FM translators used to be a very minor part of the radio business. Following several FCC decisions, they have become really huge, and the directory has to deal with them.
There are five normal uses for an FM translator
– filling coverage gaps for a commercial FM station (West Virginia?)
– allowing non-commercial FM stations to have coverage beyond their main station
– allowing satellite broadcasters to have a national network
– rebroadcast of HD2/3/4 channels not heard on analog radios
– rebroadcast of AM station on FM to “save AM radio”
There are 6,665 translators currently. 1,384 are in the 5th category – about 1/3 of all AM stations.
All translators are simulcasts, but not all simulcasts use translators. An owner can put the same programming on two or more fullly licensed stations AM/FM or multiple FM
For volunteers, I incorporated the lists of translators and simulcasts into the “needs review” list. Sometimes, but not always the frequency of the translator or simulcast(s) appear on the main station. With links directly to the other stations, you can verify the simulcast at the same time without having to deal with groups of unrelated transmitters.
On the other hand, if there is a simulcast listed, but that frequency is not listed, that could be a strong indication the simulcast ended and further research is necessary.
This station is an AM radio station in Las Vegas NV on 1100 kHz. According to the FCC, it has a translator on FM at 100.9. If you look at the screenshot carefully, you can see the translator is listed.
Many times, the translator or simulcast is only shown in a graphic, so can’t be connected automatically. In this case it is clear, so you can click through to the translator and mark it is complete and get a “two for one”
