(tr)USDx Ultralight Portable Kit

by Jim (KI7URL)

I like to take amateur radio with me wherever I go. In my backpack, I keep a Yaesu FT-60 (powered by 18650 batteries, but that is a different discussion). But I do not like to limit myself to VHF/UHF.

My wife, on the other hand, does not think my “go bag” should take up a significant portion of our suitcase when we travel. I did build a slimmed-down go kit with my Yaesu 891, but that was still north of 12 pounds (vetoed by Wife). Then, I made a go kit with my Yaesu 818, but that was still near the 10-pound zone (again, vetoed). I needed a slimmer package.

I turned to the likes of the QCX mini or other CW-only radios. The problem is that I still am far from proficient with my code, so relying only on CW was a bit more frustrating than I wanted it to be. The (tr)USDx, an open-source radio about the size of two stacked decks of cards, interested me in both price point and functionality. It has SSB, CW, and digital capabilities….on five different bands! Once it was in my hands, I had to build a kit around this new radio!

I want to keep my radio protected, so I started with a small dry box. On the inside, I printed a ‘redneck laminated’ (see also: packing taped) a quick setup guide for using the radio on digital modes if I ever have an in-field case of “the dumb.”

The radio is powered by a small RC battery. I chose this for size, weight, and availability (had it lying around from another project). When fully charged, it reads 12.6 volts. I added powerpole connectors to it because who does love powerpoles (be careful not to short the battery when adding power poles)? I have a small power adapter that goes from powerpoles to the 1.3mm connector so I can use my bench supply or other power sources without making another cable.

I have two antennas that I use (a K6ARK end fed and a QRP Guys No-Tune end fed with 26 gauge wire for 20m). But I like the QRP Guys one because I mostly do 20m and I think it was slightly lighter than the K6ARK antenna (don’t quote me on that though, I loaned the K6ARK one out and have not gotten it back). Plus, not having a tuner lightens my load as well!

Deployed for digital modes.

I have a retired smartphone in my kit that I use for some logging and some other ham-related apps, but mostly for FT8 using the FT8CN app. I also have WoAD on there and soon I hope I can get WinLink functionality with a small TNC as per this video by OH8STN. HF WinLink would be a good benefit with a lighter load than packing in a laptop or Raspberry Pi.

The kit weighs in at 2 pounds 6 ounces (just over a kilogram). This could be stripped down if I only did an SSB, Digital, or, gasp, a CW activation. But as it stands, the small form factor and low weight make the wife happy!

Amazing POTA Fun: Pairing the Elecraft KX1 and AX1…but first, a little lunch!

8 Comments

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:

Quick continuity check!

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!

Coffee, QRP, & Question: Is any field kit more portable and versatile that Elecraft’s KX2/AX1 combo?

35 Comments


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.

I recently published a video showing how the KX1 and AX1 can fit on a kneeboard.

Portable and Versatile

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.

Also, people who live in more remote parts of the world–say, Hawaii, the Yukon, or Perth, Australia–where the amateur radio density is sparse within their propagation footprint, the AX1 will not be as productive as it is for me here in the eastern half of North America.

If you’re not familiar, SOTAmat is an incredibly valuable app and tool for spotting yourself on the SOTA or POTA networks when you’re truly off-grid and outside the range of mobile phone service.

Check out this two minute intro to SOTAmat:

Setting up SOTAmat for the first time can be a bit confusing, but it’s not difficult. It is important, however, that everything is set up in advance of your SOTA or POTA adventures.

Our friend Vince (VE6LK) has just published a “Quick Start” guide to SOTAmat. It’s concise, and covers everything you’ll need to get set up and running with SOTAmat!

Click here to watch on YouTube.

Thanks for putting this tutorial together, Vince!

SOTAmat is an incredibly powerful resource for those of us who activate parks and summits in remote locations. I highly recommend downloading the app and making it a part of your SOTA/POTA tool kit!

The prettiest activation ever – Spray Valley Provincial Park

4 Comments

As always there are lots of links within the article. Click one! Click them all! Learn all the things! ?

Ahhh .. few things in life compare to the view one sees while lakeside in the mountains. The flat water is a stark contrast to the towering mountains nearby. There is at least a 4000′ difference in height between the two at my destination in this story. For me, nothing so succinctly tells me where I fit in the world as when I stand among these giants.

