Each telemetry channel encodes a 3-character value.  "TTT" represents a 
telemetry value of 000, which would be normal for certain circumstances... 
when the Channel 2 telemetry value is 000, it indicates that only the beacon 
is operating (most of the time, for now).  When the transponders are not 
operating, it is normal for the telemetry channels associated with them (7 - 
13) to read 000.  The telemetry format can be found here:


Hope this helps!
