However, your arguments do carry merit. Terrestrial interference is becoming a huge problem. This is why a telescope array with dishes having more than 1000 miles of separation can overcome that issue.
Thanks for the correction RA. It's obvious I learned nothing during the brief period I loaned them my computer back in 1999. Sad to think I was one of their first participants.
You are being too hard on yourself. There are real probs with SETI, I have described a few of them. :-)
While I'm at it I think I'll rejoin the quest!
It's definitely a long shot. I wont kid you there. :-)
Here's a question I've wondered about on occasion: would an array on the dark side of the moon be shielded from terrestrial interference or would the 'ambience' still be so great that it wouldn't make much difference? In other words, if SETI were set up on the moon, could it search the entire spectrum, or at least much more of it?
