It looks like KFFS is transmitting as a Analog Broadcast Tv Station , Not Digital.
http://en.wikipedia.org/wiki/KFDF-LD. Most Tv's can still tune the Analog signal that is all but gone now. Analog was the way that Tv was transmitted for 61 years and it's almost gone now. One can call the Tv station and get the latest. The secratery at the front desk will not know one way or the other. You will need to chat with some one at Tv station that actually knows that there are Real digital channels , Virtual digital Tv channels and Analog Tv channels. The engineering department will know.
