That definitely was WTVN you were hearing. They run Sean Hannity from 7-10 p.m. and of course you are within their nighttime northern lobe. 25 miles farther east, you might not be (I've heard no trace of WTVN at night as far west as Painesville). And you're right about where their ring of cancellation starts, so everything falls into place.
WGN doesn't run IBOC anymore either, incidentally, so unsure what hash that would have been.
