In Mike’s first video, he describes the evolution of the POTA20 (and Carbon 6) ground spike system and its variations. As you’ll see, quite a lot of thought and engineering went into this simple design:
In this video, Mike demonstrates how you can easily hack a portable camera tripod to support a carbon fiber mast.
As Mike notes, “It’s a bit more to fiddle with than just a spike. But in the frozen north you have to deal with ground conditions. Get yourself a cheap tripod and give it a try. Will also work well when the park will not let you stick anything in the ground or use a tree.”
Yesterday morning, I replied to a message from a reader planning to obtain a vanity callsign. He asked, “Which [suffix] letters would make an easy callsign to send [in CW] and copy in your experience?”
This is a great question. I do have a few suggestions.
My previous call
I suggest avoiding ending your callsign with a “K.”
I speak from experience.
I was not an avid CW operator when I upgraded to General over two decades ago. I was auto-assigned the following callsign by the FCC: KF4TZK
It was a mouthful in SSB, especially when articulated phonetically: Kilo Foxtrot 4 Tango Zulu Kilo.
When I started operating in CW, I realized how confusing it can be to have the letter “K” at the end of one’s call. If your sending isn’t near perfect—or even when it is—people will assume the “K” is simply “OK, back to you,” and they copy “KF4TZ.”
I got tired of correcting my call by sending back “KF4TZK K” to let them know the K was part of my suffix.
If your call ends with a K, there’s no reason to change your callsign unless you also find it gives you trouble. If you have a ‘2 x 1 call (a callsign with two letters, a number, and a letter) ending in K, it’s not a problem.
I would also suggest not combining too many letters similar in dit patterns, like “HSI” or “HSH.” Strings of dits can be complex for some to copy.
Best advice?
When I decided to apply for a vanity call and ditch KF4TZK, I consulted my dear friend and wise Elmer/mentor, Mike (K8RAT).
He said:
Write down all available callsign options you’re considering, then practice sending them. You’ll know which one “feels” right.
He was spot on: K4SWL felt right, and since SWL (shortwave radio listening) is what started my radio journey, it was a no-brainer.
If you feel comfortable sending a callsign—if the rhythm and cadence feel right to you—then it’ll likely be easy to copy on the other end.
Final thoughts
Remember, this is a fun and creative process. Enjoy the journey of deciding on a new callsign!
In the end, very few “bad” calls are out there. It’s incredibly rare that I copy a call and think, “Wow—that’s a stinker!”
Even if your call sounds a bit awkward in CW—many do—rest assured, others won’t have difficulty copying you if your sending—your pace and spacing—is accurate.
What do you think?
Do you have any suggestions? Feel free to comment.

CFT1 Field Kit
by Jonathan (KM4CFT)
I thought I would supply my own field kit I recently put together for my CFT1.
This will also be the official announcement of my newest product, which is a CW Key leg strap. The leg strap is something I originally got my dad to fabricate for me out of some scrap metal a while back, and now that I have the version 2 iambic paddles, I thought it would be nice to mass-produce them. They are compatible with any magnetically mounted paddle.
This is my CFT1 Go Bag. It contains everything I need to activate my CFT1 except for a mast or throwline.
The kit consists of the following:

Fall weather has finally returned to Savannah, Georgia so it is time to get out for more Parks on the Air. Monday, November 18, I headed to a park I had yet to activate – the Savannah National Wildlife Refuge (US-0522).
This park and I have history together prior to my involvement in ham radio. In my 20’s, I volunteered for the U.S. Fish and Wildlife Service and spent time at this refuge in various capacities. I was also employed by a gentleman who owned Fife Plantation, property adjoining this refuge. I was his “eyes and ears” at meetings held to discuss deepening the Savannah harbor and study/assess the environmental impacts of that effort. Those meetings taught me much about the refuge and its relationship with industry across the Savannah River. To return to this park as a ham added yet another chapter for the refuge and me.

As much of the refuge is wetland accessible only by boat, the easiest way to experience this park is to drive the Laurel Hill Wildlife Drive, accessible from SC Highway 170. This drive is a loop through the southern impoundments that are managed for resident as well as migratory bird populations.

After you turn onto the wildlife drive, there is an information kiosk to the left with maps and an informative display regarding the history of the site.

The land on which the refuge sits was originally occupied by the Yamacraw Indians. Later it was used for rice cultivation, being built and maintained by enslaved African Americans as well as immigrant Irish laborers. The rice culture in the area collapsed after the end of slavery and increasing competition. The 2,352 acre refuge was established by President Calvin Coolidge in 1927. Today, the land is managed to provide habitat for waterfowl and other wildlife and is the largest federally protected tract of land on the Georgia coast.

