G7UFO’s Magnetic Case for the BaMaKeY TP-III Paddle

A few weeks ago, Neil (G7UFO) reached out to let me know that he has started producing and selling 3D-printed magnetic cases for the BaMaKey TP-III.

He generously sent me one to check out, and I have to say—it’s a great option if you’re looking for a simple way to protect your TP-III when tossing it into your field pack.

Here are a few photos—note that the TP-III magnetically attaches to the base of the case. While the bond isn’t super strong, it holds the key securely in place during transport. The cover also stays closed with the help of magnets.

I love his UFO logo!

As you probably know, one of my goals here at QRPer.com is to support independent ham radio makers—especially those who create and sell gear they personally use in the field. This case is an excellent option for TP-III owners in the UK, but Neil also ships internationally.

If you’re interested, you can purchase this case either fully assembled or as a magnet/washer kit if you’d like to 3D-print and assemble your own.

Should It Stay or Go? A POTA Activation with the Ten-Tec Argonaut V

On Wednesday, January 5, 2025, I planned a trip to Hickory to pick up my father and take him to lunch. With our family’s hectic schedule, I hadn’t been able to spend any meaningful time with him in weeks, so I was looking forward to catching up.

Of course, as is tradition, I also planned a POTA activation en route.

That morning, before leaving the house, I debated which park to activate: South Mountains State Park, Tuttle Educational State Forest, or Lake James State Park?

It had been a long time since I’d activated South Mountains, so I considered heading there. However, after checking their website, I was surprised to find the entire park still closed due to damage from Hurricane Helene. I hadn’t realized the storm had impacted the foothills that severely—though with miles of trails, it made sense that they were still working to clear blowdowns.

Next, I checked Tuttle, only to discover it was still closed as well. Wow…

I knew the Catawba River access at Lake James was open because I had activated it a few weeks prior. Sure enough, their site confirmed that the Paddy’s Creek area—the park’s largest section—remained closed. Wow.

Clearly, I had underestimated the damage these parks sustained after Helene.

So, I set my course for Lake James, hoping that, by spring, the other parks would reopen. No doubt, park staff were working hard to make that happen.

Another mission

I had a specific radio in mind for this activation: my TEN-TEC Argonaut V.

I bought this radio used almost four years ago and have been very pleased with it. I’ve always been a big fan of Ten-Tec, and to me, the Argo V embodies the super-simple design I loved from their late 1990s/early 2000s radios. It features a big LED display, a prominent encoder, and a proper fold-out bail underneath—a solid legacy field radio.

What I love most about the Argo V (and Ten-Tec radios in general) is its superb audio, low-noise receiver, and silky-smooth QSK.

The Argo V wasn’t built to be a power miser—the audio amplifier is beefy and a bit current-hungry (I believe it draws around 500mA in receive, and more with audio output). But the tradeoff? Outstanding audio quality. It’s the perfect radio for Field Day or long operating sessions when you want to avoid listener fatigue. It’s also a fantastic shack radio.

That said, because of its bulk—and my tendency to grab smaller radios for field use—the Argo V has primarily lived in my shack.

The Argonaut VI

Last year, I acquired a Ten-Tec Argonaut VI, the last Argonaut model Ten-Tec produced—one I helped beta test back in the day.

When I bought the Argo VI, I told myself I might let go of the Argo V at some point. I’ve been debating this ever since.

Lately, I’ve been actively downsizing my shack. I need to sell, trade, or give away radios I’m not using. I don’t like harboring “shelf queens”—I want my radios to get regular airtime. But since bringing the Argo VI into the shack, the Argo V hasn’t seen much action.

My friend Vlado (N3CZ) and I plan to sell gear at the Charlotte Hamfest in a couple of weeks. I figured this POTA activation might help me decide whether to sell or keep the Argo V.

So, with my Argonaut V and my Tufteln linked 40M EFHW packed, I made my way to Lake James!

Lake James State Park (US-2739)

That morning, Lake James was incredibly quiet. There were very few visitors—even though this was the only section of the park open.

Then again, it was early on a Wednesday morning, not exactly prime time!

I chose a picnic table near the parking lot since I was carrying the Argonaut V and gear in a storage box rather than a backpack.

My high-visibility ABR cable assembly.

I quickly deployed my End-Fed Half-Wave (EFHW) antenna and set up the Argonaut V.

Testing the TouchPaddles

Next, I hooked up my new-to-me TouchPaddles, a generous gift from a kind subscriber/supporter.

These keyers were originally sold as kits and have been discontinued for at least a decade. Though a bit bulky, it’s a fantastic CW accessory!

