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

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.
