More information: The intermittent communication problem exists even when no rig is attached. Can't reliably connect to send the message -Version and get a response. The USB connection on the side of the Nuvi works fine when connected to a computer for file exchange. Looks like there may be bad solder connections on the pin 1 - 8 side of the RS-232 interface chip in the Tracker2. I was using port B for the Nuvi and port A for the programming interface, I might swap them and see if anything changes.

The system seems to be working properly, I can send and receive messages via APRS, I see stations as waypoints on the map, etc. However I continue to get a message 'This accessory is not supported', and I have to cycle power to the Tracker2 to get the combination working again. Connectors all look good, rig is Yaesu FT-8800at low power (5W) and outside of the shack antenna, but still in the nearfield of the setup. Configuration or jumper setting?
