[RFI] RFI LG Refrig Corcom filter and #31 core

[John K9UWA]

That is one very nice looking EMI Filter. I 100% agree with W9RE Mike. If 
someone made a nice package EMI + Common Mode in a nice package I would 
buy a few to pass out to some of my neighbors. It should also have a nicely 
worded advertisement explaining the package in layman terms as to not only 
clean power but also protection for your appliance, TV set or whatever else is 
plugged into the device. 

Thanks
