Mike....
Thanks for clarifying. I, for one, didn't think the Cards lost much...if anything with KTRS. I saw it as basically a mix of psychology and nostalgia. A longing for the days of the past as well as the warm fuzzies of the 50kw signal....even though KTRS signal in the daytime is every bit as good ad KMOX, and the KTRS nighttime signal is certainly high quality throughout the metro.
As for others you mentioned, I happened to be in the Twin Cities this year when the announcement came that the Twins were leaving 'CCO. In this case, KSTP's sginal clearly is inferior....day and especially at night. But there are more than adequate ways to compensate for this. Detroit's also sort of a funny one....with the Tigers having jumped from WJR several years ago. If memory serves, they're currently on WXYT, which has a great 50k signal....as long as its pointed right at you!
