Check to see if they are both using the same DATUM. Google maps appears to use WGS-84. Maybe your T-Bolt restarted with something else though it’s default config is WGS-84. I don’t see a command line option to set datum with Lady Heather. If you have a serial link you can set/report with 0x8E,0x8F packets according to the manual > What setting do I have wrong in the Thunderbolt?

Be an interesting experiment to check that. > > > > > Demian Martin > > San Leandro, CA 94577 > > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there.
