AO-7 UHF Beacon Activates RTTY Telemetry [AMSAT]
March 15, 2009 by kb3ljm.
The AO-7 UHF Beacon at 435.100 MHz has been reported as becoming operational. Satellite telemetry in RTTY format is being copied. The AO-7 70-cm beacon was monitored with very strong signals during February 28 passes and also since then. Some reported the beacon initially sounded as if it was in a two-state mode that sounded a bit like RTTY in idle. Successful RTTY decodes have been accomplished using “reverse, 45, 85″ parameters.
AO-7 Command Operator, Mike, N1JEZ says, “This is a pretty significant development. Every time I’ve tried to activate the RTTY system, all I would get is a solid carrier then the bird has reset indicating a lack of power.”
[ANS thanks Mike, N1JEZ for the above information]
