I am not finding this new A2K simple to understand, so I know I have not replied in a timely manner; however, having received the coupons months ago, and got a box at Best Buy, the tv gets most of the HD channels. I think there is some interference with some signals, due to other buildings, so I do not get all the channels I got with the analog signal. I think I will just read more books! Thank you for the input everyone.
