Tech Stuff

From 1958 to 2008, Pat Hawker authored hundreds of “Technical Topics” articles in RadCom, when I received my copy it was the first thing I read. This page is inspired by him, lots of both long and short bits and pieces, often unrelated and in random order about technical, radio related subjects.
I have started thing off but would welcome your input, even one paragraph about a relevant subject would be welcome. Pictures and/or video would be good.
