[Elecraft] RF radiating appliances

[Don Wilhelm]

OTOH,  There are FCC limits for unintentional radiators too.  Yes 
proving that those devices are radiating and making a case for FCC 
action may indeed be difficult, but from what I have found from various 
posts are that Plasma TVs may make a good "first test case".  I cannot 
initiate anything myself because I do not have the problem - the nearest 
neighbor is 1/ mile away and does not have a plasma TV.
