Bob,
One of my interests in radio and television is Hispanic; my interest in radio goes back to the night I discovered at 13 that on my mother's AM table radio I could pick up far distant stations, something up until then I never thought possible. My interest in Hispanic culture goes back to my taking Spanish courses in high school and college. All that to explain that one of the databases I keep is U.S. metropolitan areas (MSA's) without a full-time Hispanic radio station.
According to my records, St Louis is the largest market without a full-time Hispanic station, although Radio Cucui comes close over WEW, which claims to be the oldest radio station west of the Mississippi (it was put on the air by the Jesuit college there in the 1920's). Pittsburgh is second. While St Louis has 70,000 Hispanics at least, it is strange that no one has started the format there, since towns with only 30,000 Hispanics have managed to have viable stations. But Pittsburgh, as you can see, has far less. A year ago I ran "Pittsburgh Hispanic" through a search engine and came up with only one reference, a university professor's study. For whatever reason, Pittsburgh has not attracted Hispanics. The cold weather cannot be a factor, for there are tens of thousands in Boston, New York, Connecticut, Rhode Island, and Philadelphia, as well as Minneapolis-St Paul, none of which is tropical.
