Most stations don't care today about anything except their home metro

As an employee of one of several AM station owners, including CCU and
Disney, involved in a battle over interference from stations in
Northern Mexico, I beg to differ. We care a lot, and have joined in
legal action to protect our signal.

There is also some evidence that IBOC interference can affect home
metro groundwave coverage of adjacent channel stations.
