A few things:

1. In SatPC32 under Radio Setup you do not need any of the serial port
settings like RTS, DTR etc. Don't check them.
2. Make sure radio and software have the same baudrate
3. Make sure all four addresses (Icom) are set to $7C. Use the upper arrow
keys to change and set both of the lower windows. Check the box "Addresses
OK" to set the upper window. All four addresses need to be $7C.
4. Store the setting and restart the software.
5. Make sure C+ (Cat Control) is enabled).
6. Go to CAT (Cat Tuning) and set the Interval for SSB/CW and FM/PKT to
zero and click "Store" for both and select "Continue".
7. Restart the software.


1.You installed the Silabs drivers for the Icom USB driver *BEFORE* you
connected the radio and turned it on.
2. You verified in Windows, System Properties, Device Manager that you have
2 com ports (CP210x...) and you use the lower one for SatPC32.

If all that is in place, let us know if and what works,

Stefan, VE4NSA
