30 Meters with a 4 Foot Whip–? Impromptu POTA Hunting with the Elecraft KH1!

10 Comments
My Elecraft KH1 packed in a Pelican Micro M40 case. This protects my KH1 while traveling around in my EDC backpack.

On Friday, December 8, 2023, playing POTA was not in the plan.

I needed to finish a field report, publish it, then attempt to make a dent in my email and comments backlog. Lately–as you might have noticed–it’s been difficult to keep up with everything.

That morning, I dropped off my daughter at her robotics class, then made my way to the Mills River Library and municipal park.

I arrived at the park around 9:20 AM, parked my car at one of the free EV charging spots, then walked to the library front door only to discover a sign that said they’d be opening an hour late (10:00).

All of the sudden, I had 40 minutes to kill.

Since my Elecraft KH1 now lives in my EDC backpack full-time, I thought, “Why not hunt a little POTA?”

I started walking to the baseball field to set up then turned around, went back to the car, and grabbed my action camera. I mean…why not film this session since the camera was in the car trunk/boot? Right–? Right!

POTA Hunting!

Keep in mind that the Elecraft KH1 is designed to operate on 20, 17, and 15 meters using the 4 foot whip antenna (assuming you have the internal ATU option).

This was awfully early in the morning for any of those bands–I knew 20 meters would be my best bet of the three.

I tuned around, but I couldn’t hear or work any of the handful of activators on 20 meters. They were all outside my 20M propagation footprint–most were simply too close for 20M.

Then I noticed my buddy, John (AE5X) spotted on the 30 meter band.

For kicks, I tuned down to the 30 meter band, found a clear spot, then hit the ATU button. I was surprised to achieve a 2:1 match!

What?

Of course, a decent impedance match doesn’t equate to efficiency. Then again, what did I have to lose? Nothing…that’s what!

I called John once, but another strong station caught his attention. Once he finished that exchange, I called him again and he replied! Woo hoo!

I suspect my effective power output was around 1-2 watts, but it was enough to make an exchange with John, so I was a very happy camper.

I also tried to work KD8IE on 30 meters, but could not punch through the strong signals from other POTA hunters.

By chance, though, I heard my buddy Eric (WD8RIF) calling CQ POTA just below KD8IE.  I could hear Eric because I had my filter wide open–as in SSB wide.

I tuned  down, called him and he came back with my call and a question mark after two tries.

We exchanged details, sent 72, and logged each other. What fun!

I found out later that my signal level was actually fine on Eric’s end, but I was *almost* outside of his CW filter edges. He struggled hearing me because I was too far from his centered frequency. I didn’t notice this on my end, of course, because I had my filter so wide open.

I’ve learned from this: next time I’ll narrow my filter before hunting stations. The majority of activators do not run with their filters wide open like I do.

By the way, if you’d like to read Eric’s field report from that same time frame, click here.

30M on the KH1 whip!

I’m pretty sure Elecraft wouldn’t recommend using your KH1 on 30 meters with the whip only because of its low efficiency, but I also know the KH1 will have no problem dealing with the 2:1 match. I bet you’d get an even better match if you lengthen the counterpoise–I simply used the supplied 13′ wire.

Of course–and again–30M on a 4′ whip is not an efficient antenna system, but it’s efficient enough to make some contacts! As my buddy Kurt (NT0Z) says, “RF gotta’ go somewhere.”

I will check in with N6KR and see what he says about this setup.

Library time

Post activation, I found a comfy spot to work in the library and published a new field report.

It struck me that no one passing by would have ever guessed that I had a full HF station in my backpack! For just a moment, it made me feel like an unassuming Cold War spy!

Oh yeah, the backpack: I took advantage of a Black Friday sale at Trakke and purchased the Bannoch Backpack I’d been eyeing for weeks–the discount was deep!

I justified this purchase knowing that I was doing my bit to support the economy of Scotland! Ha ha! Seriously, though, I do love this backpack.

Thank you!

Ham Radio Workbenches On The Air (& POTA): A short field report and a very long activation video!

3 Comments

Many of you know I’m on the crew of the Ham Radio Workbench podcast. In fact, as of this month, I’ve been there a year now (my how time flies).  Although it shows a certain lack of judgement on their part, I’m glad they invited me on board!

On October 9, fellow HRWB crew member, Mark (N6MTS), pitched an idea to us via email:

“What do y’all think about doing an HRWB On The Air event?”

