Many thanks to HUAQIANG Gu (BD4LB) who shares the following information about his homemade L-Match. Note that BD4LB doesn’t speak English, and I don’t speak Chinese, so the following was machine-translated via Google Translate:
Homemade L-Match for Field Operating
by HUAQIANG Gu (BD4LB)
L-MATCH has a simple structure and is easy to make.
It is mainly composed of a coil and an adjustable capacitor.
The coil is made of copper wire with a diameter of 1.8mm, and the outer diameter of the coil is 50mm.
The capacitance of the thin film adjustable capacitor is 0pF–200pF.
When using, a balanced ground wire needs to be installed.
(Different bands, multiple quarter-wave length wires, and together. I use a row of wires. For example: two balanced ground wires 10 meters and 5 meters long, respectively 40 meters band and 20 meters band balanced ground wire.)
After many outdoor communications, I adjusted the end-fed antenna. The length of the radiator was 10 meters, which was appropriate.
One end of it is hung from the top of a 6-meter-long fiberglass fishing rod. On the other end, connect the red binding post of L-match.
Balance the ground wire and connect it to the black binding post. Spread it out on the ground.
The L-match is placed on the ground and connected to the HS1B or KVE60C antenna analyzer using a one meter long 50-3 coaxial cable. (This reduces the length and weight of the coaxial cable.)
When using an inverted V antenna, the length of the coaxial cable needs to be at least 8 meters.
My outdoor communication is mainly on the top of a hill in the park, or on the beach by the sea.
On the beach, there is plenty of space. In addition to setting up end-fed antennas, you can also set up inverted V antennas.
On the top of the mountain in the park, the space is limited, and it is difficult to deploy the 20-meter-long antenna oscillator. Only 10-meter end-fed antennas can be used.
After fixing the fishing rod, installing the antenna radiator and balanced ground wire, first connect the antenna analyzer KVE60C.
Use copper alligator clips to clip on the coil and adjust the adjustable capacitance to minimize the standing wave ratio of 7.023 MHz.
(Change different coil taps, adjust the adjustable capacitor, and try several times.)
I carry a compass to adjust the transmitting direction of the end-fed antenna. I won’t get lost.
The actual communication effect is quite good.
In the 40-meter band, it is suitable for short-distance communication within 800 kilometers.
In the 20-meter band, it is suitable for communication within 1000-2000 kilometers.
I was speaking with my buddy Joshua (N5FY) in mid September. He’d recently acquired an Elecraft KX1 and the topic came up about pairing the KX1 with the AX1 antenna. I realized that in all of my experimenting with the AX1, I’d never paired those two. What!?!
Time to fix that!
On Thursday, September 28, 2023, I had a nice midday window to play radio. After dropping my daughters off at their classes, I stopped by the French Broad Food Co-op and grabbed a container of their chicken noodle soup from the refrigerator section.
I then made my way up the Blue Ridge Parkway (K-3378) to the Craggy Gardens Picnic Area at Bearpin Gap–one of my favorite spots on the BRP.
Despite stunning weather and the beginnings of fall foliage, the parking lot was pretty empty. After all, it was a Thursday and a good week or two before leaf-lookers descend upon western North Carolina.
I pretty much had the picnic area to myself (there was one other person there). I picked a picnic table at the top of the hill under the trees.
Mahlzeit!
When my wife and I lived and worked in Munich, the salutation I learned before any other was “Mahlzeit!” At Siemens, I remember walking through the hallways and people I’d never met before exclaimed “Mahlzeit!” as I passed by.
I quickly learned that Mahlzeit essentially meant “Lunch Time!” and I still say it today to my family when I’m about to make or grab some lunch. Funny how these things stick with you.
Now where was I–? Oh yes…
First thing I did at Craggy was set up my stove to start heating the soup. I show this in my activation video below.
If interested, here are the components of my stove kit:
Next, it dawned on me that I would need to attach the AX1 counterpoise to the KX1. I didn’t bring one of my copper clamps to attach to the outside of the AX1’s BNC connector, so I needed to find another grounding point on the KX1.
I then remembered that the KX1 has two thumb screws on the bottom of the radio. Knowing Elecraft, I assumed that these screws could be used as an attachment point for a counterpoise, but I wanted to confirm that the screw itself had a direct connection to ground.
