In order for residents that truly fall outside the digital TV transmission footprint to receive a signal, broadcasters will either have to raise their power levels, or set up a repeater station to reach those who are out of range.
The FCC recently ruled that stations can use a network of digital transmitters, rather than one tower, to extend digital coverage, but critics say it's too little, too late. It allows, but doesn't require, broadcasters to apply for a waiver to use a network, and it's unlikely the work will be done by Feb. 17th.
Ideally, once the transition occurs, the FCC should send engineers to those areas with no signal to determine what can be done.
Consumers who are receiving poor signals and want to ensure over-the-air TV remains free should call the FCC and local elected officials to complain about poor service from their local broadcasters. If consumers lose a station once the digital switchover occurs they should call their local station and let them know they are no longer receiving their programming; chances are they don't want to lose viewers.
