wow...

my upstairs treadmill put out BIG rf  from the nicely constructed driver board.
If it is a 1 hp motor, guess this board is providing lotsa watts.
Interestingly the noise changes with each foot hitting the belt, 
pulling more current. My two adjacent neighbors also from time to 
time turn on their noise makers.    worse on 80, but broadband,,,
