Portable SDR with built-in antenna analyzer

pSDR

As I read the web site and watch the embedded videos, I am of course interested in the technology described – but perhaps even more interesting is the age of the ham involved. We often hear about the “graying” of ham radio and I’ll be the first to agree with those who say that the hobby…

Why not a “smart” autotuner?

Three decades ago, every issue of QST had an ad from Palomar Engineers with exactly two products being pushed – a VLF converter and a noise bridge. They looked quite similar in identically-sized bright red housings. I bought the VLF converted and had a lot of fun experimenting with it. As for the noise bridge –…

The first 25 entities with Mountain Topper QRP

KD1JV's MTR (Version 2) - same size as deck of cards.

I’ve decided to return to my QRP roots for a while with the goal of working DXCC with my KD1JV MTR rig. The log/details of the progress will be kept up to date here. I’ve had it on the air exactly one week now and have just finished working the first 25 entities in 4 separate…

He was operating simplex with only three…

MTR lives! (Thanks, Steve KD1JV)

As careful as I was in building the latest kit from that creative genius known as Steve Weber KD1JV, I had a flaw somewhere and couldn’t get the past the initial steps of aligning the completed kit. I’ll spare you all the details of how much midnight oil I burned looking for the fix –…
