AO-27 computer has crashed. At the VT ground station (with KJ4QLP operating) we have seen MBL (microbootloader) control interaction between the spacecraft and the ground (MBLCTL packets). This means the command station(s) are interacting with a crashed spacecraft computer.
I do not have ANY inside information. I am reporting only on what I can see with my own packet decoder....

Subject: [amsat-bb] AO-27 possible failure
AO-27 sent data after the repeater mode expired on the 1835utc pass, 5 October. 50 seconds into the data, the "mark/space" toggling stopped and a "mark" only tone was heard. That tone was heard for 4-1/2 minutes until the signal was lost when the bird went over the horizon. A recording of the entire pass is on my website: http://www.papays.com/sat/general.html
AO-27 was not heard in EN91 on the scheduled 2015utc pass. I think my receiver is working fine but maybe it wasn't. Let's hope it can be recovered. An email was sent to N3UC and a message was left on his home phone.
Any reports from other locations? 73, John K8YSE
