I'd contact the Arecibo people and get it scheduled as an experiment. Heck,
they radar-mapped the moon at 430 mhz.

I don't know of anyone who's done it with ATSC signals.

A TV DXer in Australia has DXd analog carriers via moonbounce.

What such a test could accomplish:
1. Find out if ASTC error correction can survive EME, enough that is to
get
a station ID.
2. Find out what 'emergency utility' such a communication system might
possess.
3. As a propagation experiment.
4. As a test of a radio astronomy network.

The signals do not appear to be strong enough to even deliver sync buzz,
let alone decodable data.  A larger antenna would help but with these
wide signals I doubt one would reach decodability.
