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, which is also a leak meter, has a detection resistance of billions of ohms. We found...
With the precision given by the crystal this circuit provides signals of several frequencies for the...
