If you’ve been a QRPer.com reader or subscriber to my YouTube channel for long, you’ll know I’m quite the fan of super-compact, low-profile antennas like the Elecraft AX1 and AX2.
Although AX antennas are certainly a compromise in terms of performance, I find them surprisingly effective for on-the-air programs like SOTA, POTA, and WWFF. While they’re not high-gain, they’re also far from the “dummy load” some make them out to be. In fact, the best DX I’ve ever worked in the field was with my Elecraft AX2 and just 5 watts of power—check out the field report.
It covers 30 through 10 meters and uses a 4-position band selector plug, which I personally find more rugged than the AX1’s band switch. Like its siblings, the AX3 is designed to pair with an ATU, but unlike the AX1/AX2, it doesn’t need to physically mount to the transceiver—so it’s compatible with virtually any rig and tuner combo. The AX3 also supports up to 30 watts.
Despite the added versatility, the AX3 still packs incredibly small: the whip, base, and tripod legs collapse to just 6 inches, yet the whip extends to 45 inches in the field. The side-mounted BNC connector avoids awkward cable bends or adapters.
In the spirit of full disclosure, I’m in the testing group for the Elecraft KH1 and, as such, I was aware the new AX3 was on the horizon, but I had not yet tested it in the field until I ordered one and it was delivered on Tuesday, April 29, 2025.
From Unboxing to Activation
Since Hurricane Helene wiped out our local post office, my buddy Vlado (N3CZ) has kindly allowed me to have parcels delivered to his house. When he told me that “a small box” had arrived from Elecraft, I knew exactly what it was.
I had an errand in town that afternoon, so I swung by Vlado’s, picked up the package, and then stopped at the Blue Ridge Parkway Folk Art Center to perform the AX3’s debut activation.
Of course, I packed my Elecraft KX2, thinking it would only be right to pair the AX3 with an Elecraft radio for its first outing!
In my activation video (below), you’ll see that assembling the AX3 was incredibly simple right out of the box. I ordered the full AX3 package, which includes the antenna, mini banana plug, counterpoise wire, tripod legs, BNC-to-BNC cable assembly, and a small nylon storage bag.
I attached the tripod legs, screwed on the whip antenna, clipped the counterpoise to the ground lug, and connected the BNC cable. In less than a minute, the antenna was fully deployed and ready to go!

My new Elecraft AX3 antenna arrived in the mail. The weather when it arrived was 73° F and sunny with a slight breeze. Space weather was calm. It seemed like the perfect recipe for a POTA expedition to the unofficial antenna testing range at Silver Sands State Park (US-1716) here in Connecticut on the Northern shoreline of Long Island Sound to try out the AX3. Given that this antenna is specifically designed to be light and portable, I chose my Elecraft KX2 to pair it with, which is also light and portable.

The AX3 operates on six bands. Out of the box, it can do 30,20,17,15,12 and 10 meters. With the optional AXE1 adapter, you can add 40 meters as well. Elecraft says an ATU is required, which I have built into my KX2. I tested using FT8 on 30/20/17 & 15 meters, the four positions labeled on the front “jumper block.” Using FT8, I was able to use the PSKreporter.info website to get a sense of where my signals were being received. This antenna is capable of handling 30 watts, which is amazing for its size. I ran 10 watts from the KX2.
Unlike the AX1, which needs something to hold it in place such as a tripod or the optional bipod, the AX3 comes with three legs to turn the base into a tripod.
AX3 integrated Tripod
At the park, I tried using the legs which lasted all of 30 seconds before the Long Island Sound breeze blew it right over on its side. Anticipating that it might be too breezy down at the shoreline, I brought a slightly heavier tripod along. The good news is that the bottom of the antenna is tapped with a ¼-20 hole to connect to any standard camera tripod. The heavier tripod did the trick.
Elecraft KX2 with new AX3 antenna
I used a three foot piece of coax as recommended and I had no problem with RFI into the radio or the computer. The KX2 was able to tune to 1.0:1 SWR on all bands except for 17 meters, which was right around 2.0:1. I should note that I had the 13’ counterpoise laying on the ground for this test.
KX2 1.0:1 SWR on 20 meters
I began on 20 meters and in 20 minutes, I had the 10 QSO’s needed to activate the park.

