Bug-Out Month Begins! My First Field Activation with the Vibroplex Original Deluxe As I mentioned in a previous post, I declared October, 2025 to be my Bug-Out Month. I did this primarily to motivate myself to get comfortable using a bug—a semi-automatic key—not just in the shack, but in the field as well. I was inspired by several things that happened over the past few months: my buddy Kevin gave me a vintage Skillman bug; I spent way too much time with friends at the Long Island CW Club booth…

QRP POTA: Will the Elecraft KX1 pair with the AX3? (Of course it will!) by Thomas (K4SWL) The afternoon of Wednesday, September 17, 2025, was just calling out for a POTA activation. I didn’t have enough time in the day to travel further afield than my local Blue Ridge Parkway—my park-away-from-home these days—so I headed there with a field kit packed in the car. In mid-September, I was still dealing with some lower back pain.

Hurricane Helene: One Year Later One year ago today—September 27, 2024—Hurricane Helene moved up from the Gulf of Mexico, swept across the Southeast, and struck Western North Carolina.

KV4AN: A Pair of Quick Drive-Up SOTA Activations in Northern Alabama By Steve (KV4AN) My XYL and her sister like to go yard sale-ing on Saturday morning (this is the practice of buying other people’s junk so you can throw it away for them), so I’ve had two beautiful Saturday mornings to do a pair of quick drive-up SOTA activations here in Northern Alabama.  The first Saturday, I went to Gunters Mountain, which is around an hour away near Swearengin, Alabama.

Compromised Antenna? Not Today! AX1 Activation at Fort Dobbs State Historic Site On Tuesday, September 9, 2025, my wife, Hazel, and I were heading back from Greensboro, NC along Interstate 40 when I thought it fitting to make a short detour to Fort Dobbs State Historic Site for a quick POTA activation. Fortunately, both my wife and Hazel agreed. We all wanted to stretch our legs, and Fort Dobbs is a wonderful park to do just that.

KI5OEB: Testing the “Just OK Mini” Antenna in the Field by James (KI5OEB)  Testing, testing, testing!!! On September 22, I went out for a few hours at Cherokee Strip Regional Heritage Center Historic Site (US-10951), my closest park… I open this by stating the objective of this activation was testing the Ham Radio Duo “Just OK Mini” antenna.

KB2PIZ: Activating Saltwater State Park (US-3262) by Mark (KB2PIZ) I've been on another business trip to Seattle and had some free time to visit Saltwater State Park and complete an activation. I was here last year and only made one contact before I had to leave. This year, the plan was to stay until I completed the activation. To ensure success, I packed the trustworthy Chelegance MC-750 and the Chameleon end-fed sloper.

Labor Day, Family Time, and a Bit of POTA Therapy: QRP DX at Jordan Lake Educational State Forest by Thomas (K4SWL) My wife and I hatched a plan for Labor Day weekend: pack the car, head to the Raleigh, NC area, and spend the long weekend with our daughters, who were just a few weeks into their first year at university. I’m sure they were glad to see their loving parents—but let’s be honest—they were most excited to see Hazel.

Jordan Lake POTA with Roger, and a Surprise QSO with Leo in Germany! One of the joys of writing up field reports is reliving POTA and SOTA activations. Since our travels in Canada this summer, our family has had a lot of irons in the fire. My available time has been almost non-existent, so I’ve only managed a handful of POTA activations. What I didn’t get in quantity, though, I certainly made up for in quality.

One of My Favorite Places on Earth: An ATNO POTA Activation in Tadoussac, Québec There are few places on this earth that I love more than the region of Québec around the town of Tadoussac. Tadoussac sits where the Saguenay River—really, a dramatic fjord—meets the mighty St. Lawrence Estuary. Long before Europeans arrived, the Innu people had used this place—known to them as Totouskak—for thousands of years as a seasonal base for seal hunting and trade.

Red Oxx Gator EDC Field Kit for the Lab599 Discovery TX-500 by Brian (K3ES) I am blessed to be able to afford a number of terrific QRP rigs to support my portable operating habit (or is it an addiction).  Every rig has its own advantages and disadvantages, and my operating skills grew as I became familiar with each of them.

Watch Out: “Gift Card” Scam Emails Targeting Hams by Thomas (K4SWL) Lately, I’ve been receiving emails that look like they’re from ham radio friends — complete with their name and callsign in the “from” line. At first glance, they seem legitimate. But when you check the actual email address (not just the name that shows up in your inbox), it’s clearly not from them. For example, the "from" line might read, "Thomas (K4SWL)" but the email address is something more like abc4567@gmail.com.

Back-seat QRPing: A Morning POTA Activation at Cap Tourmente On Sunday, July 6, 2025, I ventured out in the morning—despite the forecast calling for wet weather—to my favorite local activation site near our home base in St-Ferréol-les-Neiges, Québec: Cap Tourmente (CA-0012). The day before, we had learned that my father-in-law had been admitted to the hospital. Details were still forthcoming, but we knew we’d need to adjust our travel schedule and return home earlier than planned.

Tackling the Magruder Corridor in North-Central Idaho by Ken (WR7D) I’m a member of the All-Idaho Contest Club (AI7ID) in Southwest Idaho. Occasionally, we plan other ham-related activities. In June, we started discussing a potential trip through the Magruder Corridor in North-Central Idaho for some POTA and SOTA action. The Magruder Corridor is a rough, single-lane road between Grangeville, ID, and Darby, MT. It separates the Selway-Bitterroot Wilderness Area and the Frank Church River of no Return Wilderness Area.
