Hi Jim, Could you give me a bit more information on using WAAS? I disabled "gpsd" and then ran the command (gpsctl -x "PMTK301,2" /dev/ttyS1) which I thought would enable WAAS, but xgps shows that PRN51 is not in use. At least I think that PRN51 should show active with WAAS enabled. But I am totally clueless about this. In 2000 words or less, what am I missing? =) Sometimes I wonder if gpsd is meddling with things and causing me problems, in spite of their stated goal of non-interference.
