Elecraft KH1 in Motion: Proper Pedestrian Mobile Activation in an Ohio State Nature Preserve

I arrived back at the QTH late yesterday afternoon after an amazing week of travels.

I’ve got (no kidding) more than 100 emails in the inbox that require attention, so if you’ve written to me recently, my apologies in advance for the late reply. I’m spending the next few days catching up with my family.

I did, however, want to take a moment and share a short field report from a pretty extraordinary activation (for me) that took place on Monday, May 20, 2024.

Hamvention Decompression Day

I learned a few years ago that I need a full day post-Hamvention to wind down and relax before starting my travels back home. Fortunately, my FDIM/Hamvention travel companions Eric (WD8RIF) and Miles (KD8KNC) feel the same way. Nearly a decade ago, we started adding a Monday on to our travels.

Typically, we spend most of Monday at the USAF Museum in Dayton – it’s a brilliant, relaxing way to chill out.

This year, however, we decided to shake things up since I’d just spent a full day at the USAF museum in April with my family during our 2024 Total Solar Eclipse trip.

Eric suggested that we check out the Armstrong Air and Space Museum in Wapakoneta, Ohio, then activate nearby Gross Memorial Woods State Nature Preserve (US-9410). We all agreed that sounded ideal.

In the BX and Commissary Complex on WPAFB

We packed up and left the hotel around 9:00 AM, then made our way to Wright-Patterson Air Force Base. Miles and Eric wanted to pop by the Commissary, BX, and Clothing Sales to pick up a few items (I purchased two more Rite in the Rain notepads, too!).

Armstrong museum entrance

We then drove one hour north to the Armstrong museum where we enjoyed nearly two hours browsing all of the displays and reading about the amazing life and adventures of Neil Armstrong – the first person to set foot on the moon.

After leaving the museum, we popped by a local deli and ate lunch – we were served possibly the largest portions of food I think I’ve ever seen. I could only eat half of my pork sandwich! (Al Woody’s Diner, in case you’re interested.)

Gross Memorial Woods State Nature Preserve (US-9410)

Gross Memorial Woods SNP was a short 15 minute drive from Wapakoneta.

We arrived on-site to find a small gravel parking area and a large, older-growth wooded area.

This is a nature preserve, so there was no shortage of “do nots” on the welcome sign.

The preserve consists of a 0.6 mile loop boardwalk trail with two or so wooden benches. There are no tables and you’re not supposed to step foot off of the trail.

Eric and I, of course, opted for low-impact radio gear.

Eric set up his KX2 field kit and used a small telescoping fiberglass pole to suspend his random wire antenna.

I’d initially planned to use my KX2 and a wire antenna, but I didn’t want to put a wire in a tree and I had no separate pole to suspend my antenna like Eric did.

Instead, I thought this might be a wonderful opportunity to test something new: pedestrian mobile with my Elecraft KH1 as I walked the loop trail.

Four Miles of Radio Goodness

Keep in mind that, while I got a fair amount of walking in during Hamvention, I’d also spent most of the day in the car on Sunday as we activated parks in Ohio and Indiana, so I was eager to stretch my legs.

I, once again, used my Tufteln angle adapter on the KH1 (you can see it as the red adapter on the antenna port in the photos). This adapter makes the operating angle a little more pleasant while pedestrian mobile.

Photo of the Tufteln angle adapter from the previous day’s activation.

The 13’ counterpoise wire simply trailed behind me as I walked. Being a boardwalk, it did have a tendency to very slightly pull the end of the counterpoise wire when it would slip between boards. Hypothetically, the wire could slip between boards and get pinched, but that never really happened. Since the end of the counterpoise was bare wire though, there was nothing to easily catch in the boards.

I’ve been thinking about building in a fail-safe mini banana plug connection/link near the top of my counterpoise that would simply pull away from the radio if the counterpoise were to ever grab something (or I trip on it). Since I hadn’t made this mod yet, I wrapped the counterpoise twice around a finger on my left hand as I held the radio. This provided a bit of strain relief. Again, there was never a problem with the counterpoise grabbing, but I wasn’t going to take my chances!

Also, I should note that I wouldn’t attempt operating the KH1 while, say, hiking up a summit trail. While that sounds like fun, I’m quite prone to trip on rocks and roots which is why I use two hiking poles.

I would limit my activations-in-motion to  roads and paths that are smooth and have no exposed tree roots or steep inclines/declines.

The path at Gross Memorial was smooth and had no trip hazards (trust me, I would have found them!).

