Our program this month will be Rol Anders K3RA who will discuss the set up
of the W3AO 29A Field Day Station this year.
JUNE MEETING MINUTES
ARC Meeting, 14 Jun 13
President, Tom, called meeting to order at 1900 at the Alexandria Police Hq
Conf Room
ARES Eric Parker, KG4DZA, with the Alexandria EMS provided a talk on the
Department of Emergency Communications. Generally, it is considered that
the City will be able to maintain communications for most of the situations
they would be facing. There is still a need for ham radio assistance but we
need to develop plans to address what activities the hams can be expected to
join public safety support. Arlington and Fairfax are considering including
ham radio with their public service CERT program. So far, Alexandria has
not joined that concept.
Field Day Jack/K5OZ reviewed the status of FD plans. The only action that
is still open is the food. He is planning on collecting food this week and
have our needs well satisfied by time of FD. We will be 5A. Try to keep
radios operating the full 24 hrs, 1400 1400 Local 22-23 June.
Whats Happening Doug Rose/AK4QY discussed some work he has been doing
using PIC chips. This has applications to APRS. ARRL has a publication
relative to this subject.
Repeaters 6 Mtr should be back on the air by end of summer. Needs
controller.
2 Mtr Some unknown issue is affecting the repeater. Appears to be related
to moisture. Wet is good, dry is bad.
D-Star appears to be working well.
Manassas was considered to be smaller that last year. Still a lot of
HR/Computer stuff. Tom/KJ4FUU, Club president presented the two plaques to
winners. One in person, other in abstention.
What can we do to increase new ham participation in weekly nets, use of
repeaters?
Antennas Consider developing a work session to build J-Pole antennas out
of twin lead. Harry will be lead on this effort. Possible at FD or as a
program for a meeting.
Operating Provide opportunities for nubies to operate at FD.
No other Old Business
New Business
Art Blank/WA7NB is going on an Expedition with several other hams to Robin
Caruso Island with plans to be operating between 6 and 21 Nov 2013. The
club will donate $300 to the operation (Rick proposed, Jack seconded,
passed)
Ham Radio Outlet and the ARC will be developing several radio packages
appropriate for the new ham to include various levels of capability, such as
an HT, Mag mount, cable; Dual band Mobile radio, power supply, cables, Mag
mount; HF set; etc. The point of this action is to help the new ham to get
necessary radio and support items at a reasonable price.

Ways & Means Ted auctioned off several items drastically needed by the
assembled hams.

FIELD DAY JACK K5OTZ
Field Day 2013
Jack Hranicky K5OTZ
This years Field Day was a success with 42 people signing in which was a
30% increase over last year. Saturdays weather was fine; however, Mother
Nature was not kind to us on Sunday with rain. This caused us to shut down
early. Propagation and the noise level made getting started Saturday slow,
but things improved. Several stations worked all night with 40 meters being
our best station with over 200 contacts.
We had new hams getting on HF for the first time; many other club members
worked our 5A field day status stations. We had ups and downs with antennas,
but they served us well, including Jeremys configuration-they worked as his
station was the high scorer this year. The 40-meter station was operated
entirely on solar power charging batteries. Also, this years field days
station/antenna arrangement caused very little interference among radios.
The band captains were KJ4FUU (TOM) who worked 10 meters, KA4FGY (Rich) and
N4ASX (Rick) worked 75 meters, KV3W (Jay) worked 15 meters, N4CWP (Harry)
worked 20 meters, KF7IJZ (Jeremy) handled 40 meters, and KI4D (Don) handled
6 meters. We got all kinds of bonus points, official visitors (Councilwoman
Dell Pepper w/husband), press releases, down loaded an ARRL bulletin,
message to ARRL section headquarters, kids operating radios, PR desk, and we
(Rick) are working on our total score. And, we even have a video by Jeremy
which will be up on our website.
We had 42 people for Saturdays evening meal
great barbeque. Ted (W9TCE)
kept us supplied with refreshing lemonade. Field Day is one of our biggest
activities which was demonstrated by the high turnout by the club.