This particular morning, the air was crisp (in the lower 50’s) and I had the park (for the time-being) to myself. As I prefer to use a wire antenna and had brought with me the Tufteln EFRW, I needed to find a tree in which to install that antenna. As you can see from the photos, there are not many trees to be found here. However, dotting the wildlife drive are what are known as oak hammocks.

Oak hammocks are little islands of high ground amongst the wetlands and they are populated by hardwoods such as oaks. There are quite a few along the western section of the wildlife drive. I decided to use the first sizable one I encountered. Utilizing this as my QTH allowed me to park and set up well off the drive. At most parks I visit for POTA, I rarely see anyone. That is not the case here since the park is located not far from downtown Savannah, a popular tourist destination, and it is easily accessible by car.

Even though my Marlow arbor line typically doesn’t hang up in trees, I think oak trees present lots of opportunity for that to happen with their myriad twisty twigs and Spanish moss so I prefer to avoid them. But, if I want to put a wire up in this park, oak trees are about my only option. The particular tree I considered would allow me to run my antenna northwest and away from the drive. That location would also provide shade from the sun through most of the morning.

Once my antenna was installed and I was comfortably settled, I got down to business – the reason I was here: an activation!
Forty meters was not an option due to RFI. That was not surprising given the industry across the river and the presence of monitoring equipment, etc. in the refuge. So I began with 30 meters. Not long after I called CQ, Sean N3RTW answered and the fun began! Continue reading The POTA Babe Reconnects With Her Past→
Earlier this week, I mentioned that I purchased a Xiegu G106 in September. Its delivery was delayed because I had it shipped to my local post office, which, as you likely know, was flooded during Hurricane Helene.
With all the post-Helene chaos, I haven’t been able to do as much POTA as I’d like, so the G106 sat unopened in its box—until Wednesday, November 20, 2024, when I finally had a chance to take it out for its maiden activation at Lake James State Park (US-2739)!
Why the Xiegu G106?
Last year, Radioddity sent me a G106 on loan, and I wrote an in-depth review after taking it on several activations. That review was lengthy because radios like the G106—designed as price leaders—often have compromises that may not suit everyone. It’s essential to judge such radios based on their goals, not by comparing them to premium models like the Icom IC-705.
For the G106, the question I aimed to answer was: “Does this radio accomplish what it sets out to do?”
I believe its mission is to offer affordable field radio fun—capable of completing park or summit activations without excessive struggle, providing performance commensurate with its price point.
I decided to purchase the G106 because I had returned my loaner unit over a year ago, but questions about it kept coming from readers. Instead of requesting another loaner, I opted to buy one.
To my surprise, the pricing had dropped significantly. Here’s my order confirmation:
Interestingly, as I mentioned earlier this week, Amazon (at time of posting) has a Black Friday deal for the G106 (without accessories) $199 shipped for Prime members[QRPer affiliate link].
I’d have chosen that over the bundle I ordered had it been available at the time.
Unboxing to Activation
It was a rainy day at Lake James.
A common question from readers has been, “Would the Xiegu G106 work as a dedicated field radio for POTA activations?”
Perfect weather to set up in a picnic shelter!
Most of these inquiries came from newcomers to ham radio, so I decided to test the radio in the field by setting it up from scratch—straight out of the box. This included attaching connectors to the power cord, configuring the radio, setting up the antenna, and hopping on the air.
This is a lot of picnic shelter for such a small radio setup!
I started the activation using SSB (voice) and later switched to CW (Morse Code) to give a full “out-of-the-box” experience.
The resulting activation video (below) is lengthy but was incredibly fun to film!

Hi Thomas
For what it’s worth, here’s an easy, cheap, very lightweight, multi-band, no counterpoise antenna for portable ops.
This build took place on a rainy day at a campground in an 18ft RV and was inspired by an article written by Craig (WB3GCK): No Counterpoise Speaker Wire Antenna.
This antenna can be set up as an inverted V or inverted L.
I cut a 30/20 ft version to hang on a 32ft Jackite telescoping fiberglass mast. I read that several ‘random’ lengths, the 50/25 and 25/17, have also been successful.
Cut a 30 ft length of speaker wire (do not peel or separate it yet), then measured back 10 ft and peel off then cut only one side of the speaker wire twin lead. This will effectively create a 30-foot antenna with a 20-foot “balanced” feed.
You will then need a “BALUN” with unbalanced input and balanced output.
My 1:4 and 1:9 did not work because both ports are single-end BCN connectors soldered on a PCB.
Luckily, I also pack an MFJ 9211 (1:4 QRPocket Current Balun).
Using a NanoVNA and MFJ-902.mod.aaz (mod to form an L-network–more info on my qrz.com page) I measured less than 2:1 SWR on 40, 30, 20, and 15 meters.
The N7DDC ATU-100 reports…
1.18 :1 SWR on 15M
1.03 on 20M
1.16 on 30M
1.88 0n 40M
It loads well.
My first 20-meter contact was a POTA contact with W4TTU (approximately 700 miles away), who gave me a 559 at 5W–he was 579 and signed “72,” so I assumed running QRP as well.
Not too shabby for an impromptu rainy day project hi hi!

