Well, after nearly a year of putting up with my neighbor's noise issue, it disappeared. I hated to do it, and I thought nothing would come of it, but I ended up going to the FCC about it. Low and behold, 5 months later I am clear again. I can't say for certain it was Uncle Charlie, but the neighbors would not talk to me, nor would the home owners. But, 5 months after the complaint the noise has disappeared. I wish there was a way to tell if they received a letter or not.
