[RFI] Whirlpool Washer noise

[Steve K8JQ]

Hi Mike.

I acquired a Whirlpool Cabrio Platinum several years ago and found it 
generated noise that made the lower HF bands pretty much useless. I did 
not check the higher bands.

I wrapped ten turns of the machine's power cord through a ferrite core. 
This reduced the birdies on 40 meters from S5-S6 to very weak, barely 
discernible above the noise level, not moving the S-meter. It cleared up 
80 as well.

The ferrite I used was a Fair-Rite 2631814002. It is mix 31 and has a 
3in inside diameter, 4in outside diameter.
