[Boatanchors] Electronic TR Switch?

[Ed Swynar]

Hi Steve,

If it's anything like the 6AH6 unit I built when I was a novice some 30
years ago, throw it as far away as you are able to throw it!

Mine was responsible for the only personal visit I ever had from the
government licensing people, due to severe TVI the thing caused to a
neighbour half a block away from my parent's house...