It uses capacitive touch paddles instead of mechanical parts. The added bulk and weight keep it stable while keying.

The unit also has built-in CW message memory. I haven’t programmed it yet (if you have experience with this model, let me know how!), but I plan to experiment with it soon.

The paddle has two output modes:

  • Standard paddle output (for radios with built-in keyers, like the Argo V).
  • External keying mode (for radios without built-in keyers or those with poor internal keying).

I used the standard paddle output since the Argo V’s internal keyer works brilliantly.

With everything hooked up, it was time to hit the air!

The Toughest CW Paddles for Field Use: What’s Your Pick?

Many thanks to Dale (N3HXZ), who writes:

“It would be nice to hear from your listeners/subscribers about which is the most robust paddle! I have not met a paddle yet that has not failed in the field at some point. Thanks for all your good work.”

This is a great question.

I feel that almost all of the paddles and keys I regularly take to the field pass muster.

Some of my picks

Note that some of the following links are affiliate links that support QRPer.com.

I’m a big fan of CW Morse’s $45 US 3D-Printed Pocket Paddle. I find it to be remarkably robust. I toss it in my backpack without any extra covers or protection, and I’ve never had one break. I also appreciate how easily adjustable it is in the field.

Similarly, the KM4CFT paddle seems to hold up well, though I haven’t owned one as long.

The CW Morse CNC Machined Aluminum Paddle is one of the most rugged paddles I own. This key is CNC-machined (except for the 3D-printed top cover), making it virtually bulletproof. A solid choice!

The BaMaKeY TP-III is another solid paddle. It’s not inexpensive, but I’ve never regretted purchasing one. When paired with the Senrog Bench Block, it becomes a stable tabletop key that won’t move as you operate. During transport, I use the Tufteln protective cover, though I feel this key could survive in a backpack with minimal extra protection.

While the VK3IL Pressure Paddle V2 doesn’t feel substantial in the hand–it’s a touch paddle built on a circuit board–it’s incredibly robust due to its lack of moving parts. It’s easy to protect in a pack, and there’s little that can go wrong with it. If you’d rather not build one yourself, Vince (VE6LK) has some excellent options.

At 298 Euro, the Begali Traveler is the most expensive paddle on this list. It’s also the heaviest. But if you’re looking for a larger, precision field key that’s robust, it’s hard to beat. The Traveler has folding wings that protect the finger pieces during transport and open when you’re ready to operate.

I love this key and take it with me when size and weight aren’t major concerns. Pair it with a Tufteln protective cover for ultimate protection in your field pack.

Your suggestions?

I’ve limited this list to keys I’ve taken to the field numerous times and have owned for at least a year. Of course, my experience is limited to the keys I own—there are so many others on the market!

In your real-world experience, what do you consider the most robust field keys? Please share your suggestions in the comments!

W8TMI’s Elecraft KH1 Field Kit

Many thanks to Tim (W8TMI), who shares the following article about his portable field radio kit, which will be featured on our Field Kit Gallery page.  If you would like to share your field kit with the QRPer community, read this post.


W8TMI’s Elecraft KH1 Field Kit

by Time (W8TMI)

My Elecraft KH1 field kit is split into two parts: the bag provided with the Edgewood package and a separate bag for added functionality. The Elecraft bag is set up to venture out by itself without anything else required for an activation. The additional bag provides a longer random wire antenna and the ability to get it up into a tree, which increases its gain over the stock whip antenna.

Pure POTA Fun: A Quick Two-Watt Activation with New Gear and a Vintage Pack

Wednesday, January 29, 2025, was a busy day, but that morning, I was yearning for a little POTA time. I carved out an hour in the late afternoon to play radio—just enough time for a quick activation on the Blue Ridge Parkway (US-3378).

I had two new pieces of gear I was eager to test:

  1. A BNC mini antenna clamp mount, designed by my good friend Mike (KE8PTX), for use with Elecraft AX-series antennas and other mini verticals.
  2. A vintage Swiss Army rucksack, a Christmas gift from a dear friend, beautifully restored by Jack Carter.

BNC Mini Antenna Clamp Mount

Mike designed this clamp to be lightweight, durable, and versatile—it can attach to more than just a tabletop. He’s even clamped his AX1 to tree branches! As with all of Mike’s creations, it’s purpose-built for field operators like himself.

If you have a 3D printer, you can print your own, or you can buy a professionally printed version from Joshua (N5FY) at Tufteln (links below).

A New Vintage Backpack!

This Christmas, I received a surprise parcel. When I opened it, I couldn’t believe my eyes—a vintage Swiss Army rucksack in pristine condition!

