KH1 – WB3GCK QRP Amateur Radio

Outer Banks 2026

My (far) better half and I traveled to the Outer Banks of North Carolina last week for our annual family vacation. As we have done for the better part of 30 years, we rented a house on Currituck Sound and spent the week with our two daughters and their families. Although ham radio didn’t figure prominently on this vacation, I got on the air and made a few QSOs each day.

After the long drive from Pennsylvania to North Carolina, we unloaded three vehicles and got everything situated for the week ahead. I was assigned the task of grilling hotdogs and burgers for dinner, and getting everyone fed was the top priority. After that, I finally had some time to unpack some of my radio gear. We rented the same house we were in last year, so I knew exactly how I was going to set up.

I went with the same antenna I used last year: a 35-ft end-fed wire sloping down from a third-floor deck to a fence in the pool area. To feed the wire, I used my weather-resistant 9:1 unun and ran 25 feet of RG-316 coax into a screened-in section of the deck. While it’s not the greatest antenna in the world, it works reasonably well, sets up in minutes; and is nearly invisible. Given the development the rental house is in, the stealthiness is a big plus.

I didn’t get on the air until the next day. Again, my rig was identical to last year. I used my KX3 with a common-mode choke on the antenna input. I kept everything on a plastic tray, so I could move the station in and out of the screened-in porch.

The monthly SKCC Weekend Sprintathon was on, so I caught a bit of that. This month’s theme was homebrew keys, so I had packed an old straight key I built from an assortment of junk box parts.

When I fired up the KX3, I encountered some local noise, but it didn’t seem as bad as I remembered from last year. I did a quick check and noted that the KX3 loaded up the antenna on every band from 80M through 10M. With an A Index of 27, the band conditions weren’t all that great. Regardless, I worked some SKCC stations and the occasional POTA activator.

It was very hot and humid, so I operated in three short shifts. Towards midday, I started to lose my shade. When that happened, I called it quits. I had 11 WES contacts, including one bonus contact with the club station KS1KCC. I also hunted four POTA activators. After that, I brought the rig inside and went out to spend the afternoon in the pool.

For the rest of the week, I operated on and off from the screened-in porch with the KX3. I limited my operating time to the morning hours while I had shade. I didn’t do any POTA activations this year. Mostly, I tuned around the bands, working whatever stations I could hear. The rest of the day was devoted to typical beach vacation activities.

One morning, I took the KH1 out to the dock for some POTA hunting. The dock is at the end of a 100-yard wooden walkway out on Currituck Sound. I parked myself on a bench and ran the counterpoise wire back down the walkway. I don’t know if being surrounded by water was the reason, but some of the activators were really booming in. I was able to get them on the first call.

Mid-week, a UFI (unidentified flying insect) stung me on the finger while I was in the pool. In the aftermath of the vicious and unprovoked—and perhaps exaggerated—attack, my finger was a little swollen. Thankfully, it didn’t impede my ability to send CW.

In what seemed like the blink of an eye, our week was over. On our last day, I made a few more contacts from the house before taking down the antenna and packing up the radio gear. I ended the week with about 47 contacts, mostly with POTA activators. Among those contacts were eight with KG1A at US-6305 in Florida. I worked him at least once each day I was on the air. Hunting with QRP, a funky antenna, and lots of residential noise is more challenging than activating, but it was still fun.

I had a great time spending the week with my daughters, sons-in-law, grandkids, and the grand-dog. Of course, getting in a little ham radio time with some beautiful scenery wasn’t bad, either.

Stormy Monday Activation

Angry-looking clouds. Unsettled geomagnetic conditions. That sounds like a good time to go activate a park with a compromised antenna. So that’s what I did. When you get the opportunity to go play radio in a park, you just have to go for it.

Early on a Monday morning, I made a trip up to Evansburg State Park (US-1351, KFF-1351). We had some storms overnight, and there were some lingering dark clouds around. So, I hunkered down under a picnic pavilion. I didn’t have much time, so I went with the Elecraft KH1 and its internal whip. Along with the whip, I used a Tufteln 90-degree adapter. For keying, I used my trusty CWMouse paddles on my clipboard.

