This circuit was found in an American 1980s documentation. The transistorized step is the receiver's last IF and the diode is the receiver's existing detector.
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...