Fortunately, I keep a small multimeter in my supplemental gear bag in my car. It’s an inexpensive Allosun Pocket Multimeter. I use it for things like this: testing.
I set the multimeter to read continuity and then placed one probe on the outside of the KX1’s female BNC and the other on one of the thumb screws. Sure enough, there was a direct connection to ground. I didn’t need to worry about the KX1 chassis paint insulating the connection to ground because the thumb screw had a direct connection. Perfect!

Lately, I’ve been kitting out another fully self-contained field radio kit that would be small enough to fit in my EDC (everyday carry) laptop bag–something super compact.
I’ve been getting some great ideas from those of you who have added your kits to the Field Radio Kit Gallery.
[By the way, if you’ve submitted your kit to the gallery and haven’t seen it yet, note that I’m posting these in the order received and there are many in the pipeline!]
I’ll likely build my EDC field kit around the Elecraft KX1 or the Mountain Topper MTR-3B, then pair it with a good wire antenna.
My EDC laptop bag: the Tom Bihn Stowaway
But this process got me thinking: if money was no object, and I wanted the most compact and versatile multi-band field kit, what radio and antenna system would I choose?
My answer? A kit built around the Elecraft KX2 and AX1 antenna.
In my experience, the KX2 AX1 combo is hard to beat. It’s compact, effective, low-profile, and you can set it up pretty much anywhere.
Let’s explore my reasoning here keeping in mind–in my world–this is a very deep rabbit hole to go down. I’ll do my best–no promises–to keep this as concise as possible:
Compact, Low-Profile, Self-Supporting, and Simple
Here are all of the components of my typical KX2 AX1 field kit:
This is all that is needed for a field activation.
And if you’re an SSB operator? You don’t really need a microphone because one is built into the KX2 (that said, I’d suggest you build a compact mic if you plan to do a lot of SSB operating).
If I wanted to make this kit even a bit more versatile? I’d add a kneeboard to the list. This gives one the ability to operate without a picnic table.
What makes this field kit so portable is that the KX2 is one of the most compact general coverage HF transceivers on the market.
It’s certainly the most compact (at time of posting) when you realize that two important components–the battery and ATU–are internal options.
The AX1 antenna is also incredibly compact–it comes apart in such a way that no one component is longer than about 6 inches. What you see in the photo above is the entire radio and antenna system.
Yes: A Compromise
Sure–and let’s get this out of the way right up-front–the AX1 is a compromised antenna, and being a massive fan of simple wire antennas myself, I know a properly deployed wire in a tree is going to provide better gain each and every time.
On Friday, September 15, 2023, my wife and I had a few hours midday to enjoy the gorgeous pre-fall weather, so we decided to go on a hike with Hazel.
My wife was the one that suggested I pick out a hike that would open the door to a short POTA activation (isn’t she the best–?).
Carl Sandburg National Historic Site (K-0804)
Earlier that week, I made a note to activate the Carl Sandburg National Historic Site in the village of Flat Rock, North Carolina. I passed this idea by my wife and she agreed that it’d make for a perfect outing.
The mission of the Carl Sandburg National Historic Site is to preserve Connemara, the home of Pulitzer Prize-winning poet and writer Carl Sandburg.
The park has a wonderful trail network and I hadn’t visited it since 2016, during the National Parks On The Air (NPOTA) ARRL event.
Technically, I could go back into my NPOTA logs and upload my Sandburg activations to the POTA site because previous activations do count, but I’m not actually motivated by my park count so much as I am just having fun working new-to-me sites under the new POTA program.
That said, my somewhat flexible, non-committal goal of having at least 100 unique parks activated for POTA before the end of 2023 was also on my mind; a small motivator to expand my POTA footprint.
Admittedly, there really aren’t many parks that are within two hours of my QTH that I haven’t already activated for POTA. The ones left, like Sandburg, are just outside the corridors I normally travel.
The Sandburg site is a beautiful one, and I think Hazel may have even remembered this spot from so many years ago. My wife and I got a kick out of how giddy she was to hit the trails, smell the smells, and meet all of the other hikers.
Hazel: “Enough talking, Dad! More hiking!”
Time to hit the trails and find an activation spot!
