterpoise
I unplugged the mag loop and plugged in the vertical using the same transceiver set at 5 watts. Take a look at the stations who could spot me on PSKreporter now…
PSKReporter Spots with vertical antenna on 20m QRP
Clearly, that same 5 watts from the KX3 had better coverage on the vertical than using the mag loop.
Here’s a screenshot of WSJT-X on the vertical (click image to enlarge):
WSJT-X and JTAlert reception using 17’ vertical with counterpoise
Once I switched to the vertical, I knocked out 10 more contacts in just 20 minutes.
So, after all that, what do I think?
The Mag Loop sets up quickly, uses very little space and finding resonance isn’t difficult to do. It receives very well, of course this is one of the true advantages of mag loops, is their inherent ability to receive well in noisy environments.
As an antenna to use for transmission? Well, I think this is where the challenge lies, for me anyway. It was certainly hearing stations way down in the noise from far away. However, as you can see by my real-time reception reports, it did not give me the wide transmission coverage that I’m used to with the vertical. Maybe this would be different on SSB with 100 watts, but it’s a difficult to measure SSB reception like you can with digital.
Can you activate a park with it? Yes, indeed. Would it be my first choice for POTA? Probably not. If you were using this on SSB, the antenna itself (not the radio) would need to be re-tuned for every frequency change (if you were hunting), which is not convenient. If you are the activator, then you could tune up for the frequency you selected and it would be good to go.
My next test with this antenna is to try tuning it to a WSPR frequency and comparing spots it receives to my other antennas. I suspect this it where it will shine.
Dear readers, it’s been a hot minute since I’ve had time to activate POTA and write about it, and today I tried to activate a park, but a combination of equipment issues and nobody responding to my calls ended my activation. Anyways … when life gives you lemons you make lemonade, and accordingly the activation article is now a radio review article instead! <grin>
That radio is the HF Signals zBitx. An SDR radio, it was spoken about at 2024 Four Days In May and it opened up for orders on December 25 2024 – a Christmas present, if you will. Thomas and I both jumped on the ordering queue (two numbers apart, no less) as well as 248 others around the world. I thought to myself “an all-mode 80-10m QRP radio with a waterfall and weighing under 1 pound for under $200USD shipped? SIGN ME UP!” and pressed the order button. Honestly I thought about it for less than 45 seconds once I read the specs. I also thought to myself that it was an “experimenter’s radio” and not a fully finished product, meaning you can tweak it if you wish to dig into the bowels of the code on the built-in Raspberry Pi.
The 250 original orders were snapped up in two days and then the purchase button was turned off on the website. There were some shipping delays from the original date, as HF Signals discovered the Chinese New Year holiday of 3 weeks where, it seems, everything is shut down. I also discovered this with the Morse Tutor Kits my buddy and I sell, and we couldn’t ship product for a month as we could not get parts.

The radio arrived on March 31, about 4 weeks beyond the original estimate, and I was excited to open it up. I mean, who doesn’t like new radio day after all? I was so excited that I did an unboxing and first look video on YouTube and showed off a few quick things about the radio. TOP SECRET – it took me 5 takes to shoot, so it wasn’t quite a first look!
The radio promises much and delivers a lot. It transmits on 80 through 10 meters at around 5 watts driven by a pair of 18650 cells, or your 6 to 9V four amp power supply. It has two microprocessors, one is a Raspberry Pi Zero W and one is a Pi Pico to drive the display. It has integrated AM, SSB, CW, FT8, touch screen, built-in electret mic, built in CW keyer and keyboard, and weighing just 460g / 1 pound including the batteries. This radio seriously has lots to offerespecially at the price point.

You must be made aware that I was really excited to get this radio. It has a history of many other Bitx radios before it. But I’m also aware that there’s the old axiom about “too good to be true” so I tempered my expectations. You must also be made aware that I really want this radio to work as its small form factor, low cost and integrated waterfall make it exciting an exciting prospect in my limited fleet of QRP rigs. And, for the record, I have nowhere near the QRP rig count that our gracious host has, nor are they individually named.
Besides all of that, it is the only HF radio I plan to pack for Hamvention 2025 so it’s gotta be right for that trip.
I love living in the state of Georgia. The state contains diverse natural spaces – mountains and valleys in the north, rolling hills and forests in the middle, and a plain extending to the coast with wetlands, marshes, and forests.

The Georgia State Parks on the Air event celebrates and draws attention to state parks scattered throughout these spaces. For this year’s event (April 5th and 6th), I signed up to activate George L. Smith State Park (US-2179), a park located a little over an hour from my home. I’ve activated this park several times in the past – for POTA as well as the K2D special event.
To do something different and to qualify for the hike-in bonus (100 points) for the event, I planned to hike the Deer Run Trail. This trail runs past the historic mill on site and through a wooded area on the southeast corner of the park. To qualify for the bonus, I had to hike at least 1 mile from my vehicle so I walked a section of the outer loop trail.

The hike was pleasant. Daisy and I walked through a forested area bordered by cypress bottomlands and farmland. Several benches along the path offered hikers a quiet place to relax. I was surprised by how many people we encountered.

We finally reached the junction of the loop and .7 mile trail, the latter having a power line running along it. Here was another bench set admist a mixture of pines and hardwoods. A tall pine directly across from the bench had a branch about 30 feet high, just perfect for the dipole antenna I brought, that is if I could reach it.

