FWIW, the so-called technical advice on the Lutron website is mostly a bunch of
technomumbojumbo doubletalk, and your buddy redacted isn't much better. Since
the dimmer mfrs refuse to make RF-quiet dimmers, my solution is no dimmers.
Blame everyone but themselves for the noise their dimmers generate. It's not
the contractor's fault, it's theirs.