So It was with that big goal in mind that a drive through the mountains of Alberta’s Kananaskis Country region was called for. The drive would take me through sweeping vistas, over high mountain road passes, along nearly 100km of gravel roads in no-cell-service backcountry while racking up nearly 400km of travel in one day.

Along the way I activated two never-before done parks in the POTA system and scouted out one more to be done at a future date. This is the story of the lakeside activation… but first, watch the short video to understand why I’m gushing on the beauty of this particular spot and written this atypical (for me) article about the activation itself.

The Drive to the activation

Overview of the trip. Darker lines indicate gravel roads. First activation is along the westernmost gravel road along the lakeshore.

For those of you that want to replicate this trip, here’s the route I took shown on the map above.

From just before when I turned north off Highway 541 to Highway 40, and until I reached Canmore, there is zero cell service. Same again turning onto Highway 68 from 40 until Bragg Creek.

Alberta has much backcountry that is well beyond cellular range. Working at The Candy Store(tm) as I do, I have access to items like the Zoleo Satellite Communicator to give me text messaging and SOS capabilities should I need them. Before I discovered SOTAmat, I used the Zoleo for all of my spotting in backcountry.

Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!?

6 Comments

Sometimes, I like the odd “exercise in futility.”

I enjoy shaking up routine and since POTA and SOTA activations are my routine, they end up being the shakers.

On Monday, September 18, 2023, I found out that our planet was rotating into a large CME (Coronal Mass Ejection). This CME made all of the space weather news and we planned for either some potential radio blackouts or at least very unstable conditions.

As I’ve said many times before, I never let the potential for poor propagation stop me from hitting the field. Don’t let it stop you either.

Lake Norman State Park (K-2740)

I had a full afternoon to play radio, so I made my way to Lake Norman State Park.

En route, I tried to think of a way to shake up the activation a bit. I planned to activate at the same spot I had during my last visit because I knew the park’s main trail system was still closed and, frankly, I wanted to take advantage of the EV charger at the visitor’s center again!

I’d packed MW0SAW’s End-Fed Half-Wave (the gift that keeps on giving, Steve) and I did have one new radio toy (more on that later).

I also had a lot of time–at least, more than I normally do during a POTA activation–so I thought it might be fun taking my KX2 down to the lowest power setting it has: 100 milliwatts.

I’ve activated parks with 100mw before, but never intentionally on a day when I knew propagation would be poor.

I figured with enough time, maybe I would get the ten contacts needed for a valid POTA activation.

If not, it would be fun trying!

Why Milliwatting?

At the end of the day, I think taking our radios and antennas to their low-power extremes gives us a taste of what we can actually do with so little signal.

I remember shortly after I bought my first Elecraft KX1 in 2008, I was speaking with a local ham and he told me that a maximum output of three watts was pretty useless and that I really needed a minimum of five watts if I expected to make any contacts.

Part of me did feel like perhaps I’d bought something more akin to a toy–fun to look at and hold, but not terribly practical.

Then I started using that KX1 to make contacts and even carry on extended rag chews. Turns out, three watts gets a lot done!

Today, I’ll often run my MTR-3B with three watts or even less when activating a summit and the results are simply outstanding–fabulous DX and contacts galore.

I know 100mw is a proper compromise, but I like knowing what I can achieve with so little. Tinkering with it in the field and listening to signal reports (also reading RBN stats) gives me a good idea.

In an emergency situation? If I could only push 100mw into a decent antenna, I know it wouldn’t be ideal, but I know it wouldn’t be futile either.

Begali Adventure Dual

Another activation motivation was the opportunity to test my new-to-me Begali Adventure Dual paddles. Continue reading Testing the Ionosphere: A 100 milliwatt to 1 watt POTA Activation During a CME? Why not!? →

A Recap of the 2023 W4 SOTA Fall Campout

13 Comments

Another W4 SOTA Fall Campout is in the books! What amazing fun.

This year, the campout was held at Lake Rabun Beach Recreation Area in north Georgia.

Once again, Joshua (N5FY), and I shared a campsite. He arrived Wednesday afternoon and I showed up Thursday afternoon around 2:30 PM.

