A Secret Little Adventure Ham Radio Blog
(New follow-up post here!) How hard could it be to construct a little band pass filter, throw a signal through it, and see if it properly attenuates? A breadboard, a small handful of components, an online filter design tool. Fifteen minutes, tops? I was longing for the pleasurable jolt of satisfaction that one only gets …

Along my journey on understanding radio, electronics, and in particular, the magic of baluns, ununs, and other transformers, I came across this helpful video on how to analyze a 49:1 unun with a NanoVNA. I replicated it with the the “Alleyway Antenna” transformer. This one below…unfortunately I did not take a lot of pictures of …

It was only a few short years ago that I texted a friend of mine in a panic because I had chipped the corner of a ceramic capacitor (probably a 103 or something like that). I had spread its little wire legs too far apart while trying to put a through hole CW transceiver kit …
One of the best parts for me about maintaining this blog is being able to see my own progression within the amateur radio (and electronics) hobby. About a year and a half ago, I published my first attempt to breadboard a receiver (here). It is rather painful to look at. And it did not work. …
By now it should be pretty obvious that Summits-On-The-Air, and attaining its elusive Mountain Goat award, is hard for New England activators. Summertime hikes up any given mountain with four successful summit QSOs, are only worth a maximum of 10 points a piece. And these 10 points are only reserved for the northeast’s most challenging …
