Why does SETI only run at 1.42 GHZ

Great Debates

SETI@home runs it’s program at 1.42 why is this the only frequency they run at, and has it not already been mapped?

I run SETI and think it is worth wild project but that was one of my main questions for it, I have read on the site why they say but I was under the impression that that had already been mapped.

Here is the site for you all :slight_smile: Thanks

It’s the hydrogen band. It seems to be the most logical place to look - hydrogen is the most abundant element in the universe.
