so ive been messing with APRS for a few months now and i cant figure out why my packets arent showing up on aprs.fi even though the local digi is definitely hearing me. i can see my callsign pop up in the raw log on the digi (its a KPC-3 Plus running as a fill-in i think) but nothing ever makes it to the internet side. my path is set to WIDE1-1,WIDE2-1 which i thought was pretty standard but maybe thats the issue.

running a TM-D710G into the radio port on my HT for the GPS feed, and i've got the baud rate set to 4800 which matches what the manual says. beacon rate is every 2 minutes. TX delay is 50ms. i dunno, everything looks right to me but clearly something isnt working right.

anyone run into this where the digi is picking you up but the igate just isnt forwarding it? is there a way to tell if the problem is on my end or the igates end?

yeah this is actually a pretty common thing and it usually comes down to the igate not having RF-to-internet enabled, or the digi and igate arent coordinated right. the digi hearing you doesnt mean much if the igate isn't close enough or properly configured to pass packets upstream to the APRS-IS servers.

check aprs.fi direct for your callsign but also try filtering by the raw packets tab - sometimes youre actually getting through but aprs.fi just isnt updating the map view right away. also look at findu.com, it sometimes shows stuff aprs.fi misses for whatever reason. if neither shows anything then the igate leg is definitely broken somewhere. you could also try messaging a nearby igate station directly from your radio and see if they get it, that'll tell you a lot about where the chain is breaking down.

your path looks fine honestly. WIDE1-1,WIDE2-1 is exactly what most people run around here. id bet its the igate and not you.

tx delay of 50ms might actually be too short depending on your radio - some rigs need more like 150-200ms for the TNC to fully key up before sending. i had a similar thing a while back and bumping that up fixed it, packets were getting clipped at the start and the digi couldnt decode them cleanly even if it was hearing carrier. worth trying before you go nuts chasing the igate config.
