Peter,
My good freind and mentor, Dick - K6HIJ, set up a 3m comm dish in his yard and used a diode mixer driven with a HP freq. synthesizer to recover the carrier of one of the Apollos in orbit around the Moon in the early 1970's. You could hear the change in frequency due to Doppler and LOS when the Apollo went around the back side of the Moon and AOS about 20-minutes later.
We were both members of the sbms in southern california and Dick held a record terrestrial shot on 3300-MHz from around the late 60's or early 70's. Reading of that accomplishment in QST lead me to the sbms in 1970.
Of course we had access to a lot of mw gear at work.

Hi Clint and everyone,
look here for more:
http://history.nasa.gov/alsj/main.htmlYou find all the presskits from Apollo7 to 15 here: http://history.nasa.gov/alsj/main.html
But don't miss the videos and "Communications" stuff....
Imagine if amateurs at that time would have had the same S-Band receiving capabilities like today, thanks to AO-13 and AO-40... Would be nice listening to the moon :-)
Thanks and best wishes for 2009!! 73s Peter DB2OS
