[amsat-bb] SatPC32 actinh wierd

Thanks for the prompt reply Erich. I'm currently at my winter home in 
Florida, all my sat equipment is at my summer home in NJ, so I didn't have 
it in front of me to help Scotty try and sort out the USB drivers. That 
being said, I know the 9100 comport is virtual, but I wasn't sure about the 
LVB, but that still doesn't explain to me why I would lose the LVB 
calibration if I turn on the devices in an incorrect order. I usually save 
the pass by looking out the window at the antennas and quickly coming up 
with a fudge factor to enter into the rotor offsets in SatPC32 , then do the 
re-calibration afterwards.  I would think I would just get a comport 
error,that would be fixable by simply turning off, then on the devices in 
the correct order. Any ideas on this?

Also, while discussing this, I think back to when I had this problem. I 
remember SatPC32 taking quite awhile to recover from my operational blunder. 
I routinely use the 9100, along with my K3 with DXLab, the DXLab rig control 
program Commander doesn't have this problem. If the 9100 is off when I try 
and select it with Commander it just sits there till I turn on the 9100 and 
then all is well. I don't have to reboot Commander to recover from the 
missing comport error. I will be back in NJ for the summer in a few days and 
will be able to test this if you want me to try anything...

Hi Jeff,
I suppose you steer the IC-9100 via one of  it's two USB ports for CAT
control. Then it is necessary to switch on the IC-9100 before you start
SatPC32. The built-in USB-to-Serial adapter of the IC-9100 is fed by the
radio. Therefore the generated (virtual) COM port is not available if
the radio is off. When SatPC32 starts it checks whether the selected COM
ports for CAT and rotor control are available and sends the error
message if not.

You can only avoid this if you connect the radio via a "CAT cable"
between the PC and the radios CI-V connector because the built-in
USB-to-Serial adapter of the CAT cabel is fed by the PC.

The LVB Tracker uses also a built-in USB-to-Serial adapter. So, it's
generated virtual COM port is also only available if the LVB Tracker is on.
