Just for the "fun" of it I'd like to see an accurate link budget written up.  It is a little bit out of my comfort zone.  Maybe Domenico or one of you who has this knowledge could do it.  I may even learn something.

Are you sure about that, Dan?  I'm hardly an expert on EME, still 
looking to get there, but based on numbers I worked with some 
time ago, even 500mW from the Moon should be copyable with 
a good radio, with a yagi and possibly a  preamp.  This is not to 
say that a random HT would work, but I don't think we're talking 
of the classic EME-capabile station.
