Here is a website on which you can enter your address and it will tell you what broadcast coverage you can expect now, and what broadcast coverage you can expect after February 2009.We are hoping our CW affiliate hasn't yet switched to digital because that's the only channel we don't receive with the new converter boxes.

The February 2009 date indeed has nothing to do with cable or satellite, but cable can switch to all-digital if they'd like, whenever they'd like (and the FCC is actually pushing them to do so), and satellite already requires every television to have a converter box.As far as I can tell, and what I was told when we purchased the coverters; If you have cable, satellite or a brand new tv, you do not need a converter box.
