Sure, that would be easy. It would also be easy to do it from your PC to avoid having to acquire and program the Arduino. I have a "GPS simulator" script that I wrote for D-RATS that simulates an NMEA stream over the socket so I can test tracking moving stations. It would be trivial to dump that to the serial port instead of a socket, which would cause the 2820 to think it had a (very boring) GPS connected to it. -- Dan Smith dsmith#danplanet.com, s/#/@/ www.danplanet.com KK7DS