ADA Tour De Cure Support
Don KI4D and Rick N4ASX supported Eric KG4DZA with the annual Tour de Cure
bike ride. The ride raises funds for the American Diabetes Association
(ADA). Don and Rick were assigned to the spot in Vienna where the Caboose
is located. No emergency traffic was passed and a good time was had. Erik
told us that each year he wonders if amateur radio is really needed but if
you listened to the 100 mile course folks, they worked their tails off.

FIELD DAY AFTER ACTION REPORT Tom / KJ4FUU and Jeremy KF7IJZ
1.) Let's get the bad news out of the way first. There was a
misunderstanding that occurred involving one of our newer members and one of
our older members regarding station operation. As a result of the dispute,
the newer member went home and resigned from the club. He may have gotten
the impression that established members of the club had more privileges than
newer members. As he is no longer on speaking terms with the club, further
outreach doesn't seem possible at this time. We only wish that he had come
to a club officer about this, because we could have gotten the problem
resolved. In the future, if you have a problem of how Field Day, or any
other club operation is being done, please contact a club officer for help,
so that this sort of thing doesn't happen again.
2.) Of lesser impact, the 10M station received interference from both 15M
and 20M voice stations, more than CW would have caused, due to the close
proximity of the antennae. The 15M station caused broadband interference
when the operator keyed up, and the 20M station caused interference around
the 1st harmonic (with two side spurs) when that operator keyed up. The 20M
interference only wiped out our ability on a few frequencies, while the 15M
station removed our ability to pull out weak signals. One possible solution
is for the club to purchase a set of bandpass filters, which a club officer
can store between operations.The cost would be $645 + Shipping for all HF FD
bands.
3.) Also, we need to be better aware of what's going on around us. It would
have been nice to have a video of those teenagers who trashed the bathroom
to show to police or a city official. We won't be blamed, I think the city
knows us better than that, but it would have been nice to have a video of
the water fight they had outside of the bathroom.
4.) Now, what was good about Field Day: lots of new hams came out and had a
chance to see and try HF operations. Ed demonstrated a cheap, simple to
construct, and effective 2M antenna, which an antenna analyzer showed to be
1.1:1 SWR across the 2M band.
5.) The 40M vertical worked a lot better than I expected, with contacts made
to the west coast and even Hawaii! And, we got to see a variety of HF
radios, including the TenTec Eagle, Icom 756ProII, and the Elecraft K3+PAN
adapter. The latter radio was brought by a guest from the Anne Arundel Radio
Club, Raven KB3MUV. The 10M station was an Elecraft K3, 15M was an Icom
IC-7000, 20M was an Icom IC-756ProII, 40M was a Yaesu FT-450D running
through a W3NQN Bandpass Filter and then connecting to either a Little
Tarheel II based vertical with 40 1/8 wave radials OR a 100 watt Par End
Fedz 20/40 antenna. 40M also was powered by a Solar Panel (a 120watt
PowerFilm Solar array) fed in to a custom "solar generator". 75M was a
TenTec Jupiter/Eagle, and 6M was a Yaesu FT-857D.
6.) I was told that we had better overnight participation than in previous
years. The 20M station contacted Hawaii after about 4:00AM Sunday. John
KK4RBB made contact with a station in the East Bay section (San Francisco),
which I had failed to make after trying for a while.
7.) Ed, W4EDF attempted FM satellite contact on Saturday, which was the one
and only opportunity to make contact with a Satellite during FD. He also
demonstrated APRS and how to make a very inexpensive and simple 2M ground
plane antenna.]
8.) The weather was decent: hot, but breezy. The rain held off until
daylight on Sunday. The Barbeque from Red Hot and Blue was a hit with
everyone.
We wish to thank all those who helped by bringing in gear, food, and advice.
We also wish to thank those who spent time educating new hams, and those who
worked on the stations. We extend special thanks to those who stayed
overnight. And of course, many thanks to those who helped set up and take
down everything.
PRESIDENTS CORNER Tom KJ4FUU
Well, we just finished another Field Day. It was fun, but I'm glad it only
comes once a year. I stayed all night for the first time, intending to catch
a nap sometime overnight, but it didn't happen. I slept a lot Sunday
afternoon.