Next I QSY’d up to 17 meters.
PSKreporter.info spots on 17 meters
Here, I had plenty of spots, yet I struggled to get two in the log before I gave up and QSY’d to 15 meters. Changing frequency is as simple as pulling the jumper block out and moving the arrow to the correct frequency.

Thankfully, 15 was open and my first QSO was with a station in Ukraine and my second was in California.

I made contacts on 20, 17 and 15 meters. Could I manage something on 30? I tried but to no avail. I was spotted by stations on PSKreporter, but after calling for some time, I figured that midday in Connecticut was just not the best time for that band. Before I packed up for the day, I went back to 17 meters which was definitely better than earlier and I logged three more for a total of five on the band.
PSKReporter spots on 15 meters using the AX3 antenna
I took the opportunity to go back to Silver Sands a few days later to try the antenna on 12 and 10 meters, which I did not do on the first trip out. I also wanted to see how elevating the counterpoise might affect the performance. It was downright windy, so I brought along a camera tripod this time to provide more stability. Obviously, the extra weight carrying a full size tripod wouldn’t be ideal for a SOTA activation, but for my test, I brought it along.
AX3 on camera tripod
The high band propagation was miserable when I went out, I was wondering if I’d be able to make any contacts at all. I was pleased to see that elevating the counterpoise allowed 17 meters to easily match to the antenna with a 1.0:1 SWR. I then tried 15, 12 and 10 meters which also tuned right up and I made contacts on all bands. 10 and 12 meters were open to my south. I made QSO’s with Belize, Mexico, Ecuador, the Dominican Republic and Puerto Rico.

The AX3 did not disappoint.
Making QSO’s from California to the Ukraine and down into South America while sitting at a picnic table in a park in Connecticut with just 10 watts using such a small antenna is simply amazing to me. I like the AX1, which I used primarily on 20 meters. Having the multi-band flexibility of the AX3 is very nice, especially now that the upper bands are active, and it provides more flexibility for operating portable and being able to change bands on the spot to adapt to the ever changing band conditions.
On the activator side of things, Parks On The Air is often a solitary pursuit for me. I typically squeeze in activations as my schedule allows—usually at random times during the day in parks that happen to be along my daily route.
But every once in a while, the stars align and I get the chance to activate with a friend. When that happens, it only amplifies the radio fun. Saturday, March 22, 2025, was one of those special days. My dear friend—and frequent field report contributor—Brian (K3ES), along with his amazing wife and photographer, Becky, stopped by Asheville en route to the Outer Banks.
I was so happy everything came together and we were able to meet up for a short, relaxed, and thoroughly enjoyable activation.
Two-Fer Time!
When out-of-state activators come through the area, I always try to offer them the option of a two-fer—activating two parks at once—to maximize their POTA opportunities. I’m not sure Brian had strong feelings about this either way, but it was simply too easy to pair the Blue Ridge Parkway (US-3378) with the Mountains-to-Sea Trail (US-8313). Since we were meeting at the Folk Art Center, all it took was picking the right picnic table near the MST.
In my rush to leave the QTH that morning, I realized halfway down the driveway that I’d forgotten to pack my antenna. I could’ve turned around, but I knew Brian would have a few antenna options stowed in his field kit—and of course, he did!
He chose to deploy a homebrew end-fed random wire with a 29.5’ radiator and 17’ counterpoise. We paired it with my Elecraft K1 transceiver–a radio I knew Brian had never operated.
The only drawback of this particular picnic table is its proximity to the Mountains-to-Sea Trail. When deploying a wire antenna, you have to be careful not to obstruct the path for hikers. We positioned the wire in a near-vertical configuration above the table and kept the throw line tucked away on the opposite side from the trail.
We were also quite conspicuous—another reason I usually avoid this picnic table when activating solo. On a busy day, it’s not unusual to have a dozen people stop by to ask what you’re up to. It’s a great outreach opportunity, but a string of interruptions can make it difficult to complete exchanges—especially while sending CW. Sadly, my internal CPU isn’t optimized for multitasking!
Right to Left: Brian (K3ES) and Thomas (K4SWL)
But when there are two of you taking turns at the key, it works beautifully—one person can handle the questions while the other shows just how cool Morse code still is in the 21st century.
It was a fairly quiet day at the Folk Art Center, but one curious family did stop by to chat with us during Brian’s turn at the key—and I really enjoyed the interaction.

