I’m currently working on some projects that will implement CI-V control of my rig, an Icom IC-910H without the L band module. 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’m not seeing any commands to handle this situation. Does anyone know if there is an undocumented command or some other type of workaround? 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?
Any insight into this would be greatly appreciated.

Hi Mike,
Neat project. Rest assured that both the 910 and 9100 work just fine with three bands and SatPC32, all via software without any buttons needing to be pressed. Evidently Erich DK1TB has it mastered. You might email him? He might save you some time.

Mike, before you send a command to one of the VFOs (set/read frequency and mode, Ctcss-tone etc.) you have to send a command that speciefies the VFO to which the following command(s) will be sent. 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.
To switch bands send the command bytes 07 B0. As Mark, N8MH, mentioned already: You don't need to switch anything manually.

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