Greetings, All. I hope
the world is treating you well. My better half, MIKE (that's
meeee!) K4HBI, and I just returned from a wonderful
mini-vacation in North Carolina, where we attended a terrific
Hamfest in Ashville. Isn't it amazing how you can go to a Hamfest
just about anywhere and run into a bunch of people that you know?!?
They say that it's a small world, but in amateur radio, truer words
were never spoken.
You won't have to go out of state to find a Hamfest this month,
although I do hope many of you will be able to attend the Huntsville
fest this year. As the ARRL National Convention, there'll be a huge
attendance, and well worth the trip. But, the Ellijay Hamfest is
coming up right around the corner, on the 11th of August. They claim
the title of the "biggest little Hamfest in Georgia", and guess
what? It's FREE. What more can you ask? It's a great opportunity to
escape to the cool Georgia mountains and enjoy a terrific day with a
bunch of other hams. Everyone has a chance to win one of the ARRL
books, and for the measly cost of one dollar per ticket, (with price
breaks on larger amounts) you can also buy yourself a chance at
winning one of their grand prizes, an ICOM IC-208H dual-band mobile
rig or a Yaesu VX-2R. Hope to see you there, but get there early.
Mornings must start earlier in the mountains, because it starts at
7.

Just in case you're the lucky winner of that VX-2R, it just so
happens that there's an article in this newsletter, written by
ED CRAVEY, KF4HPY, on how you can turn that little
radio into a "powerhouse". And since we all know that "two Eds are
better than one", there is also another article in this newsletter
written by Ed, about Yagis. These articles originally appeared in
the Lanierland ARC newsletter, and Ed was kind enough to let me
share them with you. (Thanks, Ed)
Hmmmm, I wonder which SE Division Director of Vice landed himself a
**starring** role in a play? That's right, our own SANDY
DONAHUE, W4RU, just began rehearsals for the play "Everyone
Loves Opal", which was first performed on Broadway in 1961. (Do ya
think he'll get to sing and dance??)The Opus Nostrum Dinner Theatre
productions of this play will be on Fridays and Saturdays from
September 14-29. Sandy says that his role is that of a con artist.
(No smart remarks!) Best wishes to him. Think he'll still remember
us when he makes it big...??
OK, folks, let's see what's been going on and what's coming up right
around the corner...
I was told to
be accurate, be brief, and then be seated. So I promise I shall be
as brief as possible,
no matter how long it takes me. WILLARD PEARSON
CLUB NEWS
It's always a pleasure to
share news about what all of our clubs around the state are doing.
(But y'all have to share it with me first...)
CHEROKEE CAPITAL ARS
--- Word has it that the communications provided by club members for
the Unity Runs in past years has "spoiled" the local police and
organizers of this annual United Way event, who have already
solicited the club's support for this year's runs, coming up on
August 28. Club president FELTON FLOYD, AF4DN,
reports that an email he received from the Executive Director of
Gordon county's United Way shows that their group "has made an
impact on the community". And it's been a positive one. Club members
will once again be supporting this event, providing them with the
opportunity to provide public service, as well as gain good network
and emergency communications training. As Felton noted, "Emergency
and public service events like these are the true backbone of
Amateur Radio."
FAYETTE COUNTY ARC ---
Club president BRIAN HAREN, W8BYH, wanted to share
some information about the club's repeater changes. He wrote: "In
the past month we've had some significant changes here in Fayette
County. For a number of reasons we had to dismantle our 190' tower
that carried our flagship KK4GQ repeater (145.210). The repeater
'went dark' on 21 June and the tower came down on 22 June (FYI, it
was Loudoun Communications of Douglasville that did the dismantling,
and they did a great job). On 23 June (Field Day) we were able to
reestablish the KK4GQ repeater (same frequency, offset and PL tone)
atop the Piedmont Fayette Hospital in Fayetteville. Unfortunately
the hospital sits in a low spot and coverage is not nearly as good
as it was atop our old tower. The good news is that the hospital
location is only a temporary home and we are in active negotiations
with several government agencies to place the repeater on a tower in
Fayette County that offers much better coverage. Hopefully in the
next few months we'll have things ironed out and the 145.210
repeater will be back as strong (or stronger!) than ever."
