My first POTA Activation with the Index Labs QRP Plus Field Transceiver

16 Comments

Sometimes, we do things for the pure nostalgia of it all!

I mentioned in a previous post that I recently acquired a circa 1995 Index Labs QRP Plus transceiver. Being transparent here, this was an impulse purchase fueled by pure, unadulterated nostalgia.

The QRP Plus was the first QRP transceiver that I’d ever laid my eyes on only a month or so before obtaining my ham radio ticket in 1997. I’ll write about this in more detail in the future–and I speak to this in my video below–but let’s just say that this little cube of a radio made a big impression on me at the very beginning of my ham radio journey.

I thought it might be fun to take it to the field and compare this 1995 state-of-the-art radio with so many of my other field radios. The QRP Plus wasn’t a perfect radio, but it was a marvel at the time it was produced. I can’t think of a smaller, more battery-efficient general coverage 160-10M QRP transceiver at the time.

I was eager to introduce this little radio to the world of POTA so on the morning of Thursday March 21, 2024, I grabbed it and hit the field!

I called the Vance site that morning and learned that a large school group would be arriving around noon. Since I was planning to leave around that time anyway, it was perfect timing for me.

Since I hadn’t created a field kit specifically for the QRP Plus yet, I brought my watertight stackable Husky brand box that basically contains everything I need to set up a field radio station, save the radio.

I unpacked everything I needed: a key, key cable, battery, power cord, cable assembly, antenna, logbook and pencil.

Since the QRP Plus has no internal tuner, I paired it with my MM0OPX 40M EFHW antenna which would give me 40, 20, 15, and 10 meters. Note that Index Labs used to make an external manual ATU for this radio called the QRP Companion–I’ve never seen one in person, though.

Even though the Vance staff told me that the school group would not be using the picnic shelter, thus I could have free reign, I still deployed my antenna in a way that it would not become a trip hazard–keeping it close to the shelter and as conspicuous as I could (I do wish I would have brought along my flagging tape, but I left it at home).

Setting up the QRP Plus station was quick and easy. Time to hit the air!

Woo hoo! Finally taking my QRP Labs QMX on a POTA activation!

17 Comments

Those of you who purchased a fully-assembled and tested version of the QRP Labs QMX are, no doubt, patient people.

While you can order a kit version of the QMX and receive it fairly quickly (still, I believe), the assembled versions take more time as the QRP Labs crew is small and they build and test these by hand.

I ordered mine on June 5, 2023, and it shipped on December 27, 2023.

Truth is, I’ve had a QMX kit since Hans Summers announced it at Four Days In May (FDIM) prior to the 2023 Hamvention. I’ve been meaning to build it but, as many of you know, my life has been a tad crazy these past months and I never got around to it.

I purchased an assembled version of the QMX because I will be reviewing this one and wanted a factory-tested unit. I would have never guessed I’d receive the assembled unit before building it!

Familiar Form-Factor

The QMX looks so much like my QCX-Minis, I’ve gotten them mixed up in the shack! The menu system is very similar to the QCX, but there are some changes to accommodate band changes, modes, etc., as the QCX-Minin series is mono-band CW only.

The QMX, on the other hand, is a five-band, five-watt, multi-mode (CW, Digital, and likely SSB in the future) transceiver. It’s hard to believe you can purchase the QMX for as little as $90 (bare-bones) kit or $165 (fully-assembled and tested).

I initially thought I had an issue with my QMX because it kept shutting down the transmit function. Turns out, that was all user-error. I mentioned the issue on an episode of the Ham Radio Workbench podcast, and a couple of listeners wrote to tell me what I was doing wrong: I was feeding it too much voltage. The QMX doesn’t want more than 12V or so. If the radio detects even a temporary mismatch, it shuts down the TX to protect the finals, etc.

I was unintentionally triggering the QMX’s self-protection functionality!

Once I figured that out, I decided to simply pair my QMX with my Bioenno 3Ah 9V LiFePO4 battery. That would yield about 3 watts of output power and be a comfortable voltage for the QMX.

Vance Historic Birthplace (US-6856)

On Thursday, March 7, 2024, I finally took the QMX outdoors where it belongs! I had a one-hour window of time to complete a full activation. I decided to pair the QMX with my Chelegance MC-750 vertical.

My QMX is a “low-band” version that covers 80, 60, 40, 30, and 20 meters. I thought the top end of its band coverage would serve me best mid-day, so I planned my activation around 20 meters.

Setup was easy and simple. You can see the full set-up process in my activation video below.

