W7ZOI Field Day, 2011
w7zoi, June 27, 2011
Our operating position.
This was a complicated year for Field Day. It seemed that folks were
busy and it was difficult to put a trip together. But in the end, Roger
(son, KA7EXM) and his son Peter were able to join me for a walk in the woods.
As in the past, I really wanted to go to the mountains rather
than do anything on the flats next to a car. I'm a perpetual sucker
for the integration of some adventure with my amateur radio. In addition,
I figure that I should do these mountain walks while I can still navigate
the hills, for geezerism marches on.
This year was one with a heavy snowpack in the mountains. Much of
the winter precipitation had been close to average.
But it continued raining and snowing as spring arrived. Snow
often creates a challenge in the Pacific Northwest for those who want to
hike to a mountain FD location, and it was even more extreme this year than
The FD location we picked was one that we suspected would have a lot of
snow, but would still be relatively easy. We selected Mirror Lake,
a tarn just south and west of Mt. Hood. The hike to this location
is especially easy and is, hence, popular with families. Continuing
to climb beyond the lake takes one to the top of a neighboring ridge that
offers good views and hopefully, better propagation.

and Harry Mountain in the background.
We reached the lake in just over an hour of easy hiking. The snow
appeared as soon as we left the lake. We continued to the point where
we hit the ridge top where we ate a bit of lunch before continuing through
the woods toward the summit. By now the snowpack in the trees was
continuous at a mean depth of a few feet. We got to the top of the
first peak of Tom, Dick, and Harry Mountain in another hour or so of moderate
hiking. (Who knows which peak is which!)
This is yours truly on the summit ridge of
Tom, Dick, and Harry Mountain (TD&H Mtn) with Oregon's Mt. Hood in the
right background. The distant peak just over my right shoulder is Mt.
Adams in Washington. We operated from the summit of Adams in
August of 1967 in a memorable adventure.
Our elevation on TD&H Mtn was only 4920. The rock
on the ridge top absorbs enough sun light to melt much of the

Peter's feet can be seen at the lower right corner of the photo.
While it might not have been difficult to go on to the other summits, they
are listed as being "off limits" to protect peregrine falcon habitat.
(See Sullivan, William L., "100 Hikes in Northwest Oregon,"
Navillus Press, 1993, revised and updated in 1996.) I don't know if
this restriction is still in effect.
Upon reaching the top, Roger and I started getting an antenna up while Peter
relaxed. A short tree on the ridge line begged to support a 40
Some of the junk that we hauled up the hill.
Mt. Jefferson can be seen about 40 miles to the south. A short piece
of rope is used to tie the transmission line off to keep it out of the way
As usual, we took more stuff than needed. A 1 Watt output superhet
transceiver is the main rig for 40M CW. A keyer sits on top
of that rig and a small transmatch is available to guarantee a reasonable
antenna match. Three paper pads were used for this effort.
One was a log, another was a scratch pad, and a third was a cross-check sheet.
Paper clips are a must to hold the sheets in place in the almost constant
wind. A second rig carried up the hill was Roger's Yaesu FT-817. He
carried a small folding 3 element Yagi for 2M. Several contacts were
made on 2M SSB, plus a few more on 40 M SSB. But most activity
was on 40 M CW. It was dramatic how difficult the 40M SSB contacts
were compared with the CW contacts. It was also dramatic to again
observe the low noise and strong signals available in a remote location.
This view, almost due north, shows Mt. St. Helens.

framed by Mt. Hood in the background. Part of the highway can even
been seen along the left edge of the photo. Our location was 1500
ft elevation above the trailhead at the highway.
This shot shows Roger relaxing after having
operated 2M SSB for a while. I goofed and didn't get a photo of that
set up. (Oh well, that means we will have to another trip to get a
good photo.) That antenna was all packed by the time I though of it.
Mt. Jefferson, about 40 miles to the south, is in the background.
We operated for just a couple of hours and then decided to pull up stakes
to head back down the hill.
A leisurely hour or so brought us back to Mirror
Lake where this photo was taken. It shows the ridge where we operated.
The markings on the photo show the group of trees that we used
to support our antenna.
This was a great location, although it lacked some features. We
didn't find good places to camp near the ridge top. I suspect
that more exploration would yield something. The location was a bit
more effort (greater elevation gain) than some of our FD destinations, although
it is certainly not a difficult hike. It would be much easier in normal
years. The ridge top might even work for a winter destination.
We have often been to Mirror Lake in winter on snowshoes and have
even been to the ridge top. Roger and I both agree that we should have taken
bivouac gear along and stayed on the ridge overnight.
This was a magnificently scenic place. Not only was Mt. Hood "in
your face" close, but four other major glaciered peaks could be seen.
It was also a good place to look for other potential, even more remote
