Re: [Elecraft] RF radiating appliances

I caught the tin foil leaning. Also understand the remote meter technology. They use it here and it has nothing to do with appliances. It was this sentence that caught my eye: Bosch customer service confirmed that both the washer and dryer we have on order contain power transmitters. What t
