The (far) better half and I made a trip out to central Pennsylvania to attend some activities our grand-kids are taking part in. I had some time on Saturday morning for a quick activation, so I drove a few miles down the road to nearby PA State Game Lands (US-8941, KFF-5862).
We made the trip in the (far) better half’s little Chevy Traiblazer, so like a previous trip, I went with a simple setup. Along with my Penntek TR-35 (5W, CW), I used my Elecraft AX1 on a clip-on window mount. The diminutive AX1 has always gotten the job done in the past, so I hoped for similar results today.
My AX1 on the window mount
Today, I had a couple of things working against me: doing an early morning activation (0900 local time) on 20M coupled with some unsettled geomagnetic conditions. Not to mention running 5 watts into a 45-inch loaded whip. Still, I enjoy a challenge. Or maybe I’m just a glutton for punishment.
With the AX1, it only took a few minutes to get set up and get on the air. After spotting myself, it took nine minutes of CQing to make my first contact. Then, 19 minutes after that, I made contact number two. Yikes! It was looking like I was headed for my first busted activation with the AX1. I also began wishing I had brought my Gabil GRA-7350TC and mag mount, so I could have made some contacts down on 40M. Undeterred, I pressed on.
The crowded operating position in my (far) better half’s car
Not too long after that, things picked up a bit, and I started getting some more callers. Either the band conditions were improving or the hunters were waking up and getting out of bed. One of those callers was OH1MM. I had a weak copy on him, so I can only imagine what my QRP signal sounded like in Finland.
An hour after arriving onsite, I had 14 contacts, including one park-to-park and one DX contact. I was happy with that, so I packed up and headed back to my daughter’s house for a late breakfast.
So, despite getting off to a slow start, my little AX1’s undefeated streak remains intact.
Well, the 2024 edition of our annual Outer Banks family vacation has come and gone. My (far) better half and I, along with our two daughters and their families, converged on a rental house in Duck, North Carolina. Of course, ham radio (for me, at least) was a part of that vacation.
Our view of Currituck Sound
After an early morning start, our long drive from Pennsylvania to North Carolina on Sunday was relatively uneventful, and the traffic on the Outer Banks wasn’t too bad. We all arrived safely, albeit a little road weary.
This year, we rented the same house overlooking Currituck Sound we were in last year. Being familiar with the layout of the rental house, I had an entire year to think about my antenna situation. The vertical I used the last time was somewhat noisy on 40M, and my 31-foot Jackite pole really took a beating in the wind. This year, I tried something a little different.
My antenna layout. The wire wasn’t visible in the picture, so I enhanced it. The coax dropped straight down from the unun and through the ground floor window.
I wanted to avoid using a telescopic pole, so I strapped my homebrew weather-resistant 9:1 unun to the railing on the third floor deck. From there, I configured a 29.5-foot wire as a sloper, and tied it off to a fence post. I dropped 35 feet of RG-8x coax off the deck and fed it through a ground floor window, where I set up my KX3. I also used a 1:1 choke at the radio end. I’ve used this antenna configuration in the past with good results, so I was confident it would work here.

Giving it a quick test, I found the noise on 40M was only S1-S2. That was an improvement from last year. There were no noise issues on 30M and up. I tuned around on 40M and made two quick Straight Key Century Club (SKCC) Weekend Sprintathon (WES) contacts. There were some storms in the area, so I declared victory, disconnected the antenna, and cracked open a cold adult beverage.
My portable station next to a window in the game room on the ground floor. I re-used the foam pool noodle from last year to seal the window opening where my coax enters.
Although most of my time was devoted to other vacation activities, I squeezed in some radio time and made a few contacts from the house each day. I mostly hunted POTA activators and SKCC members.
When I’m down here, I always like to check into the Outer Banks Area Wide Net on Thursday evening at 8pm (local time). They are always a friendly and welcoming group. The Outer Banks Repeater Association maintains a linked system of repeaters covering the entire area, so I easily hit a repeater across the sound with an HT while sitting out on the deck.
Jockey’s Ridge State Park (US-2737, KFF-2737)
I planned to do one or two POTA/WWFF activations during the week. On Tuesday, I took a 30-minute drive down to Jockey’s Ridge State Park. Since this is a family vacation, I went out early and kept it short, so I could get back and spend time with the grand-kids.
It had been 25 years or more since my last visit to the park. So, when I rolled into the main parking lot, it was nothing at all like I remembered. Still, I found a shaded parking spot and set up my 12-foot whip and homebrew loading coil on the back of the truck. I used my trusty Penntek TR-35 (5 watts, CW) up front in the truck.
