Announcing a flight from Elsworth tomorrow - launching around lunchtime.
Primary: X1: 434.500MHz 700Hz shift 50baud 7N1 RTTY
Secondary: X0: 434.405MHz RTTY/LoRa
Listeners would very be appreciated.

Thanks all for tracking this flight. As you may have noticed, it landed in
a tree, in fact all 3 payloads (2 radio payloads and 1 camera payload)
landed at the top of separate trees, with the 'chute and balloon at the top
of yet more trees.
We couldn't reach any of them with a single telescopic pole, but
fortunately I had 2 poles with me so we built a long and very floppy pole
by putting one inside the other, and applying generous quantities of gaffer
tape to the join. Even that wasn't quite enough to reach the line (easiest
part to get to) but was enough to get to the camera payload. After a few
minutes of waving the beast around, we managed to snag the payload and
slowly pull it down. All 3 payloads, the chute and balloon remnants all
came down as I pulled.
