Ok. Actually, it was trivial. I recompiled soundmodem because I added a feature to use the GPIO on the USB sound chip as PTT. > Next, make sure your GPS can speak NMEA over a serial port.

Xastir chirped a few times, which seemed to be it sending a location packet[1]. Success! Incidentally, with gpsd the "View|GPS Status" menu option always tells me I have no satellites or that the GPS data is more than 30 seconds old. Does this menu option only support directly connected GPS receivers? Or should it work with gpsd-connected GPS? 73, Andrew [1] I am monitoring the sound card output. I am not yet in a position to connect to another receiving statio. _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
