This isn't local, but it's an interesting example of what happens when a low power station is obligated by the rules to give up its frequency because a bigger station wants to take it over. I'm not 100% sure, but I believe the law is similar in Canada, where a bigger outlet can demand a small player abandon its longtime dial position once authorities determine the request is valid. 

Not sure how many times it's happened here, but I believe it has. In this case, it took place in Michigan.

Radio station had same dial spot for decades until bigger station took frequency
