[RFI] Water treatment RFI - UPDATE

[Kenneth Silverman]

A few days ago I had two Clack WS1 valve/control heads installed on a new
water softener system (just 2 tanks for softener and neutralizer as
our well water isn't too bad).  Turning off the breaker to the control
heads didn't change any RX profiles, so they seem to be RFI-quiet.  They
use small wall-warts (V3186) and the display/control board is always on
(bright color LED screen).  Once I get more ferrite cores I will add them
as a precaution.