On my first Field Day, back in 2010, I made *one* contact. Rick N4ASX saw
that I needed some mentoring in the art of operating in a contest, so he let
me operate the 7/2010 IARU HF contest from his station, showing me how to do
things. I made 40 or so contacts all over the world that afternoon, and I'm
now much better with contests. I hope everyone got a chance to operate as
much as they wanted on Field Day, but I feel I was remiss in not asking
those around me if they wanted to operate on 10M. 10M wasn't very hot, but I
was drooling over all the features offered by the Elecraft K3 that KB3MUV
brought in. If you didn't get a chance to operate and still want to, please
get in touch with club members with HF stations, such as Rick.
Rick has repeatedly offered to help new hams learn to operate on HF. If you
don't have an HF station of your own, it still doesn't hurt to practice for
next Field Day.
Many hams still only use VHF radios, and that's OK. Ham radio is diverse
enough for everyone to find a niche. The club has a lot of activities using
VHF/UHF, and there should be enough for everyone to get involved.
If some of the new hams are available around President's Day, we ask them to
please volunteer to help in the GW Birthday 10K Run and the GW Birthday
Parade on the Monday holiday.
Stay involved!
Thanks, and 73,
-- Tom KJ4FUU

DAYTON REPORT
The annual pilgrimage to ham radio mecca, otherwise known as the Dayton
Hamvention went well this year. It was a smaller than usual crowd from
Alexandria, but the overall attendance was reported to be up from last year.
There didnt appear to be any must have radios introduced this year, but for
the Alexandria members, the Alinco DJ-29T was a hot seller. In fact, they
were a hot seller in general, as KA4GFY and W9TCE got the last two from
Universal Radio and N4CWP got one of the last ones from R&L on Friday
afternoon. If youre not familiar with this Alinco, its the only ham band
radio radio for the 1.25 meter and 33 cm bands. This radio is of special
interest to us because a couple of years ago at the Hamvention, KI4MWP put a
bug in the ear of the Alinco engineers to market a dual band radio that
covers 1.25 meters and 33 cm. It was a concept last year, but was being
sold at its first Dayton after it was introduced.
In case you are wondering why those two bands, the Alexandria Radio Club is
the proud owner of great sounding repeaters on both those bands.
Speaking of new radios, one of our recent graduates, KK4RBB, went to his
first ever hamfest and bought a new ICOM ID-51 HT. That radio was
definitely a hot seller, as dealers were sold out by Friday afternoon. At
least one dealer had more shipped in early Saturday morning. Other DSTAR
radios were selling fast as well as more hams jump on the DSTAR train.
Mark your caledars now for next years Hamvention. The dates are May 16, 17
and 18.

ELMERS Corner
So far, we covered buying used radios, cheap antennas and power supplies.
Lets talk about antenna feedlines and connectors. I was getting ready for
Field Day and putting the newsletter and I read Harrys meeting minutes.
The simplest VHF antenna is the roll up J-pole with the details in the May
ARC SHORTS. It dawned on me that most of those who will want to build one
of these antennas will want to use it with their handheld VHF radios. In
the past these radios had BNC connectors so we used BNC to PL-259 (UHF)
adapters, but now handhelds use an SMA connector. SMALL and maybe a bit
difficult to put on our antennas. BUT, I wanted to give it a shot, so I
called my favorite connector, cable place and ordered a bunch of connectors
including some RG-8X SMA male connectors. WOW in one paragraph I tossed a
great deal of jargon at you and your lost in it. DONT STOP READING I
Shall endeavor to explain.
There are two types of feed lines for antennas, the balanced line or twin
lead that we use to use for our TV antennas. Twin lead is very efficient
but can be a pain to feed through a wall or work with. Good for HF but not
so good for 50 MHz and up. COAX is the cable with a center conductor, an
insulator around that center conductor and an outer conductor over the
insulator and then an outer plastic or rubber jacket. It comes in several
impedances (50, 75, 92 ohms) we are interested in the 50 ohm cable. Now
there are THREE sizes that we generally use. The big stuff is 5/8 in
diameter can be RG-8, RG-213 (Mil Spec RG-8), Low loss versions are LMR-400
or 9913. There are charts in the ARRL handbook and antenna book to show the
loss of each type of coax. This stuff is great for the home, but can be a
problem when portable or installation in a car. The next step down is
RG-8X. This is the smaller diameter stuff and 8X is almost as good as RG-8.
