OK I got an electronic converter box to better debug the issue and it has 3 meters: signal strength, signal quality, and symbol quality. Signal strength is pretty good... 94%-100% and pretty stable.
Signal quality is a lot worse. It is much less stable moving +/- 10% all the time and varies a lot by channel. One channel (9) ranges from 45-85%. Some are in the 80s and 90s. As soon as they drop below 50% it would break up and symbol quality would drop to 0%. This would happen with signal strength still at 95%. I tried removing the pre-amp from the system and all that did was drop my signal strength by about 30 points. Didn't seem to have any positive effect on signal quality. What should I look at to improve this?