I removed my throw bag, arbor line, and throw weight, and tossed the line to see how close I could come to that branch. My line and weight ran over a broken branch forming a notch about 10 feet lower. I tugged to remove them and stared in amazement when the line abruptly broke free and fell at my feet…WITHOUT the weight attached. Oh crap! I was so gung-ho to nail that branch that I forgot to securely tie the weight to the line. (doh!)
my throw weight lodged in the notch
I stared in amazement, my mind slowly processing my situation. I did not bring an additional weight because I stopped carrying it since I never needed it (until now that is) and wanted to travel light for today’s hike. Shoot! Now what?
I spent the next 15 minutes trying to find a branch long enough to reach that spot as well as throw sticks at the weight. Nothing came close to dislodging it.
Well, I could just throw in the towel. But POTA Babes don’t give up that easily. I had an obligation to the event as I signed up to activate this park and hunters would be looking for me.
The only items in my pack I could attach to the arbor line and throw were an insect repellant bottle and my Nalgene water bottle. The insect repellant bottle I rejected because of its spray trigger which could definitely get stuck on a branch. But the Nalgene bottle might work. Daisy and I drank some water to lighten it. I tied the arbor line to the lid, found a branch about 15 feet up in the air, and tossed the bottle. Would this even work?
Nalgene bottle
It did! I know you antenna purists out there are shuddering. However, I figured a lower antenna was better than no antenna at this point. I brought two antennas with me for this activation: the Tufteln EFRW and a home-brew linked dipole I built roughly three years ago. A dipole is an amazing antenna, even if homebrewed. I figured my signal needed all the help it could get with the lower height and power lines nearby so I chose to use the dipole.
homebrew linked dipole antenna (40-30-20 meters)
Daisy and I settled across the trail in the understory to shade ourselves from the sun. One leg of the dipole ran across the hiking trail. To give the antenna as much help as I could, I secured both ends of the dipole roughly 6 feet up in foliage. Where it crossed the trail, it was high enough anyone would pass easily underneath it.
I took a breath, pressed the ATU button to activate the internal antenna tuner, cleared a frequency, and began calling CQ. I had no idea what to expect. Continue reading The POTA Babe Loses Weight→
As promised, here’s Part 2 of my extended HRWBOTA activation report from March 16, 2025!
(US-6856)
As I mentioned in Part 1 of this activation, I’d planned to operate for the full four-hour window of the March 16th Ham Radio Workbenches On The Air (HRWBOTA) event—a rare luxury for me. Most of my field activations typically last anywhere from 30 to maybe 90 minutes at most. So, sitting in one spot and operating for four full hours definitely stretched me a bit—but in a good way!
After two hours of non-stop CW with the Elecraft KX3, I took a brief break, swapped radios, and continued the activation with my Penntek TR-45L.
This portable rig is one of my favorite minimalist CW transceivers, and I thought it was a perfect fit for the second half of the HRWBOTA event. I used it to work 20, 30, and 40 meters in CW (in that order).
One nice bonus of using the TR-45L is that mine has a built-in Z-match ATU, which allowed me to easily find a match on 30 meters, even though the Spooltenna EFHW isn’t resonant on that band. The antenna was the same excellent 40-meter EFHW prototype from Rob (KO4HUI) that I featured in Part 1.
The only other minor change during this segment of the activation was behind the camera. Since I was filming in real-time for four straight hours, I had to pause at one point to connect my action camera to a portable battery pack which then limited my ability to use wireless microphones with wind screens. The gusty wind will be more noticeable in this portion of the activation video as a result—but, hey, it’s all part of the field experience!
Now, let’s dive into Part 2 of the gear and activation details…

As I mentioned in Part 1, this was a longer activation, and since I needed to submit electronic logs to HRWBOTA admin Mark (N6MTS), I skipped paper logging—a true rarity for me.
Instead, I logged directly into AC Log on my Microsoft Surface Go, just as I would during Field Day.
Check out the following announcement posted to the QRP-L discussion group by Wayne (N6KR) at Elecraft:

Did you know that magnetic north changes over time? And with that, magnetic declination changes over time! The link below is from the organization Alpine Savvy. Apparently, both have change dramatically.
Their website has a chart showing the change at Portland Oregon. It illustrates a dramatic change since 1900 to today, from 14° East to 22° East (currently), a full 8° difference over time.
Bear in mind, magnetic declination has a greater, more exaggerated variance and effect closer to the equator.
So what does it mean for the Ham rotating a large beam? Everything. Everything should be based on current data, specific for their location. It matters.
Many of the online references, even those at the USGS website are incorrect. Printed maps, topographic maps, are often incorrect.
Accordingly, you’ll need to orient your Azimuth map, and your antenna orientation! In my case, 12° 52′ East in Boise… Not 15° East as shown on USGS references.
It may not seem as important in HF field operations, given many field operators utilize wire antennas and therefore antennas orientation is less impacted by precise magnetic declination. But you need to understand these changes, in declination and magnetic north are, in some way, connected to the Sun and its influence on radio propagation, and the earth’s geomagnetic fields.
As an example… In WW2, the US Navy torpedoes often failed to detonate properly due to their magnetic proximity fuse detonators. The problem: They were not properly calibrated to their respective lat/long declinations. A simple oversight, or a misunderstanding with profound implications. Its costs were incalculable and directly affected the war effort.