I prefer my new Zebra pencil!

As a gift, my wife purchased a Zebra Mini Mechanical Pencil [affiliate link]which is identical to the Zebra Space Pen supplied in the KH1 Edgewood Package (you can see it between my fingers in the image above).

This was the second activation where I used the pencil and I must say that I, personally, prefer it to the pen. The reason why is I find that the pencil requires a little less pressure to write which is perfect for pedestrian mobile logging on the KH1 logging tray.

If you have a KH1 Edgewood Package, I’d recommend giving the Zebra pencil a try: it’s affordable at roughly $6.50 US and a nice option for the KH1.

**Horrible Band Conditions**

Propagation? Yeah, it was in the dumps. Conditions were very unstable and the numbers were not in favor of an easy activation.

Eric and I knew this activation would take some time.

Part of me felt like using the KH1 and its 4’ whip would be fairly futile, but I started out of the gate with a little promise.

As I turned on the KH1 and searched for a free spot on 20 meters, I happened upon Eric (VA2IDX) activating Mont-Saint-Bruno National Park (CA-0508) near Montréal. It only took one or two calls to work him. We were both pretty weak, but I was so pleased to start out this pedestrian mobile activation with a P2P from across our northern border.

Post-Hamvention Activation with Friends

The 2024 Dayton Hamvention is in the books!

This morning, I’m still at our hotel in Dayton, Ohio, but about to pack up and head out. Eric (WD8RIF), Miles (KD8KNC), and I are heading for a day at the Armstrong Aerospace Museum, then, hopefully, a POTA activation on the way back to Athens, Ohio, where I’ll spend the night.

Tuesday morning, I’ll be up early and hit the road for North Carolina. Really looking forward to seeing my wife, daughters, and Hazel.

I thought I’d share a very brief POTA activation I enjoyed yesterday with friends.

Pater State Wildlife Area (US-9492)

Yesterday morning (May 19, 2024), Eric, Miles and I met up with Kyle (AA0Z), Brian (K3ES), Joshua (N5FY), and Charlie (NJ7V) at our hotel.

Eric, Miles, Brian, and I had planned to activate a park in nearby Indiana that afternoon, as Brian and I had never activated in that state. Joshua, Charlie, and Kyle were planning to join us on an activation in southwest Ohio en route. Unfortunately, Joshua was driving back to his home in Georgia, and Kyle was dropping off Charlie at the airport on his way home, so they couldn’t join us in Indiana.

Eric’s first POTA activation with his Elecraft KH1!

We arrived on-site a little after 10:00 AM local. Eric immediately set up his Elecraft KH1 in desktop mode using his new Tufteln KH1 Right-Angle adapter.

Brian set up under a tree with his Elecraft KX2 and a Tufteln random wire antenna.

The amazing Brian (K3ES)

I grabbed my Elecraft KH1 and we coordinated frequencies. Brian took 30 meters, Eric took 40 meters, and I took 17 meters (thinking either Joshua or Eric might move to 20 meters).

This was another instance where having a fully handheld, pedestrian mobile station truly offered a level of activation freedom.

The bands were in rough shape, but I kept my KH1 in hand and walked around the entire site with the CW Message memory sending out my “CQ POTA DE K4SWL.”

Over the course of 13 minutes, I worked five stations. All the while, I was holding the KH1, chatting with my friends, and petting a sweet local dog that instantly made friends with us.

This pup was a hoot!

This activation also gave me an excuse to try out the new Tufteln KH1 Antenna Angle Adapter which makes it a breeze to keep the antenna nearly vertical while holding the KH1 at a more comfortable angle. Thanks, Joshua!

Eventually, I moved to 20 meters and we all started working each other to help with our QSO count and to simply get each other in the logs. I logged two more stations, plus Charlie, Brian, and Joshua to make my 10.

Kyle (AA0Z) and his brilliant Toyota Tacoma POTA machine.

The idea was to hop off the air quickly so that Kyle and Charlie could use Kyle’s KX3 station to activate the park as well.

L to R: Kyle, Joshua and Charlie

Conditions deteriorated further, so we did rely on a few P2Ps with each other to help Charlie and Kyle finish and hit the road.

Charlie calling CQ POTA

Here’s my QSO Map, but keep in mind that several of the pins are incorrect as Charlie, Kyle, Brian, and Joshua were all on-site:

All in all, we had an amazing time and it was a nice, relaxed way to wind down after an incredibly active 2024 Hamvention and FDIM conference.

