Found in an Elektor from the 90s, this circuit converts signals from the 280 kHz band to 516 kHz, making it possible to tune them in common AM radios. The components used are from that time.
This circuit was found in a 1980s documentation for amateur radio. The circuit makes use of...
A positive transition in the trigger makes the outputs change state and remain so for the time...
This traditional transistor source uses only two transistors found in a 1998 documentation. The...
