This transmission is emanating from the 250-watt LPFM station (W224CD) on 92.7, licensed to EMF (the Air1 people). It broadcasts from a cell phone tower around W.11th Street near downtown Cleveland. The station used to be on 91.9 with only 10 watts, but changed frequency some weeks ago to 92.7 with 250 watts. They have an application to move to one of the TV towers in Parma, dropping power to about 99 watts because of the extra height, but they have not moved yet.
Sometime around 10 days ago, something went wrong (sounds like a satellite receiver locked up) and this noise has been transmitted ever since.
I understand that the EMF home office has been alerted (their local engineering stringer is either asleep or they don't have one), but still nothing fixed as of this date.
What might be happening is yet another Clear Channel arrangement --- like with 99.1 (99X) which was originally an EMF station --- for some kind of Clear Channel programming eventually fed on this frequency. They could be in the middle of some transition right now, so (possibly) no one cares.
