I heard you guy very early probably right at your Sunset, but could not
make a contact till about an hour later. Where there was a nice peak
where you stayed for a very long time. Thanks for everything!

Wes,
We are using EU22i generators, which are the newer version of the
EU2000. You can only hear their noise in a quite place, Also, we are
running three of them paralleled and their noise adds up because they
are synchronized. Anyway, using a bunch of chokes and additional
grounding, we got the noise on 160 m down to an acceptable level.
Also, we now have a well situated DHDL RX antenna that is pointed
towards NA . Last night had no problem copying NA.
TKS for all the suggestions.
GL and 73,
George

George,
I'm not being critical, just curious, I don't have a lot of
experience, but I've used my EU2000 for a couple of Field Days and
from a lot of RV sites and have never even tried to ground the
thing. I park it 50-75 feet away, run an extension cord to the
equipment and have at it. Of course I've never been on a quiet island
but I've not had issue.
Also, you've done this before from Samoa and other places (200K QSOs
I believe) have you not seen this before? What is different this time?

Jim,
We are using all of the cores you have given me. They help, but it is
hard to get a good ground at the top-end of the beach where the sand
is very dry and rocks prevent rods getting driven deep enough to
reach moist ground. Yesterday, a bit desperate, ran a 70 foot long
GND wire to water, but I doubt it is doing much good. We got chokes
on most coax and control cables but without good GND their effect is
limited.
Using a single #31 2" core, how many turns of RG-6 do you think will
give decent choking effect? (I know, it depends on the GND and other
loading factors.)
TKS for all the ferrite cores! Will let you know if we need more!

Hi George,
Remind me where to send you more cores for your next trip. :)
In the meantime, try grounding the generator chassis (and/or
grounding pin) to a driven rod (or to screen/radials if you can't
drive a rod). I've seen reports that this can be effective with some
generators on some bands.

Set up a DHDL RX antenna yesterday but it was picking up generator
noise. Will move it today to reduce noise.
