David, KOMA isn't a dreadful facility. At least it wasn't when it was KOMA. Now as KOKC, it's a weak shadow of its former self. But as oldies KOMA, it actually garnered pretty good ratings - even after the FM simulcast began. Last I checked, KOKC has yet to match those numbers. So, formatwise, KOKC could be considered "a waste" at the moment. But the technical facility sends an excellent signal across it's home metro and (on most nights) an almost local-grade skywave signal throughout the high plains and intermountain West. I used to listen to it a lot when driving through UT, CO, WY or NM at night. During the day, it covers most of Oklahoma pretty well.
The daytime usable signal misses, although barely, parts of several counties in the metro, and at night, about half the geography of the market. That is per the definition of a signal that is not viable.
There is, and has not been for 3 decades or more, any use for the night skywave coverage insofar as revenue generation. While KOMA did a huge business promoting shows and movies in the 60's, by the late 60's most places had local Top 40's and when FM came, it was over.
Of course, one could argue that any AM facility is a bad facility, but this one is not a good one even in a looser context.
