If you use an antenna to receive your TV signal:
At midnight on February 17, 2009, all full-power television stations in the United States will stop broadcasting in analog and switch to 100% digital broadcasting. Digital broadcasting promises to provide a clearer picture and more programming options and will free up airwaves for use by emergency responders.
We have Dish Network, but also have a backup antenna system from which we can receive Channels 3 & 22. We don't lose satellite reception that often, but sometimes during a heavy snow storm or heavy rain, we do lose it. Also, sometimes in the winter when we get heavy wet snow, it blocks our satellite signal as the snow settles on the dish. Don't always feel like getting the step ladder out and the long push broom, trudge through the snow and brush the snow off the dish.
Anyhow, we are going to have to get a converter box and the link below tells you how to do that:
