Doug, W8NFT, sent me this booklet and copies of the recordings that came with it. Below you will find links to the booklet itself and the two mp3 files. Note that the signals were captured using an HRO receiver. Side A is a "re-creation" of the launch ("spine tingling in its realism!!!!") Side B is an actual recording of the sat's iconic beeping.
