The logical cure for line noise is to notify the power distributor in the area and ask them to locate the noise and eliminate it. I have had good luck in this regard especially if you take the time to narrow the noise to specific poles, etc. If you get little feedback from them, contact the FCC. Its a slow process sometimes but the RFI from power lines can be cured. I have had to involve the power distributor at every QTH during my years of Amateur Radio and had very good luck getting a quiet QTH which involved power line interference; much easier than having to deal with neighbor's devices..
