Icom CI-V programming
by Mike Diehl 02 Jan '19

02 Jan '19

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. 73, Mike Diehl W8LID/VE6LID

Arrow antennas
by Ray Soifer 02 Jan '19

Doug, The problem, as I see it, is that 2m and 70cm are harmonically related. If the two Yagis were in the same plane, there would be more interaction between them. Placing them 90 degrees apart minimizes such interaction. 73 Ray W2RS
