wmtm am 1300 105.1 translator

How does wmtm fm 105.1 translator transmitt different programming than the am 1300 . i thought both stations had to air the same programming at all times.
 
There is one important exception to the translator rule, and integral to why the FCC decided to allow AM stations to have FM translators. If the station is a daytimer, the FM station can continue to air programming even though the AM station is turned off for the day (doesn't apply to WMTM). The FM Translator also has to be inside the contour of the daytime AM signal, but is not limited by the AM nightime contour.

This question though opens up a lot of "cans of worms" that I've been seeing as I review radio stations.

If the AM station is not transmitting in stereo, can the FM station be in stereo?

Can an FM translator have HD2/HD3 channels unrelated to the AM station?

Is there anything wrong if the FM station is actually the source and is actually feeding the signal to the AM transmitter?

I'm also seeing a lot of these situations "rebranding" their station using the FM. If I have Wxxx-AM with translator W2xxZZ, and my station IDs itself as "Wxxx-FM" when no such station exists, am I over the line? (or is the legal ID at the top of the hour all that matters?)

Yes.

Undetermined as yet. Nobody's tried. My hunch is that the Audio Division staff wouldn't allow this, as it would amount to "program origination" separate from the parent station of the translator.

As long as the AM signal is properly ID'd at the top of each hour, and as long as the translator does either a proper aural ID 3 times a day or a Morse Code FSK ID, the FCC doesn't care what the branding is the rest of the time.

There's no rule that explicitly forbids feeding the AM transmitter from the FM "translator" signal; whether an FCC inspector would see it that way is another matter.

**I believe** I've heard this done in West Tennessee. Can't remember which station. (WTPR-710?)

What I heard was a Morse ID for an FM translator, heard while tuning the *AM* dial. The licensee of the translator matched those of an AM station on the same frequency & in the same town.

What I *think* I was hearing, was the AM station relaying the translator complete with the translator ID. In theory FM translator Morse IDs are supposed to be not heard on a regular radio but it doesn't seem to take much interference to the FM signal to result in an audible heterodyne.