We all agreed it sounded like a great idea. Things like this normally take a year’s worth of planning, promoting, and organizing. Not when Mark’s in charge, though.

Next thing we know, Mark had us sorting out the best date/time (December 3, 2023/1800-22:00UTC) for HRWBOTA and even reached out to some amazing volunteers who helped put together a website and spotting page.

Holy cow!

December 3, 2023

I planned to operate the entire four hour event period from Lake James State Park (K-2730) since it would be an easy detour en route to Hickory, NC (where I was staying that night). Of course, each contact would could for both HRWBOTA and POTA.

The previous day, however, I learned that one of my daughters had a meeting in downtown Asheville from 18:00-19:00 UTC. She doesn’t have a driver’s license yet, so I had to take her. Had it not been an important meeting in advance of her finals, she would have skipped.

This really threw a wrench in the works. I knew that by the time her meeting ended and I dropped her off at the QTH, the earliest I could be at Lake James was 20:15-20:30 or so.

How could I increase my on-the-air HRWBOTA time?

KH1 to the rescue!

Since the Elecraft KH1 was packed in my EDC bag, I decided to play a little HRWBOTA in the parking lot behind the meeting building.

I wasn’t sure what to expect to be honest. I wasn’t spotting myself anywhere but the HRWBOTA spotting page, and I was limited to the 15, 17, and 20M bands with the KH1’s 4′ whip antenna.

I spotted myself, hit the air and started calling CQ HRWBOTA!

In the span of about 45 minutes, I managed to log a total of 15 stations! Not bad considering I was standing in an urban parking lot, swimming in QRM, and going QRP!

I didn’t make a video of this part of the HRWBOTA activation–sorry about that if you worked me then. I needed every moment of on-the-air time I could grab. Here’s my log sheet:

Lake James State Park (K-2739)

I legged it to Lake James after my daughter’s meeting–in fact, to save time, I started my activation video while I was still in my car driving on I-40.

I arrived at Lake James, parked, plugged in the car, grabbed my gear and made my way to the picnic area next to the lakeshore. It wasn’t hard to find a site with a tree that might support my KM4CFT 30/40M linked EFHW antenna.

I include the full antenna deployment and station set-up in my (rather long) activation video below. Continue reading Ham Radio Workbenches On The Air (& POTA): A short field report and a very long activation video! →

SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit!

12 Comments

A few weeks ago, I mentioned that Jonathan (KM4CFT) sent me one of his new QRP end-fed half-wave/random wire antenna kits.

When my friend, Alan (W2AEW), caught wind that I planned to buy some 26AWG wire for this build, he sent me a spool of wire from a large reel he’d recently picked up at a hamfest.

What a nice guy! The blue wire is absolutely ideal for portable antennas.

Being the nice guy he is, Alan actually published a video about building Jonathan’s antenna kit on his YouTube channel. I highly recommend watching it!

Before I received the kit, I already knew what type of antenna I’d build: a 30 meter end-fed half-wave (EFHW) linked with a 40 meter extension. This antenna design has been on my mind for some time and Jonathan’s kit was the perfect excuse to build one.

Why a 30M EFHW with a 40M extension? Because a 40M EFHW gives me excellent SWR matches on 40, 20, 15, and 10 meters without needing an ATU.  A 30M EFHW gives me matches 30 and 17 meters.

Thus, with one linked wire antenna, I can cover 40, 30, 20, 17, 15, and 10 meters! That’s a lot of bands!

And since the antenna needs no extra matching, it’ll work with my transceivers that lack an internal ATU.

The Mountain Topper MTR-5B I acquired earlier this year.

In fact, I originally thought about this antenna design to use with my Mountain Topper MTR-5B which covers 40, 30, 20, 17, and 15 meters.

I built this antenna by first trimming it for a 1:1 match on 30 meters including a loop and strain relief to attach the extension.

When I was satisfied with my 30M EFHW, I then made the 40M extension, attached it to the 30M section with 2mm bullet banana connectors, then trimmed the antenna for a 1:1 match on 40M.

I spent the better part of 60 minutes trimming this antenna. I feel like patience really pays off because it’ll set up the antenna for good matches on all of the upper harmonics. Admittedly, I was a bit pressed for time that day, so I only tested this antenna in one configuration (an inverted vee shape) so hadn’t checked the SWR as a sloper or vertical.

My advice is to aim for a 1.3:1 or better match on 30M and 40M–that should be very doable if you wound your transformer correctly.

