APRS beacon showing up on aprs.fi but position is way off — TNC config issue?

so ive been messing with APRS on and off for a few months now and finally got my Kenwood TM-D710G set up with the built in TNC, beacon is going out every few minutes and i can see myself on aprs.fi which is cool but the position its reporting is like 3 miles northeast of where i actually am. the GPS is internal to the radio and i assumed it would just... work. lat/lon in the menu looks correct when i check it but something is obviously getting mangled between there and what ends up on the network.

anyone run into this before? im wondering if its a NMEA parsing thing or maybe i fat-fingered something in the symbol/position setup. also not totally sure if the path im using (WIDE2-2) is right for suburban area, i see some people argue about that constantly on here.

the WIDE2-2 thing is a whole rabbit hole but for suburban/urban you're actually better off with WIDE1-1,WIDE2-1 or even just WIDE2-1 depending on how dense the digipeater coverage is near you. WIDE2-2 isnt wrong exactly but you end up with a lot of redundant hops and it annoys some of the igates in high density areas. thats probably not your position problem though.

for the position being off — check if your radio is set to use the internal GPS or if theres a manual lat/lon still in there from when you first set it up. the D710 can be a little weird about which source it's actually using for the beacon payload. go into the APRS menu and look at the GPS unit setting, make sure its not just defaulting to whatever you typed in during initial config. also worth watching the raw packets on aprs.fi for your callsign to see exactly what coordinates are being transmitted, might make it obvious whats going on.

had almost the exact same issue with mine last year. turned out i had manually entered coordinates when i was first playing with it indoors and the radio was using those instead of the live GPS fix. took me embarassingly long to figure that out. just double check under the GPS menu that it actually says it has a fix and the coordinates there match what aprs.fi is showing — if they dont match then yeah its sending the static ones.
