Thanks Jon for the update on the CP for 1500, which even I have had trouble keeping up with, since it has dragged on for so long!! It's also been a bit confusing for me. Anyway, my private opinion is that without an FM, I can't see how the original CP for 1500 could or would be able to make it financially. The one for Venice with the low power sounds fascinating to me, like a small-town community station from years gone by.
My memory is hazy, but when I lived in Anaheim and was an active AM band DXer in the IRCA club (Int'l Radio Club of America), I seem to recall that KROQ-1500 was in Spanish and used very lower power also, around 1980-1984. In fact, I seem to remember the station went dark sometime around or during 1984, but I was never able to determine the reason it went dark. The CP by Royce seemed to come out a couple of years later or by 1989 or so.
