A Secret Little Adventure Ham Radio Blog
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 …
Potentiometers for crying out loud…what the heck did you think I was talking about?!? And don’t get any ideas that you caught me here. I am a well-established straight-edged teetotaler.

Oscilloscope. Signal generator. DC power supply. DMM. LCR meter. A trunkload of components. A still non-functioning diy fuzz face guitar pedal…
Look carefully at that radio in the picture above? Recognize it? I’ll come back to it at the end of this post. The odd places radio takes you. Below is Pocumtuck Rock in Deerfield MA. It is the same place the picture above was taken. The WGAF-FM tower sits above the Eaglebrook Boarding School. It …
