I notice the use of sidetones, and receiver muting does not seem to be commonly used in separate operation on the same frequency. Obviously sidetone would be needed when operating on different transmit and receive frequencies.
I have often wondered about the lack of sidetone circuits in vintage transmitters. I have always had transcievers and sidetone, so it all just seems odd to me. :-) 73, Darrell Bellerive Amateur Radio Station VA7TO On 06/17/11 10:18, Paul Christensen wrote: > The beauty of this system is that the PIN diode switch allows just > enough Tx to Rx leakage for one to get about a 10 dB over S9 signal on > the receiver while transmitting in CW.
