We found this circuit in a Radio Electronics from the 90s. Transistors admit current equivalents, especially the power one that is not a common type today.
Unlike the previous one, this circuit is intended for the reception of frequency modulated signals...
Found in Electronics now from the 90s, this circuit uses a sensor from the time, which is...
We obtained this oscillator in a publication for radio amateurs in 1978. The circuit operates on...
