The TV signal from Parkes was relayed by the comsat station I was working at, OTC Moree. All three 24/7 video capable dishes used were around the 200 foot diameter size, anything you read to the contrary is just plain wrong. Btw, a movie was made of the Australian Parkes dish contribution....
I stand corrected on type of power supply used for Alsep. However I was correct in surmising there would not be enough power in time to run the transmitters and receivers, https://en.wikipedia.org/wiki/Apollo_Lunar_Surface_Experiments_PackageThe ALSEP system and instruments were controlled by commands from Earth. The stations ran from deployment until they were turned off on 30 September 1977 due primarily to budgetary considerations. Additionally, by 1977 the power packs could not run both the transmitter and any other instrument, and the ALSEP control room was needed for the attempt to reactivate Skylab. ALSEP systems are visible in several images taken by the Lunar Reconnaissance Orbiter during its orbits over Apollo landing sites.
That's a hell of a lot of plutonium power, and it was supposed to decay in power by less than 10% over a decade. Plutonium-238 has a half-life of 87.7 years. This was just 1977, less than 5 years after the last Apollo mission. So roughly 95% to 97% power (depending on which Apollo Mission) was suddenly not enough power to run anything? I call total bullshit. I bet that a Systems Nuclear Auxiliary Power generator placed on the Moon in 1970 would still have more than 70% of its original power capacity today, and I bet that would be more than enough to power the transmitter.
