I haven't seen any articles saying Talk Radio is affected by MF/CFR. I think radio shows are exempt because they're part of tradional old media that isn't involved in lobbying according to MR/CFR. The Left is trying to regulate radio by bringing back the "Fairness Doctrine." As a great philospher once said, "the world is an endless power struggle."
The Courts shut down our talk radio here in Washington state during the last election.