Knee Board Portable!
Back in 2016, I got permission from a Sandburg park ranger to place a wire in a tree in order to perform my NPOTA activation. She only asked that I perform my activation on the trail network (not at the house and goat farm).
Wow…I just checked and I had forgotten that I made a short field report of that activation over on (my other blog) the SWLing Post—check it out here. Back then, my KX2 was still very new and shiny!
Not even a scratch on the KX2 back then! Today, Hedy looks a little more field battered! 🙂
And here we are seven years later and I’m still activating the Carl Sandburg site from my lap. This time, however, I don’t have my radio on a clip board, I’m using a folding knee board:
This is my Tufteln/N0RNM folding knee board and you’ve seen me use it in numerous activation videos.
Instead of just placing my logs and radio on the knee board, like I did back in 2016, I wanted to place my entire antenna system on it, too.
You see, although I’m sure the staff at the Sandburg home wouldn’t mind me putting a wire in their trees along the hiking trail, I couldn’t find a staff member to ask, so I used this as an excuse to try something I’ve always wanted to do: mount my AX1 on the knee board as well!
Many thanks to Dale (N3HXZ) who shares the following guest post:
Portable Operation Using a Vertical Antenna Without a Counterpoise Wire!
by Dale (N3HXZ)
In a previous article that Thomas was kind enough to post, I ran experiments to determine if the counterpoise wire orientation of the Chameleon MPAS LITE antenna system in the vertical configuration in any way shaped the antenna pattern. The configuration of the antenna is shown below.
The system consists of a 17’ telescoping whip antenna, a matching transformer, a 50’ coax cable with an in-line RF choke, and a counterpoise wire (60’ long, but unwound to only 25’ for use in the vertical configuration).
Subsequent studies I performed have reinforced my earlier conclusions that the positioning of the counterpoise wire in this setup does not appreciably shape the antenna pattern. One of the comments from my post came from Stephan (HB9EA). He commented on the fact that the coax cable is indeed a counterpoise via the coax shield and that in fact my system set-up had two counterpoises.
It was Stephan’s comment which led me to contact Chameleon Antenna to discuss counterpoises with the MPAS LITE antenna in the vertical configuration. I communicated with the Director of Research and Development group at Chameleon and found out some interesting information that I wanted to pass on.
He mentioned that the system can be used with the coax cable acting as the lone counterpoise as long as the coax cable is at least 25’ long, and preferably 50’ long. The coax should be spread out and not coiled along any portion of its length. It was stated that the counterpoise wire provided with the product should be used with short-length coax cables.
With regards to a counterpoise orientation shaping the propagation direction, he stated that it is generally accepted that using only the coax as a counterpoise tends to have the antenna pattern slightly favor the direction in which the coax is laid out. Adding the counterpoise wire in a direction opposite to the coax would tend to balance out that pattern. Having the coax and counterpoise wire at some angle to each other introduces variables that make it difficult to determine the antenna pattern.
My initial study had the counterpoise wire oriented at an angle to the coax cable. I mentioned that my initial study showed that orientation of the counterpoise wire did not seem to appreciably shape the antenna pattern, and he agreed. What is unknown is the overall degree to which the coax cable shapes the antenna pattern with or without use of the counterpoise wire. This is an area I am currently investigating.
Operating the MPAS-LITE vertical configuration with only the coax cable as a counterpoise was an intriguing thought.
To test it out I teamed up with Jim (KJ3D) for a SOTA activation on W3/PT-003 (Seven Springs). We both deployed the MPAS-Lite with only the supplied 50’ coax cable attached. Coax cables were laid out in a straight line. One cable was oriented southeast, the other one oriented east. We operated on 10 Watts in CW mode. The activation successfully worked all bands from 40M to 10M. I operated an Elecraft KX2 and Jim operated a KX3. The internal tuner of both rigs easily obtained a 1:1 match across all bands.
A map of the QSO’s is shown below. Note that despite the coax cables facing to the southeast and east, we easily worked stations in the opposite directions. Hence any minor shaping of the antenna pattern by the coax orientation does not appear to impede successful communication in all directions.
In summary, the MPAS-LITE antenna system in the vertical configuration utilizing the 50’ coax cable with an in-line RF choke as the single counterpoise has been demonstrated to perform well in the field.
