Can't iHeart just say "Screw it. AM is dead" and abandon it?
I get his point. Mine is that an AM with 3 towers is more expensive to run than FMs with one. Making it a donation would be a cruel joke.
But no, iHeart can't abandon it. They are a legal licensee, subject to the law. If they abandon it, they get fined. The FCC knows where they live.
iHeart has a bunch of these boat anchors, and they're stuck with them.
