The Cortez stations KISZ and KRTZ have massive coverage probably reaching about 200,000 people. Of course, with the terrain of that area reception quality could vary. The Farmington stations might reach about 100,000 or more but also San Juan County has had a decline in population over the previous decade. However, the Four Corners has a lot of FM stations so there can be quite a bit of competition for whatever amount of revenue is available for those areas. iHeart still operates a few stations there even though they don't typically operate in small towns. I guess the Santa Fe stations must be doing pretty well for Hutton to expand. With AGM exiting the four corners Albuquerque appears to be the only market outside of California they will still be in, but it is also their largest market too.
