I look forward to all your videos and am enjoying how you use the Elecraft AX-1 in the field.
I have built the “WD-PT-PB” attachment for my AX-1 antenna.
That is, it is for Windy Day-Picnic Table-Park Bench use. It can be set up horizontally or vertically on the edge of a picnic table or at any angle on the back of a park bench and is a secure attachment for the AX-1 off the radio.
[I] bought the bolts straight and put them thru a random C clamp secured with a nut or wing nut and then bent one in my vise. Loosen the wing nut and angle the bolt any way I want and tighten the wing nut.
The pictures show it better than paragraphs of a description.

That’s brilliant, Jim! I love how versatile the clamp is and that it even fits in your Maxpedition pouch! No doubt, it’ll help the AX1 (or AX2, or any similar antenna) survive the windiest of deployments.
If you’ve been following QRPer.com and my YouTube channel for long, you’ll notice that I typically post two field reports with videos per week when my free time allows. Each report takes about four hours to produce along with a video. I’ve currently got a small backlog of videos I need to post, so in order to squeeze them into my schedule, I’m going to use a slightly more abbreviated field report format: a “postcard” format!
My Postcard Field Reports will still be information-packed, just slightly more concise and distilled than my average field report. I’ll primarily post these for sites I visit frequently.
Speaking of which….
Lake James State Park (K-2739)
Thursday, February 2, 2023, was a rainy, dreary day so the perfect time to play a little POTA, right? I made time in my morning to visit Lake James State Park (K-2739).
When I arrived at the Catawba River Access, the parking lot was empty. Not too surprising considering it was a Thursday morning on a chilly, rainy day.
During the months of January and February 2023, I’ve given my Elecraft AX1 a thorough workout. As I mentioned in a previous post, I thought it might be fun to take the AX1 out on a good 30 days worth of activations.
Turns out, I’ve had such brief windows of opportunity to play radio recently, the AX1 and now AX2 have been valuable tools in my field kit. They are, no doubt, the quickest-to-deploy and most portable antennas in my collection.
The Elecraft AX2 paired with the KX2.
If I only have a 20 minute window to squeeze in a quick park activation, the AX1 and AX2 make a valid POTA activation–with 10 logged contacts– a reality.
I originally purchased my Elecraft AX1 in the spring of 2020 and have used it extensively since then. In January 2023, I finally caved in and purchased the most recent addition to the AX family, the mono-band AX2.
Elecraft AX1 vs. AX2
Since I’ve been publishing numerous field reports recently using the AX1 (with more to come) and since Elecraft has included both the AX1 and AX2 in their February 2023 Specials, I’ve received questions from readers asking:
“Should I buy an AX1 or AX2–?”
and“If so, which one should I buy? What are the differences?”
At first, I simply pointed readers to the concise comparison guide that Elecraft publishes on their website (linked below).
I realize, though, that there are characteristics of each antenna that you might only discover after actually using them in the field.
I decided to make am unedited video–based on a few notes–not only describing the differences and similarities of the AX1 and AX2, but also if either would potentially benefit you as a field operator or traveler.
One quick note about resonance…
One point I touch on in the video is that both the AX1 and AX2 antennas are designed to be mostly resonant on 20 meters.
Small verticals like the AX1 and AX2, that use coils to electrically “lengthen” the antenna, have a higher Q than, say, a large aperture quarter or half wave antenna. In practical terms, this means that the window of resonance is narrow and more fickle than, for example, an end-fed half-wave.
A lot of factors can affect the SWR on higher-Q antennas like the AX1/AX2 including:
the type of terrain,
height off the ground,
length of counterpoise,
configuration of counterpoise,
and, most notably, the operator’s own body capacitance.
You may find that the AX2, for example, is natively resonant on 20 meters at one location, but isn’t at another location. This is quite normal. It’s also the reason why Elecraft states that both antennas are designed to be used with an ATU.
If you are pairing the AX1 or AX2 with a radio that doesn’t have an ATU (or you can’t use an external one), then you might consider making a simple capacity hat. Check out this field report and video where I paired the AX1 with the IC-705 and used a capacity hat to sort out the SWR.

Last year (May, 2022), Xiegu announced a new compact field radio that would be added to their line of transceivers: the Xiegu G106.
As I was capping off my summer in Canada (August, 2022), Radioddity started shipping the G106. Radioddity had me on their list of folks to send a loaner G106 to, but I didn’t have time to even look at the radio I was so busy upon my return, so didn’t immediately request it.
I did watch, however, K8MRD’s initial review and updated review of the G106. It was less than stellar [understatement alert!] but more than relevant to me because Mike shipped his second unit to me on behalf of Radioddity.
I connected that G106 to a dummy load, checked the transmitted signal, and it simply didn’t look very clean. It looked worse than it did when Mike checked it only a couple weeks prior.
I shared my results with Radioddity, told them I didn’t feel comfortable putting it on the air for testing in the field, and they asked to have that unit returned and checked out.
Updated G106
Fast-forward to January 2023 when I was once again contacted by Radioddity to see if I would like to field test an updated G106. I was happy to do so, in fact, because I was curious if the whole G106 experience had improved.
In the spirit of full disclosure: keep in mind that Radioddity is a Xiegu retailer/distributor–they are not the manufacturer nor are they owned by Xiegu. They are a sponsor of QRPer.com, but have no say in what I post nor any sort of editorial input. Indeed, this is always a condition of sponsorship from day one.
To Radioddity’s credit, some of my most critical reviews have been of products they’ve sent me on loan (especially the GSOC). They take criticism on the chin and keep on moving forward. This is why they are still a sponsor and I like working with them. They understand that I call it like it is and stand by what I publish.
This G106 has been sent to me on loan for a few weeks to review. I plan to take this unit on a number of activations and pair it with a variety of antennas and accessories.
Very early impressions
I will eventually publish a full review of the G106 (likely in The Spectrum Monitor magazine first) once I’ve put in a lot more field and shack hours with the G106. In the activation video, below, I do make a lot of comments about the radio–thinking out-loud–so if you’re considering purchasing the G106, you might at least listen to a few of my initial impressions.
I will say this: for a modern SDR-based transceiver, it’s pretty bare-bones. It lacks a number of features I assumed it might have despite the incredibly affordable $320 US price point:
No SWR meter
No Power meter
No CW or Voice message memories
No RF gain control
No AGC control
No dedicated headphone audio output
But, again, it has more features than many of the bare-bones CW-only QRP transceivers out there, so for the price perhaps expectations should simply be in check–?
Zebulon B. Vance Birthplace (K-6856)
On Tuesday, January 31, 2023, I took the G106 on its maiden POTA activation to K-6856.
The G106 doesn’t have a built-in ATU (which I would never expect at this price point) so I decided to pair it with a resonant antenna. Since it was a very rainy day and the area/ground where I tend to deploy my wire antennas at Vance was squishy and soft, I opted to deploy my Chelegance MC-750 next to the picnic shelter.

Antenna tuning on Superb Owl Sunday
by Vince (VE6LK)
While many in North America were watching a number of Superb Owls move a pigskin around a playing field, I was off to play radio, successfully, for the first time in weeks. This is part of my goal to activate 200 CW POTA contacts per month this year.
During recent visit to Vancouver attempting to operate from within my hotel room, and utilizing the Edisonian Approach, I was shown -more than once- what did not work. This will no doubt be a discussion point on an upcoming Ham Radio Workbench Podcast. I was therefore in very bad need to get back on the air while operating portable. I was close to feeling twitchy and in need of some POTAXXIA (Hyperradio Moduzolium). A plan was needed!
My goals were to trim out a new-to-me EFHW (thanks VE6VID), and make some contacts while operating outdoors. The weather was forecast for 50F, but turned out to be unexpectedly windy. Also, when the wind comes off the Canadian Rockies in Southern Alberta, it cools the area where I’d be (downwind), so a choice of operating location was key. I love going to this park for the moment that you drive west along Highway 533 and come around the corner as you see here in this short video.
Chain Lakes Provincial Park (VE-1168) is located between the Porcupine Hills and the Rockies on Highway 22 (locally known as the Cowboy Trail) in Southern Alberta, about 90 minutes south of Calgary. It’s especially gorgeous at sunrise and sunsets. A campground, lake with boat launch and a day use area all adorn this park created for water management with an earthen dam. While it is in a valley, the wind can be howling on some days. On this day it would prove to be just above a nuisance, sort of like mosquitos in the spring -you can live with the nuisance, but only for so long before you blow a proverbial gasket.
