Doug, I
think Audrey might be looking for a listing of clear QAM frequency assignments digital cable channels. As far as I know, Comcast does not publish QAM frequency assignments. So once a Comcast area goes digital, the only way to know what frequency to tune the tuner in your television to, to tune in (for example) USA Network, is to either have a CableCARD-compatible tuner in your television (with CableCARD installed by Comcast), or by trial-and-error.
Also note that due to a recent decision by the
FCC, granted on request of Motorola, Cisco, Thompson, and Pace, Comcast will now be able to (weakly)
encrypt even those digital cable channels that are available using DTAs. While Comcast has not capitalized on this
FCC decision yet, if/when they do, in most areas, subscribers without CableCARD-compatible tuners (with CableCARD installed by Comcast) in their televisions will be unable to tune in any channels with the tuners in their televisions, other than limited basic cable (local, over-the-air broadcast channels, public access channels, and maybe a few others).
