This circuit, very critical due to the frequency at which it operates, was found in an American documentation that uses a resonant cavity in a beer can. The transistor can be of any type for RF.
This circuit was found in the April 1973 issue of Radio Electronics magazine. Using TTL...
This receiver receives signals in the 17 MHz or 11-meter range and can be used as a base for an...
We found this circuit in a 70s publication. Transistors are general-purpose types of the time. The...