I located a lovely spot below the dam -and the majority of the wind- however it was outside of cellular range. I’d need to rely on the Reverse Beacon Network to spot me. The RBN will, in turn, post your spot to the POTA website once it hears you if you schedule your activation in advance.

The place I found would only be more perfect were it warmer than 45F and without wind. A babbling brook was by the picnic table, and a nearby footbridge had built-in supports for my painter’s pole that would serve as the far end support. I’m pretty sure that they weren’t intended for me specifically, but they were the perfect size to simply slide the pole into place and hold it firmly. By luck I parked the truck the correct distance away with it’s drive-on mount and 28′ Fibreglass Flagpole from Flagpoles-To-Go via Amazon. Continue reading VE6LK: Antenna tuning on Superb Owl Sunday→
On Friday, January 27, 2023, I dropped off one of my daughters at the library for a creative writing session.
Hazel was along for the ride, so we decided to hike on the nearby Mountains To Sea Trail (MST) while my daughter was in the meeting.
During the hike, I realized that I should have taken my field radio pack along because it would have been so easy to activate both the MST and Blue Ridge Parkway as a two-fer.
Instead, Hazel and I enjoyed our hike and got back to the car with about 35 minutes or so to do an activation–including set-up, on-air time, and pack-up. That would leave me just enough time to pick up my daughter at the library before they closed for the day.
Challenge accepted!
Because I had been using the Elecraft KX2 and AX1 recently, I had both packed in my Spec-Ops EDC backpack. In theory–even filming a video at the same time–I knew I could probably fit in a whole activation with 25 minutes on the air. I only needed 10 contacts, and I’ve never been in a situation where the AX1 couldn’t achieve that goal.

The VK160 Antenna packed on its Winder/Feedpoint for storage, transport, and deployment.
Building and Testing the VK160 Antenna
by Brian (K3ES)
The ability to set and achieve long- and short-term goals keeps me interested and active in the Parks on the Air (POTA) program. Often these goals are associated with POTA awards. Currently, I am working slowly to complete the activator version of the James F. LaPorta N1CC award, which requires an activator to make QSOs on 10 amateur bands from 10 different parks. With my operating style, I have found it achievable to make QSOs on the 9 available HF bands (80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, and 10m), and this has become easier with the rising solar cycle. I have completed QSOs on non-HF bands using 2m and 70cm simplex. The other options to pick up 10th band QSOs include the 6m band and the 160m band.
I have found it difficult to make unscheduled POTA contacts on 2m and 70cm, and scheduled contacts can be difficult to arrange in parks that are remote from population centers. I have built a 6m antenna, but contacts are seasonal (and for me very elusive). So I started looking for a way to add 160m capability to my portable station. Ultimately that resulted in homebrewing a new antenna that I now call the VK160, and here is its story.
Objective
I needed a field-deployable 160m antenna. My operating style requires that the antenna system be both light and compact. QRP power levels are sufficient for my purposes. I am very comfortable deploying wire antennas in the Pennsylvania woods, and QRP wire antennas can be both light and compact. I have found that end-fed antennas are simpler to deploy in the field, because they can be configured as an inverted V or as a sloper, using only one point of support.
An end-fed half wave (EFHW) antenna would be naturally resonant, but would need to be over 250 ft (76m) long. A wire antenna of that length would be challenging to deploy, even in more open areas. So, I decided to pursue a 9:1 unun-based end-fed “random wire” (EFRW) antenna. In fact, I have two commercial EFRW antennas available, but have never been successful in tuning them for 160m using the ZM-2 tuner in my field kit. So, I concluded (probably incorrectly, but more on that later) that I needed to build a 9:1 random wire antenna with a longer radiating element than the 71 ft wire built into my largest existing EFRW. I also wanted to build this antenna myself, using available components, so that it would be both inexpensive and customized to my needs.
I broke the task into four parts:
First, I needed to build a 9:1 unun suitable for use at QRP power levels. The 9:1 unun is an autotransformer that reduces antenna feedpoint impedance by a factor of 9, hopefully a level that a wide-range tuner can match to the 50 ohm transceiver impedance.
