These birds are worth \na considerable amount, even though they're not usable for their intended \npurpose. I would think a \"donation\" of the use of the bird to AMSAT, a \nnon-profit organization, would reap some substantial tax benefits, as \nwell as benefit emergency communications. The question is, who has the \ncontacts to advance such a proposal? Certainly not me :)\n\n73,\nKarl, WA5TMC\n\n\nAndythomas wrote:\n> Hi gang,\n>\n> I was reading an ESA press release about satellite radio experiments and\n> didn't realise its emphasis on re-using redundant broadcast tv satellites\n> until I read the bbc version of the story at:\n>\n> http://news.bbc.co.uk/1/hi/technology/6301359.stm\n>\n> which explains that when the broadcast geostationary saetllites lose fuel\n> for position control the tv guys lose interest in them, even though the\n> transponders work fine.\n>\n> Then I fell to wondering:\n>\n> whether we in the amateur satellite service could not use both the up and\n> down links on these redundant geostationary birds?\n>\n> I don't know the exaxct frequencies but there may be one out there that has\n> frequencies we share (or at least the uplink).
