----- HDTV Magazine Tips List -----
Dale,
It's in the set itself. Any set with a CableCARD has a QAM tuner
(external to the card). The CableCARD is just for decrypting - not
demodulating. I've set up several sets with QAM tuners (and no
CableCARD).
The Best Buy link you have is for a STB with ATSC and QAM tuners (with
no CableCARD).
The Wikipedia link is great. Goes into a lot of technical detail
discussing the modulation technique - but does not tie QAM to CableCARD.
