Hi All,

Just a couple of  updates!

PW-SAT will have 5 possible operating modes as shown below – we should 
expect the FM/DBS transponder (mode 5) to only be operational after the 
science mission has been completed - however the 1k2 BPSK transmissions will 
provide some good "in orbit" demonstration signals for AMSAT-UKs's upcoming 
FUNcube mission later this year:

DOWN-LINK: 145.900 MHz  Available Modes:
1. Receive only mode. DOWN-LINK: none
2. Beacon CW mode. DOWN-LINK: BEACON CW  12 WPM
3. Beacon BPSK mode. DOWN-LINK: BEACON BPSK  1200 bps AX25 (1 frame on 20 
sec)
4. Control communication mode. UP-LINK: Commands DOWN-LINK: BPSK  1200 bps 
AX25
5. Repeater mode (aka "AO16" mode). UP-LINK: 435.020 MHz FM   Voice 
DOWN-LINK: 145.900 MHz DSB  Voice (repeated from up-link)

During LEOP,  the "launch and early operations phase", tomorrow, listeners 
are encouraged to gather at the IRC "cubesat" channel to exchange all the 
latest available information . You do not need to download a special IRC 
client to achieve this - simply point any browser at 
http://webchat.freenode.net and join the #cubesat channel.
