Conrad Bridges was an active on AMer on the low end of 75
meters from the early 60s to the early 70s. He was quite a character and
anyone who hung out on 75 and ran across Con would be sure to remember him.
Once he was cited by the F.C.C. for using what he called his "wobbulator"
which was nothing more than a small motor running at a slow rpm and turning
a capacitor attached to his vfo. It was quite effective at discouraging
sidebanders although it was illegal.