I installed the AXE1 extender coil for 40M and got started. The noise floor was very low, but I had to endure the occasional loud static crashes from storms in the area. Despite the unsettled geomagnetic field, the first five QSOs came quickly. After working a couple more, I gave 30M a try and logged three more.

With 10 contacts in the log, I removed the AXE1 and moved up to 20M. There was a bit more activity up there, and I made nine more contacts in short order. I shut down after an hour on the air with 19 contacts. That included four park-to-park contacts.

There are far better antennas than the KH1’s 45-inch whip, but probably none faster to deploy. Not to mention the huge fun factor in making contacts with such a diminutive antenna.

A Dog and and a Bumblebee

Once again, I was out in central Pennsylvania for a week. My daughter’s family traveled out of state for my grandson’s hockey tournament. While they were gone, I looked after my grand-dog, Belle, and ‌took care of the house. I spent much of my time walking Belle and taking her on trips to a local park, but I still carved out a little time for ham radio.

Since my grand-dog, Belle, has some separation anxiety when her entire “pack” has to leave her behind, I try not to leave her alone for long. So, instead of activating some of the local parks, I set up an antenna in the backyard for some ‌casual operating.

Using the 35-foot wire I tried out recently, I threw together a wacky but serviceable antenna. From the chair I was operating from, I tossed the wire up over my grandson’s basketball net and ran it over to a 20-foot pole.

I handheld my KH1 and used my K6ARK pressure paddles for keying. Admittedly, I was a little out of practice using those touch paddles, so it took a couple of contacts to get used to them. My apologies to the stations that had to endure my early attempts using them.

As I had hoped, the KH1 found a decent match on each of its five bands. That was the good news. The bad news is that my daughter’s yard is in a low spot and tends to be a little noisy at times. Despite those challenges, I easily worked three POTA activators on 20M during the first of several backyard sessions during the week.

Most days, I took the KH1 out in the backyard for a little airtime in the morning and again in the afternoon. My grand-dog accompanied me, but she preferred to spend her time sunning herself and rolling in the grass. I mostly hunted POTA stations and worked some Alabama QSO Party stations. I also heard the occasional SKCC member, but I wasn’t set up for using a straight key. Most of these sessions were short and ended when Belle decided I needed to pay more attention to her.

Flight of the Bumblebees (FOBB)

As the saying goes, it was déjà vu all over again. I was also out at my daughter’s house for last year’s ill-fated Flight of the Bumblebees contest. After blowing the finals in my (then) brand new KH1, I was hoping for redemption.

For the FOBB, I used my trusty clipboard and CWMouse paddles. This made for easier logging during the contest. I also eliminated the basketball net and sloped the antenna wire up directly to the 20-foot pole.

My setup during the Flight of the Bumblebee (FOBB) contest

Belle and I headed out to the backyard a few minutes after the contest started, and Bumblebee #37 took flight. I started out on 40M and quickly logged my first contact. The local noise was present, but stations were still getting through. Based on the signal reports I received, I was getting out better than I could hear. After an hour, Belle decided it was time to go in. So, with 11 contacts in the log, I went back inside and took a break.

I eventually headed back out for about 30 minutes towards the end of the contest. The conditions seemed better this time around, and I picked up seven more contacts. When I ran out of FOBB stations to work, I called it quits with 18 contacts in the log. Seventeen of those were bumblebees. That was a far better finish than the solitary contact I made last year—and I didn’t blow any finals this time.

Given my surroundings and local noise, I think the 35-foot wire antenna did reasonably well for me this week. My particular configuration was no DX killer; my contacts were mostly in nearby states. My most distant contacts were on 20M during FOBB: Mississippi to the south and Missouri to the west.

Although there was nothing particularly exciting about my backyard-portable operation, I still had a fun week spending some quality time with my grand-dog and getting on the radio now and then.

Trying a 29-Foot Wire with the KH1

When I tested a 35-foot non-resonant wire with my KH1 last week, I was pleased with the results. Continuing with that theme, I thought I’d try a 29-foot wire, another popular non-resonant length.

I drove back to Valley Forge National Historical Park (US-0761, KFF-0761) and re-created the setup I used last time. To support the wire, I again used my homebrew drive-on mount to support a partially extended 31-foot Jackite pole. I’m guessing the pole was up about 27 feet, give or take. I set up my camp chair nearby and ran the wire over to the KH1. Starting off, I used a 17-foot counterpoise wire.

First, I checked to see what kind of match the KH1 would find on its five bands. The SWR was very low on all bands except for 20M, where the best the KH1 would do was around 2.4:1.

I started my activation on 40M, and the wire seemed to get out pretty well. Although the band was noisy with static crashes, I made my first ten contacts in about 11 minutes. I eventually moved up to 30M, but I only had one hunter there.

At that point, I took a break to experiment with counterpoise wires. I tried both 29-foot and 13-foot counterpoise wires, but neither of them improved the match on 20M. I also tried repositioning the counterpoise with no luck.

I left the 13-foot counterpoise wire attached and went back to 40M. I made an additional handful of contacts on 40M before trying 17M. On 17M, I picked up three more before calling it quits.

Admittedly, I had high hopes for the 29-foot wire. I’ve used that length a bunch of times, although usually with a 9:1 unun and rigs with more robust tuners. In any event, it worked well on bands other than 20M. I managed 26 contacts in a little more than an hour.

On the drive home, I thought about some ways to improve the match on 20M. I’m not sure any of them are really worth the effort, though. For now, I’ll just stick with 35-ft when I use a random wire with the KH1.

Trying a 35-foot Wire with the KH1

I headed back to Valley Forge National Historical Park (US-0761, KFF-0761) to try out an antenna configuration I didn’t get to during my last visit. I was eager to see how well my Elecraft KH1’s internal ATU would match it.

The antenna in question is just a 35-foot wire with a 17-foot counterpoise. There’s nothing novel about this configuration, as it’s a popular choice for the Elecraft KH1. Since I bought the KH1 last summer, I had never tried directly feeding a random wire. Since I already had the 35-foot wire I used in North Carolina last year, I gave it a go this morning.

To support the 35-foot wire, I used a 31-foot Jackite pole on my homebrew drive-on mount. I sloped the wire down to my camp chair. I laid out the counterpoise wire in the grass and used a binding post to a BNC adapter to connect both wires to the KH1. To hold the KH1, I used a kneeboard from Tufteln strapped to my leg. I used my CWMouse paddles for sending.

Before starting my activation, I tried the KH1 on each of its five bands. The KH1 found a 1:1 match on both 40M and 30M. The 20M band gave the highest SWR at 1.6:1; however, the KH1 was putting out a full five watts on that band. On both 17M and 15M, the SWR was a respectable 1.3:1.

Satisfied that the KH1 was happy with this antenna configuration, I got underway on 40M. The wire seemed to get ust fine, but it’s hard to judge an antenna’s performance on the air. There are just too many variables in play. Anyway, I made contacts all up and down the East Coast and out to the mid-west. I ended up making contacts on 40M, 30M, and 20M. It was a bit too early in the morning for 17M and 15M.

After an hour and 10 minutes, I wrapped up with 25 contacts in my log with nine park-to-park contacts. Not too bad for early on a Monday morning, I suppose.

Overall, I was very happy with the 35-foot wire with the KH1. I think it might be a permanent addition to my backpack. It certainly doesn’t take up much room. I’ll probably be using it for the upcoming Flight of the Bumblebees contest.

It’s Been a Minute or Two

Except for Field Day, I’ve been mostly off the air for the past few weeks. To remedy that, I took advantage of a rare day with outstanding weather for a quick, early-morning activation at Valley Forge National Historical Park (US-0761, KFF-0761).

Since I have to be careful with sun exposure these days, I drove straight to an area I knew would have shade all morning. My original plan was to experiment with a wire antenna with my Elecraft KH1, but for reasons I won’t bore you with, that didn’t happen. Instead, I used a whip antenna on my truck and ran coax over to my camp chair and table. My handy-dandy propagation app showed unsettled geomagnetic conditions, so I went with my longer 17-foot whip and homebrew loading coil.

Despite the poor band conditions predicted for 40M, there was no shortage of early risers hunting parks. Although there was a lot of static from impending storms, it only took five or six minutes to make my first ten contacts. After logging 20 contacts on 40M, I changed bands. I made a half-dozen contacts each on 30M and 20M.

