I haven't yet bothered to tell myth about the HD side of my cards. Since it's ClearQAM, it isn't really covered by any lineup I could grab from SchedulesDirect, and that means I have to learn about channel editing. Since my time for this stuff is rather limited, I'm just waiting until after I've upgraded to 0.22, then I'll dig back into it.
In the meantime, I went back and ran azap against what I find, and see that my SNR is as good as it was back on Nov 29, when I put the signal improvement drivers on - if not better. I still don't have a very good signal for the 2 public access channels - but I didn't then, either. As I said, there are still a few tricks I can pull for signal improvement, but haven't taken the time to do, since everything else is working pretty well.