Activating Jockey’s Ridge State Park (US-2737, KFF-2737)
I was glad to see that the bands had started to bounce back after the severe geomagnetic storms of the previous couple of days. In less than an hour of air time, I logged 23 contacts with four park-to-park contacts. I didn’t work any DX, although I heard a French station calling. They were just too far down in the noise to copy their callsign. On the plus side, however, I worked a station in Nevada on 20M.
This is the sandy trail in Jockey’s Ridge State Park that leads back to the dunes.
Jockey’s Ridge is known for having the tallest living sand dune system on the East Coast. It’s also a very popular spot for hang gliding. I didn’t have time to make the trek out to the dunes this time, but I have been there before. I didn’t take any pictures that do the park justice, but the Outer Banks Visitor’s Guide website has some great ones.
Nags Head Woods Preserve (US-3862, KFF-3862)
I got in one more POTA/WWFF activation during the week. This time I drove down to Nags Head Woods Preserve, an interesting park that was not without some (radio) challenges.
I rolled into the parking lot and grabbed a spot near the entrance and away from the other cars. I was in a hurry to get set up. My friend, N3FLL, was activating a park back home in Pennsylvania and I wanted to snag a park-to-park QSO with him.
I used my usual setup: Penntek TR-35 (5W CW) and 12-foot loaded whip. I powered up and found lots of electrical noise on 40M. Noise notwithstanding, I quickly found Frank, and after a few attempts to break the pile up, I finally got him.
My parking spot in Nags Head Woods Preserve.
I moved up the band a bit and started calling CQ. The cell service was poor, but I was able to use the Wi-Fi hotspot in my truck to put out a spot. It was slow going at first, and the noise was relentless. Eventually things picked up, and I worked 9 stations on 40M before things dried up.
I checked 30M to look for P2P contacts, and the noise was still there. Not hearing anyone, I moved on. The 20M band was no different, noise-wise, but at least there was more activity. I managed 11 more contacts before deciding to declare victory and pack up. Right before I turned off the rig, I heard a Straight Key Century Club (SKCC) member calling CQ, so I had a quick contact with him.

As I was taking my antenna down, I saw the likely source of the noise I had been hearing. When I first pulled in, I didn’t notice the power lines that crossed the parking lot. On the other side of the parking lot from me, there was a utility pole with two transformers on it. As I started back down the gravel road to leave, I noticed a large transformer not far from the parking lot. No wonder it was noisy there.
Wetlands in Nags Head Woods Preserve
After an hour of operating, I had 21 contacts in my log, including four park-to-park QSOs. Once again, I had no DX contacts, but I did work two California stations on 20M.

I took a short walk around the Preserve before leaving. It’s a fascinating place that definitely warrants further exploration in the future. There are wetlands and several beautiful trails with some really cool wooden bridges. Maybe next year, I can talk the grandkids into going on a nature hike there.
And That’s a Wrap
After a few final QSOs on Saturday, it was time to take down the antenna and pack up the radios. Our week on the Outer Banks was over before we knew it. Time flies when you’re having fun, I guess.
Sunset over Currituck Sound
The sloper antenna I used at the rental house did pretty well, even with the geomagnetic storms over the first day or two. I had room to accommodate a longer wire, so next year I’ll pack 36-foot and 44-foot wires and give those a try. This is our last year renting this house, but I’m sure I can make the sloper work wherever we end up next year.
It’s been a while since I’ve done a cheap speaker wire antenna, so here’s another one for you. Back in the early to mid-2000s, an antenna commonly referred to as the “No Counterpoise Antenna” was making the rounds on the Internet. I thought I might give it another look.
The No Counterpoise Antenna is either a 25-foot or 50-foot length of two conductor wire with half of one conductor removed. Essentially, it’s a radiator fed through a balanced line feeder. The 25-foot version is said to cover 20M through 10M, while the 50-foot version is supposed to cover 40M through 10M. It was usually connected to a balanced tuner of some sort or sometimes fed through a 4:1 balun. It was typically constructed from zip cord or speaker wire. So, this is perfect for another speaker wire project. (Actually, I built the 50-foot version years ago, but I don’t recall ever putting it on the air.)
A picture is worth a thousand words, so here goes:
I’ve seen this antenna sometimes referred to as a Zepp. A true Zepp is basically a half wave radiator with a quarter wave balanced line matching section. Unlike a true Zepp, the No Counterpoise Antenna is non-resonant, so I guess it’s actually “Zepp-ish.” Because it’s non-resonant, a tuner is required for this antenna.
I did some extensive research into the origins of this antenna. (OK… I just did a few Google searches.) Jeff Imel K9ESE came up with this design. I remember Jeff used to sell a high-quality version of the antenna on eBay. The reviews were generally positive.
