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.

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!).

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.

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.
