Ed --
Thanks for your input and insight. Of course there is the variability
that you mentioned. I have posed the trap loss question to several well
known antenna designers and have never received a definitive answer (varies
with frequency, depends, etc.) but have heard a figure of 4 to 8% loss due to
traps. I would be interested if anyone could enlighten me and the reflector
audience with further insight. That would make a great article for one of
the magazines. It is also difficult to computer model traps so it's not as
easy to analyze multi-band beams as monobanders.

Correct again but the design and sleeve feed (I've been told) contribute
to greater efficiency than the other conventional trap tribanders mentioned.
Again, a great topic for further study.
Tnx again, Ed, and I look forward to hearing from you again.

BTW -- my field is towers not antenna analysis. My perspective is purely
anecdotal as well as what I've installed, used, heard, etc. By definition,
you work on towers, you wind up working on antennas. I've worked on over 100
amateur stations here in the Pacific Northwest.
PS - The article regarding antennas that I mentioned is only available on
hard copy. SASE to Steve Morris, Box 572, Woodinville, WA, 98072, will get
you a copy!

Message-ID: <8BB354A.0065001D5B.uuout at lun.lis.ab.ca>
Hello all.
I recveieved a lot of feedback regarding my posting for power line noise
vs different voltage power lines. Many people were very quick to point
out the variance possible for various locations and various weather, and
also the pure subjectivity of the matter.
The above is TRUE, however;
It was only meant to be a GUIDELINE to follow, not gospel.
I did, as a matter of fact check the same lines under different weather
conditions, and found that in most cases there was a unilateral increase
in noise during adverse weather condx.
I realize that there may be some of you out there who live across from
the high voltage lines I was referrring to as 'bad', and have no noise
problems.
Power lines are in the same realm as propagation condx; they are always
changing, and vary between locations. This doesn't seem to stop the guys
making propagation predictions though.
Both of them fall in to the class of *Chances Are.........*
I hope some of this was of help.

I have just taken delivery of the Alpha 87A plus Digital Antenna Selector
(DAS). I am now looking for the remaining components to allow selection in
the shack between 3 coax lines and among 5 antennas at the end of each of
the 3 lines. What do I need, and where do I find it? What box do I need in
addition to the DAS in the shack, and who do you recommend I source the
remote 5 position relay boxes from. Tnx for advice/recommendations, etc.

A sudden business trip to Tallahassee allowed me to mke a trip to 6Y5. I should know better
by now then to check any essential luggage, but I did and sure enough AA lost my bag
containing the Windom. It finally arrived early Sunday morning(0300) and I was up nad
running for the last 5 hours of the contest. I used the Windom as a sloper with the base inches
from the water and my trusty, suitably modified HW9-no computer or memory keyer-did it the

To all radio amateurs
It may be hard to believe, but solar activity has edged even lower.
There have been no visible sunspots since the beginning of the
month, and the sunspot number was zero every day last week. Solar
flux was at or below 70 each day also. We should expect more
periods of no sunspots as the current cycle bottoms out over the
next year.
Unfortunately the geomagnetic field has been acting up a little.
The worst period was around 0900Z on February 13 when the K index
was five. 160 and 80 meters are really best when the solar flux is
low, but an active geomagnetic field can disturb the low bands
greatly.
For the DX contest this weekend, a recurring coronal hole could
bring more geomagnetic disturbances. The solar flux should also
edge above 70. The flux should peak at or just below the mid-
seventies from February 25 through the first of March. No big
geomagnetic upsets are foreseen.
Sunspot Numbers for February 8 through 14 were 0, 0, 0, 0, 0, 0 and
0, with a mean of 0. 10.7 cm flux was 67.5, 70, 69.8, 70, 69.1,
68.7 and 68.9, with a mean of 69.1.

I'm sorry but I don't have any experience with the Fritzell antennas that
you mentioned.
A coupla years before I moved over here, VS6 got hit by a particularly
nasty typhoon. Of all the antennas that weren't taken down in advance of
the storm, the only one which failed was a Fritzel (a 3-element, I believe).
Kurt Fritzel's beams & verticals are just what you'd expect from Germany -
very robust antennas, although probably too robust. Whatever alloy tubing
he uses has absolutely no give to it at all. One of aluminum's best
attributes is lost in his company's products. And since this experience,
he lost what was an appreciable share of the local market.

