On Friday, September 10, 2021, I made a detour to the Table Rock Fish Hatchery (K-8012) on my way back to the QTH.
I love this site: it’s fairly remote, has tall trees, loads of space to set up antennas, convenient picnic tables, incredibly friendly park rangers and, most importantly, a welcoming party.
Welcoming party
These two greet me each time I’m at Table Rock. They’re incredibly friendly and now that they know I’m a complete and total sucker for dogs, they hang around and get attention for quite a while.
Many thanks to Pete (WB9FLW) who shares the following information about the new QDX transceiver from QRP Labs:
The “QDX” (QRP Labs Digital Xcvr): a feature-packed, high performance, four-band (80, 40, 30, 20m) 5W Digi-modes transceiver kit, including embedded SDR receiver, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference. QDX transmits a SINGLE SIGNAL, it is not an SSB modulator with associated unwanted sideband and residual carrier, or intermodulation due to amplifier non-linearity. QDX outputs a pure single signal.
The Optional enclosure is black anodized extruded aluminium, very sturdy and elegant. The enclosure size is 89 x 63 x 25mm without protrusions. The front and rear panels are drilled and cut to match the QDX PCB with laser-etched lettering. The enclosure includes four self-adhesive feet.
List of features:
Four bands 80, 40, 30 and 20m
5W output at 9V supply (can be built for 4-5W at 12-13V supply)
Single signal transmission (zero unwanted sideband, zero residual carrier, zero intermodulation distortion)
Solid-state band switching and transmit/receive switching under CAT control
High performance embedded SDR SSB receiver with 60-70dB of unwanted sideband cancellation
Built-in 24-bit 48ksps USB sound card
Built-in USB Virtual COM Serial port for CAT control
Si5351A Synthesized VFO with 25MHz TCXO as standard
Easy to build single-board design, Professional quality double-sided, through-hole plated, silk-screen printed PCBs
All SMD components factory assembled
Connectors: 2.1mm power barrel connector, USB B (for audio and CAT control), BNC RF input/output
Built-in test signal generator and testing tools
Receive current 100mA, Transmit current 1.0-1.1A for 5W output with 9V supply (around 0.7A for 5W with 13V supply).
Optional aluminium extruded cut/drilled/laser-etched black anodized enclosure
Absolutely amazing! I’m not sure how Hans is able to innovate at the pace he does, but I think we’re all better for it. This will be a big seller for those who’ve been looking for a high performance QRP digital mode transceiver.
On September 20, 2021, I had a full day planned in town. It was one of those days where my few errands and appointments were spread out across the day in such a way that driving back home between appointments made no sense. I knew I might have a bit of time to kill.
The big appointment holding me in town was recall service work on my Subaru that would take most of the day. The dealership reserved a loaner car for me.
That morning, I cleaned out my car (removing a couple of radios and antennas) and I packed a backpack with the supplies I’d need for the day; water, sandwich, laptop, and (fortunately) my Elecraft KX2 and AX1 antenna.
I would take this pack with me in the loaner car as I ran my other errands. I remember thinking that there was likely no possibility of doing an activation–it was rainy and I knew even getting set up at the service center might take an hour. I packed the Elecraft gear nonetheless. (Never leave home without a radio, I say!)
That morning, I drove to the Subaru dealership and–long story short–the service work had to be cancelled. While I wasn’t happy that I’d made the early morning trip to the dealership for nothing, this did essentially free up a good portion of my morning to play radio. Even though I had my own car for the day, I had completely emptied it of radio gear, so the KX2 and AX1 were truly all I had. Continue reading Elecraft KX2 and AX1: Seriously…how effectively can such a compact field kit work?→
Shortly after acquiring a lab599 Discovery TX-500 earlier this year, I did what I always do: invest an insane amount of time in researching and configuring a dedicated field radio kit.
As I’ve mentioned numerous times, I’m a serious pack geek, so this is incredibly fun for me even though the choice is often difficult.
I like to buy packs and cases from manufacturers in the US and Canada when possible, so started searching through all of the options.
Requirements
I wanted a pack that was compact, versatile, and offered proper padding (even knowing the TX-500 is a rugged little transceiver). I don’t handle my packs with kid gloves, so I expect them to cope with sometimes rough field conditions and still protect the gear inside. I also like a certain level of organization inside the pack.
