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

[Mark L. Hammond]

HI Bob, sounds like they (UW students) commanded it into SAFE mode.  Watch
the telemetry, it'll tell you...TX off, then TX ON to send a few frames,
then OFF a couple minutes....repeat.   Sounds like a Fox-family member
indeed!
