The project advanced again, now, I can read the signals, and send them to CAT so i can use it on N1MM or other cat sw.

The signals, BFO, LMO and HFO are fed to a 2n3904 transistor that amplifies them and feeds 3 ports of the 7414, this is the triggered signals are then sent to the 74151 mux and fed to a divider, 74939, finally the signal is fed to a pic.

Above the debug messages.

N1MM 🙂

Amplificador.
