[amsat-bb] Unusual HUSKYSAT-1 Beacon Behavior ~ 18:12 UTC

[Bob]

Latest telemetry captures here in FN41 show power output at 16.1 mw, and PA
Current at 34.5 ma.  Sure hope it has been commanded into a low power state
(if that is possible).  That -10 dB power drop pretty much puts the signal
right into the noise floor.  Only copied 3 frames on a 46 degree pass at
17:40 UTC.  Two weeks ago it would have been 30+ frames

Not complaining, just observing.

73, Bob, WB4SON
