A good friend of mine, Bill Waters W7GKF had TERRIBLE problems from a
low voltage lighting system at a neighbor's home. Despite his best efforts, he
was never able to eliminate the noise.
That neighbor eventually moved, taklng the problem with them.
I will forward your information on to him. Thank you,