Joshua working us P2P with his KH1 and the the most compromised–yet completely effective–antenna of all: a dummy load!

I will report more on Hamvention and share a few photos later this week.

For now, I need to wrap up this post and hit the road! There’s an aviation museum and POTA in my future today!

Heartfelt Thank You

I will add this one extra note: I’m simply overwhelmed with the kind comments and conversations I had with so many of you who took the time to catch up with me these past few days. Thank you so much!

Cheers & 72,
Thomas (K4SWL)

A CW Operator’s First Look at the (tr)uSDX by Malahit

by Bob Houf  (K7ZB)  

April 22, 2024 – Gilbert, AZ

I recently bought an assembled (tr)uSDX from Amazon.com [affiliate link] in April, 2024, the mainboard is version 1.2 and the RF board is version 1.0.

Due to antenna limitations – a 17-foot wire antenna with a 6-foot counterpoise hanging from a second-floor condo balcony, matched through a Tokyo Hi-Power antenna coupler for an SWR well below 2:1 – I’ve been operating exclusively on the 20-meter band.

A short coax run into the dining room has given me some great on-air time over the weekend, with good band conditions for 20-meter CW.

The radio powers up when 13VDC is applied and I quickly figured out the menu structure with the minimal documentation available from DL2MAN.

I’ve learned that the filter is best set to 500Hz and it is effective for the conditions, and as the band gets hot with all the various weekend contests, I drop in a little attenuation and soon the radio begins to sound good – actually, for the money, it sounds really good.

QSK set to ON allows my keyer in Iambic B to do a good job and I don’t miss any contacts which are forthcoming across the US from Oregon out to the East coast, on down to the Virgin Islands and then, quite a surprise, my Magnificent 7 Watts is heard for a choice contact with a VK2 down under.

I pound out contest QSO’s all up and down the band, adding in a few SOTA and POTA stations and very few have trouble copying me – I certainly had no problem copying weak signals from them.

I do notice that this is not a $1,500 transceiver, especially in the receiver performance, but for the price the satisfaction derived from effortlessly working CW makes up for any limitations.

During the MST contest, as I write this, stations were piled on top of each other. I found that tightening the filter down to 50Hz wasn’t ideal – 500Hz worked better for my ears. Signals filled the band from 14.030 to nearly 14.050, ranging from very weak to extremely strong. Thankfully, the well-behaved AGC prevented any ear-splitting surprises.

I also tested SSB mode briefly and it works and sounds good, though I’m unlikely to use it much myself.

Overall, this little gem is far from a toy. With its filters, AGC, attenuator, and fine-tuning, it should bring a smile to any CW operator’s face.

Did you know there’s a new MTR-3B in the works–?

A reader reached out to me this morning asking about the Mountain Topper MTR-3B. It reminded me of a teaser LnR Precision posted earlier this month in an MTR-4B update on their website. Here’s what they said:

Update: 4/1/23: We do not have MTR4 V2.3 available for purchase now but will be releasing more for purchase on May 1, 2024.

Apologies on the delay but we needed more time to get parts that are in short supply and fabricate. This will be the only and last offering of the MTR4b V2.3 radios as we are shifting focus on a redesigned and re-engineered version of the popular MTR3B!

It is our hope to have these out in Fall of 2024 if possible, but no guarantees.

I’m very excited about this news! I own two MTR-3Bs and absolutely love this model. When I checked in with LnR a couple of years ago, they said they had no plans to produce the MTR-3B again. They must have noticed the strong customer demand.

I assume the new model might incorporate some of the upgrades found on the MTR-4B, like an SWR and Power Output meter and a more accessible sidetone control. We’ll have to wait and see!

LnR is a small “mom-and-pop” company, so we’ll need to be patient as they introduce the new MTR-3B. I’m sure they’ll struggle to keep up with demand. I, for one, am eager to see this super-compact transceiver back on the market.

Alan demonstrates how to quickly tune the TR-45L’s Z-Match Tuner

Our friend Alan (W2AEW) just published this excellent short video demonstrating how to quickly tune the Penntek TR-45L’s Z-Match ATU. Of course, this same technique can be applied to the Emtech ZM-2 or any other manual Z-Match tuner:

An excellent tutorial, Alan! Thank you!

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

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!

Zebulon B. Vance Birthplace (US-6856)

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!

