I am in the process of configuring a pair of Icom IC-706MKIIG transceivers for Full Duplex U/V and V/U satellite service. They will be controlled by SatPC32 with one being the transmitter and the other the receiver.
This will require switching the duplexer-separated UHF and VHF input/output between the UHF and VHF antennas. I would like to control the coax switches automatically to avoid human error. I am looking for a signal, either from SatPC32 or the transceivers to switch the relays between U/V and V/U modes. The transceivers have a signal on the 13-pin DIN ACC socket pin # 5 labeled BAND with the description “Band voltage output. (Varies with amateur band) 0 – 8.0 V” No other details. Does anyone have any additional information on this signal? Is there another signal available from SatPC32 or the transceivers that would enable automatic switching between U/V and V/U?
