so ive been messing with this for like three days now and im going a little crazy. running a TM-D710G with the internal TNC, got it set up on 144.390, SSID is -9 which should be mobile. the radio shows it's transmitting the beacon every 2 minutes, i can even hear the burst on the audio, but when i go to aprs.fi and search my callsign theres nothing there. not even old packets.

i checked the path and it's set to WIDE1-1,WIDE2-1 which should be fine for my area. i know there are igates around because i can see other stations near me showing up fine on the map. at this point i dont know if its a TNC config thing or if maybe my audio levels are screwed up or what. the manual for this radio is kind of unhelpful on the finer points of this stuff.

anyone run into this before with the D710? or just APRS in general where the radio thinks its beaconing but nothing gets through?

first thing id check is your symbol table and symbol code — if those are misconfigured sometimes packets go out malformed and igates just drop them silently. also pull up a SDR or a second receiver and actually decode the packet yourself, something like direwolf in receive-only mode or even just a phone app like APRSDroid pointed at your audio. if the packet decodes correctly on your end then the problem is probably path or igate coverage, but if it doesnt decode then yeah its likely your audio drive level into the TNC or something in the config.

the D710 internal TNC is usually pretty solid but ive heard of people having issues when the internal volume setting gets nudged. theres a separate audio level setting for the TNC path thats not the same as the speaker volume, worth double checking that in the menu.

yeah what he said about decoding it yourself first is the right move. i wasted a week once thinking my igate setup was broken and it turned out my callsign had a typo in the config lol. literally one wrong character and aprs.fi just had no idea what to do with it. worth a sanity check on the most obvious stuff before going deep into audio levels and path configs.
