[aprssig] Quieting Honda Generator (was) Portable Ops from 12v via 115 VAC

[J. Gary Bender, WS5N]

For those following this sub-thread, I got a direct reply from Jim, W6RMK, 
pointing me to:
http://www.dellroy.com/W4EF's-Ham-Radio-Page/Portable_Operation/EU2000i_
Filter.htm

The article describes a common mode filter for the AC output that did 
the trick with the 2 KW Honda generator.  Looks like the same problem I 
am having with the EU1000.  The noise seems to be on the AC line but not 
radiating from the generator.  I.e., unplug the AC cord and the noise 
goes away.

I will also try using the generator's 12 VDC output directly to the 
battery when I am hamming rather than plugging the camper into the 120 
VAC output.
