A note from the coordinator...
Why amateur radio? That was one of the questions during an interview this week
with Carl Belnap of the Talking Voice. (712-432-6499 Press four pound. Then
press two pound. Then press nine pound for the first half and ten pound for the
other half.) Ham radio communications differ from other methods because ham
radio operators understand and apply the science and technology that underpins
the hobby. That allows hams the ability to creatively solve the problems that
impact their capacity to communicate, something that is not available when
simply using Skype or a cell phone. If a person just wants to communicate,
plenty of methods are available that don't require a license. If, however, a
person wants to develop their skills in the areas of science, technology,
engineering, and math, ham radio is the perfect hobby.
Luther Washington found the challenge of amateur radio to be just what he
needed. His story was printed in the Summer 1993 issue of Handiham World:
A new perspective with Handihams
To Luther Washington, an active CB'er, radio was an almost unlimited hobby. It
seemed to him that one could never exhaust the fun of getting on the 11-meter
band and meeting other folks. But in 1980, a serious back injury at work left
Luther with time on his hands. Unable to return to work, he soon realized that
he had already plumbed the depths of the CB world, and there wasn't much left
Still, as he continued his physical therapy, his strong interest in radio
remained, and he was drawn to a hamfest where Handiham Educational Coordinator
Sister Alverna, WA0SGJ, was handing out literature at the door. Sister told him
about the wide horizons of Amateur radio, the licensing requirements, and the
services the Handiham Program could extend to him. It all seemed so much more
exciting than CB!
Maureen Pranghofer, KF0I, then Handiham Student Coordinator, invited Luther to
visit Courage Center for a look at the headquarters station, W0ZSW. It was
amazing! Maureen explained how the equipment could be used to contact stations
around the world, about the different modes of operation, about the QSL cards
on the wall, and-most importantly-how the Program could help him achieve his
Amateur Radio goals! Unable to resist the challenge, Luther "joined up," and
soon his days of therapy were no longer boring because he had something new to
work toward, his "ticket"! Besides, he recalls, "My XYL, Mertha, didn't like
the CB. 'That thing has GOT to go!' she said."
Luther studied with the tapes, and Tony Tretter's voice became as familiar as
that of an old friend. Maureen was his one-to-one helper, and he attended
classes given by another Handiham member. Soon, he passed his Novice test and
got on the air with a Tempo One. He worked his way through the license manuals,
one by one, advancing through the "ranks".
"Why don't you go to Radio Camp?" suggested Dave Block, KA0VCW.
That was good advice! Radio camps were a big help! Luther attended three Fall
Radio Camps at Courage North in Minnesota. He studied for and passed his
General, Advanced, and Extra, working at home in preparation for camp, and then
harder than ever during the weeks of camp.
It takes more than passing exams to be a ham, though. It takes a station, and a
lot of hard work to set it up. That's where Dave Michael, WA0CTZ, stepped in to
help. Dave put up Luther's tower. Greg, Luther's son, is the designated tower
climber. Greg has climbed the tower again and again, and worked on the "shack"
as well. And while Luther may have great helpers, he dives into the ham radio
projects that he can do by himself, even building traps and winding the balun
for his own antenna!
Luther operates with a Kenwood 440, though he still has the Tempo. His favorite
modes are HF SSB and two meter FM, and he can usually be found on 3.925 MHz,
7.248 MHz, 14.295 MHz, and the Handiham nets. He emphasizes that it doesn't
take an awful lot of money to get started in Amateur Radio, and even though he
now has the Kenwood and a growing collection of antennas, the Tempo only cost
him $150, and he used his existing CB antenna on 10 meters.
Says Luther, "The Courage Handiham Program helped me to gain a new perspective
when life just seemed to have no direction. I was limited in my ability to move
around and to meet people. More Handiham members should be able to visit
headquarters and meet the people I have worked with personally. They are

beyond simply keying the mic. Do you have a story to share about your ham radio

The amateur radio story of Tom Lykins K4LID
My interest in radio began in 1958 when I was six-years-old. Prior to that, I
wanted to drive race cars as my oldest brother did at Kilkare Speedway in
Xenia, Ohio, and at the Clark County Fairgrounds in Springfield, Ohio.
