Maybe the HD transmitters failed. They've been off since last Saturday, which was convenient since there was a tropo and an e-skip opening this past week. I got Kissin 92.5 from Missouri in Battery Park, Manhattan, something that I wouldn't have been able to hear if there was IBUZ. Hopefully the chief engineer isn't forced by corporate to turn the IBUZ back on.
K-Rock is still streaming online.
The only people who would notice the HD is off the air are radio geeks and DXers.
