DavidEduardo said:SirRoxalot said:The noises from a Genachowski-led FCC seem to indicate that there may be more translators, or LP FMs helping along more small market AMs before long.
LPFMs can not run commercials. Translators, if I read it right, can only be issued one to a licensee, and would only fill in some coverage, not replace it.
I suspect "SirRoxalot" wasn't referring to the literal LPFM service but to some new FCC program authorizing low-power FM transmitters for AM stations.
I don't know of any restriction limiting AM licensees to one FM translator. I know of two AM stations (WGNS Murfreesboro TN and WKDZ Cadiz KY) which have two FM translators each. (ironically, both of WGNS's translators are on the same tower!)
The protected coverage of each FM translator is restricted to a particular daytime contour of the AM station -- I want to say 2mV/m but that figure could be wrong.
For AM stations which must sign off at sunset, which must greatly reduce power at sunset, or which have desirable audiences in nighttime pattern nulls, one or more translators could certainly replace that daytime AM coverage that disappears at night.
