If you are in a very quiet location with antennas close to the Honda and
haven't brought other noise sources to pollute your environment, you
WILL want a serious common mode choke on the AC line. We use Honda 2000i
with K3/KPA500 for our county expedition to a rare county for CQP
(California QSO Party). Noise sources include computers, monitors, wall
warts, battery chargers, portable refrigerators, etc. We use no SMPS
wall warts, and choke everything.
The length of AC cable between the Honda and the choke should be as
short as possible. To get more turns through the choke, make a short
jumper with the thinnest practical cable and use it to wind the choke.
#14 indoor wiring cable or #14 appliance cable are a good choice. Wind
the choke before installing the second connector. Follow the guidelines
in Chapter 7 of k9yc.com/RFI-Ham.pdf for coax the size as the power
cable you're using. Use larger diameter and close spaced turns to move
the resonance lower.

N9FN and I have operated portable in various state QSO parties using his
Honda EU2000 with no RF noise we could detect. We often used his KPA500 and
that generator handled it quite well.
