[amsat-bb] Icom CI-V programming

Erich,

Thanks for the insight. It looks like 07 B0 is what I was overlooking, thanks for pointing it out.

The specified VFO will automatically accept VHF, UHF and L frequencies  (if you have that module). The command and sub command bytes for the IC-910H in non-satellite mode are: VFO A: 07 00, VFO B: 07 01. Satellite mode Main VFO: 07 D0, Sub VFO: 07 D1. Of course, you need  to send always the complete command string incl. header and FD as terminator, see manual p. 78/79.

After a few struggles with the manual being either wrong or missing information I’ve run into what could be a potential problem later. When using command 0x00 to set the frequency, the rig will not switch bands on its own. Whether this makes sense or not is debatable and I have a couple possible workarounds, some uglier than others. I can either read the bands that Main and Sub are on and send my 2m and 70cm frequency to the correct place (elegant) or I can send them both the same frequencies and let the rig sort it out (ugly). Now comes the tricky part. I don’t have the L band module yet but when I do, how am I supposed to get the rig to switch from say L/v to U/v if it doesn’t auto switch bands?

I would also be curious what users of SatPC32 experience when they switch between L/v and U/v. Do you manually have to switch bands to regain frequency control or does the IC-910 become smart enough to switch on its own when the module is installed?
