[amsat-bb] AO7-A
Hello Fellow satellite users; Is anyone operating AO7-a? A few of us diehard satellite users are working AO7-A, the satellite is generally pretty empty, normally I am just listening to my own signal on the down-link. Mode A works just as well as Mode B does, you can use your HF beam as a receiving antenna if need be to copy the down-link. From EM55aj I have worked 2E1EUB in the U.K., I have worked Hector, CO6CBF, in Cuba and I have worked HK3MKE in Columbia, the satellite works fine there are just not many stations there. If anyone wants to give AO7-A a try drop me an email, I am retired and have the time to operate and I don't mind the early morning or late in the evening passes, I have a SKYPE account that I can be reached on as well: K4FEG_EM55. We are running out of options here on the satellites and I am not an SWL so I don't plan on sitting around just waiting for a satellite miracle, If it's up there and it will receive my transmissions, I am going to try and operate that satellite! Remember: Just work them birds until the antennas burn off during re-entry!! That's my story and I am sticking to it! 73, Frank; K4FEG EM55aj ___ Sent via AMSAT-BB@amsat.org.

I see KEPS for six new objects have been added to the end of this list: http://celestrak.com/NORAD/elements/tle-new.txt I presume these are the CubeSats deployed on October 4. The Autumn (Fall) edition of the AMSAT-UK newsletter OSCAR News is now at the printers and should be posted to members soon.

Greetings...there are engine problems and there are engine problems (grin). shutting one down is one thing but one coming apart is another thing. This is the first time I am aware of a vehicle going up the hill has had an engine come apart including mostly likely losing the engine nozzle...and the vehicle just keep on going. if you are on facebook come to my page, I have some stills posted...

[amsat-bb] Re: Falcon 9 Engine Anomaly
I noticed two things that I found interesting. The amount of flames that were outside the engine nozzles. When i see flames like that it brings back memories of another flame where it should not have been. And the result of that flame. The other thing I was totally thrown back by the temp of the nozzle on the second stage! It was white hot all the time during burn. Like WOW!

[amsat-bb] Re: AO-27 possible failure
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 Bob N4HY On Sat, Oct 6, 2012 at 5:27 PM, Raydel Abreu Espinet (CM2ESP) cl2...@frcuba.co.cu wrote: On pass of Oct. 6th at 19:45Z didn't receive any signal.
