This circuit can generate signals in the VHF range and can be used as the basis for small transmitters. The frequency depends on the coil, which can have 2 to 8 turns for the range of 50 to 200 MHz.
This circuit was obtained in a 1975 documentation. The maximum frequency depends on the diodes and the...
Found in a 1990 Hobbyst Handbook this circuit has an output power of a few tens of watts and...
The circuit shown is a constant current source which allows the reading of resistors on a very low...
