I searched back over the last few days and couldn't find a mention of
this project on here, so here goes...


I believe the project was by Dave M5AKA but it took a bit
of digging to find the callsign. The balloon made it to 39,994
metres and the Raspberry Pi sent SSTV images tot he ground.
They were tracking it, but it isn't entirely clear if APRS was
used. SSTV was just 10 mW on 434.650 MHz. There was also
a GoPro onboard. One of the pages actually mentioned RTTY
for the telemetry, so perhaps APRS wasn't involved.
