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.