I wanted the kit to be relatively compact, but large enough to hold the transceiver, all accessories and connections, logging pad and pencil, paddles, a proper arborist throw line, portable ATU, and a 3Ah LiFePo4 battery. A the end of the day, I wanted this TX-500 field kit to be fully self-contained.
In the end, I adopted a pack with which I’m already very familiar…
The Red Oxx Micro Manager
Red Oxx is my favorite pack company and if you’ve been a reader for any length of time, you’ve obviously seen a number of their bags and packs in my field reports.
Back in 2016, when they introduced the first iteration of the Micro Manager EDC bag, they actually reached out to me–as an existing customer–knowing that I had been looking for a good radio pack with proper padding (many packs don’t require side padding and internal padding). They sent me a prototype of the Micro Manager for my feedback and then incorporated some of my suggestions.
I also purchased a Micro Manager for my wife who quickly turned hers into a mobile art studio!
Much like my buddy Steve (AC5F)–whose XYL creates some amazing water color art in the field–my wife (K4MOI) is also an artist and loves to paint/draw during park and summit activations. Her art kit is always at the ready and she’s traveled with it extensively over the past five years.
The Micro Manager is a pack carried over the shoulder, much like a messenger or laptop bag. Those times when my field activations require a lengthy hike, I’ve simply pulled all of the items out of the Micro Manager (since I do modular packing, this is super easy), else I’ve even been known to stick the entire Micro Manager pack into a backpack!
Over the years, Red Oxx has made iterative upgrades to the Micro Manager including a pleated front pocket, slip-in external pocket, and they started lining the internal pocket with a more flexible and thinner dense foam padding. The new padding not only fits the TX-500 better than the first Micro Manager version did, but I believe it will have enough dimension to accommodate the TX-500 battery pack when that’s available next year.
Inside the Micro Manager I also use a Tom Bihn Large Travel Tray to hold all of the TX-500 accessories: key, microphone, ATU, battery, and cables.
I own a number of these large travel trays and highly recommend them. I especially like the ballistic nylon versions for radio kits as they open and close so smoothly.
Video tour
I made a short video tour of the TX-500 Micro Manager kit before a recent activation at Table Rock:
I’ve used this pack for a number of field activations and couldn’t be more pleased. Looking back at the contents, it’s funny: the pack and almost every single item inside (save the notepad and pencil) are made in the USA while the radio is made in Russia! A bit of international harmony going on here!
If you have a field pack for the TX-500 (or any radio), I’d love to know more about it. Please consider commenting with details or even submitting a guest post with photos!
One of the closest parks to my parents’ home in Hickory, North Carolina (where I travel most weeks) is South Mountains State Park.
Despite its convenient location, I haven’t activated South Mountains many times and, in fact, the times I have activated it, I’ve always found it a struggle to log the ten contacts needed for a valid park activation. I suspect it’s had less to do with the physical location of my operating spot (which has admittedly been in a bit of a “bowl” surrounded by hills) and much more to do with the fact that propagation has been crappy on the days I tried to activate.
Ironically, I’ve activated the adjoining South Mountains Game Land numerous times with wonderful success. It’s funny how that works.
South Mountains State Park (K-2753)
I had a good reason to hit South Mountains on September 9, 2021. My buddy Max (WG4Z) had just purchased an Elecraft KX3 at the Shelby Hamfest (at an incredible deal, I might add). He plans to pair it with a Chameleon CHA TDL (Tactical Delta Loop) he has on order.
Sometimes we do things that take us outside of our comfort zone.
That’s exactly what I did on September 8, 2021 at Tuttle Educational State Forest (K-4861).
My friend, Jérôme, asked I would consider doing a POTA activation video in French!
Jérôme lives in France and wants to do a POTA activation there eventually, but had a number of questions about what to do in the field (spotting, logging, etc.). He’s been watching my videos for a while but admits that while he can understand written English (with the aid of Google Translate), he doesn’t understand spoken English.
Although I regularly listen to news and YouTube videos in French, it’s been ages since I’ve spoken French for any extended period of time.
Jérôme has been bugging me about the French video for some time, actually, but I’d put it off because there were a number of radio terms I simply never learned when I lived in France (well before I was a ham radio operator).
When he very diplomatically asked me again via email on the morning of September 8, I thought, “Why keep waiting? Just do it!”
