Your report repeated for reference:

At one point during the day CH7 had a 100% Symbol Quality at the same time, adjacent CH9 was zero. I did a spectral scan.
Thanks for the new scan. They both LOOK pretty healthy. CH 9 is almost as strong as 7, but 9 has a tilt in the channel level and its pilot carrier isn't as well defined.

The only differences I can find are 9 is running a little less power, its antenna is a little lower, and it is on a higher frequency which will change the scattering of its signal from the rough terrain.

But, the tuner makes the final decision on signal quality (SNR & errors), and it says NO GO for 9.
