The best option for a daytime only signal would be to turn in the license, but we all know that wont happen with Mid-West Family. Look at 1480. That was SUPPOSED to go dark years ago. I'm not sure how they get away with continuing to hold that license.
That is an excellent question. The whole idea behind the "expanded band" was to move stations over to it and they were supposed to turn off their old station forever to eliminate some of the interference on the AM band nation wide. WKSH in Sussex moved to 1640 and immediately turned off 1370. So, just how does Mid-west Family get away with keeping 1480 on the air?