For portable operation where fast deployment and simplicity is paramount, using the furnished coax as a counterpoise is a quick and dirty way to get the antenna erected and on the air with reliable communication capability. Eliminating the counterpoise wire allows for quicker set-up and tear-down, and one less thing to put in the backpack!

The backstory
For those of us that work from home there are good and not-so-good things about it. One of the not-so-good things is that I’m not getting out somewhere every day like I used to, thus I embrace corporate travel as it represents a mini-escape from the day-to-day activities that would normally happen. It also gives me an opportunity to operate in the field and away from the comfort of sites nearby my home.
In late September I was in the Edmonton Alberta area for work and, as always, I brought along a set of gear to play radio. Where I’d normally drive up and park my F-350 within the boundaries of the park and operate from the cab of the truck, this time I was in a rental vehicle so I had to be well-equipped for the unknowns. I also didn’t pre-plan my stops like I normally would, I just wanted to roll up and do my best to make it work.
Not really pre-planning an activation is a stark contrast to how I normally roll as I usually pore over maps and satellite views on multiple websites to visualize where the park entrance is and where I’ll set myself and what I may encounter for surroundings when I get there. I know exactly where I’m going and just about down to the parking space. I build a set of kit up to support that/those activation/s.
With the lovely autumn weather we were experiencing in Alberta, my plan was to activate after work opportunistically around Edmonton – something I’d not yet done despite many trips to the area – and set up and operate right around 0000z. This time is after my workday, so a nice mental break from the day’s activities before kicking back for the evening. I think to my self that I’ll roll into a site nearest to where I was working arriving just before midnight UTC (1800h local) and get set up and start calling once the clock ticked over into a new day. From there I would then head to the hotel (or home) and grab a bite to eat and close my day off on a high note.
In the early fall and spring, I go over my QRP radios and give serious thought to how I’ll build compact field kits around them.
Why? I’m pretty sure it’s the pending change in weather that’s the catalyst. The temptation to get back out there and make some contacts.
Then again, any excuse: I absolutely love building field kits, and fortunately it never gets old.
The radios I’m considering at present are my MTR-3B (named Threepence) and KX1, now named Audrey. (Yep, I chose “Audrey”…thank you for all of the amazing suggestions!)
Both of these are ideal little radios for kitting out because they’re so compact and truly made to be taken to the field.
One of these two radios––and I haven’t decided which one yet––is going to live in my EDC bag.
The Tom Bihn Stowaway in black has been my EDC bag for many years. I’ll need to pay attention to the weight and bulk of this field kit, because I’ll be lugging it pretty much everywhere.
I’ve got some ideas and a couple of pouches in mind, so this will all start coming together soon.
But first…
Care to share your portable radio kit?
One of the things I enjoy doing when I’m putting together a new field kit is to check out what others have done. It’s a great way to get some fresh ideas…and besides, it’s just plain fun to compare notes.

As I often do, I hunted yet another CW POTA activator during my lunch break while working from home.
I have been learning CW for most of the year. Early on, I realized that with a bit of practice sending, and after listening to recordings of POTA activations, like those from Thomas, I could reliably send the proper exchange needed to hunt a POTA activator.
If you can give your call sign, signal report, and state abbreviation, you can make the contact. I started early on with just the basics and then added some of the common “extras” like GM for good morning, TU for Thank You and then 73. Not only is this great practice for getting on the air sending CW, it’s also very rewarding while learning CW. The exchange is short, standard, and easy to follow with a bit of practice.
CW Practice with the Morserino32 and a Cup of Coffee
Once I finished my upgrade to Extra I focused all my spare time, not much though truth be told, on practicing CW.
At some point this summer I set the goal to Activate POTA/SOTA during the W4G SOTA campout this fall. This really wasn’t an aggressive goal, one I figured was attainable but also one that I could hold myself accountable to even knowing I had a very busy summer ahead of me.
W4G SOTA Campout Summit View Yanah Mountain Bald October 2022
During one of the LICW Club classes I heard again that their goal is to get Hams on the air to make a QSO. I thought to myself, yes, that is great, and I want to do more, but I know I have made many QSOs in CW on the air, albeit very short and simple ones. So, I was curious how many.
