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

21 Comments

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?

The Best Ham Radio Hack: Re-Reading Your Radio Manual

11 Comments

Yesterday was one of those rare days where I had no pressing reason to leave the house—other than the temptation of a POTA activation. These days are a rarity, and honestly, staying home often wins out. As much as I love POTA, it’s also nice to settle in and simply enjoy being at home.

Yesterday afternoon, I deployed an EFHW antenna outside and tinkered with digital modes I hadn’t used in a while—mainly FT8, FT4, and PSK31. I connected my IC-705 to my MacBook Pro over WiFi using the excellent SDR-Control app.

When the cold started to bite (14°F/-10°C with a brisk breeze), I retreated indoors to my warm shack. With a mug of hot chocolate in hand, I performed a small ritual I repeat every few months as part of my field radio workflow:

Re-reading the manual

That’s right!

You’ll be seeing more of the Currahee soon!

I typically have a particular radio I want to revisit. Yesterday, I focused on the KH1 and the MTR-3B, as well as the new Currahee (see above).

Recently, while using the KH1 in the field, I couldn’t recall how to move between CW message memory banks (M1, M2, M3 and M4, M5, M6). Even though I know this radio well—since I’m in the testing group, it’s one I’ve explored extensively—I had a mental blank. So, I grabbed the manual, found the answer, and practiced the process until it felt second nature again.

After that, I skimmed the manual cover to cover. I didn’t read every single word but focused on pages that covered features I rarely use during POTA or SOTA activations.

Every time I do this, I learn something new.

I decided to make a short video about this habit of mine and why I think others should give it a try (see below). I get so many questions from readers about how to operate their radios—often their only radio—and it’s clear that many haven’t opened the manual since unboxing their rig. Instead, they rely on Google or YouTube for answers.

When someone asks me how to perform a specific function, I don’t want to sound grumpy by saying, “Read the manual!” Instead, I point them to the exact page they need and encourage them to read the entire manual. It doesn’t take that long and there’s a reward in the end.

Here’s the thing: when you invest in a high-quality transceiver, you owe it to yourself to fully explore its functions and features. Why not maximize your “return on investment” by understanding everything your radio is capable of?

Reading the manual isn’t just about solving immediate problems—it’s about discovering hidden gems that could enhance your experience on the air.

On the Ham Radio Workbench Podcast, we’ve talked about this very topic, and it turns out I’m not the only one who re-reads manuals regularly.

So, do you ever revisit your radio manuals? Have you found this practice helpful? I’d love to hear your thoughts—please share in the comments!

W7UDT: “Velcro, ergo; ergonomics…”

5 Comments

Many thanks to Rand (W7UDT) who shares the following guest post:

Velcro, ergo; ergonomics…

by Rand (W7UDT)

Velcro is amazing. It’s so handy. There are so many uses, and creative solutions it provides us. It’ll stick this to that, and that to this. As field operators, it should be part of our kits.

Below are some examples of how I’ve used Velcro.

Question: How do you keep a Android tablet, a 3aH 12v DC pack, a QRP Labs QDX LoBander, all its cords & patches, plus an EmTech ZM2 tuner all nice and tidy? Velcro!

Here’s the old QDX kit…

Here’s the new (velcro’d) QDX kit, complete with EmTech ZM2 tuner, neatly attached on the back of the Tablet, with the QDX and DC Pack. It all fits in a zippered pouch, along with the EFλ/2 antenna, perfect for the QDX.

The new QDX kit even sits at a nice viewing angle, with all of the cords hidden from view. Ergo, ergonomics.

Question: Where & how do you safely place your transceiver on a rugged SOTA/POTA activation, so it won’t get damaged?

How? Velcro! What makes more sense? A precarious rock, or the Molle patch on your pack?

This is my QCX Mini ~ Forty, Velcro’d with two horizontally applied 1” strips, with short cords channeled between them. It secures the perfectly mated 3aH 12v TalentCell battery, to which I applied another velcro strip to hold fast the Palm Pico paddle. Also note the ‘D-shaped’ earpiece/speaker, on the BNC jack. It’s hung and velcro’d just above the paddle.

Since this photo, I’ve added three 2×4” (cut to fit) patches to the front, back and bottom of the QCX Mini & TalentCell, which neatly bundles this little QRP contraption and transforms it into a QRP wonder! Now it all fits in my hand, or attaches firmly to my pack. Dit dit dit daw! Velcro!

A view from Zion NP, in the backcountry… late last Spring. Where my little transceiver tried to commit suicide.

Just sayin’… Velcro may be just the answer you’re looking for.

CW POTA: Steve’s simple clipboard mod for super-stable field keying

8 Comments

Many thanks to Steve (W4JM) who writes:

Here is what I use for POTA activations to keep the key stable.

A clip board, carpet tape on the back to hold a carpet pad in place.

The Begali I put two slots in the clip board on either side of the traveler where then I could use a tie wrap to pull it secure to the board.

On the CW Morse I just used two screws with locking nuts to secure it to the board.