Second, I had to design and build mechanical elements of the antenna system, incorporating the electrical components needed for the feedpoint.
Third, I needed to select a suitable non-resonant wire length for the radiator.
Finally, I needed to deploy and test the finished antenna on the air. If successful, testing would culminate in completing an on-air QSO with the antenna being driven at 5 watts or less.
Building the 9:1 Unun
While I have built successful 49:1 ununs as the basis for EFHW antennas, I had no experience building 9:1 ununs. Accordingly, I started with the ARRL Antenna Book, then a web search. VK6YSF’s excellent web page provided very detailed instructions for 9:1 unun construction. His 9:1 Unun design was based on a FT140-43 toroid wrapped with heavy gauge magnet wire, with design power rating around 100 watts. My application was focused on 10 watts maximum, and I wanted a lighter-weight solution to the unun design.
Looking at the components I had available, I found FT50-43 toroids and 24 AWG magnet wire in my inventory. I had used those during construction of successful 49:1 EFHW antennas. The VK6YSF design, built with the smaller toroids and lighter magnet wire, seemed to be a good (and cheap) starting point.
The “50” portion of the FT50-43 toroid designation specifies its 0.50 inch (1.27 cm) outside diameter. The “43” portion designates nickel/zinc composition that is suitable for high frequency inductive applications.
The next problem that presented itself was a problem with translating the winding technique to smaller wire and a smaller toroid. Put simply, my fingers do not have the dexterity to wrap three parallel 24 AWG wires around a ½ inch OD toroid without getting them crossed, twisted, or worse. So, why not twist the three conductors from the start, and wrap the toroid with “trifilar” windings? It would be simple enough to identify the mating wire ends after wrapping, just with a set of continuity tests. That would facilitate proper connection of the wires to yield the final auto-transformer configuration.
FT50-43 toroid with three-10 inch (25.4 cm) segments of 24 AWG enameled magnet wire staged for construction of the 9:1 unun.
I posed the “trifilar” winding question to my friends over on the QRPer.net discussion board. Nobody identified a significant flaw with the proposed method, but neither did anyone have experience that would assure success. So, I decided to use the “trifilar” winding technique to construct my 9:1 unun, with the full recognition that its success would be uncertain, and only proven by testing the finished product.

As I mentioned in my previous field report, on Saturday, January 21, 2023, I had just enough time to activate two parks in short order on the way back to my QTH
I thought it might be fun to perform both of these activations with the Elecraft KX2 and AX1 combo because they’re so speedy to deploy.
Once again, I wanted to show the whole KX2/AX1 set-up and pack-up process in my activation video.
Lake James State Park (K-2739)
As I pulled into the Lake James Catawba River access, I discovered that there were few other guests there that day. I was expecting more people on a Saturday especially since the weather was so pleasant and South Mountains had been so busy earlier that morning.
Then again, the Catawba River access always has less visitors than the Paddy’s Creek area (which is really the main public access point for Lake James).
I pulled into a parking space, found one of the closest picnic tables, and set up the station in short order.
At South Mountains State Park, an hour earlier, I performed the entire activation on 20 meters. To shake things up a bit, I decided to perform the one at Lake James on 17 meters (note here that the AX1 only works on 20 and 17 meters unless you have the coil which adds 40 meters).

I also assume the 3Y0J team would need to create an account and submit their logs to the POTA system for LA-2524 hunters to get credit.
It would be pretty amazing to confirm LA-2524 because it’s doubtful anyone will activate Bouvet Island anytime soon after this current DXpedition team.
3Y0J
Bouvet Island (Source: 3Y0J Facebook Page)
Bouvet Island is one of the rarest DX entities on the planet: it’s number two on the DXCC Most Wanted list (at time of posting), second only to P5 (North Korea).
I don’t consider myself a DXer or contester, but many of my local ham radio friends are hard-core DXers.
I do have some DXing and Contesting exposure, though, because I typically attend and volunteer to help at the annual W4DXCC conference in Tennessee.
One of the things I’ve learned attending the W4DXCC conference is the incredible amount of energy and resources it takes to execute a DXpedition like 3Y0J. It takes many years of planning, lots of money, lots of permits, top-notch healthy operators, and, frankly, lots of good old fashioned luck.
