The latest schedule has not been posted to the -BB yet, nor on the CAMSAT 
website.  However, the beacon will tell you whether the transponder is on, 
and in which mode (although I have observed 2 instances where the beacon 
indicated a mode different than what the satellite was actually operating 
in).  Just listen to the first part of the beacon transmission:  after 
sending the callsign BJ1SA, the beacon will transmit XW  twice.  The next 2 
CW groupings will tell you the mode:

AAA TTT  means beacon only.

TTT TAT  means that the linear transponder is on.

TTT TTA  means that the FM transponder is on.

The rest of the beacon consists of telemetry data, and ends with XW XW.

Hope this helps!

George, KA3HSW
