the special program version for in-band operation over the ISS -
SatPC32ISS - unfortunately doesn't support the FT-817 (see SatPC32ISS
menu "?", "SatPC32ISS").
So, try the "normal" SatPC32. Make sure that the FT-817 display shows VFOa.
If it displays VFOb click button "A" below the display to change the VFOs.
Then select the ISS. The display should now show the RX frequency of the
first entry for the ISS in Doppler.SQF. During TX the uplink frequency
should be displayed.
I have tested that with my FT-817 and it seems to work.
CAT Baudrate 38400,
CAT delay 110,
all options in menu "Radio Setup" unchecked.
the radio switched to Split mode.