A Slimmed-Down Solution: My first POTA activation with the Penntek TR-45L “Skinny”

9 Comments

You might recall a recent POTA activation where Jonathan (KM4CFT) joined me at the Vance Birthplace K-6856 US-6856–?

Jonathan used my Penntek TR-45L for his portion of the activation, and I was pleased he got to spend some time with this magnificent CW machine. You might also recall that it still had a buzz in the speaker audio–something inside the radio was vibrating.

KM4CFT working the TR-45L in late December 2023.

I tried to track down the buzz as Jonathan operated by tightening some of the screws holding on the speaker grill (yeah, I’m sure that was annoying, and he’ll think again before activating with me in the same space–!). I knew, though, it was something inside the chassis that was vibrating with audio.

As I also mentioned, my TR-45L was a prototype unit (I helped Beta test it)–it had a couple of mods and wasn’t exactly representative of the upgraded production model.

John (WA3RNC) at Penntek reached out to me after I published my recent field report and video; he offered to upgrade my TR-45L to the production chassis which would sort out the buzz. I was most grateful, of course!

He then asked if I would be interested in checking out the TR-45L “Skinny,” which is essentially a TR-45L in a much skinnier chassis. The Skinny model lacks the ATU and battery options but is lighter weight and more portable. I mentioned to John that I’d like to purchase one, actually. Since John was interested in sponsoring QRPer, we ended up working out a barter (at full market price) for ad space. I love this arrangement, actually, because I was going to approach him about sponsorship at some point anyway.

The Skinny!

Now keep in mind that the TR-45L is one of my favorite CW radios. I love the audio, the receiver characteristics, and the “Apollo era” aesthetic. I think it’s one of the best-looking and best-sounding radios on the market.

The Skinny is just like the bigger TR-45L, just roughly half the depth. I did have concerns that the audio wouldn’t be as good since the acoustic chamber would be smaller, but turns out, I had nothing to fear. The Skinny’s audio is on par with its bulkier sibling.

There was no learning curve with the Skinny because 1.) it’s identical in operation to my TR-45L and 2.) Penntek radios have super simple interfaces, and almost every function has a top-level direct control.

Zebulon Vance Birthplace (US-6856)

On Tuesday, February 27, 2024–the day after receiving the TR-45L Skinny–I packed it up and took it to the Vance Birthplace for its inaugural POTA activation!

That day, I had about 90 minutes to enjoy an activation, and I was looking forward to spending time with the new Skinny.

Vance was a great choice that day because the weather was moody; it was gusty, rainy, and I knew their picnic shelter would provide excellent cover.

The Skinny (in its padded bag), the MC-750 and my ABR cable assembly.

The TR-45L Skinny, unlike my original TR-45L, has no internal Z-Match ATU, nor does it have an internal battery. In fact, there’s no room for either in the Skinny, so it’s not even an option.

I paired the Skinny with my Chelegance MC-750, which is a resonant antenna when deployed correctly, so there was no need for a matching device. I supplied power via one of my 3Ah Bioenno LiFePO4 batteries.

Setup was simple and easy!

POTA with Jonathan (KM4CFT) at the Zebulon Vance Birthplace (K-6856)

4 Comments

On Thursday, December 28, 2023, I had the good fortune of meeting up with Jonathan (KM4CFT) at the Zebulon Vance Historic Birthplace (K-6856) to play a little POTA.

You might recognize Jonathan’s callsign because he has a popular YouTube channel and also produces excellent EFHW antenna kits.

These days, Jonathan lives in Colorado, but he’s originally from western North Carolina. We met once before when he was in town visiting his folks. That previous time was very short, though; this time, we wanted to meetup and fit in a POTA activation together.

We arranged to meet around 2:00 in the afternoon at the Vance Birthplace.

We decided to deploy one of Jonathan’s End-Fed Half-Wave antennas. He cut this particular one for 20 meters.

We set up under the picnic shelter with the antenna essentially in a sloper configuration.

Gear:

Note: All Amazon, CW Morse, ABR, Chelegance, eBay, and Radioddity links are affiliate/partnerhip links that support QRPer.com at no cost to you.

I brought along a couple of radios that Jonathan had yet to operate. He chose to use the Penntek TR-45L (great choice!).

One wrinkle: Jonathan operates with his paddle in “reverse” with the left paddle sending dashes and the right sending dits.

Unfortunately, the TR-45L doesn’t have a software function to flip between “normal” and “reverse” settings. No problem, though: Jonathan simply turned his key (a BaMaKey TP-III) upside down! Problem solved!