I use RG-8X for mobiles, and portable / Field Day / Public Service
operations. 100 of this stuff is a lot easier to deal with then 100 of
RG-8. If youre going CHEAP, then there is RG-58. This is slightly
thinner than RG-8X and not near a good, but its the stuff you can buy at
Radio Shack for 19 cents a foot or less.
Most mobile radios (CBs as well) have a standard Coax connector on the
back. In the industry its called a UHF connector. The female connector is
also known as an SO-239 and mates to the PL-259 on the coax feedline. So,
if you buy a VHF mobile you will want to make up a feedline with a PL-259
connector that goes with the coax you chose to use. If your using a new
handheld the little connector on the handheld is an SMA connector. Most of
us do not put the SMA male connector on the coax, but buy an adapter to
convert the SMA to the UHF Female (SO-239) and then connect our coax with
the PL-259s to the adapter. Some adapters convert to a BNC connector. The
BNC is what was used on UHF and up radios and handhelds before the SMA.
Its a bayonet type connector. An important point here is that adapters
cost power on transmit and some receive sensitivity.
Now we have three kinds of coax and three different kinds of common
connectors. Now I will toss in one more variable. Two kinds of connectors.
The standard for most is the solder on connector. The solder on UHF
(PL-259) for RG-8 you cut the outer conductor back exposing a length of the
center conductor and insulator and cut the insulator back so you have a
little exposed center conductor (about ½ inch) another 1/16 inch of
insulator and then about ½ inch of outer conductor exposed. You first put
the screw collar over the coax, then you put the connector body over the end
of the coax and screw the outer conductor into the connector body while
having the inner conductor feed into the center pin of the connector, solder
the inner conductor to the pin and there will be holes in the outer side of
the connector body that will show you the outer conductor. This becomes a
talent issue. You want to place solder into those holes and get a good
solder connection WITHOUT melting the insulator between the inner and outer
conductor of the coax or the insulator in the connector. I use a 250 watt
soldering gun for this.
Another approach is the CRIMP on connector. About the same initial fit up
but you also put a collar over the cable with the screw on piece. Solder or
crimp the center connector and then the insulator goes inside the connector
body and the outer conductor goes outside the connector body, then there is
a crushable collar that slides over the outer conductor. Here is the fun
part, you get your crimping tool and crush or crimp the collar down onto the
outer conductor. Faster and unless your really good with the soldering gun
works better. The cost of the Crimp kit is about $100 but the connectors
are about 50 cents cheaper and not redoing the connectors will pay off.
Now if your using RG-8X or RG-58, the solder on connector is the same but
you add a sleeve over the smaller coax. There solder on PL-259 can be more
like the crimp connector. The outer conductor is folder over the adapter
sleeve. And then the coax with the adapter is put into the PL-259. Solder
the center pin to the inner connector and then with two pairs of plyers you
tighten the adapter into the body. You can then solder through the holes in
the connector body, but you dont need to if you can tighten the adapter.
Crimp on connectors for RG-8X and RG-58 work like the standard but have a
smaller body for the smaller coax, no adapters to buy or look for.
If your working with older radios or military gear you may have to work with
the BNC connector. One of our members called these BAD NEWS CONNECTORS.
The center pin is soldered to the inner conductor and any excess solder may
cause problems
Hamfests
July 21 Maryland Hamfest and Computerfest, sponsored by the Baltimore
Radio Amateur Television Society. Its located at the Howard County
Fairgrounds, located just off I-70 and Rte 32 in West Friendship, MD. Its
an easy drive and there are usually some unique items to be had.
August 4 Berryville Hamfest, sponsored by the Shenandoah Valley Amateur
Radio Club. This is a vey nice hamfest under the trees at the Clarke County
Fairgrounds. Lots of items to be had. Its a short drive and scenic drive
from Alexandria. Not only that, the Raritans club does a barbeque lunch
that is worth the trip. Its smoked right there at the fairgrounds.
