Dear HAB Enthusiasts,

The Physikalische Technische Bundesanstalt (PTB) <http://www.ptb.de>
announced to launch two HABs during this week.

Background for the launch are dosimetric experiments in altitudes of up to
30km.

On this opportunity DL0PTB will be able to add Amateur Radio payloads.

The launch location the the Meteorologic Observatory in Lindenberg
<http://www.dwd.de/mol>, near Berlin. (JO72BF)

The expected flight time has been estimated to be 3 hours.

The following amateur radio systems will be on-board:
APRS at 144,800 MHz (Callsign: DL0PTB-11)
Speech output at 145,200 MHz (100mW output Power)
SSTV (Scottie 1) at 145,200 MHz
Crossbandrepeater 70cm -> 2m @ 100mW output power
--> Input Freq: 433,920 MHz
--> Output Freq: 145,400 MHz

The repeater can be opened by sending a 1750Hz tone, it does not provide
any squelch, so if opened without traffic white noise will be transmitted
it shuts down after 60min inactivity but can be re-triggered through
sending the tone.
