RT Systems software for the Icom IC-R30. When I try to download or upload to/from the radio, I get a message to make sure the cable is plugged in all the way. It is. I then get a message, "FT_SetLatencyTimer is not Valid!" I don't know what this is or how to fix it. FWIW, the ARC30 software sees the radio, but I don't like that software.
