so ive been messing with APRS for a few months now and finally got my Kenwood TM-D710 beaconing pretty consistently but the position that shows up on aprs.fi is like 3 miles from where i actually am. im using the internal GPS on the radio and the GPS lock looks solid, shows like 8 satellites. the symbol shows up in the right general area but its definitely not my house, its showing me in the middle of a field somewhere.

i double checked the NMEA settings and everything looks right to me, baud rate is 4800 which i think is correct. path is set to WIDE1-1,WIDE2-1 which is what everyone seems to recommend. not sure if maybe there's some offset in how the radio is interpreting the GPS data or what. anyone seen this before?

first thing id check is whether youre running the GPS antenna somewhere it might be getting a marginal signal even if it says 8 sats. sometimes the position accuracy is garbage even with a decent satellite count if the PDOP is bad. the D710 will tell you the GPS accuracy if you dig into the menus, cant remember exactly where off the top of my head.

also worth checking if you have any manual position stuff entered that might be overriding the GPS. ive seen people set a fixed beacon position for testing and then forget to clear it. the radio will happily transmit whatever you told it to even if the GPS is saying something different depending on how you have it configured.

3 miles off sounds like it could be a datum issue honestly. probably not but worth at least ruling out. more likely though is the manual position override thing the other guy mentioned, i did that exact thing when i first set mine up and spent an afternoon confused about why i was apparently operating from a parking lot two towns over.