Although I knew I was blind, I could not correlate why I could not drive a car.
My brother tried to explain it to me, and it finally sunk in to my mind.
What, if anything could I do for a hobby or recreation? I had always listened
to the radio and started playing with the dial. At that time we didn't have an
FM radio or shortwave, just AM.
One of our local stations at the time (WBLY) operated on 1600 KHZ. This was at
the top of the band, so it was easy to find. I knew if I tuned the dial past
that end, it would stop. Being a young child, I forced the dial past the stop
and broke the dial cord. After my Mom and sometimes my Dad would restring it, I
would start again.
Beginning in 1959, my favorite radio station was WING, which operated at 1410
on the dial. I could not understand why, at sunset, I could no longer hear
them. Why did they have to do this? As a result, I would cry and cry like
someone had passed away.
It was worse for me when I had to leave home and go to school at the Ohio State
School for the Blind, about fifty miles away. It was more difficult to listen
to WING, and I had to listen in the day when I could but was stuck with WCOL in
Beginning in 1960, I had enough. Something had to be done. So, I decided to
memorize the radio dial which I have done since, regardless of where I lived or
was, even on a temporary basis. It took a while, and I didn't understand about
propagation and why things were the way they were on Medium Wave (AM), which is
the standard broadcast band.
There would be times when I would listen for WING at night and in the daytime
listen to WIZE, another local station in Springfield. However, listening to
WBLY was a challenge as there was a Columbus station at 1580 KHZ on the dial
which was WVKO. Their transmitter was on Henderson Road, about two miles from
the school. Obviously, they wiped out WBLY unless you had a commercial grade
tuner or receiver, which I did not have.
During this time at OSSB, a class was started for Ham radio. "CARA" The
Columbus Amateur radio club had two hams who came to the school and offered
classes. For some reason, you had to be in the 5th grade to take them. Their
emphasis was learning the code and then theory for the Novice Class license.
In the meantime, I heard about shortwave radio from a friend. I asked for a
shortwave radio for Christmas and received an 8 Transistor AM/shortwave radio
for Christmas in 1961. The radio covered the 41-meter band. In addition to
various broadcasts from The Voice of America, WRUL in New York, Radio Moscow
and Cuba, I heard what are known as utility stations and amateur radio
At that time, I had no conception of what Single Sideband sounded like and was
not sure about CW (Morse code). In 1962, I soon learned from other students at
OSSB the difference.
My father, who worked at the former Ohio Steele Foundry, said that there were
some hams who worked with him. In looking back, he was confused between Ham
radio and CB radio. It should be noted that CB radio started in 1958. My Dad
said that as a "Ham Radio Operator," I could talk with world leaders and that
was how meetings between various countries were held. I learned this was not
At the School for the blind in Columbus, we had an amateur radio club station.
The call sign was WA8BAR. Our rig was two homebrew crystal controlled
transmitters for 80 and 40 meters and a Collins 75-A3 receiver donated by CARA.
Unfortunately, we did not get much time on the air for those who were licensed.
In September of 1965, a new industrial arts teacher came to OSSB. His name was
Starling Hutt with the call sign of W8QEM. He quickly learned from some of the
older students that they were interested in amateur radio and, for him, not
being familiar with teaching blind boys how to develop their manual dexterity,
he saw an easy out. He proposed that all of us study for our Novice license and
get our tickets. This was in the fall of 1965.
I had a terrible time learning the code. So, another friend said the quick way
to learn it was to tell dirty jokes and to curse people out using the code and
be as profane as possible. Instantly, I learned it overnight, along with those
around me. We were going around school using profane words and the most
debasing conversations you could have.
In December of 1965, I passed my code test. It should be noted that in those
days, you had to take a sending test as well. My test for my written came in
the mail to Mr. Hutt, our instructor, and on a cold snowy Monday afternoon in
January of 1966, I took my test along with others in the class.
Most of us failed. This was because the tests we had been sent were different
from the ARRL questions we had been studying. When Mr. Hutt gave me my score,
he said. "Lykins, you did stinkin."