On The Air

I started calling CQ POTA on the 40 meter band, hoping it would be a little productive while we were still in the latter part of the morning. Continue reading My first POTA Activation with the Index Labs QRP Plus Field Transceiver

John’s KH1 Redeems an Otherwise “Frustrating” Start to a Cross-Country POTA Rove

Many thanks to John (NS6X) who shares the following field report:


Frustrating rove from California QTH to OzarkCon in Branson, MO.

by John (NS6X)

I had great plans for a radio-centric, POTA activation road trip from my home in Camarillo, CA (outside Los Angeles) to my first visit to OzarkCon in Branson, MO. The Four State QRP Club hosts the two-day conference. I recently became a kitter (I put together one of the kits) for the club, assembling the parts and shipping the Cricket20 (see kits a 4SQRP.com).

I had the parks planned out along I-40 where I would stop, overnight stops for my little trailer, and my traveling companion Sachiko (Agnes), my Tortie cat.

Long story, but my wife of 48 years died three years ago from ovarian cancer, so I now enjoy traveling alone. I am calling my trip story, “Traveling with Agnes,” a shout out to John Steinbeck and Traveling With Charley. I seldom plan ahead, so to have night stops, parks planned, and such was something for me.

I packed my Elecraft KX2, KH1, FT-891, Penntek TR-35L, and my 22-year-old KX1. I have multiple Bioenno batteries for power, that I packed in an official QRPer.com/HRWB bag and placed next to the door.

I should have stepped out of the door and put it in my truck or trailer, as I left the batteries at home. I did have a Bioenno solar “generator”, but it doesn’t have power pole output connectors, and I haven’t made power pole-adapted cables for it. And of course, I left my power pole crimpers and connectors at home, too. I didn’t discover this until I stopped at my first POTA park, the US-1058, Homolovi Ruins State Park in Arizona, just outside of Winslow.

My KX2 had a partially charged battery, so after futzing about with the power sources, I set up my KX2 and AX1 antenna. I was able to make 7 QSOs in a little less than an hour, even after spotting myself, but did not have the time to stay longer to complete the activation. My campsite was at a KOA in Albuquerque; it was raining/snowing/hailing, and my next stop at the Petrified Forest was out, too. I was discouraged, so packed up and took off.

I had watched Thomas’, K4SWL’s videos and read about the KH1 being used as a radio for an activation, but after my limited number of contacts in Arizona, I wasn’t too positive about it. However, coming from a suburban lot in a housing tract, the lack of QRN/M noise in the Arizona desert was amazing. I didn’t think that I had turned on the radio, seriously.

So, driving through New Mexico, and part of Texas, into Oklahoma for the evening, stopping at a Harvest Host location for the night, I decided I would listen to the bands, using the KH1. I heard a few signals. My stop was only a few miles from the Washita County Wildlife Management Area, US-8661, so I decided to take the KH1 and mosey over to the POTA site.

I told myself why not, spotted myself on 20 meters at 14.058.2, called CQ and was I surprised. LOUD signals came back. Many stations were calling me. I completed my activation with 12 QSOs in 16 minutes, using the KH1, putting out 4.6 watts. The SWR was about 1.1:1. I was impressed with the stations from Wisconsin, Pennsylvania, Florida, Texas, Missouri, and North Carolina that called me. Did I say they were LOUD? And no noise.

I just finished the activation – forgot to take photos. I was a photojournalism major (although my career was as a firefighter and paramedic). How could I keep forgetting to take photos?

My takeaway and lesson learned was to pack ahead of time, with a checklist (I am never that organized), and that the KH1 is a real radio, able to do things like be used for a POTA activation.

It didn’t hurt that I had a zero noise level, and that there were QRO stations calling me, as well as the spotting system that makes POTA and other similar activities workable, and fun.

After becoming first licensed in 1966 at 11 years old, I am once again excited about ham radio. The social aspect of ham radio is a real positive. The fun of POTA and SOTA is invigorating my radio life. I am back contesting, and putting up a better antenna at my house: the CC&Rs are no longer valid as they haven’t been enforced for more than 35 years, no HOA, and the city issued a permit to me.

I will be back at another Oklahoma park in the morning. I am writing this in the early evening after getting back to my trailer. My KH1 battery is charged, ready to go, if anyone else is ready at 8 AM.

Off to Joplin, MO tomorrow, then Branson, MO for the conference on Thursday, beginning Friday morning. The conference is over Sunday. I did make a reservation for Sunday night in Branson to hang over and watch the eclipse as the sun passes over Branson on Monday.

72’s, NS6X, John Kitchens
