[GreenKeys] Fredrick Electronics Demodulator

[Richard Knoppow]

     The Fredrick Electronics FSK demodulator is advertised 
in the September, 1966 issue of QST p.145. It claims 20 to 
30db improvement over other demodulators and a patented 
"decision threshold computer". Is anyone on the list familar 
with this thing, I wonder what they were actually doing and 
if it really had any advantages. I will try to find the 
patent later.