This was my first attempt at making in-line links, so I wouldn’t consider link my method as a “best practice”–rather, check out K7ULM’s guidance for making in-line links. Continue reading SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit! →

Video: Comparing the Elecraft KH1 with Mountain Topper Series QRP Transceivers

7 Comments

A couple weeks ago, I posted a video where I compared the Elecraft KH1 and KX2;I mentioned that it was the most requested comparison I’d received after I started taking the Elecraft KH1 to the field.

The second most requested KH1 comparison focused on various Mountain Topper series models: the MTR-3B, MTR-4B and MTR-5B.

That’s what we’ll take a look at in the comparison video below!

Basic KH1 ($550)

So when folks have asked me how the KH1 compares with a Mountain Topper, I think of the basic KH1 ($550 US) package, not the ($1100 US) “Edgewood” package like I have.

Why?

Without the Edgewood package, the KH1 lacks the internal ATU, coils for the whip antenna, internal battery, internal battery charger, logging tray, whip antenna, counterpoise, case, and attachable paddles.

In short, the basic KH1 is a 5 band CW-only radio, much like Mountain Topper series radios–in fact, a lot like my 5 band Mountain Topper!

This is why, in my video below, I base the comparison on the basic KH1 package which includes the KH1, power cord, USB cable, and manual only.

Video

I should note that this video primarily focuses on making a purchase decision–it’s not a receiver comparison or in-depth reviews:

Click here to view on YouTube.

A few notes…

The video above contains a lot more detail, but at the end of the day, you can’t make a “bad” choice here. All of these are fantastic radios for someone who enjoys ultra-light operating.

The Elecraft KH1 is more a more feature-rich transceiver; it has adjustable filters, attenuation, CW encode/decode, mini pan/scan, general coverage, SWR/power meter, more message memories, internal logging options (soon), user upgradable firmware, an internal speaker, and much, much more. On top of that, the KH1 can be upgraded to become a complete shack-in-a-box radio with internal battery, charger, ATU, attachable whip antenna, and attachable paddles.

That said, even thought the Mountain Topper radios are spartan in terms of features compared with the Elecraft KH1, they get the job done effectively. Their feature set is laser-focused on providing a SOTA activator everything they need in order to complete an activation and not a lot else. They will also operate effectively on the smallest of batteries and consume a mere 20-17 mA in receive–proper battery misers! For more of my thoughts of the Mountain Topper, check out my MTR-4B review and my “Getting To Know You” report on the MTR-3B.

Again, you can’t go wrong with a Mountain Topper or a KH1: they’re both made by fantastic companies and have a loyal customer base for good reasons.

Price

The Elecraft KH1 base model (40, 30, 20, 17, and 15 Meters) is $550, the complete, fully-loaded, “Edgewood” package is $1,100. They are currently on backorder, but Elecraft does note that they intend to start shipping again mid-January 2024. Click here for the latest news about lead times.

The Mountain Topper MTR-4B V2.

The LnR Precision MTR-4B (80, 40, 30, and 20 Meters) is the latest Mountain Topper radio and the current model at time of publishing. You can purchase these new for $369 US. LnR Precision builds roughy 25 per month when they have the parts. You will need to follow LnR closely in order to be updated when a production run is shipping. Each time units are offered, they’re snatched up in a matter of hours. You can find used Mountain Toppers out there, but pricing tends to be within 10-20% of the new price.

Thank you

I hope you enjoyed this little comparison video and that it might help you make a purchase decision.

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support.

Getting To Know You: The Yaesu FT-817/818 Series Portable QRP Transceivers

13 Comments

I’m very fortunate in that in the past few years I’ve acquired 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.

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 Yaesu FT-817 and FT-818 Series

As I mention in my “Getting To Know You” video below, my very first dedicated QRP field radio was the original Yaesu FT-817 (non-ND version), so it has a special place in my heart.

At the time, I was living in the UK and travelling extensively throughout Europe with my UK call (M0CYI).

The FT-817 hit the market and it blew my mind. Up to that point, there were no general coverage QRP radios on the market that small, that comprehensive, and that even sported VHF/UHF multi-mode coverage. It even had a small internal battery pack! What?!

I was an early adopter of this radio and travelled with it extensively–indeed, in all of the years I lived in the UK and Europe, the FT-817 was my only amateur radio transceiver.

