Far northwest suburbs of Chicago, it's local blowtorch WGN 24/7. On the rare occasions when it's been off at night, I've heard a very weak Spanish signal. Presumably Cuba, but I haven't been able to identify it.
Other Locations: I've logged lots of business trips to both the West Coast as well as Ontario and Quebec in Canada. On the west coast 720 is usually KDWN, although I've heard WGN underneath as well as WGN alone when KDWN has been off.
In Canada, 720 was the home of oldies on CHTN from Prince Edward Island. 7.5kw nights. I'd typically start hearing CHTN
under or mixing with WGN northeast of Toronto. Then on top, if not alone, east of Ottawa