There was quite a lot of wet weather in the forecast, so I opted to bring my large 6 person tent (the orange one above) instead of my two person ultralight tent. My thinking was that, if need be, we could us the large vestibule on this tent as shelter while eating and cooking.

Joshua was way ahead of me, though, and brought a canopy for the picnic table.

After pitching my tent and setting up, Joshua and I discussed how we should spend the rest of the afternoon. One thought was to try to squeeze in a SOTA activation, but we would have been fighting sunset at the end of it.

Instead, Joshua suggested that we build some antennas.

It was then I noticed that Joshua’s picnic table canopy had a built-in spool of 26 gauge wire!

I shouldn’t have been surprised. Joshua is the fellow behind the Tufteln brand of antennas. Turns out, he brought along a full antenna-building station.

I built a long random wire antenna and started a 30M EFHW.

That evening, we had friends pop by the campsite, ate dinner and fit in a quick POTA activation.

We didn’t have to drive to the activation site because our campground was in the Chattahoochee-Oconee National Forest (K-4473). Continue reading A Recap of the 2023 W4 SOTA Fall Campout →

Field Radio Kit Gallery: VA7EKA’s Yaesu FT-857D Field Kit

12 Comments

Many thanks to Andrew (VA7EKA) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page.

You may note that this isn’t a QRP radio, but the FT-857D will run QRP power! If you would like to share your field kit with the QRPer community, read this post. Check out Andrew’s field kit below:

Yaesu FT-857D off-grid portable kit

Andrew (VA7EKA)

As part of my amateur radio operations, I’ve quickly seen the advantage of having a small, portable radio I can operate anywhere and deploy quickly. Especially as I don’t have a permanent HF antenna installation at home, being able to set up in the yard (or even indoors) in a pinch is pretty high on the list of requirements for me.

I started reading online and watching videos about this topic, and found an excellent video from KT7RUN “The Tech Prepper” (and an earlier one) which showed a super-slick portable radio setup featuring the Yaesu FT-857D. Prior to finding those videos, I had already acquired an FT-857D due to its all-band, all-mode operation and compact size, and Gaston KT7RUN’s kit seemed like a very compelling setup for this radio.

Here’s what I’ve ended up with for my off-grid-capable “grab’n’go” radio station:

Inventory

Currently this is the inventory for this kit:

Antenna options:

and for charging this station in the field…

Details

Of course, the core of this kit is the radio. It’s popular for a reason. All-band, all-mode “shack in a box” in a truly portable form factor. Capable of 100w operation, it’s more than enough to make whatever contacts you need. In my case, because the battery has a max 20A continuous-discharge specification, I wouldn’t actually transmit at a full 100w with this exact configuration. Not a problem – I’m not expecting to transmit at those levels with a pack of this size.

The pack frame is truly solid, though it adds a good amount of weight (1.364lbs with all options). It’s absolutely worth it though. Not only does it provide rigidity and protection, it also provides convenient mount points for attachments, like the relocated antenna connections and Digirig holster. I could securely attach additional items if needed.

The battery just fits into the MOLLE pouch which is pretty lucky. I got a small PowerPole distribution block so I can not only connect the radio to the battery, but also the Genasun solar charge controller and whatever other power-related accessories I might use (e.g. Dakota Lithium’s 5v USB charger which I’ve adapted to PowerPole). Solar-wise, the charge controller I went with has a little more capacity than what I’m using currently with the 75w panel. I figured I should bump up to the 10amp charge controller to allow for a larger solar panel later on.

For CW operation I’ve relocated the jack with a basic 3.5mm audio extension cable going up through the bag and looped through the PALS webbing on the High Ground Gear PRC-117G bag. For a key I’m usually packing a basic 3d-printed iambic paddle I got at a swap meet for $20. I’d love a N0SA SP4 paddle but… $$$ :‘D

In the following photos you can see how I’ve laid out the relocation cables. I specifically took photos of these to show people who want to re-create this kit, because it was pretty tedious to get it all in there. Hopefully these will save someone a bit of time. 😉

All in all, this kit weighs in at 11 pounds. It’s a bit heavy to carry for a SOTA activation, but for POTA it’s no problem at all. I have indeed carried it up to a SOTA summit, but HF propagation conditions were poor and I was really struggling to make any contacts. Ended up resorting to activating on 2m with a tape measure Yagi. 😉

Because of the PALS webbing on the PRC-117G bag, this portable kit could be strapped to a larger backpack as needed, though typically I have just carried the kit inside my backpack, to keep the weight closer to my body. Perhaps more notably, additional accessory pouches could be attached, like a pouch for logbook/pencil/antennas/CW key etc.