I was totally disheartened. Another reason was that there were no solid state
rigs at the time. You had to load and tune your transmitter which I knew would
be a problem for me.
Later that winter, I, along with another student, were called into the
Principal's office. He started sending CW back to us. We were caught! No more
cursing people openly with CW. However, we would still do it discretely.
I took my Novice test again in April of 1966 and passed. Now, how was I going
to get on the air? When I would go home on weekends, there was a ham who gave
classes in code and theory every Friday evening. His name was Paul Crowell,
W8WXG. He had a big table in his home with a code key at every place fed into a
Morse code oscillator, and we would send and receive the code.
In April of 66, Mom and I along with another friend, Jim Hill, went to Custom
electronics in Dayton. They were on Brown Street next to NCR (National Cash
Register Company). There, Mom bought a Hammarlund HQ110 for me. Now, I needed a
transmitter, key, and crystals for the novice band. In Springfield, we had a
Lafayette Radio store on Belmont Avenue operated by Joe Elliott, W8VZM. He had
a Heath DX-20 transmitter for sale for $35. Mom bought it, and Paul Crowell
gave me a key. Mr. Hutt found a place in Florida where you could buy Jan
Crystals for $1 per crystal. Mom bought for me all of the crystals for 80, 40,
and 15 meters where Novices had privileges to operate. Now, to put up an
While all of this was going on, I was big into CB. In Clark County, we had a
Junior CB Club. We would meet at the Moorefield Township Fire Department or the
Carpenters Hall in Springfield. I had a friend, Butch Phillips who said he
would put up a 40 meter antenna for me. While his heart was in the right place,
we didn't have the right material to put up a proper antenna.
So, on August 30, 1966, we fired up the DX-20. Remember, I didn't know how to
tune it and, as a consequence, "smoked it." The stench was so bad that Mom
could not get rid of it for over a year. No matter how hard she tried, nothing
would work to eradicate that smell. By this time, I was totally discouraged
with Ham radio and said it was a lost cause.
But wait!!!!!!! There is more!
I moved to Louisa, Kentucky in 1972, and the first ham radio operator I met was
Elmer Tom Pigmon K4PGA. He was using the tube tester at Ern's Newsstand located
on Pike Street across from City Hall. Although I had not been active in Ham
radio since 1966, I still kept up with what was going on in the hobby. I then
met Leonard Compton, K4PFZ and his brother Jim Frank, W4ZVL. I would not meet
Fred Jones, WA4SWF until a couple of months later. Frankly, I was amazed that
Louisa had so many hams. Fred and I became fast friends and he told me about a
repeater that he and Elmer Tom wanted to put on the air.
At that time the Big Sandy Amateur Radio club was formed. Our meetings were
held at City Hall and later at the original repeater building on Five Forks
Hill at the home of Charlie Fyffe, WD4LIP. I still was not really interested in
getting back into amateur radio.
There was a policeman at the time, Larry Sparks, who was interested. When we
would work together, I taught him the code. For practice, he would read
articles from the Big Sandy News and resend them in CW. He finally thought he
was ready to take his test. When he took the code test, administered by Fred
Jones, he passed. The FCC sent back two written tests instead of one. Fred
called and asked if I wanted to take the novice test. I said I really didn't
care, it was a bunch of junk and to forget it. But he persisted. He said that
he and Elmer Tom needed someone to monitor the repeater and that they could not
be there to do it all of the time. I had the perfect situation to do so. So, I
acquiesced and took the test. Needless to say, I passed with flying colors.
This was in January of 1978.
In March, I received my call sign, WD4RWU. Previously in Ohio my Novice call
sign was WN8TWH. Neither call sign was to my liking. I knew I had to upgrade to
Technician class to get on two meters and to use the repeater. So, back to the
books again. It was ironic that I passed my Technician class exam in December
of 1978, just before the major flood which almost wiped out the construction
dam in Johnson County. As a precaution, residents of Johnson County were
evacuated to Louisa. Fortunately, the dam did not collapse, but there was major
flood damage. The repeater was put on the air on September 4, 1978, which was
Fred, Elmer Tom, and I went to St. Albans, West Virginia, to the residence of
Don Rees, W4VQA, who built the repeater. We brought the repeater back and put
it on the air. It was a GE Proline with two Ringo Rangers for antennas.
