Field Day 2001 Post-Mortem Part One
Another Field Day has come and gone, plans exercised, situations
handled; new problems created and old problems solved. The purpose now
is to look at what happened, look at what worked and talk about what
didn't in the hopes that we can do it better next year.
First, let me say THANKS! to everybody that helped. To Steve for
securing the Field Day site -- let's do it there again next year! To
Howard for transporting an unbelieveable amount of equipment and endless
calm. To Carl for helping everywhere, remembering things others forgot,
and being a willing soul when difficulties demand. To the Friday Night
Gang of Car DXers -- Doug, Art, Yumeng, Kongwei and Steve. Great way to
spend Friday dark-time!!! To everybody who 'helped' put up my tent in
the torrential downpour... hihi. To all the kids this year who made it
a lot of fun. To Liu for cooking everything all the time! To Jeff for
bringing the great cake. To Doug for being the great experimenter
despite feeling crummy. To Norm for cranking out the 15 meter
contacts. To Bill for being Mr. 80 Meters and being always calm and
fun. And to everybody for not yelling at me as I cursed the ground
anchors. We'll have a blast again next year.
A lot of feedback so far, definate patterns emerging. To start: Nobody
had fun with the ground anchors! The native rocky soil and spiral-type
anchors just don't go together. We spent about 3 hours total just
getting anchors in and out. Not fun. But if we have towers we need the
guys anchored. Another choice might be the answer; more on that later.
Putting up the towers is otherwise fun. Working a long time on one
project by yourself is not. Teamwork is fun when the leader is having
fun, not fun when the leader yells. Precious little of the latter this
year, we're gaining trust with each other year by year and small things
don't seem to annoy anymore. We're addressing problems as things to
solve not as personal intrusions, and this year was lots more relaxing
than I recall any prior year.
Playing radio and making contacts is fun. Everybody has their own pace,
some have a favorite band, others a favorite mode. This year we might
have had enough CW ops there to run two CW stations almost constantly!
Definately something to think about for next year.
The Saturday Night Dinner is a lot of fun. I think I gained five
pounds. Good sausages well cooked! And plenty of food.
Setup. We had enough folks Friday evening but not enough equipment to
set up. Saturday we had almost enough people to set up but not enough
time as rain kept us indoors until 11 AM. We started operating on 15
meters around 3, one hour late, and were fully set up close to 6 PM.
Have to find a way to reduce setup time.
Running coordination. Since we're so close physically we can't run CW
and phone on the same band at the same time. I made up some "station ID
cards" indicating band, and strictly enforcing "you can only run on a
band when you have the right card on your radio" really helped reduce
problems. Now that we know that we can address the few remaining
interference problems. Next year we'll very strictly enforce the card
scheme.
Antennas. They are making and breaking our efforts. This year we had
one major antenna OOPS! We got the A3 triband yagi up pointing
backwards somehow. Despite all the eyes looking at it, including mine,
we got the thing up pointing east instead of west. Since it was fixed,
not on a rotor, we couldn't fix it without a lot of work which we
decided not to do. We discovered that while it might not be a Force12
it definately has a front-to-back ratio that puts the back lobe well
into QRP territory. 20 meter contacts were almost impossible off the
back of that beam driving 100w! Without any pileups there were many
stations I called and called who couldn't hear me at all. So I drove my
Honda Civic up next to the building, put up the 20m car vertical, and
tried. Better but still not good. 20 should have been one of our very
strong bands but ended up very poor.
The R5 vertical is OK on 15m but lacks gain compared to the A3 we used
last year. A 132 foot dipole at 25 feet works pretty darn well on 80
out to about Ohio, then it gets sketchy past there. No surprise, just
another "radio fact of life" playing out. Even with a horridly
mismatched spliced-up feedline -- 70 feet of RG-58 (!) feeding two runs
of 450 ohm ladder line twist-tied together (that's right, no solder!)
gave surprisingly good results. Imagine what a real matched feed would
do...
The 40m dipole was useless this year. For some reason the darn thing
just didn't seem to work! No idea why, it was fine last year and KF2DX
loaned his SWR meter, which saw nothing wrong with the
antenna-plus-feedline. Ended up not being an issue as Doug used the
V-Beam with great success on both 40 SSB and CW, and 80 meter CW.
The V-Beam -- great antenna! As Siegfried pointed out in last month's
issue, half a rhombic works pretty darn well. Doug strung up two 280
foot legs, 25 feet high at the feedpoint at about 6 feet high on the far
ends, pulled pretty taut. Worked very well, though tuning was a bit
sharp on 80 meters. That was a function of the leg length -- you can
"properly design" them to a particular band and they behave very well.
Experimenting is fun, and we learn so much!
Commercial power and running water are both good things. Tenting in
torrential downpours and high winds can lead to sleeplessness. But
camping is definately a good thing. Doug's big rolling house is very
very cool, actually made a few of us think hard.
So, what about plans for next year? The bulk of that we'll leave til
next month, but for now start thinking "wire antennas". Rotors and
beams are doing great on 6, 2 and 440 but I believe we need to think
"big pattern, stationary" for HF. I have some definate thoughts, let me
know if you do too and we'll continue next month.
73, Mike N2VR
