I am sending you, separately, the file SATPC32ISS.TXT from Erich Eichmann's excellent SatPC32 program, which explains why satellite mode on the 910H cannot be used for in-band operations such as the ISS. Split mode must be used, and an additional handshaking line is required between the computer and radio to prevent the computer from trying to change the uplink frequency while the radio is transmitting.

Hi All,

Does anyone use this radio and software control combination for same-band operations (like ISS)? I was curious if you were able to tune both the Main and Sub-Band frequencies within the same band and xmit/recieve like normal w/o full duplex operations. If so, what mode are you in when performing these operations (split, sat)?

Thanks,
