In Sagan's Pale Blue Dot , in the Chapter "Darkness" (page 294 paperback edition) is a mention of 11 apparent non-repeating signals found by Project Meti. The odds were 99.5+% that they were located in the Milky Way, based on their distribution on the sky.
I know that SETI has detected a lot of non-repeating signals (especially the one from TYC 1220-91-1) and would like to know if they are also distributed such as to appear located in the Milky Way.

The real question here is: what was in these signals? If nothing , then I don't think that they were signals. If they were things like TV and Radar with no info or modulation then they would be repeating. So, all the more reason to capture and attempt to decode any true information embedded therein.

That's why I said "signals" instead of "transmissions". They were some kind of signal, natural or artificial. Since we don't do more than catch a one-off, they don't qualify as First Contact.
This is why I think a few of the best signal locations, like WOW! and TYC 1220-91-1, should be monitored continuously for at least several years straight, to see if there is a long repetition period.
This would likely be the case if these are Benford Beacons. For example, suppose we send a 30 second signal to each of the million closest stars, such that each star gets a signal once a year. The repetition time would give the receiving system the duration of our planet's year.
But instead we look at these sites for a couple hours a year, at irregular intervals.
