by Ed Long 29 Jan '07

Everyone, I have received some offers of help to translate an article from German that I mentioned last week. Thank you very much for your response. I'm covered at the moment and hope to have the first part of the article in the next Journal (it's a long article and will be in several parts). Thanks again and 73, Ed Long WA4SWJ Editor, The AMSAT Journal

Re: Redundant geostationary birds
by David Barber 29 Jan '07

Following the recent discussion on using redundant geostat satellites I thought some might be interested in the following information. These are typical of systems in use for local news gathering (LNG) etc. http://www.sislink.co.uk/newsite/html/equipment_upod.htm The link below takes you to the system spec. Note the EIRP. http://www.sislink.co.uk/newsite/downloads/4343_Corp.%20Broch%20spec.pdf

AO-7.
by John Hackett 29 Jan '07

29 Jan '07

Hi All, I wonder if 5469 km is a distance record for a QSO on AO-7. Anybody managed anything further?. Just worked Dan AJ9K (for the second time) in Verona Wisconsin from Frei Island Norway. I also worked Igor UA9CS (The Urals) on the same pass so the coverage is outstanding for a LEO. 73 John. <la2qaa(a)amsat.org>

Redundant geostaionary birds?
by Andythomas 29 Jan '07

29 Jan '07

Hi gang, I was reading an ESA press release about satellite radio experiments and didn't realise its emphasis on re-using redundant broadcast tv satellites until I read the bbc version of the story at: http://news.bbc.co.uk/1/hi/technology/6301359.stm which explains that when the broadcast geostationary saetllites lose fuel for position control the tv guys lose interest in them, even though the transponders work fine. Then I fell to wondering: whether we in the amateur satellite service could not use both the up and down links on these redundant geostationary birds? I don't know the exaxct frequencies but there may be one out there that has frequencies we share (or at least the uplink). After all we have years of experience of chasing staellites which are not exactly where they should be in the sky and so the "wandering geostationary" satellite shouldn't be a worry. I think each transponder channel is 27 MHz wide?? I remember vaguely that there was a "pipe" on one of the birds from the UK to the USA which was used in amateur service about 15 years ago now (but I don' t remember very much else). If we could take over one channel on the transponder then immediately we would start looking at uplink equations, multiplex etc. and what about a mobile aprs service?! 90% of the world will tell you why it can't be done. Who can show how it can be done? 73 de andy G0SFJ

Pehuensat-1 heard in UK
by john heath 28 Jan '07

28 Jan '07

Hi, Sunday 28th - Just copied the satellite on the 22:35 pass in range of my QTH, IO92IO. Voice heard but too weak to copy. Bursts of packet data heard but did not decode with AGW Packet Engine. Good to hear this one after several days of listening. 73 John G7HIA

N2JDQ Station Update
by sraas＠optonline.net 28 Jan '07

28 Jan '07

Well the time has finally arrived and the weather was perfect, I now have my 2 & 435 antennas outside, mounted, quad pod mounted, cables ran.. ect . Just in time for a cup of coffee and a fo-29 pass. For the 1st time I was able to find my ssb on the downlink.. took me a while to find it.. and by that time I only cq'd a few times with no replys. I will be on the next pass.. I just have to figure out how to store the doppler diff.. I hit a button and it threw me way outa whack.. took me another minute to find my downlink again. Im sure with some practice I'll figure it out. Thank you to every one whom answered my questions... with out your help I would have never been able to do this. Now its time for some operating... cu on the birds! -Steve Raas N2JDQ FN20vg AMSAT 36396
