[RFI] Portable Generator Noise

I purchased a small quiet off brand 1900 watt continuous generator with 
eco mode.  It generates a lot of rfi.  I used it at a POTA activation 
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?
