[time-nuts] time-nuts Digest, Vol 169, Issue 40 SRD ideas

[Wes]

My recollection is that the Gunnplexer used (no surprise) the same Gunn 
oscillator for TX and as the LO. The RX mixer was a regular point-contact 
diode.  For communications use they operated in pairs with the oscillators 
offset by the i-f.
