Popular Q&A
Is anyone having trouble with digital over the air television? | Yahoo Answers

In my area it still seems to be very unreliable.
That is true even for local stations that had
a good signal before the digital switch.

Yes. It sucks! They "sold" it to us by telling us it was better. Explained it to us by telling us that it would free up the analog waves for Emergency Responders and other important people and jobs. I've been asking myself since it started - Why, if it's better, do they want to give it to US? If it's better then why not give it to the people who need the reliability? We've got our answer. It's awful and unreliable. The only way to fix the problem is to sign up for cable or sattellite. One more "plus" for the people who pushed the digi-switch.