Pete Millis, M3KXZ, is another name often associated with this antenna. I think that’s how I first came across it. Pete once made a phased array from two 25-foot versions.
In the August 2020 edition of Ozark QRP Banner, the Four State QRP Group’s newsletter, Terry Fletcher, WAØITP, had a nice write-up about it. He discusses his experience with both the 25- and 50-foot versions.
This antenna design has been around the block a time or two. So, there’s no innovation here on my part whatsoever.
Construction
I happened to have a 25-foot roll of #18 awg speaker wire on hand, so this time around, I opted to build…you guessed it… the 25-foot version.
Construction was about as easy as it gets:
I split the speaker wire halfway and cut off one side
Next, I twisted a loop at the end of the single wire and secured it with some Goop® adhesive. As an alternative, you could just tie a loop at the top or crimp a ring lug over the wire’s insulation.
I stripped and tinned the wires at the feedpoint and installed spade lugs. You can just strip and tin the wires, if you like.
To keep the speaker wire from splitting further, I put some heat shrink tubing a couple of inches up from the lugs. I also added a dab of Goop® in the middle of the antenna where one side of the wire was removed. All of this is completely optional.
Construction probably took me all of 15 minutes or so. That doesn’t include allowing the adhesive to cure overnight. However, the antenna was certainly usable without the adhesive and heat-shrink tubing I used. I’m just prone to overkill.
On the Air
To test the No Counterpoise Antenna, I drove down to Ridley Creek State Park (US-1414, KFF-1414). Using my drive-on mount, I supported the antenna from a 28-ft Jackite pole. I used a homebrew 4:1 unun at the feedpoint and ran 15 feet of coax into the cab of my truck to my KX3 (5 watts, CW). I used the long side of the antenna as the radiator.

Before I got started, I checked to see how the tuner in the KX3 would handle the antenna. The KX3 easily found a 1:1 match on all bands from 40M through 10M. Just for the heck of it, I tried 60M and 80M. The KX3 was able to find a good match on those bands, too. (That’s not too surprising, given that I once forgot to attach my coax to an antenna, and the KX3 still found a match.) I doubt this antenna would work well on 60M and 80M—but stranger things have happened. I wasn’t able to try it, but I’m sure the KX3 would be able to match it directly connected to the radio without the 4:1 and coax.
I used a 4:1 unun at the feedpoint
Band conditions weren’t very good, so this wasn’t an ideal test. Despite the mediocre band conditions, I logged 13 contacts during my short activation. Most of my contacts were on 40M. There was considerable fading on 30M and 20M, but I made a contact on each of those bands.
This was hardly a rigorous evaluation, but the 25-foot No Counterpoise Antenna got the job done. I need to give it another try, when conditions are better.
Anyway, if you have some speaker wire and a few minutes to spare, give this one a try and see what you think.
I recently learned of the passing of my old friend, Carter Craigie, N3AO. He was an avid QRPer, an excellent CW operator, and one of the nicest people I have ever met.
I first met Carter sometime back in the 90s, when we were members of the now-defunct Eastern Pennsylvania QRP Club (EPA-QRP). Later on, Carter and I were members of Chester County (PA) ARES-RACES. Carter served a two-year stint leading the organization as the Emergency Coordinator (EC).
Eventually, Carter and his wife, Kay N3KN (former ARRL President), moved to Blacksburg, Virginia. Although I rarely saw him in person after that, I had a bunch of QSOs with him over the years. He was a regular participant in QRP field contests, like the NJQRP Skeeter Hunt and Flight of the Bumblebees. He was also an active member of the Straight Key Century Club (SKCC).
In 1999, Carter N3AO and Ed WA3WSJ stopped stopped by my campsite in French Creek State Park (PA) to check out my new camper. L-R: WA3WSJ, WB3GCK, and N3AO.
Looking back through my logs brought back some memories. Carter always tried to work me when I was out camping or traveling. He seemed to know my go-to frequencies and operating habits and would always seem to find me. I remember being on a camping trip to the Thousand Islands in New York back in 1999. I turned on the radio one morning, and without touching the tuning knob, the sound of Carter calling me greeted me. We had some nice rag chews on those trips.
I had the pleasure of running into Carter and Kay during Phillies spring training in Clearwater, Florida, in 2009. L-R: WB3GCK, my (far) better half, Kay N3KN, and Carter N3AO.
During the year-long National Parks on the Air (NPOTA) event in 2016, I used to text Carter whenever I was out activating a park. Within minutes, I would hear Carter calling me for a contact. He would always make sure to spot me on the NPOTA Facebook page.
While it’s sad to know that I won’t hear Carter on the air anymore, I feel truly blessed for having known him. Rest in peace, my friend.
