The Cleveland Latino population is predominantly Puerto Rican.The first wave of Puerto Ricans arrived in the 1950's and 60's
And there is the issue.
Per the Planning Board (Junta de Planificación) in San Juan, outbound migration of Puerto Ricans became less than inbound (returnees) around 1968 or 1969.
So first generation Puerto Ricans are going to be, for the most part, well over 60 by now. Not a good base to build a radio station on.
Outbound migration from PR was less than inbound through the late 1980's, when crime and social conditions on the Island gave a start to a new migration, but this time to Orlando and other non-Northeastern rust-belt locations.
Cleveland, like Philadelphia, Hartford, Chicago and other cities in Northeast and Great Lakes areas, has a very old first generation population of Boricuas. The second generation, coming from a time when bilingual education was not a "thing" and speaking English was essential, don't use Spanish language media to any great extent.
The populations in some places, like Boston, have been replenished by Dominicans... and in other places by Mexicans or Central Americans, but not to the extent that the mid-Century Puerto Rican diaspora created.
Of course, places like Detroit, Columbus, Cincinnati, Indianapolis and even Lousiville have significant Hispanic populations today, but almost all are of Mexican origin and are recent in formation, going back perhaps two decades.
