Hi, I'm new here, I have a little problem, I'll be grateful for the help. It happens that I want to modify the circuit of an FM audio transmitter, so that instead of transmitting audio can transmit a signal to turn off or turn on a switch, and the switch on and off an LED, the idea is to communicate using Morse code using the FM frequency. What could be modified to do this?. What could be change to a conventional radio receiver, so that instead of playing audio, will have a led (for morse code communication)?.
This is the transmitter diagram.
Thank you.