GWINNETT ARS --- For
the July meeting, FEMA employee WILL PERKINS, W1ZRV,
did a terrific presentation on family emergency preparedness. Coming
up at the August 14 meeting, PAUL PESCITELLI, K4UJ,
will wow members with his presentation on the Scarborough Reef DX-pedition.
All are invited. See www.gars.org for directions to the meeting
place.
MILLEDGEVILLE ARC ---
It was a real pleasure to visit with these folks at their July
meeting, and to present them with their brand spanking new charter
of ARRL affiliation. Interestingly enough, club VP CHARLES
PENNINGTON, K4GK, had another charter of ARRL affiliation
with him, which was presented to the club in 1974. Back in those
days, there were only four club members, and dues were a whopping
$2.50 per year. (As you may know, "once an affiliated club, always
an affiliated club"... but the difference is, the club went by a
different name back in those days.) Anyway, club membership has
grown tremendously over the years, now boasts members from many
counties, and as expected, dues have gone up just a tad. It was a
true pleasure to be with this terrific group, and to present them
with that new charter of affiliation. It was also a pleasure, and
well worth the trip, to hear the presentation of HARVEY
CHASE, W4TG, on HF operations. Harvey has been licensed
since 1931, so he brings a tremendous amount of knowledge and
experience to any discussion. (He doesn't just know about the
history... he's LIVED it!) CHARLES KIGHT, AI4UN,
also spoke briefly about his recent experiences at the ARRL's
Teachers' Institute. To say that he was brimming with enthusiasm
would be a huge understatement, and you can find his report later on
in this newsletter. Charles will also be doing a more in-depth
presentation on the things he learned at this fantastic seminar for
the club's November meeting, and he and the club are extending a
special open invitation to any teacher who would like to attend.
NORTH FULTON ARL ---
Sure hated to miss this club's July meeting, because their program
sounded like a great one. They held a QSL party, of sorts, where
each member was asked to bring some of their favorite QSL cards for
show and tell. Activities like this are a terrific way to show new
hams how much fun it is to exchange cards with other hams all over
the world. Only hard part would be in deciding which card is our
"favorite". (Which one would YOU pick??)

Fayette/AG4ZR:
Miscellaneous time - various work activities and meetings involving
the take-down of repeater system, tower, re-install of repeater at
hospital, PTC City Hall, and meeting with State personnel
negotiating potential tower location.
Morgan/K2MGL: Attended
Piedmont ARES Breakfast meeting (2 hours, Meeting at Morgan County
Em. Preparedness.
Effingham/KD6RYQ: We
started running SkyWarn nets every Tuesday at 9 p.m. beginning in
June on the 146.970 repeater and had over 60 stations check in this
month. The 146.745 Springfield repeater went down due to overheating
issues and we are awaiting a replacement. I met with Val Ashcraft
(Effingham EMA Director) and gained very positive feedback and
resources from his office. The Effingham ARES will train and meet at
SubStation #2 located at the intersection of Hwy 17 and Blue Jay Rd.
The organization has also been authorized use of an old telephone
microwave tower on the corner of Hwy 30 and Hwy 17 which will likely
house a new digipeater in the near future. I've been populating the
new database with member information as I receive it and it seems to
be working out well. Some Chatham area ARES members have shown
interest in training with our group during EmComm exercises and
classes and we hope that participation increases as a result. A
couple of Effingham ARES members participated in Field Day with the
Amateur Radio Club of Savannah (ARCS) and gained valuable emergency
operation training.
Clarke/N4ZRA: Clarke
Co. ARES conducted a SkyWarn Drill on June 2. The drill revealed
some necessary changes in the SkyWarn procedures and the report can
be found at n4zra.com Training Nets included the hotwash for the
SkyWarn Drill, a study of best practices for ARES, preparation for
Field Day, and a Field Day hotwash. Clarke Co. ARES also assisted
with the Great Day of Service 5K. Communications were provided by
KE4JLL, KG4WGZ, KG3WHA, KF4AQO, WB9TBY, and N4ZRA. The Clarke Co.
