KZOK 102.5 FM Audio

Was wondering if anyone has knowledge of what happened to KZOK’s audio? It sounds like a 24 Kb/s MP3, which is to say horrid.  Pretty much anything over about 8Khz seems to be gone, but it sounds like there is a big peak just before it rolls off and everything sounds squished.  This has been going on for several weeks now.  I received no response to an inquiry I sent to CBS Radio.

Whatever it is, I sure hope it’s not permanent.
