Hi Fran & all In none satellite mode use: Main mini din for tx audio and ptt (same for 1k2 and 9k6 ) and the sub mini din for rx (this can be configer for 1k2 or 9k6 baud) (ground from both to sheld the signal) If u want to use main band only (eg in ISS ie1k2 ) disconnect the sub and supply the audio to PC from headphone jake. Also you can use ACC where you can reprogram the pins from the menu. More easy ! built a distributing box with all terminal to play with. 73 de Nader st2nh
