The two circuits shown show how to obtain an SSB / CW control for receiving this signal top at a common receiver. The circuits were found in an old American manual from the 80's.
This is a traditional configuration for a photodiode amplifier using an operational amplifier. The reverse...
We now present the 4013 in its bistable configuration, in which we use 3 flip-flops (1 and a half...