Fast-forward to 2023–some 23 years later–and I still have an 817. Actually, I have two 817ND’s and one 818ND (although, I plan to sell one of my 817NDs soon–I don’t need three!).

I find the 817/818 to be an incredibly robust and capable field radio. It’s also a brilliant value–few radios offer you the capabilities of the FT-817/818 for under $700.

My FT-817ND in an Armoloq TPA-817 Frame.

Yaesu discontinued the FT-818ND almost exactly one year ago. Retailers no longer have new stock, but there are loads of them on the used market. Keep in mind that the FT-817/818 was a cash cow for Yaesu for over two decades–the used price remains fair because there’s just so much supply out there. I routinely see 817ND and 818ND models selling for between $375-700 depending on how they’re configured and what’s included.

If you’re looking for a comprehensive article about the Yaesu FT-817/818 series, I would encourage you to check out this piece I originally wrote for The Spectrum Monitor magazine.

POTA During a Beautiful Fall Afternoon at Tallulah Gorge State Park!

12 Comments

Sunday, October 15, 2023, was the final day of the W4 SOTA campout. That morning, Joshua (N5FY) and I packed up our tents/gear then played a little radio at our campsite (at Lake Rabun). We weren’t in a hurry because the morning was so enjoyable. In fact, I think we checked out not a minute before the dealine of 12:00 noon!

We both decided we wanted to squeeze in one more radio excursion before driving back to our QTHs.

Tallulah Gorge State Park (K-2202)

It wasn’t realistic to fit in another SOTA hike due to our schedules, but Tallulah Gorge SP was an easy detour for both of us.

We pulled into the park and queued up to to enter. The park was absolutely teeming with visitors that day. I would have expected nothing less on such a gorgeous Fall afternoon!

Joshua and I found a quiet picnic area–with a few picnic tables spaced apart from each other–near the lake shore. It turned out to be a perfect spot to play radio. We spaced our sites far enough apart so as not to easily interfere with each other while on different bands.

Joshua set up his KX1, a wire antenna, and used VK3IL pressure paddles.

Joshua deployed his KX1 next to the lake and I deployed my KX2 a bit further up the hill.

I paired my KX2 with my “no transformer” random wire antenna. Of course, I used a Tufteln antenna because, I mean, N5FY was standing right there! ?

This antenna consists of two 28.5′ 26AWG wires connected directly to a male BNC. Simplicity itself on the antenna side. It’s the KX2 internal ATU that does all of the matching (since there’s no transformer). I find that the KX2 can match this antenna from 40-10 meters with ease.

I think the magic of these simple random wire antennas is that they’re directly connected to the radio. There’s a bit of efficiency in having no line losses, etc. even if the ATU does soak up a bit of energy.

Time to hop on the air! Continue reading POTA During a Beautiful Fall Afternoon at Tallulah Gorge State Park! →

Postcard POTA Field Report: Pairing the KH1 with an EFHW at Pisgah National Forest

4 Comments

Welcome to another Postcard Field Report!

If you’ve been following QRPer.com and my YouTube channel for long, you’ll notice that I typically post two field reports with videos per week when my free time allows. Each report takes about four hours to produce along with a video. I’ve got a busy day ahead on the road (including a POTA activation), so in order to squeeze this field report into my schedule, I’m going to use my more abbreviated field report format: a “postcard” format!

Speaking of which….

Pisgah National Forest (K-4510)

On the morning of Friday, November 10, 2023, I had a couple hours to fit in some POTA time.

All morning, we had been receiving some much-needed rain in the form of scattered showers in a constant heavy mist.

I decided to explore picnic areas I hadn’t yet visited in Pisgah National Forest along the Pisgah Highway near Brevard, North Carolina.

I was curious if I might find a small shelter at one of the roadside sites. Unfortunately, I did not; however, I did find quite a few sites that were ideal for POTA with tall trees, space between picnic tables, etc. I decided to pick one at random that had no other park visitors.

I did have a small rainfly in the car I could set up, but I decided to simply risk it. The goal was to pair the new Elecraft KH1 with my (MW0SAW) End-Fed Half-Wave antenna.

I wanted to see if the KH1 ATU could match the EFHW on 30 and 17 meters (outside of its resonant bands of 40, 20, and 15 meters).

Setup

Since I wasn’t using the KH1 pedestrian mobile, I connected my N0SA (“SOTA paddle”) and my Anker Soundcore Mini portable speaker.

Antenna deployment was easy enough (though I did take a few tries to hit *the* tree branch I wanted)!

