This, and similar impressive accomplishments, has prompted some

Perhaps a better question is: What is the bandwidth?
What sort of signal do I have to receive in order to claim contact? Is one
bit/blob of energy at the right time/frequency good enough, or do I have to
demodulate the signal and extract a few bits of data?
Marconi claimed credit for the first transatlantic communication by sending the
letter S in Morse code. That sounds like a fine standard - one byte of data.
It's statistically significant.
With regard to the restoration and use of a derelict radio telescope for amateur
radio, that's a fine example of amateurs putting themselves to a big task and
succeeding. I work on radio telescopes, so I know how big a task that is.
