I've noticed for the past couple weeks, 90.7 KVIT and KTAR-FM have been broadcasting in beautiful "FM mono." I can't see the purpose for either (KVIT is a music station now feeding a stereo translator with monaural audio, and KTAR is a South Mountain FM with RDS and HD). Now, if it was a new spoken-word format on a marginal stick, I can see why they would have done this.
