WFAN 660 (NYC) early in the morning, listening in Ohio, has a pretty
loud AC hum along with it, except I can put an antenna null on it
and take the hum out without taking out WFAN.

Which suggests some (probably Cuban) other station is putting out
a hefty AC hum.

I doubt it.

It is really tough for a Cuban to just hum. Usually, after a few bars, they
break into song, and tap the rhythm with their fingers or hands.
