I live in the Upstate of SC - about 75 miles from Charlotte. Our local talk radio, WORD, transmits on two AM frequencies (950 & 1330) and they recently added 106.3FM. I don’t think this story is giving the whole picture regarding the talk radio market in this region.
I am seeing some talk stations simulcasting on FM these
days. Recently WPRO in Prov RI and WTAG in Worcester did just that (even in some cases on smaller ‘translator’ stations)
