Has anyone else noticed WBZ's unlistenable signal

If I have WBZ tuned in slightly off center on my cheap clock radio, I hear them switch over at 9 AM.  The signal turns to nearly pure white noise.

The IBOC sidebands are transmitted in quadrature, so it's invisible to
envelope detectors.  Only people with synchronous detectors hear it.
