On page 23 of this link is a filter that I designed and W6GJB built for
our HF county expeditions for 7QP and CQP. It's designed to be effective
from 80M to 10M. It was added to the ARRL Handbook several years ago.

For 6M and above, I suggest following the recommendations for
transmitting chokes wound with RG8-size power cables.

I purchased a small quiet off brand 1900 watt continuous generator with

last weekend and it was tolerable by moving the antenna as far away from
the generator as possible. Putting it under heavier load did not seem
to make any difference nor did decreasing the load.
There is a ground lug on the unit but the forest service frowns on
people pounding in ground rods. Is there a more portable solution for a
ground. I have my doubts that it would change anything. I should try
hooking it up here at home and find out.

I did have some big clamp ons and I put them on the extension cord and
that seemed to help some. I could only get 2 to 3 turns through the
clamp ons and I had two. Maybe I need far more turns? I did not the
cabling handy to hookup directly to the car battery to see if the
extension cord was the radiator or if it was all coming out of the
generator.
Has anyone had any luck quieting them down?
