91.1 FM Nascar speedway station in Concord now in mono

I noticed that the Christmas music broadcasted on 91.1 FM {Low power station at the NASCAR speedway} is now in mono. Anyone know why it's not in stereo?

The range does seem further..

Experience has shown that running stereo reduces a typical FM station's maximum possible range by a third. When a mono FM station adds stereo to its signal, the signal-to-noise performance of the signal deteriorates, and the effective geographical coverage area of that station is reduced. For a 100kw blow torch this means very little, but for a LPFM stereo can be a great detriment to decent coverage.

Charlotte Motor Speedway is a PRN track...The FM transmitter is operated by the PA System guys so I would suspect the PA system is on that channel. I believe they use it as a cueing channel.

If you are at the track with a scanner you can search and find real time feeds of the radio broadcasts in the 450/455 band as well as 454.0000...

I Observed This Back In The 1980's When WXRC -&- WRFX were setting up shop. Switching the Sansui Setting to "Manual" increased the Signal From A "S4" -to- A "S4.5". Not a big deal to My Setup; Just An Observation.