Your right hand holds the pencil while sending and your wrist weighs down on the clip board and I printed some POTA logs on excel to fit to the left of the key.

I hope this helps some of your readers with key movements. I now have my left hand to drink my coffee.

Clever and simple! I love it, Steve. Thanks for sharing!

Fred’s simple hack to secure the Begali Traveler

7 Comments

Many thanks to Fred (KE8TBM) who writes:

Here is a solution I came up with for the slipping issue with the Begali Traveler.

It’s very easy to push a pin through the (front only) plastic/rubber feet on the key. This will stop it from sliding on everything including formica counter tops.

After you push the pin through the plastic/rubber feet using a needle nose pliers, simply snip the sharp end off to leave it blunt.

You can leave the little ball on the other end of the pin to retract it if you wish, however, I’ve found that not to be necessary. —-I find that the pins really don’t snag on anything as they just barely peak out the bottom of the foot, but the option is there.

This makes for a rock solid hold on your surface and is a game changer. It’s so nice to be able to push away and not worry about the key slipping around.

Mike, K8MRD just did a review on the Traveler Lite and mentioned the slippage issue.

Best 73 Thomas and thank you for being a great image for the ham community.

Fred, KE8TBM

What a simple and effective idea! Thanks for sharing this tip with us, Fred. Also, thank you for the kind words, OM.

Field Report: Testing the bhi Dual In-Line with the (tr)uSDX, making a big blunder, and P2P with Teri!

10 Comments

On March 30, 2022, I took my factory-assembled (tr)uSDX transceiver on a POTA activation at South Mountains State Park.

It was a “test flight” of sorts since I’d only had the (tr)uSDX for a few days and had not taken it to the field.

I wrote up an assessment from that initial POTA activation mainly to give other potential (tr)uSDX owners an idea of how well one of these super-affordable radios might perform.

Difficult to critique

It’s difficult to critique a 5 band HF radio that you can purchase as a kit for less than $100 and fully-assembled and tested for less than $150…shipped!

On the one hand, I think it’s one of the most amazing portable HF radio innovations of the past decade. It simply blows my mind that the developers (DL2MAN and PE1NNZ) could make this modest radio hardware do so very much. It’s truly a triumph of engineering and a fun little radio.

On the other hand, this isn’t a high-end radio, so we can’t expect performance like we’d see in an Elecraft, Icom, or Yaesu field radio, for example. I never expected this, in fact, but was very curious if the performance would be “good enough” for POTA or SOTA.  So many had asked me about buying a (tr)uSDX as their dedicated POTA radio.

I found using the (tr)uSDX for POTA was actually quite fun, and I certainly achieved my goal of activating a POTA park with it.

So yes, it’s good enough!

That said, I haven’t reached for the (tr)uSDX to do POTA or SOTA since last March because I prefer the performance characteristics of my other radios.

My biggest complaint, frankly, is that the audio fidelity is pretty poor. The noise floor of the (tr)uSDX is higher than most HF radios and audio amplification is very basic. I notice a lot of electronic noises (pulsing, etc.) in my unit. I find it a bit fatiguing to listen to for long sessions with my headphones. The internal speaker isn’t really a viable speaker for doing an activation–it’s more akin to an emergency speaker, if anything.

When plugged into an external amplified speaker, the audio is much improved. The pops and internal noises are still there, but it has better overall fidelity and the volume can be raised enough to hear weak signals (this can’t be easily done via the internal speaker).

It struck me that a DSP device might clean up the (tr)uSDX’s audio and noise floor a bit.

Enter the bhi Dual In-Line DSP filter

Sometime during the beginning of the pandemic, I reached out to bhi Noise Cancelling Products and asked if I could test one of their DSP units as a loaner. I’ve always felt that bhi manufactured the best DSP products in the amateur radio market.

At the time, I wanted one of my friends and contributors on the SWLing Post blog to test the bhi unit and see if it might help out a QRM situation that popped up at his QTH. I thought it would make for a great evaluation since I have little to no QRM at my home.

Graham, at bhi, kindly sent me a unit–the Dual In-Line Noise Eliminating Module–and as I prepared to forward it to my friend, his noise was no longer an issue. I can’t remember the details now, but there was no need to send it to him.

I notified Graham that I would like to test it myself, but that my plate was so full it would take time. What ended up happening, though, was I completely forgot about it due to a busy family life at the time.

I re-discovered the unit this year and spoke (apologized) to Graham at the 2023 Hamvention. Of course, he had no issue at all and was very forgiving. He’s a great fellow.

I thought pairing this bhi DSP unit to the (tr)uSDX would be a great way to, perhaps, cut down on the listening fatigue.

Fort Dobbs State Historic Site (K-6839)

On Wednesday, July 5, 2023, I had an opportunity to test the (tr)uSDX/bhi pairing at Fort Dobbs State Park. Continue reading Field Report: Testing the bhi Dual In-Line with the (tr)uSDX, making a big blunder, and P2P with Teri! →

Are you prepared for Radio First Aid?

