[CQ-Contest] RFI Faucet

[Joe]

That was my first thought also. I wonder how noisy to YOU that faucet 
might be?

I know a touch lamp on the wife's side of the bed I kill on 40 meters, 
it has three brightness levels and of course off. With every dit it 
changes a level. and when it is on it kills me on every band. so when I 
plan on getting on, it gets un-plugged.
