Echo First Communication Events
Plans call for Command Stations to begin working Echo with the morning passes over the US on 29 June. The first communication attempt with Echo will be on the pass over the eastern US, at approximately 1452 UTC, continuing with the next two passes over the US as well. The transmitter on Echo will not be turned on for a complete orbit until it is established that the bird is operating normally and that the power system is working properly. The transmitter will be shut off before the end of the pass
window over the US. Transmission may also be intermittent over the US as we work with the Satellite. The hope is to leave the TX0 transmitter on for complete orbits starting as early as 0200 UTC on 30 June.
The callsigns for Echo s Pacsat Broadcast Protocol Digital system are:
Broadcast: PCAB-11
BBS: PCAB-12
