There are 2 anomalies with Kimberlin's story, as I read it.

If the July, 1969 flight of Apollo 11 was the "last possible launch
window for a lunar mission in the 1960's", then how did Apollo 12 take
place between 11/14/1969 and 11/24/1969 ?

(2) ... as well as numerous mentions of "NASA color video and sound
we were all observing from the moon". While there was indeed
capability for color video from the Command Module [at that point, in
orbit around the moon tens of miles overhead], the transmissions from
the Apollo 11 Lunar Module on the surface of the moon were monochrome.

[TELECOM Digest Editor's Note: As I recall, what we saw on television
that night was entirely black and white. However, in the NASA archives
(reached via this report in our telecom archives) there are many color
photos of the same event; also you can see the certificate NASA awarded
Don Kimberlin for his part in the project. PAT]

May be instructive and useful ...

P.S. ---- I know you said "T1", but just as FYI

has some good info on various flavors [or should I say, flavours :-)] of
E1 R2 signalling, and the accompanying signalling bits if anyone is
