Guys,
The apogee post burn contact was nominal for command/telemetry
The station power was increased from 277 watts to 370 watts to avoid
telemetry drop outs during the contact
@1628 ebno=19.67 - 20.94 db (2ksps)
agc signal strength= -121.584
@1649 ebno=19.73 - 20.72 db (2ksps)
agc signal strength= -119.902 with power increase
VC0=104/22
