[Elecraft] RF radiating appliances

[David Christ]

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 the heck they are and why they might be on continuously is 
beyond me.  This is an unattributed report and is the stuff urban 
legends are made from.  I'll probably be trying to follow this up.