The only annoying issue was the 45L speaker–something inside the chassis or speaker assembly was rattling/buzzing with louder signals and with the sidetone. After noticing the speaker vibration at an activation in South Carolina a few months ago, I opened up the TR-45L at the QTH and tried to tighten down anything that could resonate inside the chassis. My fix seemed to work until we powered it up for Jonathan to use. I may have to add some padding around the speaker assembly if I can’t locate the culprit inside the radio–it could be pretty much anything.

Jonathan plugged along and paid no attention to the buzz, nor my fiddling with the radio while he operated. (You’re a good sport, OM!).

Here’s Jonathan’s QSO Map:

After he completed his activation, Jonathan handed over the radio to me.

Since I couldn’t sort out the acoustic buzz/vibration without opening the radio on the picnic table, I opted to swap out the TR-45L with my Discovery TX-500.

I hopped on the air and logged quite a few stations on 20 meters. It was serious fun!

Here’s my QSO Map:

POTA Meetups

Jonathan, it was great hanging with you and, again, I’m so impressed with your CW progress. It seems like only yesterday when you started your CW journey!

When folks are passing through western NC it can be difficult for our schedules to align for a POTA meetup,  but I’m so happy when they do.

Thank you!

Thank you for joining us on this joint activation!

I hope you enjoyed the field report and ctivation video as much as I enjoyed creating them.

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.

Pairing the Elecraft KH1 and my Tufteln No-Transformer (aka, Speaker Wire) Antenna

5 Comments

On Thursday, November 30, 2023 I had a chunk of afternoon open to fit in some Parks On The Air time. My travels took me near one of my favorite local parks: the Zebulon Vance Birthplace Historic Site (K-6856).

As I packed my car that morning, I brought along some of my Mountain Topper transceivers as well. The plan was to first shoot a video comping the new Elecraft KH1 to these venerable SOTA machines, then do a POTA activation with the KH1 and a new-to-me kit antenna.

The Mountain Topper comparison took a bit longer than I had anticipated (surprise, surprise) so my POTA time was actually somewhat limited. If interested, my KH1/Mountain Topper comparison was posted several weeks ago–click here to check it out.

Tufteln No-Transformer EFRW

One goal of my afternoon activation was to finally put my new-to-me Tufteln “No-Transformer” end-fed random wire antenna on the air.

You might recall that I shared a campsite–during the W4 SOTA campout last year–with good friend Joshua (N5FY) of Tufteln fame and fortune. Being the antenna guy he is, Joshua brought along a full antenna building station and set it up on our picnic table. That first afternoon at camp, he gave me a kit to build this random wire antenna. Thanks again, OM!
These “No-Transformer” random wire antennas are designed to be paired with a good ATU–either external or internal. This type of antenna couldn’t be more simple.

Since there’s no transformer (no 9:1, etc.) the ATU does all of the heavy lifting to make a match. While this might not seem like an efficient way of doing things, one benefit of this design is that there’s no feed line: the radiator and counterpoise connect directly to the radio if your radio has a built-in ATU.  I’ve found that there’s some inherent efficiency in this approach.

Just two wires (radiator and counterpoise) connected directly to a BNC with a little strain relief.

The antenna is identical to the speaker wire antenna I built in the field and have used so extensively over the past few years. Joshua’s design is just much lower-profile and more compact.

When I built this particular antenna, I decided to go for a much longer length than any other random wire I’ve made to date. The idea was to have an antenna that might possibly match 80M. Joshua might correct me, but I believe we cut something between 70-80 feet for the radiator.

At Vance, I deployed this antenna into some short evergreens that surround the picnic shelter. It wasn’t an ideal deployment, per se, but adequate for a quickie activation!

I’ve learned that the length I chose for this radiator isn’t ideal for most of my ATUs to hit some bands. I will end up trimming this antenna a bit until I find the right length. I’m tempted to shorten it for matching on 60 meters, then build another 9:1 random wire to hit 80 and possibly 160 meters.

Setting up the KH1 took no time at all. I did discover during this activation that I needed to better secure the KH1 to the table. Wind gusts were tugging on the random wire a bit (as the trees swayed) and it would move the KH1 around on the table. The KH1 weighs less than a pound, so it’s super lightweight! This will be easy to fix next time.

I tuned the EFRW antenna on 30M and got a perfect impedance match.

I started calling CQ POTA and hunters replied!

In fact, I worked ten stations in exactly ten minutes. Two of them were Park-To-Parks–thanks KD8IE and KC3WPW!

I worked two more stations for a total of only twelve logged. I would like to have spent more time on the air, but I had two appointments on my schedule that afternoon.

Thank you!

Thank you for joining me on this short activation!

