But mix products are difficult to track down, let alone eliminate.
You'll need to find, and isolate the point at which rectification is
taking place, and that could be ANYWHERE...wherever metal components in
any structure touch, you can get rectification, which will product mix
products from the environmental RF. It took me a couple of years to
finally track down and eliminate the mix products being generated on my
property. Padding down the antenna input also helped.


You really ARE in the Little Big Horn for noise and interference.


A 20 dB pad will help the swamping. Have you tried an MFJ-956 preselector?


Not yet, but I've been thinking about a preselector. *Does the MFJ
work well?


Save your money until you find out definitively whether your RFI is actually
coming in internally or externally, and if it is external, the ONLY way to
resolve that issue is trying to get something done with your local power
provider.

I don't disagree - but it may be that the only way to determine
whether the problem is internal vs. external is by spending at least a
few $$. I can do this.
