| Hello, again!
Looks like there will be a balloon launch from Latvia tomorrow morning (Friday, April 10). It will be done by Ventspils University College, I'm not involved with them, just passing the information I know, if anybody is able to help them with the tracking as it will be on a workday.
Expected burst altitude is around 25 km, so it should cover some part of northern Poland.
Launch time: 9:00-10:00 (local time), 6:00-7:00 UTC
Launch site: Ventspils Airport (KO07sj)
Callsign: IRBE-1 (Infra-Red Balloon Experiment-1)
434.276 MHz, USB
RTTY, 50 baud
425 Hz shift
ASCII 8 bits, no parity, 2 stop bits
Telemetry in standard UKHAS format.
Predicted flight trajectory, expected burst altitude around 25 km:

| If anybody is going to track this, the team reports having some issues with the GPS, they are delaying the launch and hoping to fix it till 10 UTC. |

| Dlaczego SP4MPH nic nie odbiera?
Coś jest nie tak z GPS, cały czas te same odczyty i 0 sat.

| Uh oh, they haven't properly set Ublox GPS into flight mode, so it has stopped reporting position and altitude above 12 km.
It's a 600g balloon with a slow ascent rate and looks like it will come down somewhere in Lithuania. Maybe. Eh.. |

| It is a few kHz below the nominal frequency, as reported on UKHAS IRC channel #highaltitude (Freenode network).
I'm not tracking today, can't confirm. |

| It's interesting, if GPS will start up again when they drop below the height of 12000 m?

It got fix now, and my bearing is 15 deg, so my measurements were right ;-)
1 degree below horizon and s/n 25..27dB, 523km. Not bad.

it started to drift left anf right with frequency. It it typical to balloon explosion.
EDIT: strength of signal is now quickly falling down (11:40 UTC)
EDIT2: 11:44 UTC - no signal.
