FM translators have become really big business – because the rules are relaxed for non-commercial licensees, it is fairly easy for them to relocate a translator as long as it doesn’t interfere with an existing station. In a major market, a translator originally intended to emit a weak signal to play Christian music can be repurposed as a commercial signal booming out rap music. This is particularly true if a major owner like Clear Channel wants to exceed the rules about how many signals they have in a city. FM translators do not count against ownership limits, even if they are carrying an HD2/3 signal not heard anywhere other than the translator. This is a huge hole in the rules that the FCC recently confirmed is intentional.
So renting out Jesus Music translators is a big revenue stream. EMF (the operator of K-Love and Air1 Christian music networks) has 63 translators that are rebroadcasting non-religious programming – here is an example
I stopped fixing the relationships of what primary station a translator carries several years ago because of technical issues that I just resolved. Most ordinary people don’t care about translators and radio owners are glad you don’t know or care.