Xiegu G106 Report
by Philip (KA4KOE)
Recent developments and other drivers pushed me to purchase a Xiegu G106.
This radio has dropped significantly in price recently. I figured, “Why not?!” given the paltry sum Radioddity was asking.
I will not delve deeply into the technical aspects of this radio, as others have covered this subject in great detail. In my opinion, the G106 is a viable QRP radio and excels at CW and FT8. I also made contacts using SSB, but given the lack of speech processing, I found the effort, shall we say, challenging. The firmware on my particular radio is Version 1.3.
I checked the spectral purity using the panadapter on my Flex 6300. I realize the Flex is not a lab-quality instrument, but the serious spurs and other trash around the carrier, noted by others, on a 5-watt CW signal appear to be minimal now and compliant with current FCC regulations.
Some get all caught up in demanding the absolute best specifications, performance, looks, etc., or whatever you find important in your personal metrics for a radio. As an engineer, I approach this philosophy from a different mindset. Often, striving for those final few percentage points of improvement is only noticeable under the most stringent of band conditions. The situation is essentially a cost/benefits analysis. So, my personal rationale is “good enough.”
Indeed, the Xiegu G106 is “good enough” for QRP field activations, provided one also deploys a good antenna. Here’s an analogy: will a steel sledgehammer or solid gold one (ignore gold’s softness in this example), of the same mass, both do the same job? The answer is “yes.”
The only issue I have noted, as have others, is that the radio’s AGC recovery isn’t quite correct. Occasionally, the audio will “pop” when switching from transmit to receive. Hopefully, the G106 will improve if Xiegu issues firmware updates beyond Version 1.3. The radio doesn’t exhibit this annoying behavior every time one switches from TX to RX.
I recently activated US-2190, Magnolia Springs State Park, near Augusta, Georgia.
Band conditions degraded over the course of the day due to coronal holes present on the earthward-facing side of the sun. I did manage to make 25 CW and 8 SSB contacts on 40 and 20 meters using a sloping 40–10 meter N9SAB End Fed Half Wave, supported on one end from a 32’ carbon fiber pole. See the QSO map below:
Here’s my activation video:
Bottom line: I like the G106.
Thank you for your kind consideration and attention.

