This was the issue, thanks Jim Harman! Russ Perhaps aprs.fi is reporting in dd.mm (degrees.minutes) format vs decimal > degrees. That would be consistent with the numbers you are setting. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe,

Hi In general the N/S E/W part of the location should be pretty good between various reporting systems. Altitude … maybe not so much. These days, whatever GPS reports as “location” generally is considered to be correct. Anybody using a different set of numbers is expected to translate over

This has probably been mentioned before, but there is a significant discrepancy between APRS.FI locations for DMR hotspots for example, and what my Trimble receiver and Google Maps says when I use my address to lookup the coordinates. On APRS.FI my location has to be 45.15 N, -93.39 W for the
