BUT The big question is , What can you transmit ? I assume the amplifier is class d/e ... Are you able to translate a audio based data mode to 136, the opera data mode is designed to allow access to data/beacon with simple CW transmitter and is not as efficient as mfsk or phase modulated system ...