Activating on the Road: Pikes Peak State Park is Where???
by Brian (K3ES)
During our road trip across the country and back (Six Weeks and 7300 Miles: Activating on the Road), Becky and I planned our route to enable me to complete at least one Parks on the Air (POTA) activation in each state across the American west. One of the first parks that I activated on the trip was Pikes Peak State Park (US-2311) in Iowa.
You heard that right, Iowa.
This was one of my favorite activations during our time on the road. I had an amazing view of the Mississippi River Valley while I was operating, and since this park was less than an hour from our final destination for the day, I had enough time to work plenty of contacts.
Molly wants you to know that Pikes Peak State Park (US-2311) is located in McGregor, Iowa.
When we arrived in the park, I took Molly the POTA Dog for a walk around the park. She is always excited about a walk (particularly after riding in the truck for several hours), and it gave me the opportunity to scout the park for a good location to set up my station for the activation. The park is located on a bluff, hundreds of feet above the river, with walking paths and overlook platforms offering great viewpoints.
A number of park visitors were enjoying the overlook platforms and the pathways, and I prefer to keep my station out of the way, so I settled on using a path-side stone bench for my activation. The bench was located under some trees that provided both shade and support for my antenna, a perfect location.
Activating US-2311
This is the bench I selected for my operating position in the park. Trees provided support for the antenna, and shade for the operator. In the background is one of the platforms overlooking the Mississippi River Valley.
When we returned to the parking area, Becky took Molly, and set out on a hike to nearby Bridal Veil Falls. I picked up my radio pack, and returned to the bench. I tossed my throw line over a tree branch, and hoisted the Tufteln End-fed Random Wire (EFRW) antenna into a vertical configuration. Laying out the 17 ft counterpoise wire along the ground, and attaching a 15 ft RG316 feedline completed the antenna deployment.
I placed my KX2 next to me on the bench, connected the feedline, power cable, earbuds, and VK3IL pressure paddles. I opened my log book, secured it to a clipboard balanced on my knee, and was ready to get on the air.
Having caught a good tree limb with my throw line, I am preparing to hoist the 35 ft radiator wire of my EFRW antenna.Here I am operating from my bench. Another of the overlook platforms is visible in the background.The view from my bench was great, and Molly came to share it with me for a few minutes before I finished the activation.
As always for new-to-me parks, I scheduled my activation in advance on POTA.app while I had a reliable internet connection. That way, I was good to go, even if cellular service was unavailable at the activation site. Since I operate in CW mode, I just had to find an open frequency and begin calling CQ.
The Reverse Beacon Network (RBN) picked me up, generated an automatic POTA spot, and calls began coming in. In truth, even when I have data service available in a park, I seldom do more than monitor continued automatic spots. The RBN even updates my spot when I change frequency or band. The RBN spotting function works spectacularly well for a CW operator, even at QRP power levels.
Results
This map shows the locations of hunters who made contact with me at US-2311.
I stayed on the air until after Becky and Molly returned from their walk. In about 40 minutes on the air, I logged 27 CW contacts on the 20m and 30m bands. The pace was steady, and I was able to work my way through all of the callers. I am grateful to each of the hunters who tracked down my QRP signal, and stuck with me to complete a contact.
During our 6-week excursion, solar conditions were stable, and propagation was great. The Tufteln EFRW antenna was quick to deploy, quick to pack, and performed impressively when paired with the KX2’s excellent internal tuner.

Final Thoughts
If you are ever find yourself in northeastern Iowa, I definitely recommend taking the time to see Pikes Peak State Park. Activate this park, if you can. The views are amazing. If you can bring binoculars, or a long lens for your camera, so much the better. We could see a large number of birds standing along sand bars in the river, but could only guess at the species.
Early fall is probably not the best time to view Bridal Veil Falls, but it should be spectacular in the spring.
Becky enjoyed the walk to Bridal Veil Falls. It involved moderate elevation changes along the trail. She was disappointed with the Falls themselves, because water flow was minimal after a dry period in early autumn. The Falls should be much more impressive in the spring.
