ISS Packet
by Kevin Deane 28 May '11

28 May '11

Got through this morning on the ISS using APRS. What frequencies are good for contacting the crew? I have heard of several differentones and seeing how it is always a pretty short pass...Or small footprint rather. I dont know just would like to try the right one. Thanks Kevin KF7MYK

Background: Was reading Endeavour to depart tomorrow from ISS, and on the issfanclub site was an overhead pass. Action: Began to call CQ and heard squelch opening until Mike Fincke called me back! We spoke for a minute and he even spoke spanish to me. So check on next pass. Later: Took a webcam video which will edit and post later on YouTube, will advise later. Cheers, Angel Santana - WP3GW

AO-51 now off
by Andrew Glasbrenner 27 May '11

27 May '11

Well, she crashed again. This time we restarted, and then killed the transmitter before AOS. In an hour we'll know if it makes it through with the transmitter off. If so, we'll start reloading code in the AM. Thanks to those who sent telemetry and reports. For now you can take a break, and we'll let you know when to listen again. 73, Drew KO4MA

***AO-51 reports needed*** 27 May 2011
by Mark L. Hammond 27 May '11

27 May '11

Hello AO-51 users, This afternoon 27 May 2011 AO-51 stayed ON for a full orbit. This caught both me and Drew KO4MA quite by surprise. It is completely unexpected. Had both of us not been there, we wouldn't have believed it.... KO4MA put it into repeater mode around 2000utc. When it came back over around 2145utc it was still up and in repeater mode!! We changed to digital mode to collect some telemetry and have left it in digital mode. **WE NEED REPORTS** in case it remains on next orbit (neither of us get another pass until tomorrow). You can listen on 435.150 MHz for the digital signal. IF you have 9600 baud packet and TLMEcho, you might be able to grab some telemetry that will be useful for us. Stay tuned! This might be a fluke, or it might be a good sign... Please send your email reports to the list and directly to us using our callsigns AT AMSAT.org. 73, Mark L. Hammond [N8MH]

FT847 satpc32 help needed
by Jeremy Bomkamp 27 May '11

27 May '11

If anyone has a modified doppler.sqf file for the Ft847, I would appreciate it if it could be posted or emailed to me. It is hard trying to dial in my downlink, while transmitting and holding an arrow antenna. 73

We switched it to 9k6 digital to try to figure out what happened. 9k6 sounds an awful lot like white noise. My gut reaction is the reversed cell failed again, this time to a dead short, and the remaining cells were enough to keep it running through eclipse. We also saw a 10 degree C drop in battery temperature between the first and second pass, indicating some sort of big change. At this point we are going to observe for a bit to firm up our hypothesis, then we will try to load the software, get some WOD, and get the transmitters shutting off during eclipse. Observations right now from when the satellite goes into eclipse would be -very- helpful. Exciting times, but I'm trying to guard my optimism. 73, Drew KO4MA -----Original Message----- >From: Kevin Deane <summit496(a)live.com> >Sent: May 27, 2011 6:13 PM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] AO-51 > > > >Was there people on that pass?

Was there people on that pass? It was pretty low for me, I was getting a signal on the down, but no people, I tried a couple times, I am pretty sure it was the bird because the signal faded away as usual. Anyway my friend KF1BUZ is heading to DN00 Black Rock Desert as I write this. I do not have that grid, just thought if anyone needed it that you might listen for him. Hope to catch some of you this weekend, thanks again to all who make it possible! Kevin KF7MYK

AO51 ON!
by PY5LF 27 May '11

27 May '11

What a good surprise now 21:30 UTC when I heard AO51 in very low pass for me , but with good signal . It means that the sat do not crash the software during the eclipse , I guess. 73 PY5LF LUCIANO FABRICIO CURITIBA-PR-BRAZIL GG54JM <http://www.qrz.com/db/py5lf> http://www.qrz.com/db/py5lf <http://www.falautomation.com.br/> www.falautomation.com.br

SO-50 and other Lamentations
by Giacobbe Lauser 27 May '11

27 May '11

So, I ran the passes yesterday and got updates on all the current sats so I could get back into things after an absence, and I was quite surprised... Am I to understand that the only active FM satellites now are AO-27 and SO-50? HO-68 bit the dust. AO-51 is in the crapper for a while. SO-67 is mostly off over the USA. ARISS is rarely on. What's the scoop? - Jake, KK6L

Has been on most afternoons 145.880 up and 435.150 down. West coast stations might more often hear it on the eastern passes. >SO-67 is mostly off over the USA. First week of the month is for NA and SA. I'll be writing the schedule tonight. > >ARISS is rarely on. If on, usually in digipeater. > >What's the scoop? > We need more satellites of all flavors. Support the program of your choice, Fox, P3E, Kiwisat, FunCube, or all of the above! Welcome back, Drew KO4MA
