Update #4 8:00am AEST 15 May 2014

Looks like the balloon decided it didn’t want to stay in NZ for too long.
It re-launched itself this morning, before NZ hams (and customs) could get to it

A big thanks for ZL hams who all geared up to search for the balloon, even with planes!

That was 24H of rest!

PS-6 was a last minute release on Thursday night 8/5 . It had THOR16 and RSID for auto tuning, in addition to APRS.

APRS callsign was VK3YT-11.

The GPS stopped working shortly after launch but APRS was working until the morning.
Last known location was near Moe:

Battery life of the payload should last at least 180H, so we might hear from PS-6 again!