I finished up with 32 contacts after an hour and 10 minutes on the air. Eight of those were park-to-park, including one with my friend Ken N3CU, and one on each of the three bands with Tom KG1A in Florida.

I packed up and headed home to cut my grass before the rain moves in tomorrow. Except for a minute or two of sheer panic when I temporarily misplaced the keys to my truck, it was a good morning and fun to get back out in a park.

Persistance is Futile (Sometimes)

Yesterday was the perfect day to be out operating in a park, so I headed over to Valley Forge National Historical Park (US-0761, KFF-0761). I wanted to keep things simple, so I used my Elecraft KH1 and its whip antenna. While this setup has worked surprisingly well for me in the past, yesterday was not one of those times.

When I arrived at the park, I headed to a picnic table in the shade of some large trees. (Given my history with skin cancer, the sun is not my friend these days.) This was a spot I have used before with the KH1, so I was hoping for similar success.

Operating from Valley Forge National Historical Park (US-0761, KFF-0761)

I started out on 40M, using the AXE1 extender coil and a 33-foot counterpoise wire. I also used a Tufteln right-angle adapter with the whip. After quickly logging two contacts, things slowed way down. I spent 20 minutes of fruitless CQing, wondering if I should move on to another setup. Instead of bailing on my KH1 setup, I stubbornly pressed on.

Well, after 30 minutes more of trying various bands on the KH1, I had a paltry four QSOs in the log. It felt like I was beating my head against a wall, so I packed up the KH1 and headed back to my truck. I used my 12-foot base-loaded whip and TR-35 from the truck. I allotted myself 45 more minutes. If I couldn’t reach 10 contacts by then, I would just slink home wallowing in disappointment.

Fortunately, my trusty TR-35 and 12-foot whip saved the day. After 30 minutes, I logged another nine contacts on 40M and 20M. It was getting close to lunchtime and my short attention span was kicking in, so I packed up and headed home.

Yesterday just wasn’t a good day for a 45-inch antenna. Looking back, I should have switched setups sooner and saved myself some frustration. In the words of Don Schlitz, the famous songwriter who passed away recently: “You got to know when to hold ’em, know when to fold ’em.”

Visitors, Geese, and a Busted Activation

This was supposed to be a post about how I made a bazillion POTA/WWFF contacts in an hour. Yeah, well, that didn’t happen. However, I had some interesting visitors stop during my (attempted) activation.

I made a trip over to French Creek State Park (US-1355, KFF-1355) for a short activation and a little antenna experimentation. To make sure I wouldn’t be in anyone’s way, I set up at a picnic table well away from the parking lot.

My antenna today was a vertical wire just under 18 feet fed through a homebrew 9:1 unun with a counterpoise wire just under 9 feet. I ran 20 feet of RG-316 coax over to my Elecraft KH1 on the picnic table. I had used this antenna configuration with my Penntek TR-35 and T1 ATU a few times in the past. While it worked well with that rig, I wanted to see how it would work with the KH1’s ATU.

My first visitors showed up just as I was getting started. It was about six Canada geese who wandered over about 20 feet from my antenna. One of them had a bad attitude and hissed at me when I went over to check the antenna. I calmly told him to buzz off; I was here first. They wisely moved on, de-escalating the situation. I’m pleased to report that no humans or geese were harmed during this brief but intense standoff.

Radio-wise, I wasn’t having much luck. QSOs were few and far between. On paper, the band conditions didn’t look too bad, so I’m not sure what my issue was.

My third contact was an ear-shattering call from my friend N3CU. Ken was also in the park somewhere, so that accounted for his loud signal. I told him where I was, and he came over to visit. I last ran into Ken in French Creek back in January, so it was great catching up with him. Eventually, Ken headed off to continue his activation.

After I got back on the air, I heard a noise in the woods behind me. It was a hiker coming off ‌a trail. He was curious about my antenna, so I gave him my Amateur Radio and Parks on the Air “elevator speech.” After a brief chat, he headed off toward the lake.

After I had six 20M contacts in my log, I moved down to 30M. Just then, another fellow came up to see what I was doing. I was wearing my Navy ball cap, so that prompted five or ten minutes’ worth of “sea stories.”