After completing a successful activation at Fort Dobbs State Historic Site on Wednesday, August 25, 2021, I decided to fit in one more activation that day. I thought about heading out to one of the game lands I hadn’t hit in a while, but frankly, I needed a park a little closer to home due to my time constraints that day, so Lake Norman State Park it was!
Lake Norman State Park (K-2740)
Lake Norman is such an effortless park to activate. Their main picnic area has numerous tables (including two large covered areas), and tall trees providing support for antennas and much needed shade from the NC summer sun!
One thing I had not decided upon was what antenna I’d use at Lake Norman. Earlier, I used my trusty speaker wire antenna at Fort Dobbs, but I like to shake things up. I checked the trunk of my car and found the Chameleon MPAS Lite. Seeing how propagation plummeted after my previous activation, I decided that I wanted a large wire antenna deployed rather than a vertical.
The MPAS Lite can be configured as a wire antenna, of course: instead of attaching the 17′ whip to the “Hybrid Micro” transformer, you attach the 60′ wire that might normally be used as a counterpoise.
Setting it up was quite easy, in fact. I used my arborist throw line to snag a tree branch about 45′ high, then attached the throw line to the floating dielectric ring on the Chameleon wire spool. I stretched the entire length of wire out, attached the end to a tree, then hoisted up the center, forming an inverted vee shape.
Even thought the 50′ coax shield would act as a counterpoise, I really wanted another ground wire attached, so I pulled one of the wires off of my speaker wire antenna and attached it to the grounding post of the MPAS Lite’s stainless spike. I figured a little extra counterpoise wouldn’t hurt.
Although I’d never used the CHA MPAS Lite quite like this, I was pretty confident my Elecraft T1 would find a match. The Chameleon transformer (the Hybrid Micro) brings most any (but not all) lengths of wire within reasonable matching range of an ATU.
I started on 40 meters and found that, without employing the ATU, I had a match that was slightly below 2:1. Not terribly surprising since I had a good 60′ of wire in the tree. Still, I hit the tune button on the T1 and easily achieved a 1:1 match.
I will add here, though, that perfect 1:1 matches are not that important–especially at QRP levels. I’m certain the TX-500 would plug along with a match of 2.5:1 or higher and still radiate perfectly fine. I’ve known hams that truly equate that 1:1 match with an antenna that’s performing efficiently, but that’s not always the case. Keep in mind a dummy load will give you a 1:1 match but is hardly efficient. The ATU’s job isn’t to make the antenna radiate better–it’s to match impedance.
The CHA MPAS Lite will get you within matching range across the HF bands and, many times, it’s close enough that an ATU isn’t really needed.
I started calling CQ POTA on 40 meters and within 28 minutes had logged the ten contacts needed for a valid park activation–all with 5 watts, of course. I was very pleased with these results because, as I had suspected, the bands were still pretty darn rough.
I then moved up to the 30 meter band where I worked a couple of stations and then, for fun, found a match on 80 meters and worked one NC station (possibly on ground wave!).
Here’s a screenshot of my logs from the POTA website:
I must say that I do love using the Discovery TX-500. It’s such a brilliant little field radio. I’m just itching to take it on another SOTA activation soon!
I’m also loving the TX-500 field kit that I built around a Red Oxx Micro Manager pack.
I used the same bag (different color) for my KX2 NPOTA field kit in 2016. It’s such a great size and can even easily hold my arborist throw line along with all of the station accessories and rig, of course. I’ve made a short video showing how I pack it and will upload that video when I have a little bandwidth!

I did make a real-time, no-edit video of my entire Lake Norman activation. Feel free to check it out below or via this YouTube link. No need to worry about ads popping up–my videos have no YouTube ads!
A Brief Public Service Announcement…
If I have a little advice for you this week, it’s this: don’t wait to play radio because someone says you don’t have the right gear for the job.
I received an email this morning from a ham that’s new to field operation and just received an antenna he had ordered. He was upset because a YouTuber claimed his antenna was basically a dummy load. To add insult to injury, he also found a blogger or YouTuber was also highly critical of his recently-acquired Yaesu FT-818. [Note that the FT-817ND–the 818’s predecessor–is one of my favorite field rigs.]
Keep in mind that many of these YouTubers are trying to produce “click bait” videos that will stir up a reaction and, thus, increase their readership numbers which will have a direct and positive impact on their ad revenue. It’s a red flag when someone doesn’t have real-world examples and comparisons proving their points and typically a sign that they’ve never even used the products in question.
I’ve been told antennas I use don’t work, yet I’ve snagged some incredible QRP DX with them. I’ve been told that some radios I use are junk, yet I’ve hundreds of successful field activations with them. And funniest of all are those who tell me that QRP is ineffective and–quoting from an actual message recently–“a complete waste of time.”
My advice is to simply ignore these folks. The proof is in the pudding! Get out there and play radio! In the words of Admiral Farragut, “Damn the torpedoes. Full speed ahead!” 🙂
Thank you!
As always, thank you for reading this field report and a special thanks to those of you who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement–my content is always free–I really appreciate the support.
This month, we’ll take a deeper dive into the types of radio kit you might choose to assemble based upon your activity goals. And finally, we’ll look at my “golden rules” of field kits, which I hope you’ll find useful.
Types of field radio kits
I configure and outfit my radio kits based on the environment in which I plan to deploy and operate, and which determines in no small way just what I need to pack besides the basics.
I roughly divide my field kit types as follows…
The Field Day or “Picnic Table” Kit
This is probably the most popular type of field kit in the world of amateur radio. Picnic table kits are designed with portability in mind, but not designed with distance hiking in mind. This is a very popular type of kit for Field Day or park activations through POTA or WWFF.
These kits are typically packed in a backpack, a Pelican-type utility case, or a self-contained and field-ready box.
My picnic table kit is packed in a large Red Oxx C-Ruck rucksack. If I haven’t already made it clear, I’m a self-professed pack geek and I love this Red Oxx Pack because it has large zippered pockets on the outside, a rain flap with storage on top, and one large compartment on the inside.
Many thanks to Carolanne (N0RNM) who shares the following guest post:
A Booty Boss Micro Radio Kit
by Carolanne Fisher N0RNM
I am a bit of a tinkerer and an aspiring POTA activator, so when I received my Elecraft KX2 a couple of weeks ago with its way-too-big carry bag, I immediately started to think about ways I could keep the KX2 protected on the trail in a much lower-profile, light-weight, and easy-to-carry kit that would always be ready to go. The trick was to find a case of just the right size, with plenty of built-in organization and flexibility to build the kit around. I found what I hoped would be exactly what I was looking for from the excellent Red Oxx Manufacturing company (redoxx.com) — a soft-sided compact bag they call the Booty Boss Waist Pack. At least the specs looked good…
I am certain that whoever designed this bag did it specifically with the KX2 in mind. It is small enough to take anywhere, yet it fits my entire setup, including the radio, an extra battery pack, an AX1 antenna, complete with its 40 meter extension coil, 2 counterpoises, along with other necessities perfectly. I printed and spiral-bound a small note pad, shoved in a few accessories, and I was ready to rock and roll. The bag is even lightly padded for a bit of peace of mind. I am a CW-only kind of op so a mic is not a concern, especially since if I absolutely needed to use phone, the KX2’s built in mic would serve perfectly fine.
I tested the bag during several “back-porch activations” and everything seemed to work great. That is until I tried to use it under more realistic conditions — without the shaded picnic table to deploy on and the comfortable chair to sit on. Sitting on a rock while balancing the radio on my knee with its floppy AX1 antenna, and note pad while actually tying to send code proved to be a bit more than I could handle. It was clear that something like a clipboard was necessary to complete the micro radio kit, but a normal-sized clipboard would completely break the one-tiny-bag ethos.
A couple of years ago I designed and 3D printed a portable folding easel to support my sketchbook, watercolors, water etc. when out and about nature journaling or urban sketching. It worked great for that so I made a smaller version, added a recess for the radio and made sure it had room for the notepad. In order to fit in the bag, the size, even when opened to its full 8” x 9.5” size is a bit cramped, but with the addition of a leg strap, like a pilot’s lap desk, it it does the trick.
Here is everything currently in the bag and how it all gets stowed:
Front zip pocket
13’ and 33’ counterpoises for use with the AX1
An extra 28.5’ random wire antenna with 50’ of mini throw line attached (fly fishing backer line with two 1 oz. fishing weights) along with a 17’ counterpoise
Front main compartment
Folded radio desk
Note pad
Pencil
Two small interior pockets
Binder post
Spare KX2 Battery
Interior zip pocket
Spare set of paddles w/ KX2 attachment and cord (by Peter GM0EUL)
Spare pencil
Copy of my radio license
Rear main compartment
Ax1 antenna (whip, 20 and 40 meter coils) lying the bottom
KX2 (fits in the bag with the KXPD2 paddle attached)
Large slip pocket
Ear phones
The KX2 fits flat on its back or up on its kick stand in its custom sized recess. A sticky gel pad (from Amazon) placed in the recess pretty much “glues” the rig to the desk until you want to remove it.
