Subject: How many hams? de K3ZO
Message-ID: <199502031442.AA12492@mail.crl.com>
I got this repsonse from K3ZO and thought it was worth reflecting.
Hey, Bill, good to finally be on the Internet!
Re the subject at hand, at a contest forum at Visalia a couple of years
ago I was asked to make one prediction about the future of contesting and
I answered: "The West Coast will rise again." There is tremendous growth
in ham radio over there. I was at the recent IARU Region 3 Conference
and Taiwan alone is talking about adding 200,000 hams to the BV ranks in
the next few years, once they establish a no-code license. (They
presently have only one license class, which includes a CW exam of about
15 wpm). The Chinese reported that 1400 people took their first HF
home-station-license exam in 28 different Chinese cities last July.
Thailand reported 93,000 hams, almost all VHF/no-code. India reported
9000 hams but only 4500 of them have been able to afford to buy or build
a rig. Both China and India talked about eventual plans of their native
industries to start cranking out inexpensive CW/SSB only rigs for the
local market. Japanese imports are just too expensive. My occasional
sessions from HS0 show me that there is tremendous growth over there
already just based on what I hear call me each time I fire up from there.
Will no-coders ever take to contesting? My friend HS1CHB has started a
monthly VHF sprint contest in Thailand precisely to try to make this
happen, and it has been a great success. It doesn't hurt that six
trophies are presented at every monthly meeting of the Radio Amateur
Society of Thailand to those who won the various categories of the
previous month's sprint -- almost immediate gratification! Once those
guys start thinking about where to go next in contesting they will have
to think about upgrading, and then what? How about 93,000 HS's in the
CQWW? The mind boggles!
Why aren't the 1,000,000 JA's in con
testing? The W6's used to get much bigger pileups from Japan than they
do now and are puzzled by it. K3EST who goes to Japan every year says
it's because RFI has gotten to be a big problem for JA's operating in
close quarters on HF. Some W6's say that a lot of JA contesters got sick
of working only W6's and don't call them any more. But whatever the
reason, the enthusiasm shown originally by the JA's will show up in other
Asian countries as their citizens first take to the HF bands in large n
umbers
At least that's my optimistic prediction!

Subject: EWE & Beverage Tips
Message-ID: <2F326851@msm.ATK.COM>
I read WA2WVL's article with keen interest.
I haven't tried a EWE, but here are a few observations (from a EM
ant-designer sorta' guy):
The real benefit to using this antenna is the front-to-back. In my case, I
have a severe line noise problem (despite living in the boonies), and such
an antenna with its null placed at the noise direction could result in
significant signal-to-noise improvement.
As reported, I was dissapointed, but expected, the high-angle of radiation
from the EWE. The horizontal wire is an "approximate" transmission line,
with some radiation (due to the low height, it will be high angle). Also,
with the relatively short spacing (assuming 2 phased short vertical
elements), the half-power beamwidth is quite broad; therefore, the antenna
really doesn't have a directional characteristic (unless phased with other
EWEs as WVL explained); merely a null.
Nevertheless, a very inovative idea to WA2WVL's credit. Wished I'd thought
of it. It certainly seems worthwhile trying, and I may do so anyways.
Walt, K2WK, asked for some beverage ideas. I have only one 300' beverage,
but here's my tips:
I first was told by many people that 300' would be too short, and that it
would work like (expletive deleted) on 75m. Yet, I looked at it on NEC, and
it certainly had a directive, if somewhat broad pattern, so I went ahead
anyways. In short, I am amazed how well it hears compared to my 70'
vertical. A 4X4 who was Q3 on the vertical last Sunday night was an easy Q5
on the beverage (oriented east, I live near Minneapolis, near epi-center of
blackhole country). The line noise disappears.
I made a modification to my beverage from what is typically shown in the
antenna books. Ripping off from ON4UN, I used a shielded stub down lead at
the termination side. This is done to avoid "summing" an omni-directional,
high-angle, vertically polarized component which ruins the directivity. In
other words, it prevents adding the response of a short vertical to the
otherwise directional, low-angle beverage. From there I made a slight (not
astounding) departure: I applied the same shielded stub to the feed side
(balun ground side), since that wire is certainly part of the beverage
antenna, and will also "sum" omni-directional, high angle energy. I tried
wire vs. stub, and wire-only certainly degraded performance, at either end
(qualitative evaluation only).
The beverage is only 4' high. The stubs were 4.5' sections of RG-58/U, with
~980 pF capacitor in series to cancel the inductive reactance of the stub.
I tuned the stubs for 3.8 Mhz using an Autek RF-1 analyzer, which by the
way, is ideal for this sort of thing (the stub and cap are low-Q). The stub
and series cap then nearly provide a 0 ohm shunt to ground with no vertical
field response. The braid is soldered to the center conductor at the bottom
(ground potential), but isolated from the center conductor at the top side.
Because I am an anal-retentive perfectionist, the termination resistor (560
ohms) and the cap run horizontal (4" length) on the termination side,
whereas the stub runs vertical.
Also, I recommend E field (metal cover) shielding your balun. The magnetic
shielding is there already if you're using toroids. In my case, I placed
the 980 pF cap inside the balun box, connecting one end to the balun ground,
the other to a terminal insulated from the box (the box is DC connected to
the coaxial receptacle, and the balun ground).
You can parallel stubs to get broad-band coverage. It's in the ON4UN
lowband DX book.
So there's my new tip: put a shielded stub and cap on both sides of the
beverage. You guys with 1500' bevs probably are dying laughing, but as
Jeff, K0OD implied, us real-estate starved guys are desparate.

See this month's QST for a good article on these antennaes. Don't
require much room at all! They are directional receiving antennaes.
Weather permitting, I'll be putting up two this weekend on a medium size
urban lot--one for 80 and one for 160.
Good luck

Subject: Wilson System 36 beam with 40 meters
Message-ID: <199502031651.JAA05891@bock.ucs.ualberta.ca>
I have a Wilson 6 element tribander for 10, 15 & 20 meters and I have
installed a Wilson 40 meter modification kit ( 33-6 MK ) in the driven element.
With the traps installed in the correct direction the antenna would not load
on 20 M and resonanted poorly on 40 Meters. 10 and 15 meters were OK.
Without the 40 traps all bands work properly.
Upon removing these traps and grid dipping them I have found that they are:
- identical
- the naked trap by itself dips at 13.0 Mhz
- with the 22.75 inch length of pipe on the boom side of the trap attached
they dip at 12.24 Mhz.
- Adding the element ends to the non boom side of the trap does not change
the resonant frequency of the trap.
I would expect that these traps would have to resonant on 14.2 Mhz when
installed on the beam so that they are a high impedance on the 20 meter
band. I would expect that the element length from the 40 meter trap to the
15 meter trap would be part of the 20 meter resonant circuit.
The outside shell of the trap is connected directly to the element on the
non boom side of the trap whilst the boom side of the shell is not
connected to the element. This is as per the instructions.
I have looked through indexes of CQ, Ham Radio and QST but have found no
reference to a fix for these traps.
I was wondering if I have some traps that have physically been manufactured
incorrectly as it seems that they have never worked, although they have
never been modified.
Any help with 40 meter traps on the Wilson Beam available out there?

If things work out by this time next week I will be in Costa Rica. The
ticket prices have been confirmed and I just have to go pick them up. I
will probably leave tuesday or wednesday.
Does anyone have any phone numbers for local contest friendly hams.
Personally I would like to work the 160 phone contest. The rest of the
time will be spent having fun (you can have a lot of fun in 2 months).