Throughout the years since then, I have loved and enjoyed this hobby and the
friendships I have made. No tongue can tell what this has meant to me. Like the
author of Tennyson's brook, I could go on and on and on and on, but it is time
to bring this missive to a close.
Thank you, Fred Jones, WA4SWF, for making it happen for me, not only on two
meters, but also HF and the Kentucky Nets. Fred introduced me to the National
Traffic System in February of 1978. I have been hooked ever since.
Times have changed, and people have come and gone, but I will always remember
my roots, not only in Ham radio but in radio in general. Thanks to all who
helped make it happen for me. I have held an advanced class license since 1995.
Since that time, the license structure has changed. No longer is there a Novice
or Advanced Class license. Those of us who have these classes of license can
retain them as long as we like, so long as we renew them. My involvement with
the Handiham program began when I was into NTS Nets. Judy Mortinson, WB0WNJ,
along with Sister Alverna, would send out radiograms to all Handiham members.
As part of the Kentucky Traffic net and the Daytime 9th region phone net, I
would pass and relay traffic. Sad to say, Judy wound up in a nursing home and
later became an SK.
I think that the Handiham system is definitely a worthwhile program, but we
need to find a way to get more local hams involved. This is generally where
"mentoring" starts, from the local level. Thanks for allowing me to post my

Ham Radio 2017 was Great
By Ken Silberman (KB3LLA) and Christoph Bungard (DF9WM/KB3PRN).
Ham Radio, the biggest ham fest in Europe, was held from Friday, July 14,
through Sunday, July 16, in Friedrichshafen, Germany. The ham fest was put on
by the German Amateur Radio Club (DARC).
The Handiham Program shared a booth with the Interest Group of Blind and
Visually Impaired Hams in Germany (IbFD). Handiham members Christoph Bungard
(DF9WM/KB3PRN) and Ken Silberman (KB3LLA), as well as a number of other blind
and sighted German hams, handed out literature for the Handiham and IbFD
programs and talked about both to visitors. We also demonstrated accessible
radios, EchoLink, and the Handiham remote base.
There were frequent interactions with visitors as we assisted with the
scavenger hunt that the DARC had organized for children and young adults. At
our booth, participants were given a piece of paper with a word in Braille
written on it which they had to decipher by using a Braille alphabet.
In addition to being a Handiham member, Christoph is also the president of
IbFD. So, this was truly an international effort! IbFD was very kind to have
invited Handihams to participate in the show for the second time in a row.
For blind and visually impaired hams, the highlight of the show was the RFinder
Android Radio. http://androidradio.rfinder.net/ It is both a cell phone and
an HT. Because it runs on Android, TalkBack works. Ken was able to select a
repeater from the RFinder database. There is currently a 440 version that is
both analogue and DMR. A two meter analogue version is supposed to come out
soon, without DMR. A dual-bander with DMR is supposed to come out next year.
All the usual venders were there too. We all got Yaesu hats and visited the
ARRL booth. We ate a lot of great German food and experienced wonderful German
Some of us participated in a VHF/UHF contest at Ham Radio. At the show, Ken
spoke with some dedicated CW operators. They showed him a small, old Russian
spy key, and a homemade key with a knife as the paddle. We also met Jean-Claude
Heim (F6IRS), vice-president and secretary of the French blind amateurs group
(UNARAF). One of the really cool highlights was a ham that went Zeppelin
mobile. Yep! He had QSOs from a blimp.
This year's show is history, but we are already talking about possibly meeting
again next year at Ham Radio in Germany or at the Dayton Hamvention in the U.S.
Preparing for Your Amateur Radio License Exam
By: Dr. Ronald E. Milliman, K8HSY
If you are preparing to take your ham license exam, regardless of the license
class, Technician, General, or Extra class, here are some resources that can
help you prepare and pass the first time through.