10 Comments

by Vince (VE6LK)

(As is Vince’s usual, this article has a bunch of links – click on as many as you wish for the full experience)

Before I go too far into this topic, I wish to first offer hearty congratulations to Thomas Witherspoon for having one thousand posts on QRPer.com! Woo-Hoo!

Do you pack a Radio Field First Aid kit?

On my recent trip to VE3-land I had a few opportunities to practice set-up with my gear–away from the safe place that is my truck–to ensure I’d brought everything for my trip to Hamvention and activations along the way. I did forget an audio cable, however a visit to a local dollar store solved that problem inexpensively.

So, unless you pack two of everything -because two is one and one is none– you should expect that something’s going to fail or break along the way. What you never know is when or how that’s going to happen. I wouldn’t be writing this story if it had not happened to me before.

This time it was on a Sunday outing to VE-1512, the McLaughlin Bay Reserve Wildlife Area in Oshawa Ontario and far away from the comforts of my shop at home. Tucked away not far off of the 401 Highway, this nature reserve is a calm and peaceful oasis just minutes from urban life. I saw kayakers, hikers and trail runners during my visit.

Setting up my Comet HFJ-350M, I added the jumper cable to set the antenna for 20m and then I started to push the antenna down into the ground onto the stake. And that’s when my hand slipped and I broke the jumper cable connector, busted off in the hole.

Broken pin that triggered my outward potty mouth

QRPer Notes: Phil’s Field Antenna Survey Results, Gripping the Palm Pico, and 70’s/80’s Vintage QRP Radios

6 Comments

Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format.  To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!

Field Antenna Survey

Many thanks to Phil (KA4KOE) who shares the results from an informal survey he conducted on the POTA Facebook group. Phil writes:

Tom

I’ve let the survey run for about 3 days on the POTA Facebook group. Sample size was 658 votes. I opted to do a “type” survey and not by manufacturer.

Results:

    1. End Fed Half-wave: 25%.
    2. Shortened vertical with loading coil: 20%.
    3. Full-size vertical antenna / Hamstick style vertical with helical coil:12% each.
    4. Full-size dipole/doublet, etc.: 10%.
    5. End Fed Random Wire: 9%.
    6. Screwdriver motorized coil antenna: 3%
    7. Something tossed in tree and just hoped it would work: 2%

Total: 93%.

Remaining obscure types cut-off below 2% accounted for 7%.

Again, like the poll I conducted previously on radio types, not surprised by the No. 1 spot.

What DID surprise me was #7: I put that selection in the poll types as a joke but 2% of hams throw a wire up in a tree or other support with no forethought and hope it works.

The Palm Pico: Getting a grip!

Many thanks to Terry (N7TB) who shares the following tip:

Hi Thomas,

I was looking at your post re: the Pico Paddle.

I have both the single and double Pico paddle and the KX3 mount. After watching you hand hold your paddles, I came up with a way to make small paddles easier to hold. I have attached a photo. It is a small piece of 3/8 ID pipe insulation to make holding the Pico paddle easier.

Have a great trip to Hamvention.

73,

How to optimize low solar activity days for your activations

13 Comments

by Vince (VE6LK)

(As is Vince’s usual, this article is full of educational and fun links – click on as many as you wish)

Picture this ..  you are getting a bit twitchy due to lack of POTA activation and you have run out of Potaxxia. Further, You publicly stated a New Year’s eve goal to make at least 200 POTA CW activation contacts per month for 2023 (there may have been beer involved), and now you must stay accountable to your goal and you are currently behind plan. It’s too early in the season to be lawn mowing while listening to podcasts such as QSO Today, Ham Radio Workbench, ICQ Podcast, AP/DZ or Soldersmoke. Thus, chasing contacts is [always] a good use of your time.

Lastly, if you are like me, the the solar indices are still an art form being learned and the numbers for today aren’t all in the green zone.

One of many charts that help decode the magic behind propagation values – click through for source webpage

So you begin to wonder just how much effort it’s worth to load up your gear and try to activate. You think to yourself that there won’t be much action on bands other than 20m which has been noisy lately, so why bother as it’s at least a 45 minute trip to the nearest POTA entity.

With this background, on Saturday I placed myself in the city at the nearest-to-home spot I could park in the south part of Calgary adjacent to VE-5082, the Trans-Canada Trail. I was trying to make the best of what I perceived to be a rough conditions day and had no real plan except a convenient location requiring minimal effort for a minimal return. My expectations were, sadly, met in this regard.

The author in a suburban and *very* RF noisy place that he won’t return to.

I was at the edge of suburbia with large homes on my left overlooking the ravine and pathway on my right. To say it was RF noisy would be a colossal understatement. I made 18 painful contacts in an hour and I’m sure people called me but I didn’t hear them given the S7 noise floor on 20m. At least I made one DX contact to Denmark along the way. Overall feeling frustrated, I went back home.

Sunday morning rolls around and again I wonder “is it worth it”?
