[Gpredict-discussion] Simplex RX-TX with Icom 910h

[Alex B. <ale...@gm...>]

Hello all,

I would like to use the ICOM 910h for Simplex RX-TX operation. That means,
using the same band (UHF) for uplink and downlink in half duplex operation
correcting the frequencies for uplink and downlink boith separately (maybe
in separated VFOs)

I found the following link http://wiki.oz9aec.net/index.
php/Doppler_Tuning_Algorithm_for_Gpredict but I couldn't make the Icom 910h
behaves as I want.

Also, when I read the DCD signal it gives me a 1 for SQL open and 0 for
close (transmission) which is the opposite to PTT (1 for SQL
close/transmission) which leads me to the opossite result (it swaps
frequencies for uplink/downlink)

How can I make my rig work as I want? Which configuration should I use in
GPredict?

I'm using ICOM's IC-CT17 interface to communicate mi computer with the rig.

Thank you!

Best regards,
Alex.
