so ive been trying to get my mobile APRS setup working for about two weeks now and im losing my mind a little. running a TM-D710G in the truck with the internal TNC, beacon interval set to 2 minutes, path is WIDE1-1,WIDE2-1 which i thought was pretty standard. i can hear other stations digipeating just fine on 144.390 and my radio is definitely transmitting because i can see the TX light flashing on the right interval.

but i go to aprs.fi and search my callsign and nothing. not even an old packet from when i was testing last week. my buddy K4something drove past an igate that he said definitely works because his icon shows up fine. so im wondering if theres something wrong with my path settings or maybe the symbol i picked is causing issues somehow? i dont think symbols matter for digipeating but i honestly dont know

also worth mentioning im using the APRS feature through the radio's built in GPS, not an external one, and the coordinates look right on the display so that part seems fine

path looks fine for most areas, WIDE1-1,WIDE2-1 is what most people run. first thing id check is whether your audio levels are set right — the TM-D710G has a separate data band setting and if the deviation is off the packets might be transmitting but just getting rejected by igates or not decoded properly. there's a setting in the menu somewhere for the packet audio level, i forget the exact menu number but it's in the TNC section.

also double check that you have the correct band selected as the TNC band. the 710 can do crossband stuff and sometimes people accidentally have the TNC bound to band A when they think its band B or whatever. had that exact problem myself when i first set mine up, drove around for an hour before i figured it out

check aprsdirect.com too, sometimes aprs.fi has caching weirdness or just doesnt show stuff right away especially if you havent beaconed in a while and the entry aged out. if you dont see it on multiple sites then yeah something else is going on. also what symbol are you using out of curiosity — youre right that it shouldnt matter for actual digipeating/igating but im just curious