These ham test preparation materials and resources are quite accessible and
available to blind and low-vision individuals who are seeking to become new
licensed hams or to up-grade to a higher license class. Some are free and some
have a modest charge, but they are all good.

Call to Action.
ARRL President Issues Call for Members to Reach Out to their Senators to
Support S. 1534
ARRL President Rick Roderick, K5UR, is calling on League members to urge their
US Senators to support the Amateur Radio Parity Act of 2017, S. 1534. ARRL has
opened a RallyCongress page to simplify the task.
"[W]e are at a crossroad in our efforts to obtain passage of The Amateur Radio
Parity Act," Roderick said. He said the campaign to secure passage of the bill
scored a major victory earlier this year when H.R. 555 passed unanimously in
the US House of Representatives. Obtaining passage of the companion Senate
bill, S. 1534, is the final legislative hurdle.
"Now is the time for all hams to get involved in the process!" Roderick said.
"Many of you already live in deed-restricted communities, and that number grows
He urged radio amateurs now restricted by a Homeowners Association from
installing effective outdoor antennas to visit the RallyCongress site and
e-mail their two US Senators. He also encouraged those not now affected by deed
covenants, conditions, and restrictions (CC&Rs) to support their fellow radio
amateurs by doing the same.
"If you want to help create an opportunity - not available before now - for
Amateurs who live in deed restricted communities to install effective outdoor
antennas on property that they own or lease, send these e-mails today!"
Roderick said. "We need you to reach out to your Senators today. Right away."
S. 1534 was introduced in the US Senate on July 12, marking another step
forward for this landmark legislation. Senators Roger Wicker (R-MS) and Richard
Blumenthal (D-CT) are the Senate sponsors. The measure will, for the first
time, guarantee all radio amateurs living in deed-restricted communities
governed by a Homeowners Association (HOA) or subject to any private land-use
regulations, the right to erect and maintain effective outdoor antennas at
their homes, while protecting the aesthetic concerns of HOAs.
STEM as an Equalizer
I remember as a child being amazed by a "transistor radio." It was Christmas
time, and I was probably no older than three. We came home and were about to
open presents; my mother handed me a package that was playing music! I was so
amazed! I scrambled to open the package and held in my two hands a radio that
wasn't plugged into anything. What I mean by that is that I had thought up
until that point that all radios needed to be plugged into an outlet. I
remember with great respect the outlet because I accidentally put one of my
fingers near one of the two prongs when I tried to plug in the radio and got a
big shock! Yet, this radio was playing music and didn't need any electricity
from an outlet. This started my fascination with everything electronic at a
young age. The radio that I held in my hand was a "Heathkit" radio with six
transistors. The "Heathkit" meant that it was purchased as a kit from a
renowned supplier of all things wonderful pertaining to electronics!
I remember thinking how amazed I was that I could tune a dial and hear
different radio stations. It was like they magically appeared. Later I would
build crystal radios which consisted of a coil of wire with an antenna inside;
and when one moved the antenna up and down a different radio station would play
through an earphone attached to the radio. The radio was very simple. There was
a coil of wire with an antenna, a small crystal with two wires attached to it,
and the earphone. No batteries were needed because the magnetic energy of the
radio wave was enough to power the sound through the earphone.
The various electronic parts such as tubes, transistors, and crystals became a
mainstay in my life that captured my interest.
Fast forward to 1967-1968, when I was met Ned Carmen, who asked me if I would
be interested in learning more about Ham Radio. As soon as I heard the word
"radio," I was all for it. Followed was an incredible experience of learning
radio theory, talking to other hams, and experiencing the wonders and mysteries
of radio waves!
One of the first questions I asked was "where are the Braille books that I can
read about Ham Radio"? I was told that there were lots of "blind hams", and
that all I need to do was reach out. I remember pouring over a magazine called
the "Braille Technical Press", which had all kinds of circuit descriptions
complete with full instructions in how to build them. I learned all about the
"base" "emitter" and the "collector" of a transistor. I learned about how
antennas are magnetic pickups that capture the magnetic flux of the radio waves
and generate very tiny voltages that can then be picked up by a receiver. I
learned that it isn't a good idea to grab hold of an open wire feeder line
feeding a long wire antenna through a match box when the transmitter is keyed!
