A day at Wildcat Mountain
I mainly went out to Wildcat Mountain to test and adjust my wire antennas, so I brought a couple of radios, all of my antennas, and a variety of test equipment. I set up just off the upper parking area near one of the trailheads of Old Settler’s Trail, which is one of my favorite…

Homebrew EFHW from scratch
I have been thinking about making a couple of minimalist EFHW antennas with SMA connections for use with the (tr)uSDX. After weeks and weeks of out-of-stock conditions for my preferred kit, I ordered up some parts and started to make one from scratch. Starting with an FT50-43 toroid core, I wound the 49:1 unun: The…

projects, projects, projects… so many projects …
Since I finished off those half-built kits a few weeks ago I have been purchasing a variety of electronic parts to start a new round of projects; here is a representative collection of them, tastefully arrayed in a cardboard flat (which is one of my favored containers for organizing projects on the workbench). I have…

A gear bag post
All winter, and well into the spring, I was operating from the car; only rarely was my radio pack used for anything but carrying to and from it. I wasn’t entirely satisfied with either of the existing packs, they exemplified the old saying about “the two standard sizes; too big and too small”. Operating portable…

Field Day, Day 1
My planning for Field Day was kind of sketchy, and not at all ambitious, so I grabbed my radio pack after lunch and arrived at Wildcat Mountain State Park a bit before 2:00, or already almost an hour into the event. It took me about 20 minutes to set up the X6100 and the 20…

If it’s mid-June, then Field Day is right around the corner
is the thought that occurred to me this morning. Fourth weekend in June, yup, 24th and 25th, okay; I think I’m going to try for something a bit more organized than last year. But what, exactly? Well … weather permitting, definitely QRP, definitely carried in the pack (see the upcoming post about my current station-in-a-bag),…

Off to Oak Island!
Up early, final packing (and unpacking!) almost finished. This is just a quick post before I turn this off and pack it up. This Lenovo Chromebook running Linux Mint is the only device that I have no means of charging for the next couple of days, so battery conservation will be crucial (assuming that I…

X6100 and EFHW at Wildcat Mountain
The weather today was a lot more pleasant than when I last activated K-1480, but I was using the same equipment. I planned to trim a few inches from the QRPguys EFHW to improve the SWR while I was setting up but it seemed to have the opposite effect … now I am wondering what…

It was snowing lightly on Wildcat Mountain …
as I worked 24 hunters this morning at Wildcat Mountain State Park, K-1480. It drizzled all night, on & off, it was still drizzling as I loaded the car and drove to the park; as I was unwinding the antenna wire I saw the first few snowflakes. There was a brief period of snow pellets,…

Making a common-mode choke
Over the winter I bought a couple of different EFHW antenna kits, not all of which are assembled yet. (More about these in the weeks & months to come!) I have been wishing for a common-mode choke to work with them because of all the stories that one reads about RF-on-the-coax-shield interfering with the operation…

Coulee Experimental State Forest, K-5578
Woke up this morning thinking “activate a new park today”, but which one? In the end I decided to try Coulee Experimental State Forest, K-5578 again. (for my previous attempt, click here). It was an ideal day for a wire antenna and I quickly hung my 20 meter dipole from some sapling trees and turned…

Slingshots
I have always liked a slingshot of one kind or another as an aid to getting a wire up in a tree. I still have the Wrist-Rocket that I bought from L. L. Bean back when they were an obscure sporting-goods store in Maine, and it has served me well all of those years, (allowing…
