AM has much better range plus it can “skip” which can send the signals hundreds of miles. I can recall when the clear channels would have people call from where in the country they were. Clear channels have just 3 call letters and share broadcast frequency with no other station.

That was in E. Tennessee. They used to boost the wattage late night in the olden time.
