I was roaming the Iowa threads and saw the message about the KCAU situation, which sounds amazingly like the WOI (ABC) situation in Des Moines and the WHBF (CBS) situation in the Quad Cities. ("You'll say I see" is the slogan for all of them.)
In fairness to them, they got handed a couple of bum "out-of-core" DT channels in Des Moines and Rock Island -- who wants to buy equipment for a channel 59 they have to turn back over to the government? Their point about waiting until there are more HD sets also seems valid, and their message to a Quad Cities-area poster is that they're a small, privately-held four-station chain.
But you can argue against these points, too. Cedar Rapids, where I live, has HD available on all of the "big three" networks. One is on a temporary channel 55. Another is on temporary channel 52 AND is owned by a one-station company. Even the Sinclair-owned CBS station started HD this year.
They're taking it on faith that (H)DTV is the future and that the technical issues can be worked out, just as they were worked out for analog TV over the past half-century.
That's the debate you're facing. For better or worse, KTIV has taken one side, KCAU the other.
