The amount of money LOST trying to shut a station down to improve another on AM would be ranked right up there with political suicide. The FCC allowing 1150 to just disappear is one issue that could be a long battle. That's if they didn't take the license back and auction it off for a profit. AM stations are nowhere near as profitable as they once were and the two stations are very unbalanced value wise so just trading 1360 for 1150 is like taking a Cadillac to a bodyshop and bringing home a Calavier. The loss of value or for population served alone in that trade would be bad on the books. Even is the FCC allowed 1160 to shut down 1150 and improve their daytime signal how would that benefit them? They need more night signal that is limited by skywave not 1150. Would 1160 be able to spend hundreds of thousands rebuilding or possibly changing tower locations? Then there is the added electric costs to run the station. How would 1160 ever make that money back? I wouldn't bet on see it happen in our lifetime once you think about the costs involved.
