The problem Dish has with HD in small markets is that they are bumping up against the requirement that if they carry one channel in a DMA in HD, they must carry all the HD channels in that DMA by certain dates the percentage of these DMA's is rising and Dish does not have spotbeam room to add more markets when they are being forced to fill up markets they already carry.
My Lubbock market for instance, has 9 OTA HD channels with CW, MYTV, Univision and Telemundo in additionto PBS, ABC, CBS, NBC, and FOX. That would be a very large chunk or spotbeam territory for one DMA - and the only satellites that have spots that hit us are 110 and 61.5 (our SD locals are on 110 now) and they just moved more CONUS RSNs to 110.
I don't know if there are spots available to even give us HD locals for 9 channels.
Bottom line, it's not as simple as turning them on.