Many of you know I have a soft spot for vintage military packs, and this one is truly special. Jack Carter, who restores these packs, wasn’t sure of its exact age but estimated it to be from the late 1950s or early 60s.

Specs:

  • Internal aluminum frame
  • Water-resistant salt-and-pepper nettle canvas with leather straps and bottom
  • External flapped pocket (9 x 11 x 2 inches)
  • Adjustable leather shoulder straps
  • Main compartment (20 x 16 x 8 inches)
  • Weight: ~6 lbs

Jack meticulously documented the restoration process, including deep cleaning, six rounds of leather cleaning, twelve coats of leather conditioner, and two cans of Filson Oil Wax applied with a heat gun to protect the canvas.

The result? A cavernous, beautifully restored rucksack that will accompany me on many POTA and SOTA excursions. At six pounds, it’s a bit heavy for longer hikes, but for moderate treks, it’s perfect.

I chose the TR-45L for its first POTA activation because I’ve always felt the TR-45L has a nice vintage/nostalgic look to it. It and the pack pair nicely!

Setup

Setting up the BNC clamp mount was a breeze. Mike designed it with a dedicated attachment point for the Elecraft AX2’s 13’ counterpoise.

After securing the antenna, I used the TR-45L’s built-in Z-Match ATU to achieve a near-perfect SWR.

Note: Unlike the AX1, the AX2 is a monoband antenna. Mine is set up for 20 meters, though the coil can be modified for other bands above 20 meters.

With everything in place, it was time to hit the air!

A Sampling From My EDC Pack: Ten Essentials I Carry Everywhere

Last year, I mentioned—either in a field report or video—that I carry a full Elecraft KH1 field kit in my everyday backpack, my EDC (Everyday Carry) pack.

That led to a great question from Terry, a reader who was studying for his ham radio license at the time. He wrote:

“Thomas, thank you so much for the field report. I had never guessed a complete HF radio field kit [like the KH1] could be so small that it would qualify as a bonafide EDC.

I’m very curious—what other EDC items would you recommend, not just as a radio operator but in general? I suspect you’ve put some thought into this in the past.”

Great question, Terry! And my apologies for taking, well… several months to respond. Your message got lost in the shuffle when Hurricane Helene hit, effectively dropping an atom bomb on my inbox and free time.

To make up for it, I thought I’d turn your question into a proper post.

I Love EDC

Yes, I do put a lot of thought into my EDC items. I’m constantly on the go, and since I never know when I’ll have time to write a field report, review, or even catch up on emails, I take my work with me. My laptop (a MacBook Pro) is a key part of my EDC.

And, as you noted, so is my KH1 field kit. It’s safely packed inside a Pelican Micro M40, so I don’t have to worry about damage if I drop my pack or something heavy lands on it.

But if I understand your question correctly, you’re asking about the other non-radio-related EDC items I carry.

Another reader/subscriber recently (as in a few months ago) asked for a full video tour of my EDC backpack, and I do plan to make one soon. That said, I’ll need time to prepare because—frankly—I carry a lot of stuff!

For now, though, here are ten items that are always in my EDC pack. Most of these aren’t directly related to radio, but they’ve proven their worth time and time again.

(Note: Some of the links below are affiliate links that support QRPer.com at no cost to you.)

Item 1: Leatherman Signal Multitool

This is my go-to multitool. It features pliers, screwdrivers (with a bit collection), a knife, a saw blade, a whistle, a fire-starting flint, a bottle opener, and more.

I firmly believe every field operator should carry some sort of multitool—it’s indispensable for quick antenna repairs.

Item 2: Rechargeable Nitecore Headlamp

I’ve said it before: a good headlamp is as essential as a first-aid kit, especially if you hike to your radio sites. This is my favorite headlamp for EDC, though I have many others. The one in my SOTA pack has a beefier battery and a brighter beam, but this Nitecore is perfect for everyday use.

Item 3: First Aid Kit

I always keep a compact first-aid kit in my EDC pack. I typically build my own, focusing on cuts, scrapes, tick removal, headaches, stomach aches, and allergies. I keep a more advanced trauma kit in my car and a separate field first-aid kit in my SOTA/POTA packs.

Item 4: PD Battery Pack

This Anker power bank charges everything from my phone to my laptop. With a Tufteln converter, I can even power a radio in a pinch. It’s a must-have for keeping my gear running.

Item 5: Light My Fire Spork

This is one of the most useful things I carry. It’s lightweight, insanely durable, and much better than disposable plastic cutlery when eating a salad or soup on the go. Such a simple item, but incredibly handy. There are numerous options like this on the market (many in durable plastic) but I like this particular one so much, I bought a second for my wife. Makes for a great stocking stuffer.