Although I don’t use it all that often, the AX1 is my all-purpose, quick-to-set-up and a snap-to-put-away antenna. I mount the bipod inboard to the radio (over the BNC connection) so it fits on the desk to provide support. I wedge the bipod out from the rig with a spare pencil or a stick from the trail placed between the rig and the front leg to take some of the twist pressure off the BNC connector.
Although the micro radio kit holds everything I need to make contacts, there are plenty of times that I like to have a more luxurious set up — a folding chair and table, my Alex Loop antenna, tripod, lunch, iPad, etc. Or perhaps I’m off for a multi-day and need an external battery, a solar charging system, food, shelter, etc. This scenario is precisely where the micro radio kit really comes into its own. It is tiny enough to slip into just about any bigger bag or placed on the waist belt of a backpack. No more wondering if you remembered this or that bit of radio kit or loosing track of things you borrowed from another kit. If you actually did forget something extra you thought you packed, not to worry, the micro radio kit has everything you need right inside to make contacts.
As a tiny everything necessary, nothing extra radio bag, the Booty Boss micro radio kit is, well, the BOSS!

Thank you so much for sharing this, Carolanne! As you know, I’m a massive fan of Red Oxx gear and also own the Booty Boss. It’s simply brilliant that you can even pack a folding radio desk inside! Thank you so much for sharing your field radio kit with us.
As I’ve mentioned a number of times on QRPer and on the SWLing Post, I’m a pack geek. I enjoy organizing and packing my gear for field radio activities and travel.
Last week, I made a very quick overnight trip to visit my parents. My time during this trip was very limited and I did not plan to fit in an activation, but Monday morning, I was able to knock out an errand very early and that freed up a couple of hours in the early afternoon. Fortunately, prior to leaving my QTH, I decided to pack a few travel items in my GoRuck GR1 pack along with a field radio kit built around my Elecraft KX2.
I never leave home without a field radio kit because I never know when an opportunity to play radio might happen.
On the way home Tuesday, I popped Lake Jame State Park and fit in a quick, last minute activation. Moments before arriving at the lake, I received a request from one of my YouTube subscribers asking if I would make the occasional video showing what’s in my radio packs and field kits.
I’ve been meaning to make these videos but, frankly, often forget when I arrive at a park or summit because I’m just a little too focused on starting my activation.
Since I had some overnight items in my pack, it wasn’t a typical SOTA or POTA field kit, but I decided to make the video anyway. After all, I love watching videos about how others pack and organize their radio and travel kits. But then again, I’m a pack geek. I did mention this right–?
Although I’m not always the neatest person (my wife is probably chuckling at this gross understatement), I’m a meticulous and very organized pack geek. What you see in the video is exactly how I pack when no one is looking. 🙂
I’ll add here that if you’re interested in field radio kits and packs, I’d encourage you to check out my Anatomy of a Field Radio Kit series; Part 1 has already been published and Part 2 will be posted later this week. In Part 2, I take a much deeper dive into safety gear I take on SOTA activations.
Gear
In the video, I mention that I would attempt to link to all of the items in my pack. I spent time sorting out links this morning; many links go straight to the pack manufacturer because the packs I use typically have no distributors other than the manufacturer, I have also purchased a lot of the smaller items on Amazon, but many can be found in big box stores like Walmart, Target, Canadian Tire, etc.
If I missed something, let me know in the comments.
Video
Like all my videos, this one us unscripted, made in one take (unedited), and also has no ads:
Out of order…
So this video was made prior to an activation at Lake James last week. I’ve mentioned before that my Internet speeds at the QTH are worse than dismal, but since this pack video was relatively short, I was able to upload it ahead of the activation video (it took 1.5 days to upload this 2GB file).
The activation video will be published in another week or so depending on my access to some proper broadband service.
Any other pack geeks out there?
I would love to share photos, descriptions, and/or a video of how and what you pack for field activations. If you’re interested in submitting a guest post, please do so!
Also, I’d love to hear about your favorite packs and how well they’ve held up with time.
