Mad props to KEZK/STL ...

The CBS radio station managed to offer their listeners a special treat around 7PM Saturday evening, broadcasting in quad!  Unfortunately it was unintentional and the two additional channels were airing simultaneously with the station's regular programming.  My intrepid tipster was unable to catch the calls of the "extra value" radio.

I wonder how this could have gone on as long as it did, a time span of approximately fifteen minutes.  Does no one monitor the station?