Had I realized how low I was running on time at the beginning of this activation, I might have made the antenna deployment and my commentary a bit briefer to have more air time. That said, I don’t do POTA for the numbers, I do it because it’s amazing fun and such a positive part of my day. This little activation was no exception! Pure radio fun.

I hope you enjoyed this field report and my activation video as much as I enjoyed creating them.

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.

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

34 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.

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

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.

POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND

2 Comments

I love testing new stuff in the field and on Tuesday, May 2, 2023 I had a great opportunity to test a number of new items.

FT-818ND Upgrades

I mentioned in a previous post that I purchased a new Yaesu FT-818ND from DX Engineering on December 28, 2022. It smacked of an impulse purchase only in that I had not planned to purchase the radio that very day.

Thing is, Yaesu announced they were discontinuing the FT-818 and I always planned to purchase one to replace out one of my two FT-817NDs. I didn’t want to miss the opportunity to buy a new one under warranty, so I bit the bullet on short notice.

Within a few days of purchasing the FT-818ND, I also purchased another 500 kHz CW filter, a WINDCAMP 3000mAh LIPO battery and a WINDCAMP Anderson PowerPole Adapter.

I planned to make the FT-818ND my primary HF radio and use the other FT-817(s) for full duplex satellite work (and HF too, of course, especially since one is now in a TPA-817 pack frame).

I had all of the upgrades in hand by mid-February, but that Yaesu FT-818ND sat in its box under my radio bench until late April. I was so busy evaluating other gear and keeping up with my busy family life,  it had almost slipped my mind. Well, that and I received the incorrect narrow Collins filter from a seller on eBay; instead of sourcing a replacement, I decided to steal an original 500 Hz filter from one of my other radios while waiting on a replacement.

Those narrow Collins filters? They’ve become pure unobtainium over the past couple of months. At one point, eBay was chock full of them. No longer…

It had actually been a very long time since I pulled out a brand new (non-loaner) radio from the box. It’s funny because I remember opening my first FT-817 back in…what…2001? The box and packaging were identical some twenty one years later!

I unboxed then immediately opened the chassis of the FT-818ND to add the Collins filter, attach my Portable Zero side rails (stolen from my FT-817), add the Windcamp battery pack, and add the Windcamp Anderson PP adapter.

JNCRadio CS-818 ATU

Around the same time, Jesse, with Chelegance, also sent me his latest ATU: the CS-818 which is specifically designed to work with the FT-817 and FT-818 series radios. To be clear, Jesse sent the MC-818 at no cost to me to evaluate.

The CS-818 actually works with any radio, but it ships with the command cable for the FT-817/818 for full integration.

The CS-818 can handle up to 30 watts of power, so it’ll pair nicely with any QRP radio. If using it with a QRO radio, you’d have to be very careful not to push more than 30 watts.

NOTE: Due to the frame rate of my camera and the refresh rate of the OLED display, only a portion of the display shows up in my shots.

In truth, ATUs don’t get me terribly excited. I’m quite content with my Elecraft T1 and Emtech ZM-2; these two portable ATUs match anything and everything I use in the field. Continue reading POTA QRP: Testing the new JNCRadio CS-818 ATU with my upgraded Yaesu FT-818ND →

Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation

Welcome to another Postcard Field Report!

I’m still in Dayton after Hamvention weekend, but didn’t want to skip my field report and activation video, so a hope you enjoy the slightly shorter report below:

Zebulon Vance Historic Birthplace (K-6856)

On Tuesday, April 25, 2023, I once again stopped by my weekly POTA spot, the Vance Birthplace.  By mid-May, I will no longer be passing by this excellent little POTA site on a weekly basis, so my activations here will be much less frequent. A shame because I do love this site and its staff!

For this particular activation, I’d planned to test my almost perfectly trimmed QRPguys Tunable EFHW antenna, but I left it at home. Not a problem, actually, because after this activation, I discovered it’s not as resonant as I’d like on the 20, 15, and 10 meter bands, so I may tinker with the toroid windings a bit–perhaps removing one.

Instead, I deployed my MM0OPX EFHW which I thought was actually a great choice considering propagation had been incredibly unstable the previous few days.

Since I also had my Elecraft KX2, I knew I could use its built-in ATU to move to non-resonant bands like 17 and 30 meters.

This activation video is a long one because I had quite a lot of time to play radio and, frankly, it was nice taking things at a casual pace.

After deploying the antenna (twice!) I set up the radio, connected my Begali Traveler, and hopped on the air! Continue reading Postcard Field Report: Pairing the Elecraft KX2 and MM0OPX EFHW to face dubious propagation →