Item 6: RF Connector/Radio Accessories Pouch

This small pouch holds an assortment of RF connectors—essential backups in case something in my POTA field kit fails. Because let’s be honest… something always fails at some point.

Item 7: Commando Precision Screwdriver Set

This little kit has saved the day more times than I can count. Unfortunately, I don’t think my particular model is still made because the company appears to have closed shop. Very unfortunate because it’s super high-quality and was made in the U.S.

You might still find them on eBay. I wrote this review on the SWLing Post five years ago.

Item 8: PackTowel

A compact, absorbent, quick-drying towel is endlessly useful—whether for cleaning up a spill, washing up, or drying off gear after a sudden rain shower. I carry this 14×10″ size.

Item 9: Victorinox Nail Clippers

This little Swiss Army tool is a gem. It has excellent nail clippers, plus tweezers, a toothpick, small scissors, and a tiny knife.

Small, simple, and super useful.

Item 10: Notepad and Pen/Pencil

I like taking notes, and this combo–a small Rite in the Rain pad and Graphgear mechanical pencil–is always within reach. It’s also my backup logbook when operating the KH1 in tabletop mode.

Bonus Item: Loop Ear Plugs

As I pulled items from my pack for photos, I realized one more essential: Loop Ear Plugs. A friend recommended them, and I got pairs for my daughters and me this Christmas. I’m easily distracted by loud noises when working, so I often use white noise or instrumental music for focus. I’ve also used cheap foam earplugs, but they aren’t comfortable long-term—especially for sleep.

These Loop Ear Plugs, however, are low-profile, lightweight, and so comfortable I forget I’m wearing them. They don’t block all sound, but they take the edge off loud, percussive noise while still allowing conversations. A game-changer for noisy spaces, for me at least!

So much more…

Honestly, it was tough picking just ten (okay, eleven) items. When I look in my EDC pack, I see so many things I wouldn’t want to be without. Most of them are compact, lightweight, and boringly practical—but they make life easier.

I’m setting a goal to film a proper EDC backpack tour within the next month. It’ll be a long video, but I think it’ll be fun to go through everything I carry.

Of course, I’d love to hear from you—what do you keep in your EDC?

Pre-Built VK3IL Pressure Paddles via VE6LK

If you’ve been listening to the Ham Radio Workbench podcast, you might have heard Vince (VE6LK) mention that he and VE6TD planned to order parts to produce a batch of pre-built VK3IL pressure paddles.

Well, I just heard from Vince that they have completed a limited run. Here are the details from the ordering page:

For a limited time, VE6LK and VE6TD are selling pre-built 4″ (100mm) long VK3IL v2 pressure paddles. They ship with a high-quality attached 4′ silicone cable with your choice of a straight-through or right-angle TRS plug on the end.

We are the only place you can buy one of these pre-built in North America. If you would rather order a kit, check out VK3IL’s blog [linked here] where he lists other places that sell kits. We are not selling kits, these are pre-built.

You’ll receive exactly the following:

    • Pre-built paddle with integrated 4′ silicone super flexible cable
    • Your choice of straight or right-angle plug on the end of the cable
    • Wrapped in black heat shrink tubing, padded on one side for comfort
    • Paddle is approximately 105mm (4″) long x 25mm (1″) wide x 9mm (5/16″) thick and weighs 28g (1 oz.)

We pre-test each and every paddle before it leaves our hands.

The price for each pre-built paddle, shipped to Canada or within the continental United States (CONUS), is $85 CAD or approximately $59 USD. I believe this is a fair price for those who prefer not to source the parts themselves to build a VK3IL paddle.

I must say that the pressure paddle design functions beautifully. It provides very accurate keying in the field and, so far, it has worked with every radio I’ve connected it to.

Elecraft KH1 Anytime and Anywhere Adventures

by Micah (N4MJL)

Anywhere and anytime—that’s how I like to describe my Elecraft KH1. This radio goes everywhere I go. As an airline pilot, I bounce from coast to coast and everywhere in between almost daily. Since I’m constantly on the move, my radio gear has to be small and compact.

I’m a third-generation ham radio CW operator. Anyone who’s heard me on the air knows I’m still quite new to CW. I only started running CW activations with POTA/SOTA in the spring of 2024. Here’s the gear that’s been working well for me, along with a few photos from the locations I’ve had the pleasure of activating.