ARES members took part in three separate Field Day events due to
restrictions on the number of operators allowed at the 2 EOC
locations. Filed Day was conducted at the Georgia Public Health
District 10 EOC (N4NFI, KG4WGZ), the East Georgia Chapter Red Cross
EOC (KG4EYK, KI4PQU, N4ZRA), and at the AthensAirport (KJ4EX, AC4SH,
KF4AQO, KE4SPQ, WA4UET, N4JJM, N4ALE, NO9E, AG4ES). Four University

TURN YOUR VX-2R
INTO A POWERHOUSE
by ED CRAVEY,
KF4HPY
How many of you know and love your little Yaesu VX-2R for the vest
pocket treasure it is? Do you enjoy the AM and FM bands while
waiting for the bus or catching up on world events on the SW bands?
Or are you of the opinion that this radio is a weak excuse for an
HT. You are probably right; the radio transmit output is only 1.5W
on 2m and 1W on 70cm. This is the Hi-power setting for the VX-2R
with its 3.7V lithium-ion battery. This is barely enough for a
6-mile simplex contact over ideal ground. So what must be done to
improve the radio? The first thought coming to mind is, add an
amplifier, too expensive unless you already have one. Better rubber
duck antennas? Good idea, but not quite enough. How about doubling
the power? Put fire in the wire! Yes! Let's do it to it!
How are we going to do it without entering the innards of this
miniature radio? Did you read the specs in the manual? Well, it says
with 6V external power, the output on 2m is 3W and 2W on 70cm.
Double the power, 3dB gain; interesting, but is it going to break
the bank? Guess what, all the stuff is at RadioShack; yes,
RadioShack here in town. I would like to start with a parts break
down.
First we need a plug to insert into the radio. The manual doesn't
tell, but it is 2.3mm O.D. x .7mm I.D. in size. This is the "A"
adapter plug RS#273-1704. Next we need a power cord with the socket
on the ends to accept the plug. I favor the 6-foot (1.82m) "Adaptaplug"
power cord with female sockets each end RS#273-1740. Normally I cut
these cords in half for a belt pack, which is OK for my smaller
size. The other half can be saved for a future project. We have our
plug and power cord, next is the actual battery pack itself. I favor
the "D" cell 4-pack RS#270-389 as it is compact and can be assembled
back to back with another RS#270-389 and wired in series for 12V
use. To use the pack, clip the wires at the riveted contacts, and
pass 6-32x1/2" machine screws with washers through the grommet-like
rivets. These screws will be your terminals. Crimp the proper size
ring terminals to the power cord. The power cord Positive lead is
black/with with white trace. Negative is black. Secure the power
cord with washers, lock washers or locknuts to the screws. Insert
batteries (4) and we have completed the basic battery pack.
Some notes on this assembly: the pack terminals are exposed and if
the plug sleeve touches the positive terminal screw; arcs and sparks
are the result. Tape over the terminals as a precaution. A belt
pouch would take care of the safety factor and have a nice
appearance. If a smaller pack is desired use a similar pack for "C"
cells instead. One operating precaution: The finals in this radio
running 6V in a continuous duty cycle as in a net control ragchew
would not last too long. The same could be said for most HT's. So
keep the duty cycle reasonable, two minutes transmit, two minutes
receive or rest, a 50% duty cycle. The steps we have taken to add a
battery pack of "D' cells has doubled the output on 2m and 70cm to
3W and 2W on high power (H/L) and even the low power setting (H/L)
has increased from .1W to .3W on both bands.
You can make up battery packs for any radio by combing cases to use
common "D" or "C" cells of disposable or rechargeable batteries.
Remember 8 Alkaline cells equal 12V, but 8 Ni-cad cells equal only
9.6V. I will list some "Adaptaplugs" for various radios including
Yaesu FT 817, Alinco HT's, and even a printer.
FT-817: plug "B" RS#273-1705
Alinco HT's: "I" RS#273-1712
Canon BJC printer: "D" RS#273-1707
Short pigtail lead (4") RS#273-1743
This is a good way to allow any radio to become a base station. With
an outdoor antenna, and a power supply or battery pack of the proper
voltage. Great stuff for disaster relief people, as often recharging
is not practical. I can just see my VX-2R, with a varnished wooden
plaque, a Strong-tie FB24Z bracket, and my power pack bolted down to
form a power pack/stand, in league with a speaker mike and discone
antenna. An art form in small scale; a mini-powerhouse for those who
love Benvenuto Cellini miniatures.

MORRIS, WA4PZD
ANTENNAS AND YAGIS
by ED CRAVEY, KF4HPY
Once upon a time in faraway Japan in the 1920's at a university,
Professor Hidetsugu Yagi and his cohort Uda, took a simple dipole
driven element and added elements either in the front or rear along
the length of a boom. Using voltmeters and ammeters at various
points on the boom and elements, they found current changes
occurring in the antenna when the added elements were moved along
the boom or the length and placement was varied.
Each element added to a Yagi boom is not connected to the driven
element, which is normally isolated. Such added elements are called
parasitic elements and are mutually coupled to all the other
parasitic elements and to the driven element. Yagi and Uda found
that placing an element longer than the driven element behind the
driving dipole at a certain spacing would reinforce the original
radio wave during receive or transmit. What is taking place? The
parasitic elements, depending on length and spacing on the boom
reradiate the signal. These parasitic elements are called reflectors
or directors when placed in front of, or behind the dipole. Let's
look at a pair of two-element Yagis.
Take the parasitic element longer than the dipole and place it
behind the dipole, calling it a Reflector. Key the transmitter and
send a radio wave to the dipole which will radiate toward the
distant radio station and toward the reflector; the reflector will
reradiate back to the dipole and reinforce the outgoing radio wave
toward the distant radio station. How much reinforcement in this out
going radio wave? The max theoretical gain for a two-element Yagi
antenna is 5 dBi (3 dBd real world gain).
Take the parasitic element shorter than the dipole and place it in
front of the dipole, calling it a Director. Key the transmitter and
the dipole radiates toward the director and weakly to the rear; the
director reradiates the radio wave back to the dipole reinforcing
the signal going out toward the director and distant radio station.
The gain is the same as for the Yagi using the reflector as outlined
in the Antenna Handbook. These gains are achieved at a spacing of
.10 to .15 of a wavelength for the two-element beam using a
reflector. The two-element beam using a director is spaced at .15 of
a wavelength from the driven element.
Since the two-element beam has a gain of double the dipole, there
has to be a loss because you can't get something for nothing. The
response to the rear of the antenna is 10 dBi less than the forward
response. This is called front to back ratio and is what makes the
Yagi antenna directional. Gain in one direction and attenuation to
unwanted signals in the other direction. Feedpoint resistance: on a
dipole 72 Ohms, on a Yagi the resistance is reduced to around 20
Ohms.
The three-element Yagi has a reflector behind the driven dipole
element and a director in front, all doing the same jobs as
described earlier. The theoretical gain is now 7.28 dBi (5.13 dBd
real world gain). The front to back ratio is now 24 dBi with three
elements. The basic commercial Yagi beam is a three-element beam
with a boom of .45 to a .3 wavelength in length, with the longer
boom antenna having the greater gain. Adding directors to the
three-element Yagi increases the gain by 1 dBi per director.
Some of you may disagree with the gain figures of the completed
antennas. These figures are from the ARRL Antenna Book. If you read
older antenna books published before the age of the personal
computer, those books came up with slightly higher gain figures.
Even within the ARRL Antenna Book there is disagreement.
Getting back to Professor Yagi and Mr. Uda; Yagi introduced the beam
antenna now bearing his name to the world through his writings in
English. The design was applied to shortwave broadcasting about
1928. By 1935 the amateur radio world was reading an article in QST
by M.P. Mims, W5BDB, for a two-element 20m rotary Yagi beam. By
1938, Mims' Yagi rotary beam had set the trend for 10m beams. Moving
forward in time, I have some aircraft books showing the WWII
Messerschmitt 110 G-4 "NachtJager" (Night Hunter) with upward firing
cannon, and Yagi arrays on the nose of the aircraft for the
Lichtenstein Radar. The arrays were called "Hirschgeweih" (Stag's
Antlers). I have read accounts of these "NachtJager" fighters over
the Reich hunting the huge 4-engined RAF Lancaster bombers in pitch-
blackness. Chilling! After the war when aluminum tubing became
common, Yagi antennas appeared from 40m to UHF at ham stations. On
the consumer market, TV antennas for far fringe use were, in the
main Yagi antennas. Professor Yagi, in Japan was treated like a war
criminal, no messing with radios etc. per an article in QST during
the 50's. I remember the opening line of the article: "Doko Ni Yagi
San?" (Where is Mr. Yagi?). Imagine, unknown in 1926, published and
recognized in 1928 and a bad guy by 1946.
My own experience with Yagi antennas has been limited mainly to
rotary 6m and 2m beams with booms of wood, and copper elements. As a
budding Technician on 6m, my first dipole of wood, and threaded-rod
elements, was a wondrous item showing bi-directional traits. Next it
was building my own two element beam using treated wood 2x2's and
copper plumbing pipe; magic stuff, talk of gain, wow! I used the
dimensions provided by Ken Neubeck, WB2AMU, from his book: "Six
Meters, A Guide to the Magic Band". The reflector was 120", the
driven element was 112" cut into two pieces as was the reflector,
because I favor staggered elements for portable use. The boom
spacing was 48" between the elements. Performance was very good, and
stayed on the antenna farm until the MFJ 6m three-element Yagi
entered the market. Other two-element Yagi antennas I have assembled
were for 2m, with a spacing of .2 of a wavelength for 50 Ohm
matching to be used for emergency use. From my youth, Yagi arrays
have indicated DX transmissions, and far fringe TV reception. How
about you??
Two antennas
got married. The wedding wasn't much, but they had a great
reception.
TEACHERS INSTITUTE
CHARLES KIGHT, AI4UN, recently attended the
Teachers Institute held in Spokane, Washington. At these seminars,
teachers are provided with the tools to excite their students about
the marvels of science and technology. Charles was kind enough to
share with us the report that he made at the July Milledgeville ARC
meeting:
During the last week of June, I was privileged to attend one of 4
Teachers Institute sessions presented by the ARRL this summer. Due
to the hands-on nature of the Teachers Institutes, each session was
limited to 12 participants. At my session, I was one of only two
students from the Southeast. Applications were accepted on a first
come basis, and you didn't have to be a ham to be accepted. The
participants at my session taught a variety of grade levels from
Kindergarten though community college and about half were
hams--there was something for everyone. All of our expenses were
reimbursed, and we were each given several hundred dollars worth of
books and electronic materials that we can use in the classroom.
The Education & Technology Program is the only ARRL program funded
entirely by contributions! The Teachers Institutes are part of this
program. The goal of the Teachers Institute program is to teach
teachers about wireless technology and inspire them to incorporate
it into their lessons. According to Mary Hobart, ARRL's Chief
Development Officer, "This program is among - if not THE - most
effective ARRL has been able to mount in recent years."
The Teachers Institutes are taught by Mark Spencer, the Education &
Technology Program Coordinator for the ARRL. Mark is an inspiring,
engaging, and entertaining teacher, and I have to say that this was
the best experience that I have ever had as a student. A variety of
basic topics were covered during the 4 days of our training
including: wireless technology, electronics, and radio science;
satellite communication; ham radio operation; micro controllers; and
robotics. I had a great time, learned a lot, and enthusiastically
recommend this program to any teacher who wants to incorporate
technology into the classroom. I am planning to give a more in-depth
presentation at the meeting on November 17, so if you know of anyone
interested, particularly if they are teachers or students, please
encourage them to attend.
Now I'd like to show you a couple of things that we did in class.