In no time, I had the KH1 on the air and ready to start calling CQ! Continue reading Postcard POTA Field Report: Pairing the KH1 with an EFHW at Pisgah National Forest →

The Elecraft KH1 or KX2? Which one should you buy?

19 Comments

Even before I started taking my Elecraft KH1 to the field and generating reports and activation videos, I started receiving questions from readers and subscribers about how the KH1 might compare with other field-portable radios.

At least 70% of all of these questions asked specifically about the venerable Elecraft KX2.

Making a purchase decision

I’m not surprised so many are trying to make a purchase decision between the KH1 and KX2.

For one thing, the KH1 and KX2 represent some of the smallest, most compact and lightweight shack-in-a-box HF field radios on the market. We’ve a lot of QRP field radios to chose from these days, but few have options for both internal ATUs, internal batteries, and attachable paddles. Very few are as light and compact as either of these two radios.

Another reason for the comparison is that many are in the long queue to purchase a new Elecraft KX2. At time of posting this article, if you place an order for the KX2, you are going to wait a few months for delivery.  The KH1 also has a lead time, but it’s likely shorter than that of the KX2 (check out the Elecraft Shipping Status page for more info).

Comparing models

While the KH1 and KX2 have a lot in common, they’re also quite different in many respects.

We radio ops like to compare features and specifications and Elecraft knew the KX2 and KH1 would be compared frequently, so they created a handy chart:

Click here to download Elecraft’s KX2 v KH1 comparison chart (PDF).

At the end of the day, though, I would argue that one’s enjoyment of a radio has more to do with how well it fits the operating style of the owner.

The KX2 is one of the best portable QRP field radios ever made, in my humble opinion. It’s a little high-performance machine that can handle any mode you care to use between 80-10 meters.

The KH1, on the other hand (pun intended), is designed to be an exceptional handheld radio for pedestrian mobile use and as a super lightweight, low-impact, field portable station. It’s essentially CW-only and operates on 5 bands (40-15 meters).

If you can be honest with yourself about how you plan to use the radio, it’ll help you make this purchase decision.

For example, if you never see yourself operating pedestrian mobile–you’re more of a sit down at a table sort of op–there’s a good argument to go for the KX2. If, however, you’re an avid SOTA/POTA portable activator who is primarily a CW op and you like the idea of a super quick deployment and handheld operating from anytime, anywhere, you should consider the KH1.

Video

To dig into this comparison a little deeper, I decided to make a video where I discuss the differences between the two radios and also speak to different styles of operating and which radio might suit that style best:

Click here to view on YouTube. 

I would be curious which radio you prefer and why. Please consider commenting!

Thank you!

I hope you found this post and video useful.

SOTA DX with a 20 Meter Delta Loop on beautiful Yonah Mountain!

3 Comments

I’ve taken a wide variety of antennas on SOTA (Summits On The Air) activations, but one wire antenna I’ve always wanted to deploy is a simple vertical delta loop.

This summer, I mentioned to my friend Joshua (N5FY) that I planned to build a delta loop antenna and next thing I know, he built one. I suppose he’d been thinking about adding it to his line of portable wire antennas at Tufteln.

I was planning to build a 20M delta loop fed with twin lead, but Joshua’s choice is better for multi-band operating. His 20M delta loop features a 4:1 transformer so it can be fed with 50 Ohm coax like my RG-316 (which is also easier to pack than twin lead).

You might recall that I used his 20M delta loop antenna at Holmes Educational State Forest (see photo above) in early September. It worked a charm and wasn’t too difficult to deploy (loops are obviously more finicky than a one wire end-fed).

The great thing about this loop is it’s resonant on 20 and 10 meters, and it’s quite easy to tune on 17, 15, and 12 meters with pretty much any ATU.

Fast-forward to Saturday, October 14, 2023 when Joshua and I were participating in the W4G SOTA campout in north Georgia…

Yonah Mountain (W4G/NG-048)

It rained cats and dogs Friday evening into Saturday morning.

Fortunately, most of the rain stopped by the time I surfaced that morning.

Joshua and I ate a quick breakfast, grabbed our SOTA backpacks, then drove to the Yonah Mountain parking area/trailhead.

Last year, we also activated Yonah Mountain as well, but underestimated the hike and our timing. We ended up being a good hour or so late to our SOTA evening potluck. This time, we were keen to spend more time on Yonah Mountain and get back to the campsite in plenty of time to join everyone for dinner (and share exaggerated stories about our SOTA adventures).

Last year, we arrived at the trailhead and it was parked full. This year, even though we arrived in the morning and even though it was incredibly foggy/misty, it was still quite full!

Yonah Mountain is an incredibly popular destination.

Another fun fact about Yonah: it’s not really a beginner’s summit despite the fact it’s so popular with hikers and runners.

It offers up proper elevation change, gnarly trail portions, steep inclines, and about four miles of trail round trip. Although not an incredibly long hike, it’ll give you more of a workout than you might think first blush.

We reached the summit in due time and set up our stations about 30 meters apart.

The whole time, I was also monitoring the partial solar eclipse we were having that day.

I brought along some solar eclipse glasses and ended up sharing them with everyone on the summit. It worried me seeing so many young people staring at the sun with only their sun glasses or even–gasp!–with the naked eye. (I mean, weren’t they paying attention in science class–?) 🙂

At one point in the activation during the actual peak of the partial solar eclipse, I left the radio and did a little more sun-gazing. Continue reading SOTA DX with a 20 Meter Delta Loop on beautiful Yonah Mountain! →

Field Report with N5FY: Checking out the new N6ARA MiniSWR (and a sweet 9V battery) at Don Carter State Park!

5 Comments

I am catching up with field reports and videos from last month and, I must admit, it’s fun reliving these activations.

October was such a busy month, it’s all been a bit of a blur.

Because I have a second Thanksgiving meal to prepare this morning for my wife’s family, I need to keep this report short–which won’t be easy because there’s a lot to unpack here– so we’re going to attempt do another Postcard Field Report!

Postcard Report from Don Carter State Park (K-2171)

I mentioned in a previous post that I participated in the W4 SOTA campout last month. .

Part of the fun  of the campout was hanging with my good friend Joshua (N5FY) whom many of you know from his amazing Tufteln antennas and accessories.

On the morning of Friday, October 13, 2023, Joshua and I activated Rocky Mountain (W4G/NG-011), a beautiful 10 point summit along the Appalachian Trail.

That afternoon, we met with Joshua’s family briefly, then planned to head to a pub in Clayton, Georgia, where a number of the W4 SOTA campers were gathering.

Joshua determined we had just enough time to pop by Don Carter State Park (K-2171) for a quick POTA activation and still make it to Clayton in time. As a bonus, Don Carter SP has a number of covered picnic shelters, making set up in the dry quite easy (it was raining at the time).

For this activation, I used my Mountain Topper MTR-3B field kit that I had used during my SOTA activation on Rocky Mountain. In fact, it was the only radio kit I brought with me for activations that day.

Joshua lent me his Tufteln 40/20 meter linked EFHW antenna (we only used the 20 meter portion of it) and I also got to use a few other accessories that were still very new to me:

N6ARA MiniSWR Meter

One was my friend Ara’s latest creation, the MiniSWR meter. Ara (N6ARA) kindly sent me this production unit to test (at no cost to me) earlier in October.

I was very excited about this particular product because a few of my QRP radios lack a built-in SWR meter (my MTR-3B, MTR-5B, TR-35, and SW-3B to name a few). Ara’s MiniSWR meter is so tiny, it’s easy to carry even in my MTR-3B SOTA kit that’s built into a Pelican 1060 waterproof case. (If you’d like more details, I’ll be adding this MTR-3B kit to the Radio Field Kit Gallery soon).

As with all of Ara’s products, the MiniSWR works brilliantly, is very affordable, and is available as a kit or pre-assembled. Check it out at N6ARA.com!

Rechargeable 9V Batteries

Another new-to-me product was this USB-C rechargeable 9V battery originally recommended by Adam (K6ARK).

Being honest here: this battery sort of blows my mind!

When paired with super efficient QRP radios like my MTR-3B (which uses something like 18mA in receive), one charge will take me through as many as two or three full SOTA/POTA activations!

These batteries are insanely affordable too. You can buy two for $15 and change at Amazon.

When I purchased these, I also bought two 3S packs in a Prime Day deal. These 9V batteries work so well, though, I’ve yet to add PowerPoles to the new 3S packs. I prefer the size and ease of use of these 9V cells.

Set up

Joshua helped me set up in short order. We deployed the 20M EFHW next to the picnic shelter and Joshua kindly lent me his OSMO 2 Action Camera and Anker SoundCore Mini speaker so I could make a video of this impromptu activation.