Steve Hass posted this image on Facebook and noted, “3Y0J camp location on the hill.”
The 3Y0J team had difficulty (understatement) setting up on the island due to weather conditions. Here’s one of their latest updates detailing how they landed via their Facebook page:
3Y0J Bouvet Island 2023 Update [February 7, 2023]
Interview with 3Y0J Team Co-Leader Ken LA7GIA.
“Everything is OK in the camp. The guys are good. We have a few antennas up. Running some pileups and preparing for the storm which will arrive in a few hours and last until Thursday. The boat will pull away from the island a bit. The antennas and camp are being secured. The winds are expected to be 60 knots. 9 members will stay in the camp during the storm. They will try to run two bands this evening and tomorrow. They will take down one antenna. They will run 30m and 17m using the Spider Pole on 17 and the aluminum DX Engineering antenna on 30m.
The operation has proved to be extremely difficult. The most extreme expedition I’ve been to. Setting up the camp has been a lot of work.
We will focus on CW and phone but there will be FT8. We have just discussed this today. We are running low power, only 100w. We have no amplifiers. We have three antennas set up. We are considering setting up 20m as well. So we will have 30, 20, 17, 15.
The beach landings were accomplished by holding onto a line attached to a buoy and floating 15 meters to the beach in our survival suits. This is quite extreme. We float in all the equipment as well. Then carry the equipment 800 feet up to the camp. We have videos of this. We spent a few days to set up the antennas and tent then prepared for the storm that is coming.
Everybody is in good shape. It’s quite hard to stay here. A lot of wind, but today was a quiet, nice, and sunny day . This will change, and there will be a lot of rain. The day we arrived was a lot of wind and rain. Activating Bouvet is not like activating an island in the Caribbean. It is really windy, cold, and exhausting to bring equipment up here. It’s a different DXpedition than we thought we should do. It’s a challenge, but we hope we can stay on the island for some more days.
Regarding dupes, please only call us if you hear us. We have very good receive here on [Bouvet] Island. We do not have any facility to upload the log on the island. We are saving on fuel and connection for this. When we get back to the vessel, we will likely upload. We don’t know when the first upload will be. Going to Marama is very time consuming project because of the procedure involved. (Ken describes it.) The first upload may be in the weekend. Again, if you don’t hear us, don’t call us.
Nothing more to report. Hopefully people understand the complexity of this operation. Hopefully we will be able to stay another 7 to 10 days. We are working on plans for how to continue the operation despite the difficult weather conditions here at Bouvet.”
73, Steve N2AJ Media Officer & NA East Coast Pilot 3Y0J Bouvet Island 2023 DXpedition
They’re hunkered down in their tent and doing all they can to be on the air during this bout of rough weather.
Let’s hope they can move more gear, operators, and antennas to the island in the coming days.
Logging 3Y0J
One of the 3Y0J crew on Bouvet Island. (Source: 3Y0J Facebook Page)
I’m going to give it my best effort to log 3Y0J.
It’s not going to be a cake walk.
For one thing, this may very well be the last time Bouvet is activated by people (boots on the ground) in our lifetimes. I think you’ll find that DXpeditions like this–those that are very high risk–will soon be activated remotely. A remote, fully-self contained station will be set up on-site and most of the contacts will be made using remote ops in the boat or from across the world from the comfort of their own QTH.
As mentioned in the announcement above, the 3Y0J team hope to be on the air for a bit more than a week (7-10 days from February 7). DXpeditions like this are often cut short when weather forecasts indicate difficulty getting people back to the ship in one piece. If you feel you must log 3Y0J, I wouldn’t wait a few days for the pileups to subside.
Speaking of pileups, the 3Y0J pileups are some of the largest I’ve ever experienced. It will take skill to log 3Y0J if you don’t have a blowtorch station.
And then there are the QRMers
Gjermund LB5GI on watch duty onboard Marama (Via the 3Y0J Facebook Page)
This is the side of amateur radio none of us like to see or hear. Frankly, I don’t even like mentioning it, but I think it’s important for newcomers to understand what they’re experiencing as they try to work 3Y0J (in split mode always) and also understand that there are some deceptive stations out there.
This being such a highly-anticipated DXpedition with so many folks tuned to 3Y0J calling frequencies, it gives an extremely large audience for jammers and QRMers to cause a maximum amount of disruption.
I hesitate to call these folks “LIDs” because the origins of this term refer to inexperienced ops who may simply be making mistakes out of inexperience or ignorance. With any DXpedition, there are always newbies who don’t understand split operation and call on the TX frequency. That’s to be expected and, frankly, I’m forgiving about that. Once a good op makes the mistake, they’re unlikely to ever do it again.
Sadly, the intensity of intentional jammers–those deliberately causing harmful interference to 3Y0J’s operations–is just insane. This is happening on both SSB and CW frequencies. I’m sure they’ll try to interfere with FT8 as well.
On top of that, there are a number of “pirates” posing as 3Y0J and spotting themselves to the DX cluster. If you’ve worked a 3Y0J station and felt it wasn’t too difficult because the signal was strong and there wasn’t a lot of competition, then you’ve likely worked a pirate. Double check for a confirmation after the 3Y0J team does a log upload. Also, check for announced frequencies on the 3Y0J Facebook page.
It’s a bit of a circus and it’ll likely take all of your skill to work 3Y0J. I think FT8 (in F/H mode) will turn out to be the path of least interference to logging Bouvet.
Video interview with 3Y0J Team Co-Leader Erwann (LB1QI) earlier today
Have you logged Bouvet?
Please comment when/if you confirm Bouvet! I’m very curious if they’ll submit their logs via POTA to give hunters credit for this rarest of parks!

A shelter for Winter Field Day operations in a field
Field Report: Winter Field Day with a New Antenna
Winter Field Day (WFD) 2022 found me operating indoors, despite my best intentions to get out in the field. I was recovering from a bad cold, and did not want to risk having complications arise from sitting out in the cold and damp. So for WFD 2023, outdoor time with my radio was a must. I wanted to operate a 1-Oscar station, and to do that I had to set up more than 500 feet from my home QTH. So a site next to the pond in our back field, about 800 feet from the house, became my WFD shack.
I started planning and collecting kit for the operation in mid-January, with the long term forecast hinting at near-freezing temperatures with the potential for rain or snow. Let me introduce you to my WFD station.
Shelter
A shelter was needed to keep out rain and snow, and to provide a barrier against the winds whipping across the adjacent field. A few poles lashed together, and steadied by stakes, provided the frame to support the shelter. With a poly tarp secured to this frame, the resulting a-frame shelter, while not completely enclosed, did provide effective weather protection for both operator and equipment. There was about 3 inches of snow on the ground when I set up the shelter, and I was able to pile some of it along the bottom edge of the tarp to keep the wind from getting under it.
A-frame shelter constructed of a poly tarp stretched over a frame of poles
Antenna
I know that when setting up a station, the antenna is not generally the first thought, but I had recently finished building a homebrew 9:1 random wire antenna with a 144 ft radiating wire, and I wanted to test it out. There are better ways to put a new antenna on the air, but the opportunity was a good one. Besides, I had backup antennas that could be quickly substituted if the need arose. In the event, things worked well, and the antenna proved agile and capable on all activated bands. I particularly wanted to see if it would tune on the 160m band. More on that later.
The feedpoint of the 9:1 random wire antenna is built into a wire winder to support transport, deployment, and recovery for field use. The RF functional components include a female BNC connector, a 9:1 unun, and miniature banana jacks for connecting the radiator and counterpoise wires. There is no wire on the winder, because a corner was broken off during WFD deployment, and a mechanical repair is needed. (Click to enlarge)The 9:1 unun is mounted near the BNC connector, and is electrically connected to a one miniature banana jack for the radiator and another for the counterpoise. The unun and wiring are covered with hot melt glue to provide mechanical integrity and protection from the weather.
Radio
The goal of trying the antenna on 160m left me with only one choice for a radio. I would use the Lab599 TX-500 Discovery, because it is the only transceiver among my field rigs that is capable of operating on the 160m band. Since a tuner is required, I paired it with an LDG Z-11Pro II, a wide-range autotuner. I also included a Monitor Sensors Power and SWR Meter in the feed line to help assure that I was legitimately running less than 5 watts to qualify for the QRP power multiplier.
