This circuit assumes that a pulse produced by S1 has a constant duration determined by R1 and C1.
Here we show an oscillator that uses an LC network. The upper limit depends on the power-supply...
This oscillator can generate 2 to 10 MHz signals and was found in an American 1980s documentation. The...
The idea of this simple circuit is to use a tape recorder to key a transmitter in code emission....
