A big difference is that Chicago is still a reasonably healthy AM market in contrast to Dallas. Plus market #3 is older demographically and less Hispanic (24.3% vs. 17.7%) than D/FW.
Chicago has multiple 1-A (former designation) clear channel stations and several more excellent signals. Dallas has fewer full market signals.
Chicago's median age is 33. Dallas' is 32. No difference of significance.
Dallas is 14% African American and 24% Hispanic. Chicago is 17% in each group. Ethnicity is about the same. And Hispanics have been a significant population group in Dallas for generations, meaning many are fully assimilated and as in need of news as anyone else.
Although I'll add KRLD to my presets and wish them nothing but the best, I don't see "all news, all day" working here. D/FW is in the sunbelt, which has not been a favorable environment for that format.
It generally takes a good facility in a top 10 market to be successful at all news. In the top 10 markets, we have New York, LA, CHicago, San Francisco, Dallas, Houston, Atlanta, Philly, DC and Boston.
Atlanta has only one decent AM signal, and it is a very news heavy talker... and it felt compelled to go to an FM simulcast recently. Houston can arguably be said to have only one near full coverage AM station, and that one is talk with news. In San Francisco, the talk AM had to add FM a bit over a year ago. In DC, the news station left AM and went to FM.
So I kind of doubt the sun belt theory. I think the issue is that there are not that many good AM signals, even in the biggest markets and the most desirable audience is not on the AM band for the most part.
Remember, the sun belt cities had very small populations for the most part when the big AM signals were given out, so with urban sprawl and the growth of FM, AM declined faster in most of those places.
