if you scan the AM band in the wee hours it is difficult to pick-up any program BUT Coast-to-Coast. It is probably past it’s saturation point.
There is also Phil Hendrie and his characters, etc. But add McIntyre (and Carr reruns in Boston) to the mix.
Citadel decided to stake out the 10 pm-1 am slot (ET) with a live show hosted by Curtis Sliwa but they eventually let Sliwa’s contract expire and replaced him with John Batchelor.
Now Citadel is going after the 1-5 am slot.