Training -
Rick asked me to do a short review of some of the methods used to study for
your amateur radio license. I may be biased, but I think a class is by far
the best way to do this, because you get the interaction with experienced
hams that can help you with those tricky questions that always seem to come
up. My philosophy is I would rather teach the student material so they have
an understanding of what they need to know, rather than teaching the
questions and the right answers to the questions. If you have ever wondered
why our classes are spread over several weeks rather than a weekend or even
a few weeks, now you know. As for the book, we use the ARRLs Ham Radio
License Manual, while other instructors use Gordon Wests book. Both are
good books for the classroom.
For the student who doesnt want to commit to one night a week for several
weeks, there is the occasional weekend class. To put it mildly, this is
like trying to take a drink from a fully charged fire hose. Its a lot of
information over two or even one day. I cant imagine anyone learns much
other than the questions and some of the right answers. Weekend courses
require advance preparation by the student and a lot of preparation by the
instructors. We tried it once and came to the conclusion the students
didnt get much out of it. In looking at the ARRLs listing of classes, I
find fewer and fewer classes being taught over one weekend. I am seeing
some taught over a few weekends.
As with everything else these days, the internet is a place many people go
to do their studying. ARRL has an on-line Technician class as part of their
suite of continuing education courses. This class uses the Ham Radio
License Manual, but the student is paired with a mentor, who is there to
guide the student through the material and answer questions. There is no
set day and time to meet, its all done via email. However, the student does
have a set time limit to complete the class. If you have ever done any of
the ARRL emergency communications courses, this is the same format, and it
does work very well.
I periodically see a prospective ham showing up on some of the radio
websites asking where/how they should get started on studying for a ham
license. As you can imagine, the answers are as different as can be. Some
people point them to the license class lookup section of the ARRLs website
and some are pointed to the multitude of on-line study websites. For the
most part, these appear to be websites where they fire a bunch of questions
at you and keep score. Some of the ones you pay real money for will keep
track of your score and keep firing questions from your problem areas until
you figure out the right answer by process of elimination. You dont learn
much, other than the questions and the right answer. You often dont know
why its the right answer. As you can tell, I am not a fan of these
websites. They are fine as a supplement, i.e., a way to get some experience
at seeing the questions and getting an idea of how you might do on the real
test.
There is at least one class that is taught as a podcast. You can download
this weeks class into your ipod or smartphone and listen in to the
instructors go through the material. I dont really know much about them, I
dont know anybody who has ever used one. Again, I dont know how the
student can ask questions to the instructor.
Not all formats work for every student. If you tried one format and it
didnt work, dont give on on becoming a ham, try another. Getting a
license has never been easier with the different study methods out there.

ARES
A few items. It is NOT TO EARLY to sign up for the Marine Corps Marathon
(MCM). This is a major event for amateur radio. Ive talked before about
public service being the payback in good will for our spectrum and for many
other benefits we get. Not the least of which is a place for the club to
meet. With all the stuff about texting and cell phones, most of these laws
carve out an exemption for amateur radio and public service radio. If you
get call tags for your car in Virginia you dont pay the vanity fee, but you
are expected to have gear installed in the vehicle.
Your assignment will be dependent on your gear for the most part. If you
have just a handheld, you will be placed on the course where you have easy
access to the primary repeaters. Some positions are in low spots and
require mobiles or mobiles with good antenna systems.
If youre on the Virginia side of the course you will need to be on site
EARLY in the day and you will be at the start of the course or at the very
last part of the course, Your time on the course will be dependent on when
the last runner passes your spot.
The second short note is to ask that you know your gear. Its a point of
professionalism that you can program your gear at these events, but I cannot
tell you how many hams have asked me to help with programming a radio with
the frequencies on race day in a parking lot at 4AM.
With the weather we have the old Boy Scout motto of BE PREPARED comes to
mind. In summer a long power outage is not too much of a problem, but a few
winters ago, some of our members were without power for days. Have a plan!
