[amsat-bb] Re: AO-7 tonight - would like to receive

I have tried to hear the mode A and B beacon a few times over the last few 
weeks, and did not hear anything.  I noticed the same thing during the last 
non-eclipse period earlier this year as well.  The mode-B beacon seems to be 
easy copy when there's eclipses, leaving me to wonder if maybe the 
beacon/telemetry system only works for so long, or maybe it gets turned-off 
by some means.  I have never heard the mode-A beacon.  I once heard the 
mode-B beacon sending  repetitive "hihi" at extremely fast speed(60-plus 
WPM!), although I can't remember if it was during a non-eclipse period or 
not.  It normally sends sequences of three-by-three telemtry data beginning 
with "hihi", just like FO-29 does now.

I also wonder if any command station have tried any commands on AO-7 in 
recent times, to see if it responds to commands such as beacon on/off, 
telemetry beacon speed, or transponder-mode switch?
