Matthias, DD1US, would like to draw your attention to a collection of audio recordings, the ‘Sounds From Space‘ collection on his website at http://www.dd1us.de. This features a collection which has also a section dedicated to recordings of amateur radio satellite signals.

Please have a look at it. The idea is to give older radio amateurs the chance, to listen to signals of satellites which are already gone and the might have worked in the past, and to younger people interested in ham radio, to get them more excited in satellite communication.

In spite of the fact that the collection now has close to 1000 recordings he is still missing recordings from some amateur radio satellites.
If anyone of you would be willing to contribute recordings to these satellite he would highly appreciate it. He has and always will give full credit to the source of the recordings. Please have a look in your older tapes and recordings!
