For the Icom radios, an additional handshaking line must be connected to prevent the program from trying to write to the radio while it is transmitting. CAT control will not work unless this signal is wired up.
See the file SatpcISS.txt in the SatPC32 folder for details.

V12.8 is up and running. I learned the hard way that it is essential (as instructed) to copy all SatPC32 files into a new folder I named SatPC32_127. Then totally uninstall SatPC32 including removal of folder. Then, do a regedit removal of all vestiges of SatPC32 values before installing V12.8. I could then copy all my setup, keps etc from the SatPC32_127 folder to V12.8.
One thing noted - when running SatPC32ISS V12.8, the CAT feature is not working with my IC910H. The CAT works with the regular SatPC32 v12.8 program. Is this normal?
