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.
We found this circuit in a 1968 Electronics World. The potentiometer should be set to trigger the SCR...
This circuit generates signals from 50kHz to 10MHz, depending on the crystal used. The transistors can be...
This simple light relay circuit was found in a 1988 documentation. The base is the operational 741 which has...
