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.
The purpose of this circuit is to increase the sensitivity of a galvanometer, making it possible to...
We found this configuration in documentation from the 1980s. It applies to almost any operational...
This circuit shows how to use a 12 V regulator to obtain a higher voltage output. The...