Conclusion

So how is this kit to actually use? In a word, awesome. Drop it on the ground or on a table, deploy and attach an antenna, turn on the power. If I’m expecting to be on air for a long time, I can attach the solar charge controller and solar panel to keep the station running (though I have yet to do this while operating, since I completed this kit very recently). I can go out into the field and use this setup indefinitely, regardless of available electrical infrastructure.

For digital operations, I have a ToughBook CF-31 which is fully configured with all relevant software I’d typically use. This is great for tossing in the vehicle for a POTA activation, and even feasible for SOTA if you’re in great shape or willing to carry the extra weight. An alternative for digital ops could be a lightweight single-board-computer, tablet, or netbook, of course.

Just for fun, here’s a map of most of the QSOs I’ve made with this rig since putting it together. It’s not exhaustive, but what I could quickly gather up for this post. 133 contacts across 11 countries. The furthest contact thus far is with VK2WN on 30m FT8, at a nice 11965km (7435mi) distance, with just 5watts of output power on my side. Nice!

If you have any questions about this kit or would like additional details, please feel free to reach out. I’d also be curious to hear from anyone who follows this build and creates their own variation!

A Trailside, Low-Impact, Knee Board POTA activation at the Carl Sandburg National Historic Site!

9 Comments

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!

We found a park bench a mile up the trail and decided to set up there. Continue reading A Trailside, Low-Impact, Knee Board POTA activation at the Carl Sandburg National Historic Site! →

Getting To Know You Series: The Elecraft KX3–My thoughts, notes, and one extreme QRPp contact!

16 Comments

I’m very fortunate in that in the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

Over the years, I’ve written formal reviews about most of the field radios in my collection. In those reviews, I try to take a wide angle view of a radio–to see how it might appeal to a number of types of operators. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

The Getting To Know You series gives me an opportunity to highlight one radio at a time and showcase what I love about it and why it’s a part of my permanent radio collection. After we spend a bit of time talking about the radio, we’ll do a park or summit activation with it!

The Elecraft KX3

I was originally introduced to the Elecraft KX3 at the 2011 Dayton Hamvention–over a decade ago at time of posting!

I was commissioned to write a review of the KX3 for the Monitoring Times Magazine and Elecraft was kind enough to lend me a brand new KX3.

At the time, there was nothing like the KX3 on the market and I felt like I’d just received a radio from the future.

The KX3 offered 160-6 meter general coverage with an optional 2 meter module, ATU, internal AA battery compartment, and roofing filters. The controls were top mounted and current draw in receive was as little as 150 mA. At the time, there was no other radio on the market that could compare with the KX3’s field prowess.

But it wasn’t just its field design that was impressive.

In fact, when Rob Sherwood tested the KX3, it placed at the top of his list which is sorted by Third-Order Dynamic Range Narrow Spaced.

This field radio sported a bullet-proof front end and true contest chops, displacing $10,000+ high-end rigs.

Today, the KX3 (at time of posting) is still number 12 on Rob’s list. An impressive feat!

Herein lies the danger of doing reviews…

I didn’t have the KX3 in my grubby little hands for more than a few hours when I decided I had to buy one. I sold some gear to free up money and I bought the KX3 Elecraft sent me on loan for the full price.

I’ve taken this KX3 on numerous activations and on international travels. It’s a brilliant QRP companion.

These days, it’s in the shack more than in the field because I keep it hooked up to my KXPA100 amplifier. I feel like the KX3/KXPA100 combo is like having a poor man’s K3. As a huge bonus, the KX3 takes up little space on my table and the KXPA100 sits on a shelf–the overall footprint is much smaller than a K3 or K3s. It’s like having a remote head on my desk and works perfectly for my limited space shack.

The KX3 is a stellar, benchmark field radio, so it was great fun to feature it in this video.
