[SixClub] Question

[Christopher Boone]

Yeah but higher in freq (2Ghz or higher) where the antenna gain is MUCH 
larger...I'm sure it was FM because of the easier power budgets vs AM...
When the astronauts were on the moon, they talked through the LEM back 
to earth; not straight from their suits....and the LEM just had to talk 
to probably a 60ft or larger dish...at 2 Ghz, a 10ft dish has 30db or so 
of gain...I cannot even begin to imagine the gain at 60ft!

But some folks even heard the command module in orbit around the moon on 
its downlink freq with no problem using small dishes and homebrew 
rcvrs...I recall an article in 1970s QST describing how one group did it..
