Arrissat-1 UK Status Report.
by GW1FKY＠aol.com 29 Dec '11

29 Dec '11

Hi all, It may not be significant as I note from Roland that it was OK, however over here in Wales ( UK ) the pass today ( Thursday 29th Dec. at 1345 hrs) it did not sound as healthy on the downlink as I normally receive the satellite. Did hear my downlink much weaker and also heard 2E0SQL also calling CQ - Peter also heard you yesterday you were much stronger but did not get back to you as my antenna was doing a 180 degree turn. Will monitor the next pass and try to get an update on the status. Ken Eaton GW1FKY By the way, I note thankfully that all went well for the commercial launch of the Soyuz ( Fregat )and its payload on Wednesday 28th December.

FUNcube at Science Education Conference
by Trevor . 29 Dec '11

29 Dec '11

AMSAT-UK will be explaining the potential of the FUNcube satellite as a teaching tool at the Association of Science Education (ASE) Conference Jan 5-7, 2012. The ASE exists to provide support and ideas for school science teachers in the UK. AMSAT-UK will be having a small stand in the marquee (number AS28). The event takes place at the University of Liverpool. Admission to the exhibition is free, but to avoid any queuing, you may wish to preregister on the ASE website.

Re: ARISSat : only a few more days !

Out of curiosity, what method is used to keep the International Space Station from burning up? I know that periodic boosts are done to raise the orbit. Is that done with rocket engines built into the space station? If so, it seems that storage and eventual reloading of the fuel would be difficult and high-risk. Or is the ISS boosted using the engines of a docked vehicle? That seems like it would have its own set of complications. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik

ARISSat-1
by Carl Rimmer W8KRF 28 Dec '11

I wanted to let W6IHG that I did hear him through ARISSat-1 during my 1817 UTC pass. I have an audio recording of that pass. I believe I also heard WB2OQQ. There was also a station sending SSTV through the transponder but the station was not using Doppler. He went right out of the bandpass. I tried to follow but could not. I noticed that even though ARISSat-1 was in full sunlight, it went into Low Power mode. I was able to get a pretty decent SSTV copy during that pass, also. I am trying to determine what I am going to do when it terminates. It has taken up a good portion of my operating since August 4th. HI HI. There is another pass coming up in 5 mins (1951UTC). It will be a 13 degree pass so that should be pretty decent also. 73, -- *Carl W8KRF*

CRAIG W1MSG>> ... Another good pass on the East Coast USA in FN42 ... Downloaded two images and a really good long recording at 1822 UTC 59 degree elevation ... Craig - I have no idea how old you are chronologically. But I am in my mid-50s, and I STILL get excited with these reports ... Have you posted your images anywhere??? Clint K6LCS

Shut Down of VE3FFR PCSAT Beacon

For All Concerned Doug has shut down his PCSat beacon, see below Cheers & 73 Chip, VA3KGB ---------------------------------------- From: Douglas Richards <ve3ffr(a)cogeco.ca> Sent: Tuesday, December 27, 2011 10:08 PM To: va3kgb(a)rac.ca Subject: Re: Shut Down your PCSAT Beacon Please from Bob, WB4APR Chip If you could pass on to others.

His email is not listed with QRZ and I need to ask him to shut down his PCSAT beacon. This would reduce the load on PCSAT so that maybe I can get a command in to get control and maybe make a recovery. Next recovery effort will be dawn passes on Wed 28 Dec 2011. PCSAT is almost responding. I only need to get one exchange of packets successfully to do a recovery. We need everyone to turn off all transmitters and reserve PCSAT power so we can complete the command/ack sequence. You may continue to work the ISS, but ONLY if it is in view and is operating. Otherwise, please, no transmissions on 145.825. No unattended beacons... Adding also to the 145.825 channel QRM is UO-11 that appears to also have come back to life. Thanks, Bob, WB4APR -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I got my telemetry decode working just in time to enter the contest! Just out of curiosity, what is with the image appearing in the waterfall diagram? I've seen some 'green haze' like that in the transponder band when I receive it, but never anything discernible within it (nothing particularly audile either). If that is real, someone must be using up the whole transponder spectrum to send that odd picture! Thanks, Burns, W2BFJ

AO-7

I had a nice Mode A QSO with Brent, VA5MS, on the 1407-1427 pass this morning. Also heard KC9ELU but the bird was a bit far to the west for him. AO-7 will be in Mode A for most of SKN, so get those 10-meter antennas ready! CU then, Ray W2RS