In my view, this is one of the true dilemmas of radio contesting.
You, as the hypothetical "apprentice," do not have the knowledge or
experience to be able to appreciate the skills I have developed that
make me the hypothetical "major league contester." And similarly, I
take for granted many of the fundamental skills that are necessary for
you to advance to the next level.
I like to offer up two quotations that sum up my general beliefs on
the topic. The first is from someone in my peer group, and second is
from someone who I would categorize as a personal contesting hero from
my formative years in contesting, although I doubt he actually knows
this :-) ).
"With experience comes knowledge and cunning. I can't stand here
and tell you the secrets, as many of them are second nature to me
now." -- KR0Y/5
"The best of the best gained their winning edge practicing the basics
over and over in numerous forgettable events, often using inadequte
radios and second-rate antennas. Discovering how to overcome such
obstacles are lessons never forgotten." -- NCJ Profile of N6RO
And now for a bit of a digression:
I have observed many "second tier" (and others down through the
neophyte ranks of) contesters think that there is some set of winning
"tricks" that the "first tier" contesters use to beat them, and if
only someone would let them in on these terrific secrets, they would
be first rate contesters themselves. These people are setting
themselves up for disappointment, because I'm going to let them in on
the biggest secret of all:
"There are no secrets!"
It turns out, as with most things is life, that skill and hard work
pay the most reliable dividends in the long run.
Now for some specific advice. None of these things are mandatory to
win, but collectively they really add up:
o Know the code. 50 WPM conversational is a nice milestone --
note: don't try this at home with pencil and paper.
o Know the bands. Nothing like knowing the right band to be on
to improve your score.
o Know your station. Knowing whether or not your station has the
gusto to run people or crack pileups under given conditions
on a given band is a real time saver.
o Stay in the chair. You can't be the loudest station on the air
if you are not on the air.
And now for some general advice:
o Operate a lot. Experience is king. I learn something every time I
operate.
o Solicit advice from a variety of experienced people. Some of the
"experts" will be more compatible with you on a personal level than
others, so shop around and get a variety of points of view.
To wit, after I post this message, I will get a few notes from various
folks, about half of which will say "I really identified with what
you wrote. You're a genius!" and the other half of which will say
"You're a moron. Get stuffed!"

THESE ARE NOT OFFICIAL SCORES!! DO NOT SEND ME ANY LOGS!!
PLEASE DO NOT POST ANY SCORES TO THE CQ-CONTEST REFLECTOR!!!!
Send scores to the 3830 reflector or to me direct.
These scores are put in the classes by what the person submitted them.
Please do not email me and tell me there is no such class or it should
be called something else. I only by what the individual sends me.
I believe to subscribe to the 3830 reflector email 3830-REQUEST at akorn,net
and put subscribe in message body.
Please remember if you do not give me a class that I can figure out you
will be put in the Unlimited Class. I have no way of reading your minds.

Message-ID: <199602221539.MAA14024 at fama.ibase.br>
Dear friends,
I intend to buy a new amplifier which delivers 1000W (maximum legal
power in Brazil). I have been thinking about the AL80B.
If you know this amplifier, please drop me a note with some comments. Please
inform the Real power output (SSB and CW). I would like to know also if
it is rugged, that is the most important attribute that I am looking for!
I worry about the bandswitch because I had problems with my FL2100Z.
Thank you very much and Good Dx,
Carlos - PY1CAS
E-mail: silver at ax.apc.org
ps. Another possibility is the Ten-Tec Centurion, however I think that it
delivers much more than 1KW. Is that right?

Subject: Power Line Noise
Message-ID: <24960222162542/0005543629DC1EM at MCIMAIL.COM>
A few additional comments re power line noise:
You may find that a QTH that seems quiet with a simple, low antenna
becomes quite noisy when you put up a real contest antenna. For
example, my QTH is very quiet on a low tribander, but I get a lot of
power line noise from antennas that have vertical patterns optimised for
low angles. In addition to the daily and weather variations, this is
another way to run into unexpected difficulty with a new QTH.
Also, with regard to various power line voltages, there are two distinct
types of line noise, spark discharge and corona. You can see the
difference quite clearly by looking at the IF output of a receiver with
an oscilloscope, especially if you look ahead of the narrow filters.
Spark discharge has one or more distint spikes at the voltage peaks of
the line voltage. A discharge can begin with one spike, but as it gets
worse you can see up to 5 or 6 spikes at each voltage peak. This is
the discharge of the capacitance of a high resistance contact, and is
almost always caused by the pin-and-clevis joints in the multiple bell
insulators you see wherever the direction of the line is changing at a
pole. This can be fixed by getting the power utility to replace the
bell insulator string with a single-piece insulator called an Epoxilator.
Of course, it doesn't hurt to worry about the issues of loose hardware,
and the hairpin springs are worth it if you can get them to install them.
Very high voltage distribution lines, such as 230 kV, are another problem
altogether. They are prone to corona discharge, which instead of narrow
spikes looks on a scope like white noise modulated by a rectified 60 Hz
wave. You can't touch corona noise with a noise blanker, and it has a
different sound to it because of the strong 120 Hz component. Most utilties
are very reluctant to touch these high voltage lines, because they don't
want to take them off line for service. Corona can be caused by something
as simple as a small piece of wire resting on the line or a sharp metal
point where the line is held to one of the big insulators. Out local
utility washes the insulators once in a while, using a helicopter with
an insulated "diving board" that the hose operator sits out on (not my
idea of a great job!). But if you have corona, the only way you can
get it worked on is to convince the utility that the line has been
damaged (they worry about gunshots) and may fail, and that the noise
is a preliminary sign of failure. Good luck, it's better to avoid the
very high voltage lines even though they have a generally good reputation.
The problem with line noise is that it costs the utility nothing in the
way of lost power, so they aren't very motivated. Most are more
responsive to TVI complaints. Out local utility has a terrific line
noise technician, but he has a hard time getting any action once he has
identified the problems.
I agree with the opinion of several top contesters with whom I've discussed
noise problems: if you have line noise, you lose the bottom layer of
weak stations that you could otherwise be working for a real difference in
a contest score. The best locations in the world (EA8EA, PJ1B, for example)
are absolutely quiet, and the difference shows in their scores.
