I wonder if it would be feasible for iHeart to engineer some sort of night coverage from the current 1190 day site. Would likely involve rather dinky power, as well as coming up with appropriate directional patterns from the four existing towers. It might not be any worse for Metroplex coverage than the present night site, which misses a large portion of the market. I could see a COL change to one of the mid cities in such a scenario.
Nothing would change with the day coverage, which is quite good. And KFXR would be rid of 12 towers, whose land could be sold.
