You guys rocked!
S9 up to +20 here in the Seattle area for hours. Only signal from KH6/7 like
that, for that long, came from the legendary Jack Wheeler, KH6CC. Big shoes to
fill. I'm guessing your toes should be feeling a little bit pinched by now.
Great job!
Looking for you in the CQ WW 160.

Subject: Topband: Some photos and video from our KH6AQ portable operation in
the December Stew Perry TBDC
Dave and I (Rob, NH6V) have been enjoying experimenting with antenna setups on
the east coast of the "Big Island" of Hawai'i in several of the 160 contests
since December 2022.
We run 1500W to a full-size 1/4λ wire sloping ~50° up to the top of a 150'
Cook pine tree across the road from the beach. It runs off of two 130'
elevated radials that run parallel to the coastline and perpendicular to the
direction of North America and Europe.. 35°. The feedpoint is back about 25'
from the ocean and it even gets occasionally hit by the large crashing surf
(!). A pretty ideal antenna, as it turns out.
For RX this year, it was necessary to deploy a single direction K9AY loop in
order to null out a new, S-3 (at 3 kHz bw) power line noise emanating from the
neighborhood about 1km to the northwest. We didn't experience this noise for
the ARRL 160. Unfortunately, the noise is also coming from the same direction
as Japan. So this ended up being our sole receive antenna, and we must say that
it was most beneficial and kudos go out to K9AY for this especially innovative
antenna design. Thank you, Gary!
Driving 4' ground rods into the lava rocks wasn't too easy. There was also a
good amount of seawater wetted sand to help lower the resistance - we're
guessing no better than about 100Ω.
Thanks for the QSOs! Your participation is greatly appreciated by all. We hope
to continue operating from this portable location in all future 160 contests.
Look for our report with additional details on www.3830scores.com - to be
updated within the next couple of days.
