Wow, those are unusual grid squares... that is, finding a grid square (CN69) that N7SFI [now WI7P] hasn't worked is rare indeed! I would be pleased just to get three grids. So for me, CO60 would be frosting the cake, but others may have other opinions. Thank you so much for going out there! -- KD6PAG (Networking Old-Timer, Satellite QRPer) P.S. I'll be in CM86 on Saturday afternoon (and possibly one pass on Sunday afternoon/early evening). KA9SCF, please try to work me there if you don't have it already, so i can return your favor in advance.

Re: RAFT is coming down! Grab telemetry
by Geoff Clark 29 May '07

Hi Bob, I'm at work but my antenna is beaming at the average max elevation points of all today's passes (basically South) and should be sending in the TLM via ZL2BAU. David, ZL3AI may also be monitoring/gating. 73 Geoff ZL3GA Christchurch, New Zealand RE66ho > > -----Original Message----- > > From: amsat-bb-bounces(a)amsat.org > > [mailto:amsat-bb-bounces@amsat.org]On Behalf Of Robert > > Bruninga Sent: Tuesday, May 29, 2007 7:03 PM > > To: amsat-bb(a)amsat.org > > Subject: [amsat-bb] Re: RAFT is coming down!

SO-50 jumped 5 kHz up in downlink frequency
by OZ1MY 29 May '07

29 May '07

Hi all, I listened yesterday to SO-50 and it appeared to be 5 kHz higher in frequency than normal on the downlink - approximately. Tested it right now and got it confirmed. Did anybody else hear it ? The pass had AOS at 1840 UTC here in Copenhagen. I have heard this before - but it is a long time ago. 73 OZ1MY Ib

Re: RAFT is coming down! Grab telemetry

RAFT is de-orbiting within the next 12 hours or so. It will arrive much earlier than any prediction based on Keplarian Elements because they are always too old. Best bet is to start 20 minutes early and point your beam towards AOS and where it will get about 10 deg above the horizon and wait. Then manually follow the short 3 minutes along the track... - Who will get the last telemetry? - How hot will it get before telemetry dies? We need worldwide operators collecting telemetry packets if they want to capture the last packet. See the live temperature plot on the RAFT-RE_ENTRY WEB PAGE... http://www.ew.usna.edu/~bruninga/craft/save-raft.html We particularly need data from the southern hemisphere where the passes are in the sun and will show the highest temps... Tune in 145.825 1200 baud AX.25 packet. And even with a small antenna, on the two overhead passes per day, you should get at least one telemetry packet. They are every 10 seconds.. Each one begins with a unique serial T#nnn and so we can merge different captures from different folks. Bob, WB4APR

ISS Spacewalk may be on VHF-2 Frequency early Thursday morning.
by andy thomas 29 May '07

29 May '07

I know that when the Russian suits are used for EVA from the ISS they use the VHF-2 FM frequency 130.165 and they can be heard from England. So stand by, Russia, India, Africa and Europe for an eavesdropping opportunity: Following from NASA: "Commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov are preparing for two spacewalks. The main objectives of the first Russian excursion on May 30 are to install orbital debris protection panels on the Zvezda service module, route cables associated with the Automated Transfer Vehicle navigation systems and replace experiments on the module's hull. .... Wednesday's spacewalk is scheduled to begin at 2:20 p.m. EDT (1820 UTC) and will last about six hours. NASA Television coverage of the spacewalk will begin at 1:30 p.m. (1730 UTC)" So if you check the new keps (orbital boost last Wednesday) I bet she will be orbiting over Russia from that time, so Eastern Europe, India and Africa will hear first and later that evening might be audible on VHF-2 130.165(Russian suits again)from the UK. Use your 2m beam and track the ISS. TIMES: 1820 +6h = 0020 utc. Heavens-above has ISS visible my QTH at 0038 utc 31 May. BTW you can get NASA TV on broadband internet nowadays. 73 es gud dx de andy G0SFJ ___________________________________________________________ Yahoo! Answers - Got a question?
