Many television stations and communities or cooperative groups operate or operated translators (somewhat like repeaters) before the change to digital television. Due to the frequencies changes, signal propagation changes and financial considerations that came along with digital television many rural areas have lost some or all of their over the air (OTA) signals.
This issue may be compounded in the near future as the Federal Communications Commission (FCC) is trying to clear more spectrum for mobile communications and will be (from what I understand) incentives to give up their "assigned spectrum" for government auction to the mobile provider industry.
I am not fully aware of all the implications of the so called "repacking" of the television broadcast spectrum after these auctions but I have read there are little or no provisions for OTA translators.
I’m not very confident the issue will receive much attention as with most government issues today are generally founded in revenue issues.
Perhaps SCF JEFF will be able to shed more light on the issue as he is currently directly involved in the broadcast industry (My last gig as a broadcast engineer was fifty years ago! ? )
