radiogooroo said:In the PPM world, you can't be counted as a simulcast unless you're 100% simulcast, but unless there's some local statute against it in NYC, I don't see why you couldn't do a 100% simulcast.
In the diary world, to be counted as a simulcast and eligible for Single Line Reporting, you also had to be 100% simulcast. Single line reporting was expanded about 8 years ago to include trimulcasts and beyond, too.
The FCC prohibited fulltime AMs from simulcasting on FMs effective the start of 1967; there were a number of waivers. I really don't know when it became OK to simulcast in the same market or, even, to do the kind of FM/FM or FM/FM/FM such as Big City did.
