CBS has no incentive to change their ways, since the FCC has chosen to ignore WYSL's complaint, despite being presented with extensive documentation of the interference problems. So much for their claim in their IBOC Report Order that they would deal with interference issues in a timely manner. As others have said, WBZ is apparently on their backup rig.

Re: [IRCA] WBZ IBOC is OFF!
Still on the backup rig tonight, but they've drifted down a bit, to 1030.014. Barry /// Just out of curiosity I wonder if WBZ runs Power-Side on the backup transmitter? I know a lot of stations that had Power-Side before IBOC came along kept it on their backup rigs (KPOF/910 for example). Perhaps I should pose this as a question to the more technically experienced engineer types on the list (Mark Durenberger where are you?). Since Power-Side concentrates the audio into one of the two sidebands of the carrier frequency, would that make the signal appear to be slightly off frequency toward whichever sideband is being used? I know that on an analog radio receiving a station using Power-Side you get the best sound by tuning slightly off frequency to one sideband or another. The carrier frequency should not be effected by Power-Side. But I believe that the apparent center of bandwidth for the overall mask of the transmitted signal would be shifted one way or another. At KCKK/1510 we have Power-Side and we run it slanted toward the lower sideband to help us stay further away from the audio of the 1520 adjacent channel blowtorch in OKC.

I think WBZ runs or at least can run AM Stereo on the backup.

Re: [IRCA] WBZ IBOC is OFF!
Dont count on it staying that way for long. if they're not running IBOC, they're on their 10KW backup transmitter most likely.. that backup can also do AM Stereo too.
