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 monostable or one-shot circuit was found in an American publication from the 60's....
This output step with a transistor can be used in experimental radios and intercoms or as a signal...
In the figure we have 3 monostable circuits for triggering without rebounds of CMOS circuits. The...
