[GreenKeys] on-off radio teletype (not FSK)

[Richard Knoppow]

     I searched You Tube for a recording of the old jamming 
stations but couldn't fine any. It was something like the noise 
of putting a sheet of cardboard against a fan blade. Hard to 
describe. I heard the multiplex stations but they were quite 
different. I could use the crystal filter on my old Super Pro to 
separate some of the signals, at least enough to tell they were 
FSK of some sort. Some of the signals were very strong and very 
constant, maybe RCA at Bolinas or maybe the Navy at San 
Francisco. Anyway something not too far away.
