Tom -- Yes, I'm pretty sure I have HD self noise on one station, especially since another station of similar strength (at the tuner) without HD sounds quiet.
But you had seemed to imply (in your earlier post) that good post-detection filtering (or a better stereo decoder?) could compensate for a wide IF pass-band. That was the reason for my question about (2). Did I misunderstand, or can you get rid of the self-noise by post-detection filtering
without increasing distortion by using a narrow IF?
The answer to this question would seem important for choosing a tuner to get great analog sound on a station with HD channels... -- Clark2