I jumped on the POTA site and looked up my statistics. I was surprised at how may hundred I had, and yet at the same time, I was a bit disappointed. It’s not that I wanted to have made more CW contacts, it’s that I realized that they were ALL from hunting and not a single one was from calling CQ.
So, I changed my goal.
I know that Hams, especially CW operators, are a great bunch of people and they want to see new CW operators succeed, so there is lots of patience when you call CQ. So, I decided to move up my timeline. This was on a Thursday, and Saturday was a likely candidate for a POTA outing, why not–?
Saturday was my birthday, and I knew I could get away with some personal free time in the morning where I could dive in and call CQ POTA DE N5FY. The next day, Friday, I firmed it up, I would head out in the morning, bring the new to me KX2 and see what happens.
Surprisingly, I was much less nervous than I expected, I had told myself that it wouldn’t help anyways to be nervous so just do it and see what happens. I made it to my local park, to the picnic table I frequent, then setup a No Transformer 2-Wire antenna with the KX2. One press of the ATU button and I had a 1:1 match on 40m band.
Of course, I have great timing. I could not believe the stations on the air on 40m. I never did look but there must have been a contest. I moved up and down about 20kHz and there were stations everywhere! I called “QRL?” on 2 different frequencies and had a reply before I landed on open frequency where I could call CQ.
N5FY First CW Activation KX2 Setup
I had not scheduled the activation; I knew I had a bit of cell phone coverage at this park, so I set the CQ POTA message to calling while I posted a spot.
After two calls, I had my first call back. It was time!
I could have freaked out here, but I was too focused on decoding to even be nervous! Of course, I had to send a partial call and a “?” once or twice to get the full call right. Of course, I made some keying errors. But the caller had patience and worked me and we made the QSO. Now I was really excited!
I called CQ and someone sent me back dits and dahs, and I decoded what they were sending! Boy, this was fun! I continued to call CQ POTA, and tried my best to decode the replies, several pileups, and lots of “?” sent by me. But I was making contacts and having a blast!
After a couple of silent CQ calls later, I switched to 20m. And, again, started to get replies back as well as a couple small pileups. In the end, there were a couple call signs that I could not look up, l had a letter or two wrong, but with almost 20 in the log I knew I had an activation and boy was I happy!
N5FY First CW Activation QSO Map
Looking back on the activation, and after talking to another Ham, it occurred to me why I wasn’t as nervous as I thought I might be.
You see, when you are the Activator, when you call CQ, the ball is in your court, you invite people to call back and they are there for you. I almost get more nervous hunting as I don’t want to slow down an activator or run over another caller. But when you are the one calling CQ, it’s your game!
Of course there were several hiccups along the way. For one, it got HOT sitting in the sun. I ended up deploying my hiking chair on the table as a sunshade and pulled a portable fan out of the car. Even the action camera overheated while recording the activation. I couldn’t get the KXPD2 paddle to key the KX2 on 20m when I first got setup. And of course, I had lots of sending errors (although fewer than I expected to have) and sent a A LOT of “?” asking for a repeat.
That said, I am very glad to have jumped in and will continue to activate CW going forward as I continue to build my CW skills. For me, confidence in the ability to Activate on CW is great motivation for practicing, which again, is my biggest learning. If I want to be a good operator, I need to put in the effort, and going out to play radio is one extremely fun way to practice!
There’s a portable wire antenna design I’ve been wanting to put on the air for POTA and SOTA for what seems like ages: a 20 meter vertical loop.
I mentioned in a Ham Radio Workbench podcast episode a few months ago that I planned to build a field-portable delta loop antenna and that led to a mini discussion about configurations, feed points, height off the ground, etc. and how all of those factors can influence the characteristics and dynamics of the antenna.
Vertical loops are pretty fascinating and incredibly effective.
Delta loops are super easy to build (no more difficult than an EFHW) but this summer has been insanely busy for me and I simply hadn’t gotten around to it yet.
Then my good friend Joshua (N5FY) who runs tufteln.com sent me a prototype 20M delta loop in the mail. We’d been talking delta loops and he couldn’t help but build one. He asked that I take it to the field and put it on the air, then give him any feedback and notes I might have.
Joshua’s design incorporates a 4:1 transformer and was cut to be resonant on 20 meters. I’d actually planned to build one identical to this because the type of loops I’ve deployed at home have been fed with ladder/window line which isn’t as portable as something I could feed with RG-316.
Holmes Educational State Forest (K-4856)
On Friday, September 1, 2023, I grabbed the delta loop antenna and the KX2, then made my way to Holmes Educational State Forest.
I knew that Holmes wouldn’t be busy and that there were a number of options for spots to set up.
After a little scouting, I found a great site to set up the antenna.
I planned to set up this antenna as close as I could to an equilateral triangle with the apex up about 30 feet and the feedpoint in the middle of the base of the delta.
Deploying the antenna in this configuration meant that I only needed one line in a tree to hoist the apex of the delta and two lines to pull out the corners of the base.
I brought along some paracord with tent stakes to secure the base corners of the loop. In the end, though, I simply attached the paracord to trees instead of using the stakes.
I (somewhat reluctantly) made a video of the entire activation including the antenna deployment. I wanted to take my time deploying this antenna for the first time, so the antenna deployment section of the video is much longer than usual.
You absolutely cannot see the loop in this photo, but it’s there…I promise!
In the end though? It wasn’t as difficult as I thought it would be. The last vertical delta loop I deployed was a 40 meter loop which is roughly double the size–in my head I was expecting the aperture to be larger than it was.
My arborist line and 12 oz weight hanging to provide a gentle tension to hold the apex of the loop up.
The 20 meter loop is actually pretty compact and almost as easy as setting up as an inverted vee.
On Sunday, August 20, 2023, en route to check in with my parents, I popped by Lake James State Park for a little early evening POTA fun.
In the car, I’d pack the Elecraft KX2 kit and I still had the REZ Ranger 80 vertical antenna system on loan from REZ Antennas (it’s since been returned to them).
The last time I deployed the REZ was on Mount Mitchell in some pretty sketchy weather. While I recorded a couple of short videos, I didn’t record a full activation video since we were having a family picnic that day.
Before sending the Ranger 80 back, I wanted to fit in a proper activation showing how I deploy the antenna, how I tuned it for the first time, and how it might perform on the 40 meter band.
Lake James State Park (K-2739)
It was golden hour at Lake James and the park was bustling with activity. There were kids running around, parents chasing them, and several families cooking out at the numerous picnic sites.
I sought out a location that was private and quiet mainly because the Ranger 80 antenna has four 31 foot radials, thus a large footprint; I didn’t want children, pets, or anyone tripping on the ground radials.
Fortunately, one of my favorite spots overlooking the lake was free, so I could simply set the Ranger 80 up in the woods where folks weren’t walking.
The Ranger 80 is super easy to deploy: simply extend the vertical, attach it to the top of the base, then attach the stainless spike to the base and plunge the entire thing into the ground. Next, you deploy the four radials and connect it to the base of the antenna.
It only takes a couple of minutes especially since the counterpoises are wound using the over-under method. I simply tossed each line into the woods and didn’t worry if they were all lying perfectly on the ground.
Note to REZ: Consider offering optional high-visibility counterpoise wires–for those of us setting up in busy parks, it would make the ground radials more conspicuous to passersby.
Next, I needed to tune the Ranger 80 for the forty meter band.
Typically, when I use a sliding-tap tuning coil style antenna like this one, I turn on the radio and move the coil until I hear an audio peak, then I fine tune it by sending a “dit” on the radio, checking the SWR, and adjusting the coil slider.
That evening, though, I had my RigExpert AA-35 Zoom antenna analyzer so I set it to continuous SWR monitoring and adjusted the coil until I achieved a good match. Easy.
I should add here that when you use an antenna like this frequently, you learn where the best tap points are on the coil thus tuning becomes easier. My friend Alan (W2AEW) actually made a PVC rig for his coil antenna (click here to check it out).
With the antenna all set up and ready to rock-and-roll, I simply hooked up the Elecraft KX2, my VK3IL pressure paddles, and prepared the logs.

The L-match is placed on the ground and connected to the HS1B or KVE60C antenna analyzer using a one meter long 50-3 coaxial cable. (This reduces the length and weight of the coaxial cable.)