While we were swapping tall tales, I had the KH1 calling CQ with one of my earbuds in my ear. I heard N3CU calling, so I told my visitor I needed to answer a call. He wished me good luck and headed off towards the parking lot. I needed to get back home, so I shut down and packed up after finishing up with Ken.

So, after an hour and a half, I only had seven contacts in my log. This was my first busted activation in quite some time, but I don’t consider it a failure. I was out in a beautiful park with excellent weather, and I got to catch up with a friend and chat with some other random visitors.

I’m sure I’ll have better luck on the radio next time.

All Aboard the Struggle Bus

I carved some time out of the chaos that is my life lately for some much-needed “radio therapy”. I drove over to Ridley Creek State Park (US-1414, KFF-1414) yesterday morning to take advantage of some great spring-like weather. What I envisioned as an easy in and out POTA/WWFF activation turned out to be one of the more challenging activations I’ve done in a while.

I set up at a picnic table under a large pavilion. Since it was a weekday, I had the pavilion to myself—but not for long. More on that in a bit. To keep things simple, I used my Elecraft KH1 with the whip antenna on a Tufteln right-angle adapter. I ran my counterpoise wire out into the grass. This setup hasn’t failed me yet, so I was feeling confident. For keying, I used my trusty CWMouse paddles.

My setup at Ridley Creek State Park (US-1414, KFF-1414)

It was really slowgoing today. Although I was making some contacts, spots on the Reverse Beacon Network (RBN) were few and far between. That’s not a good sign. Was it band conditions or my location? I don’t know, but I pressed on with dogged determination.

Not long after I got started, a park maintenance worker started mowing the grass in the picnic area. The bands weren’t all that great, and now I had to contend with some loud audio interference. They eventually finished up and moved to another area away from where I was sitting.

After 30 minutes, the 20M band had only produced seven contacts. One of those was 2,400 miles away in California, so my signal was getting out somewhere. Searching and pouncing produced two park-to-park contacts.

Before I knew it, I was sharing the pavilion with a group of about 40 exuberant kids. Apparently, they were on a school trip and taking a break from hiking for lunch. It was nice to see them enjoying the outdoors, but it also meant more audio interference for me. Eventually, some teachers rounded up the kids, and they all headed back down the trail. Once again the surrounding area was quiet, but I still wasn’t making any contacts.

I was stuck at nine contacts for what seemed like an eternity. I checked 17M and 15M a couple of times to no avail. The 20M band was the only one producing any contacts for me, and that wasn’t all that great.

After about an hour and a half, my stubborn persistence was giving way to frustration and resignation. I was about 15 seconds from shutting down and packing up when the elusive tenth contact came in. That contact came in the form of a very loud call from KB5HPM in Mississippi that had me reaching for the KH1’s volume knob. After logging that last contact, I packed up and headed home.

I ended my 40th activation at this park with the bare minimum 10 contacts, but I was okay with that. I’m not sure if this was the hardest I’ve had to work for 10 contacts, but it’s certainly right up there.

A Simple Portable Vertical for 20M-15M

This is one of those antenna projects that started with: “I wonder if…” Designed with my Elecraft KH1 in mind, it covers the 20M, 17M, and 15M with the use of an tuner—similar to how the KH1’s whip antenna operates. It wasn’t something I had a burning need for, but it turned out to be pretty effective.

Concept

For many of my recent activations, I’ve been using my Elecraft KH1 with my base-loaded 12-foot whip. While I built the loading coil for 40M through 17M, I found that the KH1’s internal tuner easily matched the 12-foot whip on 17M and 15M, with the coil bypassed. A 12-foot radiator is resonant somewhere around 19.5 MHz, so it falls in between the 17M and 15M bands. Even though the 12-foot whip is a compromise, I was regularly making DX contacts on those two bands running five watts or less.

That got me thinking about building a more portable antenna for 20M through 15M using a 12-foot radiator. What I came up with was a simple 12-foot wire antenna that uses a loading coil for 20M and just the 12-foot wire for 17M and 15M.

When I thought about it, what I was building was conceptually similar to the Elecraft AX1 antenna and the KH1’s whip antenna. These antennas are close to resonance on 20M and resonant somewhere in between 17M and 15M. My antenna would operate the same way, except it would be almost 8 feet longer. I’ve always had good luck with the AX1 and the KH1’s whip antenna, so I figured my proposed antenna should work even better.

