While the main station was off the air the translator was on the air simulcasting the fuzz. Crazy but true. You'd figure they would use it to broadcast the station even though they were having problems with the main signal.
FCC rules say they have to feed the translator via an off air signal... So if the main signal is off air -- the translator in theory should be "off air" too..
[Now in theory they could use an HD-2 of another one of their FMs to feed it..] but as other said here Wilks doesn't' seem to be interested in HD (even though FCC records show at least 107.1 broadcasting an IBOC Signal].
Not True
My translator licenses have no such restriction. I feed mine with a T1 circuit.

There's an exception for AM stations that allow them to feed translators via other means. In most other cases (except for when they are considered "fill-in" to the primary station), commercial band translators must be fed via off-air pickup.
Most translator receivers have an output to take the translator down if the primary station goes off. However, since that's usually based on a signal level threshold, sometimes it doesn't work if there is heavy tropo or other signals keeping the received signal level above threshold.
