The owner of the small tape has replied, he will digitize it in two weeks.
There was also a big reel, but that one is owned by someone else. The owner of the small reel will ask if he can borrow the big reel.
That is all on that for now.
I have found an other source of reels, this time Apollo 16.
Here is the message that was send to me:
"In 2013 I visited the 20 meter ground station in XXXXXXXX, Germany, now operated by the German branch of the AMSAT (Radio Amateur Satellite) group, of which I am a member. I was surprised to see an old RCA TR-70B quad VTR on display; in my college years I'd operated this same model as a summer broadcast engineering intern at WMPB-TV in Baltimore. Judging from the English and the crowfoot power outlets, it appeared to be an Australian or New Zealand model; they used PAL as did Germany.
I learned that during Apollo this site had recorded video directly from the moon; the tape on the machine was labeled Apollo 16. However, both it and the machine were in terrible shape and would obviously require a lot of TLC to make functional again. And I don't know if the tapes would be recoverable. I think I was told that additional tapes were in storage. If anybody ever wanted to investigate reading them, I'm sure they'd be happy to help."
I have send him a message back, and hopefully a restoration effort can be put into motion to play and digitize the tapes that recorded signals received from the moon.
I have left out links and Emails out of this post intentionally because I am afraid they will get spammed, and that it will put them off.
if you have any questions, I will try to answer them or relay them.
Cheers,
