A translator generally has to exist within the station’s existing coverage to “fill in” any coverage gaps (i.e., blocked reception by mountains, river valleys, etc.). This concept has been extended to include the re-broadcast of HD sub-channels and AM signals using the same logic: the translator fills in coverage that within an existing coverage area, thereby making it easier to listen to the origin station.
A translator can only exist outside of a station’s existing coverage area if it belongs to a non-profit broadcaster. Enter religious broadcasting. And some creative public radio organizations (i.e., Minnesota Public Radio).
In either case, the audio source of a translator can be anything: satellite feed, internet feed, microwave transmission, etc.. It is very rare these days for an audio source to literally re-broadcast the origin’s FM signal, but it certainly still exists in some markets.
Back to the original post - WTKM is applying to move their FM translator to the antenna farm off Capitol in Milwaukee. This would put the translator on the very most outer portion of WTKM’s protected contour. But, I think it just makes the cut, so it should move forward.
