There are a couple of reasons Hannity remained on 1230. Primarily AVAILS. You could sell twice as much inventory at better than half the ratings and make more money. I will be interesting to see how they handle the inventory with news and weather sponsors, traffic reports, etc. Not to mention all the network avails they give up.
The other reason was that Curtis (via WPTF) owned the rights for Alamance County. They did the same deal with Rush years ago - which was why it took a year for WSJS to put Rush on the 1200 signal!
