INX64,

I hope your fix has stayed fixed.

Just a little FYI for anyone looking at this thread in the future with a similar problem.

To feed the power to the booster, you probably have a DC block on the feed line below where the power supply connects or combined with the power supply. These can cause random problems like you described. The first thing I would check is adding a ground on set side of the blocker, and if no improvement, then remove that and it try on the antenna side of that block or booster power supply.

On the old analog system, these issues usually, but not always, showed up as ghosts.