Gailey (WV2P) and Frank (NM9X), pictured above, also accompanied me on this activation.
Some time before Easter I noticed that I am close to 1000 QSOs at my favourite place at the “Kalte Feld”, a POTA and SOTA activation zone and would soon qualify for the POTA Kilo Award. I like the Kalte Feld for the quiet, spacious area with a hut that is vending traditional basic food and beverages – which in Germany usually means good beer and different sausage types (and other stuff – to be fair). I already wrote some articles about the history of the area and my activations.
The conditions at the activation zone are quite good. I have made 2 activations there with more than 100 QSOs (and many smaller), so I thought it should not be too difficult to complete the required QSOs in one day.
DAY 1
The weather for the Easter weekend was expected to be one of the first warm and sunny days this year. So, on Easter Sunday, I headed to the area to get the last missing 49 QSOs for my POTA Kilo Award. Easter hiking has a centuries long history in Germany. This and the nice weather made the area quite crowded. The close airfield for gliders was busy and the whole time while operating there they were in the air above.
The barbecue places and outdoor seating around the mountain hut were busy but happily the bench some meters away that I am normally using, was still available.
I wanted to start with an end-fed half-wave antenna for the 20m band, tied to a 10 meter (33 ft) fiberglass mast. This is a very easy and quick to deploy antenna and I like it, especially if there is not too much space for antennas with a larger footprint. Since it’s a straight vertical, it also has a higher chance for DX contacts – when the conditions allow that. The antenna is Open Hardware and you can find further details on GitHub.
The mast was tied to the bench and the antenna was raised. Besides the comfort, the possibility to tie a mast to it is the second reason why I am always looking for benches.
The conditions were far from being perfect, and it took me 40 minutes to get 18 CW QSOs on the 20-meter band. Switching to SSB wasn’t a big help either, and I soon gave up with only 3 additional SSB QSOs in the log.
I had brought another antenna with me that I wanted to try. The 10 meter (33 Ft) fiberglass mast also has the perfect height for a ¼ wave vertical on the 40-meter band. So I cut 5 wires to a length of about 10 meters (33 ft) and connected 4 of them together at one end with a cable lug and attached another cable lug to the vertical element.
I then used the basis of the JPC-7 antenna for the coax plug and for connecting the vertical element and the radials. There are a lot of articles and videos about ¼ wave vertical antennas. But the information is usually about either elevated and resonant radials or random length ground radials. I wanted to have resonant radials, but I could not be bothered with carrying all the stuff nearly 2 miles to a summit for elevating 4 x 10m (33 ft) wires, so I simply left them on the ground.
My idea was to try a full size vertical for the 40 meters band with resonant radials that still is portable and fits to my existing equipment.
The SWR was quite nice being close to 1.0 : 1 at the CW portion of the band, so I started operating.
The conditions were similarly difficult as on the 20-meter band. It took me 25 minutes for another 18 QSOs.
As it became increasingly cloudy, I checked on my mobile and saw that rain was approaching fast. Since I had roughly 2km or 1.5 miles descent ahead of me, I stopped abruptly with just 10 QSOs short of the POTA Kilo Award.
A bit disappointed, I called it a day.
DAY 2
I could not leave the missing 10 QSOs for long. The very next day, Easter Monday, was a public holiday in Germany. And as the weather started nice, I again made my way to the activation zone. Continue reading Experimenting My Way to the POTA Kilo Award→

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.
This bison had no problem napping in the middle of the Prairie Dog TownThis prairie chicken appreciated shade and water in the parking lot
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!

Elecraft K1 (four band version with optional ATU and internal AA battery pack)
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.

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.

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.

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…

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):

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.

A couple of weeks ago, Wayne Burdick of Elecraft announced the new Elecraft AX3 portable antenna, the latest addition to the AX line.
Despite the added versatility, the AX3 still packs incredibly small: the whip, base, and tripod legs collapse to just 6 inches, yet the whip extends to 45 inches in the field. The side-mounted BNC connector avoids awkward cable bends or adapters.
Since Hurricane Helene wiped out our local post office, my buddy Vlado (N3CZ) has kindly allowed me to have parcels delivered to his house. When he told me that “a small box” had arrived from Elecraft, I knew exactly what it was.
Of course, I packed my Elecraft KX2, thinking it would only be right to pair the AX3 with an Elecraft radio for its first outing!
I attached the tripod legs, screwed on the whip antenna, clipped the counterpoise to the ground lug, and connected the BNC cable. In less than a minute, the antenna was fully deployed and ready to go!

The first thing I did was make sure the band plug was set to 14 MHz, then pressed the ATU button to find a match on 20 meters. Continue reading From Box to POTA: First Activation with the New Elecraft AX3!