I’ve found that the Pelican M50 micro case is the perfect “shack in a box” for my KH1. This setup goes everywhere with me. Here’s what fits perfectly in the M50:

  • Packtenna 9:1 random wire
  • 20 ft BNC coax
  • Panasonic ErgoFit earbuds
  • SP4 paddles from CW Morse
  • KH1 (fully loaded with internal battery and tuner)
  • 30 ft throw line
  • Write-in-the-Rain notebook
  • High Visibility Orange Cap-O-Matic Fisher Space Pen (with lanyard)
  • Desiccant silica gel pack

In pedestrian mobile configuration, the KH1 is a solid system. I’ve done several activations this way. That said, after 45 minutes of holding the KH1 in this setup, I’m ready to wrap up! Having a portable shack that lets me deploy a random wire that tunes 40-15m and a more ergonomically designed key drastically improves my capabilities.

In many urban environments where I activate POTA, pedestrian mobile is essential. Unfortunately, the security in urban parks can be unpredictable, and the KH1 allows me to operate on the go and quickly move if needed.

Some of you may be wondering what I did to the inside of my M50 case. Well, in my defense, it’s my wife’s fault. She left me unsupervised with a glue gun and a bit of alcohol. When my KH1 arrived this spring, solar conditions were poor, so I had a few days to think and decided to turn the case into a makeshift Faraday box. I used Polyken aluminum tape, cardboard, and a glue gun to line it. Now, I know what you’re thinking: there’s no electrical bonding between the lid and lower box due to the rubber seal, so will this really work as a Faraday cage? Maybe, maybe not—but it sure looks cool! What do you think?

In addition to the M50 case, I carry a support pouch (Magpul DAKA, size small). This heavy-duty, water-resistant pouch contains:

  • 31 ft counterpoise wire
  • AXE1 40m antenna extender
  • Bioenno battery 12V 3Ah (backup battery—“1 is none, and 2 is 1” if you know, you know!)
  • KH1 power cable
  • KH1 right-angle antenna mount

These items aren’t essential but are nice to have for longer activations.

When I’m done flying and ready to play radio, I pack all this gear into my Flash 22 day pack. This compact, minimalist pack takes up almost no room in my flight bag and even has a built-in whistle on the chest strap, which is perfect for California!

When conditions allow, I enjoy using the full five watts of power. My go-to antenna is the SOTAbeams Band Hopper III, which is a versatile half-wave linked dipole:

  • Rated 125 watts
  • Center-fed with 33 ft RG174 coax
  • Guying system included
  • Resonant on 20m, 30m, and 40m (no tuner needed, though the KH1 tuner will also tune up 17m and 15m)
  • Built-in balun
  • Weighs only 14 oz

The wire/guying winders are excellent, and I’ve used this system in all kinds of environments, from sandy beaches to mountain tops above the treeline. I replaced the aluminum tent pegs with plastic ones to keep TSA happier.

The SOTAbeams Tactical Mini Mast fits diagonally in my 22″ roller board. I wrap heavy rubber-coated wire around it to secure it to posts or shrubs when needed.

Along with this radio gear, I also manage to pack a change of clothes—usually enough for a five-day trip. I typically fly three trips a month, each lasting four to five days. My roller board carries me and my radio gear from plane to plane all week long.

On a short backpacking trip along the Appalachian Trail (June 3, 2024), I activated SOTA summit W4V/BR-007 Three Ridges and the Three Ridges Wilderness area (POTA US-9959). The mountain in the distance is The Priest (W4V/BR-002), which I activated earlier this year with my LNR Precision MTR4B.

The summit of Three Ridges is a densely wooded area, so I stopped below the summit to enjoy the view, grab a quick snack, and play some radio. I snagged two POTA-only QSOs with W8WZ in Louisiana and KU8T in Indiana using the KH1’s whip antenna. Once I reached the summit, I used the Packtenna 9:1 random wire for my activation.

The QRPworks “Key Line MagPi” for KX2 and KX3 now available for purchase

Many thanks to Shel (KF0UR) who writes:

Remember the swivel paddle platform for the KX2 & KX3 my partner Steve KB3SII gave you at Hamvention last May? Well, it’s finally in production and shipping immediately.

https://www.qrpworks.com/key-line-magpi-store.html

It comes configured for the KX2, but includes the parts for the KX3 (a screw and a spacer) which is a very easy change to make. And for non-magnetic paddles it comes with 3M Dual Lock to fasten it. I used it with a magnetic BaMaKey for 800 QSOs on Field Day last year with my KX3. It worked great for me and the other ops.

Thanks for letting us know, Shel! I really love this key bracket and am happy to hear it’s in production.

If you want to see it in use, here are two activations from July when I used a prototype of the Key Line MagPi:
