This low power circuit for the FM band was found in a spy book from the 90s. The tunnel diode is not an easy component to obtain and the power can be supplied with a single button cell.
This is one of the first circuits published on this component. We found it in the September 1950...
Found in American documentation from the 90s, this circuit uses a high voltage relay and has no...
This circuit generates high voltage pulses, which can reach 30 000 V with the discharge of a...