Electromagnetism Demo
Simple Robot Demo using BASIC Stamp Micro-controller
(NOTE: Can't "show" you the demos he did, but they were cool!)
The only thing wrong with
the younger generation is that most of us aren't in it.
SOME LEGAL ADVICE
COOPER MORRIS,
WA4PZD, one of our Volunteer Counselors, has shared the
following information for your consideration:
A County in North Georgia has made threats to an amateur radio
operator in hopes of shutting down his station to resolve complaints
from a neighboring sub-division's homeowners. Mind that the
homeowners (3 to be exact) have presented no evidence, just made the
allegations. At no time did the homeowners allege interference. Only
the antennas look bad and could cause health problems to their young
children.
The County in question has a good tower ordinance respecting amateur
radio towers and the sub-division the amateur radio operator lives
in has no CC-R's to consider. So some enterprising individual came
up with this avenue of attack.
The complaining homeowners have used the same argument used against
Georgia Power High Voltage Transmission lines and cell telephone
towers. Electric and Magnetic fields and the attendant RF field
strength.
We presented evidence that the amateur radio question station in
question completely complies with FCC Bulletin OET-65 (B). Which, by
the way, the County personnel did not know existed. Nor did they
understand it when presented to them. The ball was put in play in
their territory to dis-prove the submitted evidence. So far no
further contact with the County personnel respecting the complaint
against the amateur radio operator.
I strongly suggest that you go to:
http://www.qsl.net/w0jec/index.html (or whatever program you
have to do the calculations) and run the necessary calculations for
your station and PRINT them off. Keep them around until need to you
change antennas, feed lines, or add and amplifier.
I suggest that calculations for three different frequencies in each
band you operate on be run.
Any questions or comments let me know.

THIS 'N' THAT
*** The Hall county VE
team will be holding their August 5th session in a different
location. For this month only, the session will be held at the
Flowery Branch Masonic Lodge, located at the intersection of Spring
Street and Gainesville Street in Flowery Branch, GA beginning at
2:00PM. (de ALFRED WESTBROOK, KT4VP)
*** IMCC wants YOU!! All of you avid CW operators, take note! (and
you phone operators, too) IMCC, International Morse Code Contests,
Inc, is setting up a special event station at the Grove Park Inn, in
Asheville, NC, on August 18 and 19, and operators are urgently
needed to help with this... maybe you? This special event station
will be celebrating the Morse Code world record that was set in
Asheville back in 1939, and they're also setting the stage for a
live Morse Code speed contest, which will be held in Asheville in
August of next year. Ten-Tec is providing a couple of Omni-VI rigs
for use for this special event station, and CW and phone operators
are being urged to volunteer. The call sign used will be W1MCW. To
volunteer your services to help them work the pile-ups, send an
email to 2007se@w1mcw.org or
check www.w1mcw.org for more info
on this event, as well as next year's high speed competition. Their
goal is to break the record next year. Think you got what it takes?
*** Last month, I asked for input on the history of the Atlanta ARC
Hamfest. I didn't get any response on that front, but ROBIN
CUTSHAW, AA4RC, sent along a terrific URL with some
interesting radio history, including some on the Atlanta club. Once
upon a time, the Radio Service Bulletin was issued monthly by the
Bureau of Navigation, Department of Commerce, and included on this
website is a letter that was included in the April, 1916 issue. It
was written by FRANCIS F. MERRIAM, who was the president of the
Atlanta Arc at that time. Very interesting reading, and a terrific
website for all of you history buffs.

THIGPEN, W4IS. It is chock full of information about mike

*** To eliminate the D-Star noise that's been causing such a problem
on the Pine Mountain 145.190- repeater, the repeater now has a PL
tone of 123.
*** And your neighbors think YOU have a big antenna! Many of you
remember hearing the signals that used to come out of Russia that
hams "lovingly" called the "woodpecker". During the 60s and 70s,
this over the horizon radar, which was aimed over the north pole to
watch for any US missile launches, made quite a racket on the ham
bands. Now, here's your chance to take a look at the antenna that
was used, which was fed by several 75 KW transmitters:
