found this informative you tube vid, about how a few hams used S band dish antennas to listen to the diect
voice communications from the Apollo missions on the moon. As explained in the vid, the highly directional
nature of the 2.3ghz S band microwave signals proves,they had to be from the moon, instead of relayed
from earth orbit...there is a mistake in the video however..the narrator says the apollo communications were rebroadcast over shortwave via sattelites..this is not true..in fact they were done so live over the Voice of America short wave network...using the VOA's regular megawatt earthbound transmitters.
To conclude IMHO this fine video should give most HB's fits...
