For one, its almost midnight. Look at all of those signals on the data portion of the 20M band!!! I may actually be a believer in Solar Cycle 25. I am not shocked. A few nights ago, this is what my ZachTek WSPR unit looked like on 20M. So I put about an hour and …
Life is such a meandering journey. Back in January 2021, when AA1F was still WX1MAR, and this blog was in its infancy, we rented the Caboose at the Chester Railway Station & Museum for Winter Field Day. It was an extremely cold stay with single digit temperatures. The post is here and the throwback photo …
This will not be an easy post to write. There are far too many RF and electrical concepts cemented together with way too little foundation of knowledge on my part. It is a continuation in some ways to this post. And a bit to this post. And it fueled by some challenges posed by my …
Lets start with the fact that there is no S2 port on the NanoVNA. There is a “1” port. And there is a “0” port. Or lets talk about that S12 measurements tell you how well a transmission goes from port 2 to port 1. NOT how well the power of the transmission goes from …

I came back from NEAR-Fest at the Deerfield Fairgrounds in New Hampshire two weekends ago with a box of variable resistors that only cost me …
Fuzz Face built on a perf board with an additional LED and a switch added into the circuit. Best part? After transferring from breadboard, the darn thing still works! Oh yeah, the enclosure is a sandwich-size tupperware container.
There was snow. I only wore my crocs, my hiking shoe of choice but not for a foot of slushy, melting spring snow. It was 50 degrees. The peak of Slide was 2.8 miles away. Rock hopping up the base of the mountain made the early part of the trail easy. The trail was soupy, …
You may recall in this post, that AA1F and I were shut out of getting our SOTA point on Oak Hill W1/MV-006 near Concord NH due to a thunderstorm. This meant that I could not attempt to put that rusty twisted tangle of metal residing on the peak of the small hill on the air. …
[Update: I included some audio files of me on the electric ukulele. Don’t laugh too hard!] Of all of the places I expected ham radio to take me, audio engineering was definitely not one of them. I am not much of a musician, though I can strum a few chords rather choppily on the ukulele. …
