Check your local air regs, you may not be allowed to launch a 30-footer without special permission. You probably CAN launch below some specified weight-limit though, which is usually enough for a GPS, APRS board, small 2m transmitter, camera, and batteries.

Can't help wondering if the "?????" is NOT a bad decode, but a bad GPS fix. The rest of the frame is quite well-formatted including the / and O. It looks like it still has Altitude (the A=) but the value looks dodgy compared with when it DOES have a fix.

Nick VA3NNW ... recently been studying APRS101.pdf and oh, my, what a mess, not so much a standard, looks more like a dumping ground of every new format anyone felt like inventing :-(

Do not underestimate the value of print statements for debugging.
