Gerald from the unmannedspaceflight forum has the following idea:

When coding the upper potential with 1, and the lower potential with 0, with a more or less fixed clock rate, we get pairs 01 or 10, never 00 or 11. So such a pair, or transition, seems to code a bit .
So it should be fairly easy to convert the signal into a bit stream.
Then it only requires us to find the relevant documentation so that we can write a computer program.
Voice found on beginning of NASA tape
On satellite tape 'Sat-SNTAGO-120J827' a voice can be heard briefly at the beginning. The voice probably tells us the recording time. "The time is 11 5 AM"
The satellite is Upsilon 61, the recording date was Sept 7, 1961
I had to play the recordings backwards.
Here the fragment as an MP3 file.