Along with the electrical properties, I wanted to make the antenna small and lightweight, using a #26 AWG radiator along with two 13-foot counterpoise wires. Also, I wanted to use—as much as possible—parts I already had in my junk box.

Parts List

I selected most of the parts based on availability in my junk box. They might not be the optimal choices, but here’s what I used:

T106-2 iron powder toroid
#22 AWG enameled wire (approx. 35 inches)
SPST slide switch. I actually adapted a DPDT slide switch, since I already had a bag of them.
#26 AWG wire (12 ft for radiator)
#26 AWG wire (2x13ft for counterpoise wires)
2mm banana plugs & jacks (2 sets for connecting the counterpoise wires)
(2) ring terminals
BNC female jack
(2) 4-40 x ¾-inch bolts plus some washers and nuts for the antenna and counterpoise connections. I used a couple of knurled nuts I had on hand.
Plastic box. I had one that measures about 2.5 x 1.75 x 1 inches.

Construction:

When I first thought about building this thing, I originally envisioned a more field-friendly form factor with built-in winders for the antenna and counterpoise wires. Since I constrained myself to using parts I already had (and I don’t own a 3-D printer), I used a plastic box I bought years ago but never used.

The construction was pretty simple; it’s just a toroid, a switch, and some connectors in a box. They say a picture is worth a thousand words, so have a look at the accompanying pictures to see how I built it.

Inside the matchbox for my 20M-15M 12-ft vertical — Inside the matchbox

I used some online calculators to determine the loading inductance needed for 20M. Assuming I would need to tweak the number of turns, I started with one turn more than I had estimated. It’s easier to remove turns than to add turns—don’t ask me how I know this.

I used some foam mounting tape to hold the toroid in place. For good measure, I also wedged ‌in a piece of Styrofoam between the toroid and the lid. That adds some assurance that the toroid won’t come loose in the field. The trickiest part was cutting a square opening for the slide switch. That took some careful work with a nibbler tool and a file to get it done without destroying the box.

You could use a tree branch to support this antenna, but I like to keep my field setups self-contained. I found a cheap telescopic pole on eBay that measures about 12’ 3” fully extended, so I went with that.

Typical picnic table setup with the 12-ft vertical and Elecraft KH1

I envisioned using this antenna primarily for “picnic table-portable” operation, running a short length of coax to the radio. Using a piece of PVC pipe and a PVC elbow fitting, I built a simple mount for clamping to a table. As luck would have it, the base of the pole fits perfectly inside a ¾-inch PVC pipe. I just use a C-clamp to fasten the elbow to the table and slide the pole into the pipe. When I built the mount, I inserted a small screw partway up the pipe to give the pole a few more inches of height. A six-foot length of RG316 is more than enough to reach the radio at the other end of the table.

Testing in the Field

I don’t have a good place for antenna experimentation where I live, so it took several trips to the field to tweak the inductor. On each trip, I took readings with an antenna analyzer, made any necessary adjustments to the loading coil when I got back home, and repeated the process on the next outing. That was a tedious process, which was spread out over a few months because of winter weather.

Once I set the antenna up in the field, I found I needed far fewer turns than I originally estimated. Initially, the antenna was resonating well below the 20M band, so I removed a turn at a time. Since I was going to need to use an ATU for 17M and 15M anyway, I didn’t get too fussy about getting it exactly resonant on 20M. However, I eventually got it resonating in the 20M band, with an SWR under 1.5:1 across the band.

The good news was that, even though I hadn’t finished tweaking the coil, the KH1 easily found a match. I had five successful activations during those testing sessions, typically running 3.5 to 4 watts. I consistently worked stations in Europe on all three bands, along with some U.S. stations on the west coast. On one outing, I worked W6LEN in California on all three bands from a park here in southeastern Pennsylvania. During my final testing session with the antenna, I had a 20-minute two-way QRP QSO with DL4ISX on 15M (CW). I declared the project completed at that point.

Below is a schematic showing the final configuration:

Wrap-up

So, there you have it. No revolutionary technical breakthrough here, just a fun little project that has been even more fun to use. I envision many more picnic-table-portable activations with it.