I learned Morse code and passed both the code and theory test for the novice
license! I went on to pass the general license and continued my fascination
with all things scientific and radio!
For me, science and ham radio were absolutely one and the same. Ham radio
taught me about physics. Ham radio taught me about electricity. Ham radio
created the incentive for me to understand the mathematical equations for
reactance and inductance! Most importantly, ham radio taught me, a blind
person, Helen, a person who was in a wheel chair because of polio, the Sisters
of the convent of Assisi Heights, the IBM engineers of the Rochester Amateur
Radio club, the many others that were either blind, paraplegic, quadriplegic,
that we have an equalizer that bridges us together.
Now, fifty years later, the significance of science and all manner of
technology and mathematics (STEM) is more important than ever! STEM is the
great equalizer. Regardless of our disability--blind, paraplegic,
quadriplegic--we all have an equal chance in ham radio to learn science and
math in a practical setting. Our children can experience the wonderful world of
A strong Handiham organization is a key component of a strong STEM foundation
for all of us who want to embrace equality in the disabilities!!
No matter what our disability is, we have an equal chance!
Down memory lane...
In honor of the celebration of 50 years of the Handiham Program, here is an
article from our former coordinator, Pat Tice, WA0TDA, first printed in the
Winter 1995 issue of Handiham World.
Things technical: Small antennas revisited
A common complaint among Handiham members, many of whom live in apartments, is:
"Sure, I would like to get on the HF bands, but I can't have an outside
antenna." When I hear from members who have this problem, I first try to find
out if they've exhausted all possibilities for an outside system. For example,
a vertical antenna, ground-mounted, can be inconspicuous and take almost no
real estate. Some landlords won't mind a tidy installation to the rear of the
building. Hams living in mobile homes can sometimes install verticals disguised
as flagpoles, and no one is the wiser! A 20 meter vertical is about 16 feet
long.just right for a mobile home park! End-fed wires, running from a metal
balcony or counterpoised by aluminum siding, can be very effective and are
barely noticeable. You might be surprised to find out that the landlord may
allow you to install an antenna on the roof.You never know unless you ask!
Well, did you ask? You got turned down? Too bad, but it's not the end of your
HF career! Now you are free to concentrate on compact antennas that won't work
quite as well as their outdoor cousins, but will nonetheless allow you many
hours of enjoyable contacts on the shortwave bands. There are plenty of
ingenious antenna designs, but they usually fall into one of two groups: loops
Loop antennas can be impossibly tiny compared to a full-sized dipole, and that
means they can be made to fit almost anywhere. Commercial versions, such as the
MFJ "Super Hi-Q Lopp" (36 inches diameter) and the "Box Fan Portable Loop" (a
2X2 foot box the size of a fan) operate 10 to 30 MHz and 14 to 30 MHz
respectively, and will truly fit anywhere. As you might expect, the feedpoint
impedance of compact loops isn't very close to 50 Ohms; in fact, it may be on
the order of a fraction of an Ohm! If the conductor is not carefully designed,
and connections aren't perfect, RF loss can be enormous! A matching system is
essential, of course, and all units include one. The AEA Isoloop, which is
similar to the MFJ loop, is 35 inches in diameter and covers 10 to 30 MHz.
Commercial loop antennas of this type cost between $200 and $330.
If that's too rich for you, you might try your hand at homebrewing a multiband
loop, but this is not a project for the faint-of-heart! Great care must be
taken to avoid any sort of loss, and you must be prepared to construct a
suitable capacitor to be driven by a low speed gear-head motor. For a good
construction article, see "A Home-Brew Loop Tuning Capacitor" by Bill Jones,
KD7S, in the November, 1994 issue of QST. Coincidentally, the same issue
describes a compact loop for 80 meters in the Technical Correspondence column.
