so ive been banging my head against this for like three days now. running a TM-D710G in the shack connected to aprx on a raspberry pi, the radio hears plenty of traffic and i can see packets flying by in the log but my own station just doesnt show up on aprs.fi. digipeater hears me fine, i can see it rebroadcasting my packets in the log, but they never make it to the internet.

the igate that should be picking me up is only about 8 miles away and i can see it on the map so its definitely up. path is set to WIDE1-1,WIDE2-1 which should be totally standard. tried dropping to just WIDE1-1 and same result. ssid is -9 if that matters. starting to wonder if its a filter issue on the igate side or something with my callsign not being validated but i did the passcode thing when i set up aprx so i dunno.

anyone run into this or have ideas where to look next

check if the igate is running a range filter. some of them are set up to only igate packets from within a certain radius and if the operator set it tight you might just be getting dropped even though the digi heard you. you can test this by watching aprx's log carefully — if your packets are being heard by the digi and rebroadcast but nothing shows on aprs.fi after like 10 minutes then thats almost certainly a filter or the igate just isnt connected to the tier 2 servers properly.

also double check your aprx.conf, specifically the mycall line. had a buddy who had a trailing space in there and it caused all kinds of weirdness with the passcode validation even though it looked right on screen.

yeah the filter thing is probably it honestly. but also — have you tried just bypassing your local igate situation entirely and connecting aprx directly to rotate.aprs2.net and seeing if your beacon shows up that way? that would at least tell you if the problem is on your end or the igate's end. then you can narrow it down from there. i spent way too long chasing a hardware problem once when it turned out the igate two miles from me had been offline for a month and nobody noticed lol
