Comments:

This contest was a lot of fun.  Long time friend, W5SJ, and new friend, K4UEE,
came to Cayman Brac and for the first time the station was configured and tested
in the multi-operator category.

K4UEE has a lot of experience in organizing DXpeditions and got us on track with
a good operating schedule.  Other than the shared embarrassment of a few mental
errors and another problem out of our control everything worked well and we all
enjoyed the contest.  We lost the Internet for about six hours and we were
without power for 1.5 hours.  That was stressful, and we were lucky to
eventually get some computer glitches sorted out after the power was restored. 

Both W5SJ and K4UEE have great personalities and we had fun.  At one point in
time I asked K4UEE if he thought I should slow down to 44 WPM and with a wry
grin he said he thought that might allow me to pick up some lids that I would
otherwise miss.

After a few tries I worked K3LR on 10m, the only signal that could be heard.  I
thought it might be our only 10m contact for the weekend, but an hour later the
band opened East of the MS River and we had some 10m fun for a couple hours.

After the CQ 160 Contest, my plan was to take all my antennas down and rework my
two homebrew triband Yagi antennas adding a few feet to the booms and a little
better performance with different element lengths and spacing.  The new design
checked out using NEC-4.  After modifying one of the two I found that although
the SWR was perfect on 20 and 15, it did not look good on 10.  This was testing
with the antenna a few feet off the ground and pointing up at about 45 degrees.


Maybe overlooking a mistake but not finding any dimensional errors and not
having the software locally to figure something out, I called on my antenna
mentor, Scott, WU2X, to save the day.  He used his magic to start from scratch
with my taper schedule and limitations provided to give me a new design.  This
time I was very careful and every dimension was most nearly perfect and so was
the performance, matching the curves provided by NEC-4.  I really appreciate
Scott taking the time on very short notice to give me a new design overnight
that works very well. 

The antennas are 2 elements on 20m, 3 on 15m and 5 on 10m - 10 elements on 20
foot booms.   After all the work on my initial design, I had decided that I was
not going to do the work to go ahead with the second antenna, but naturally
decided a couple days before the contest to do whatever was necessary to rework
it as well and get it back on the tower fixed North. It took a day and a half
but was successfully done.

The tribanders are now also fed with new chokes I made using K9YC's work,
consisting of two 11 turn chokes in series.  I also added a shunt coil with
encouragement of K9MA based on W5JAW's design to ground the driven elements for
top loading the tower which is shunt fed with a pretty extensive cage consisting
of four wires spaced a couple feet apart from each other around one side of the
tower.  I grounded the center of the 20m reflector on the top antenna.  My 160m
setup continues to work well though we were disappointed with the multiplier
number on that band, missing four easy sections.

We will be here until mid March. Hopefully will be able to make everything work
for phone contests and get on 160 next weekend and for ARRL phone next month.

Some statistics follow from CBS.

73 from the crew at ZF5T!