This design, by Dr. Jon Jones, NO0Y, is 7X9 feet, and is very inexpensive to
build. An advantage is that the capacitors are fixed value, so it is not
necessary to construct a motor-driven tuner. This, and most loop designs, will
not tolerate over about 100 Watts, but that's plenty to make many good contacts.
The other type of compact antenna, the wire antenna, is generally easier to
make, and can be up and running in a matter of minutes. The disadvantages,
compared to compact loops, are the need to provide multiple insulated supports
(at least one on each end) and the space requirement: more! Wire antennas can
be the standard dipole design for 20 through 10 meters and still be small
enough to fit into an apartment. Calculate a starting length by the formula:
468 divided by the frequency in MHz. A dipole for operation on 28.350 MHz would
then be: 468 divided by 28.350 = 16.51 feet. Sixteen and a half feet is a
manageable length, but 10 meters has not been very usable during the current
sunspot minimum, so for the more reliable 20 meter band: 468 divided by 14.2
MHz = 32.96 feet. Not too many apartments will accommodate a 33-foot antenna,
so it's time to start snaking the antenna around the room, making as many bends
as necessary to fit it in. Keep in mind that doing so will probably detune it
somewhat and that there will be some cut-and-try before you are satisfied. RF
voltage will be highest near the ends, so care should be taken to see that they
are insulated and away from metal pipes, ductwork, or trim.
Another design is the end-fed wire. The conductor is simply a random-length
wire strung around the room and fed with a tuner. The advantage of this wire
design is that it can be made to work on a variety of bands, unlike the dipole,
which works only on a single band. Disadvantages are the need for a tuner (the
ones built into most rigs won't do the job because they lack adequate range and
the need for a good ground against which to "work" the radiating element. A
ground may be rather difficult to find, because RF ground is quite different
from DC ground. A long wire running to a ground rod is usually not an
acceptable RF ground. A nifty little box (really a tuner) called the
"Artificial Ground" by MFJ can be used to make an otherwise useless wire into a
working approximation of "ground." With this, as with all tuners, be prepared
to take some time to learn the settings for various frequencies, and don't be
surprised if you have to change settings even for a relatively minor move up
the band. Watching the SWR bridge is crucial, so members who are blind need an
adapted SWR meter such as the one detailed in the July, 1994 QST magazine.
When you have your indoor antenna farm securely planted, there are a few basics
to remember. First, because you may be operating in an apartment where a
neighbor's turf is only inches from yours, RFI (Radio Frequency Interference)
or TVI (Television Interference) may be problems. While some problems can be
solved by assuring that your signal is as "clean" as it can be, a sad fact of
life is that typical consumer electronic items are easy prey for a strong RF
signal. The result will be unhappy neighbors who can't understand why they
should tolerate interference on their $10 telephones and plastic-encased
television sets. Secondly, because you will be operating near your antenna, you
will be sitting in an RF field. While no one really knows if high levels of RF
(at least at amateur frequencies) are harmful, it is prudent to limit exposure
by operating low power. This is good operating practice anyway, and it will
also serve to reduce or eliminate RFI and TVI. Finally, you must be prepared to
be flexible. When your transmitter is causing interference, you should limit
your hours of operation.
Small antennas, even when used indoors, can open the door to the excitement of
the shortwave bands. Give them a try!
What are you waiting for? Check into our Handiham nets... Everyone is welcome!
How to find the Handiham Net:
. The Handiham EchoLink conference is 494492. Connect via your iPhone, Android
phone, PC, or on a connected simplex node or repeater system in your area.
The Handiham Net will be on the air daily. If there is no net control station
on any scheduled net day, we will have a roundtable on the air get-together.
Our daily Echolink net continues to operate for anyone and everyone who wishes
to participate at 11:00 hours CST (Noon Eastern and 09:00 Pacific), as well as
Wednesday evenings at 19:00 hours CST (7 PM). If you calculate GMT, the time
difference is that GMT is five hours ahead of Minnesota time during the summer.
Doug, N6NFF, poses a trivia question in the first half of the Wednesday evening
session, so check in early if you want to take a guess. The answer to the
trivia question is generally given shortly after the half-hour mark. A big
