==> FOURTEENTH ANNUAL AES SUPERFEST A SUPER SUCCESS
ARRL Sales and Marketing Manager Bob Inderbitzen, NQ1R, attended the 14th
Annual AES Superfest <http://www.aesham.com/superfest.shtml> at the
headquarters store of Amateur Electronic Supply in Milwaukee, Wisconsin
March 28-29. This event is an ARRL sanctioned hamfest that included forums,
VE testing (sponsored by MRAC), DXCC card checking and a fox hunt. ARRL
Central Division Director Dick Isely, W9GIG; Vice Director Howie
Huntington, K9KM, and ARRL Wisconsin Section Manager Don Michalski, W9IXG,
were also on hand for the event.
More than 30 vendors made the trek to Wisconsin to show off their wares.
"It was fun to visit with all of the AES staff and sales people, too. I
enjoyed discussing our new publications, especially the new format of the
'The ARRL Repeater Directory,'" Inderbitzen said.
ARRL Volunteer Counsel Jim O'Connell, W9WU, offered a forum Saturday
afternoon -- Legal Issues for Hams -- giving advice for avoiding
restrictive antenna covenants, presenting a case for installing a tower
(before legislative or zoning officials) and information on the latest
court rulings on RFI and PRB-1. ARRL Instructor Gordon West, WB6NOA,
presented a forum, encouraging the crowd to recruit, mentor and most of
all, have fun!
Inderbitzen heard from many hams while he was at the ARRL booth at
Superfest: "Most of the comments I received were very positive. There were
lots of nice words about the 'direction' of ARRL, the layout of QST and the
one-on-one experiences members have with the ARRL staff and officials. A
few folks mentioned having great visits to ARRL headquarters."
On March 27, the night before Superfest, Inderbitzen attended a meeting of
the Milwaukee Radio Amateurs' Club (MRAC) and spoke about sharing the
passion for Amateur Radio with friends and family members. This club,
founded in 1917, will celebrate 90 years of ARRL Club Affiliation in 2009.
In recognition of this milestone, Inderbitzen presented MRAC President
Howard Parks, AB9FH, with an ARRL Recognition Award "for its commitment to
Amateur Radio and to the American Radio Relay League."
==> ARRL RECOGNITION AWARDS AVAILABLE

==> GET READY FOR WORLD AMATEUR RADIO DAY ON APRIL 18
Each year on the anniversary of its founding, April 18, the International
Amateur Radio Union (IARU) marks World Amateur Radio Day. On this 83rd
anniversary of its inaugural meeting in Paris, the IARU dedicates World
Amateur Radio Day to the future of Amateur Radio with its theme, "Amateur
Radio: A Foundation for Technical Knowledge."
It is no secret that many professionals in the field of radio, TV,
communications and electronics have started their technical education as
young radio amateurs. Although Amateur Radio has a different face nowadays
-- Digital Communications, Voice over Internet Protocol, Satellite up- and
downlinks and more -- it is even of greater value as a foundation for
technical knowledge for youngsters. And much more -- it is and should be
used as a unique attraction for future young radio amateurs.
World Amateur Radio Day provides an occasion to promote and publicize
Amateur Radio. Amateur Radio clubs are encouraged to find suitable ways of
celebrating World Amateur Radio Day. Many ways can be considered --
inviting youngsters to visit radio clubs, showing up on the air with a
special call sign, organizing a station in a public area with media
coverage or publicly honoring amateurs who have made significant
contributions. Whatever method is chosen, clubs should think about
publishing a press release for the media, giving the background to World
Amateur Radio Day and promoting the value of Amateur Radio as a foundation
for a technical career.
The ARRL will be very pleased to hear how Amateur Radio clubs chose to
celebrate World Amateur Radio Day. Share your stories and photos with us,
so that they may be shared with the Amateur Radio community. E-mail your
submissions to ARRL Affiliated Club/Mentor Program Supervisor Norm Fusaro,
W3IZ <clubs at arrl.org>;. Please be sure to put "World Amateur Radio Day" in
the subject line. -- Information provided by IARU
==> ARRL COMPILES COMPLETE WORKS OF LARSON E. RAPP, WIOU
Thanks to the efforts of ARRL volunteer Bob Allison, WB1GCM, the League has
assembled the complete known works of noted QST author Larson E. Rapp, WIOU
<http://www.arrl.org/tis/info/larson/>. Rapp's remarkable contributions
spanned a period of more than three decades (1941-1962, 1972), primarily
during the month of April. Rapp was said to be from
Kippering-on-the-Charles, Massachusetts, just off Route 128.
"Like most visionaries unafraid of pushing technology beyond conventional
limitations, Larson at times was controversial among his peers and
contemporaries," ARRL Lab Engineer Mike Gruber, W1MG, said. "You can now be
the judge of just how well Rapp's theorems and trademark 'radical approach'
have withstood the test of time."
The first Rapp article, "Putting Dynamic Prognostication to Work," appeared
in the April 1941 issue of QST. In the article, Rapp expounded on his
efficient one-tube transmitter. When Rapp discussed the tuning of the
transmitter, he said, "The high coupling efficiency of the unit results in
a minimum plate current of resonance of about 0.9 ma. at 7 Mc. This is too
low a value to show on the 0-250 milliammeter that should be used for the
circuit, so you'll have to take our word for it." The transmitter was
described as having a "simple construction of the chassis which is made
from cardboard fastened by wire staples and glue. The underside is covered
with tin foil."
In "The Circular Band Theorem: Operational Advantages of Concentric
Frequency Allocations" [April 1946], Rapp theorized if the FCC assigned
"amateur frequencies in concentric circles instead of bands [the end result
would be] the consequent elimination of out-of-band operation and band edge
crowding...[making] it possible to work someone 40 or 50 kc. removed from
one's frequency." This was brought on by Rapp's claim that amateurs,
"realizing that after calling 'CQ' they had to start listening somewhere
and that somewhere was usually the edge of the band." Rapp called for bands
to be designed in "concentric circles, and the beginners should be
encouraged to start in the smallest circle. Thus, even if one managed to
get out of band -- we don't see how he could, but someone would find a way!
-- he would still be inside the next circle and amateur radio would have no
black mark against it for out-of-band operation. Further, the fact that a
beginner was encouraged to start in the inner circle would make him feel
like he was one of the boys right off, being allowed into the inner
circle!"
In the April 1960 issue of QST, a phony full-page ad announced the
formation of "Larsen E. Enterprises, Inc," supposedly off Route 128 in
Kippering-on-the-Charles, Massachusetts, with Larsen E. Rapp as president.
Bearing a "Not a Advertisement" disclaimer, the ad offered customers free
access to the company's air-conditioned "Wonder Workshop" with each kit
purchase. "If you don't have the time to assemble the entire kit yourself,
one of our engineers will be glad to do it for you, just for the pleasure
it gives him," the ad promised. "No tipping please." In the "Print Shoppe,"
customers could purchase "authentic reproductions of the rarest QSL cards
in the world." The price included having the company's "patient penman"
fill in the card with your call sign and a signal report, duplicating the
original ink and handwriting.
Rapp himself said that "In assembling this list of my articles and letters
over the years, I noticed that QST always chose to publish them in the
springtime. This practice was especially meaningful to me as spring has
historically been a time of new beginnings and in our radio hobby, a time
for new insights into old technical problems. I hope you, too, will be
helped and inspired by these writings of an old ham."
==> ANNUAL ARMED FORCES DAY CROSSBAND TEST SCHEDULED FOR MAY
The Army, Air Force, Navy, Marine Corps and Coast Guard are co-sponsoring
the annual Military/Amateur Radio communications tests in celebration of
the 58th anniversary of Armed Forces Day (AFD). Although the actual Armed
Forces Day is celebrated on May 17, the AFD Military/Amateur Crossband
Communications Test will be conducted on May 10 to prevent conflict with
the Dayton Hamvention, scheduled for May 16-18.
The annual celebration features traditional military to amateur crossband
communications SSB voice tests and copying the Secretary of Defense message
via digital modes. These tests give Amateur Radio operators and short wave
listeners an opportunity to demonstrate their individual technical skills
and to receive recognition from the Secretary of Defense and/or the
appropriate military radio station for their proven expertise. QSL cards
will be provided to those stations making contact with the military
stations. Special commemorative certificates will be awarded to anyone who
receives and copies the digital Armed Forces Day message from the Secretary
of Defense.
Look for schedules and frequencies of participating military stations to be
published in May on the Army MARS Web site
<http://www.netcom.army.mil/MARS>.

==>SOLAR UPDATE
Tad "Who bade the Sun clothe you with rainbows" Cook, K7RA, this week
reports: The past few days have had very stable geomagnetic conditions.
After unsettled to active geomagnetic indicators on March 26-28, conditions
quieted down dramatically. Combined with the nearly two-week run of
sunspots and the spring season, this makes good HF conditions. There were
actually three sunspots, beginning on March 23 with the first one and a
sunspot number of 14. March 24 and 25 each brought one new spot; the
sunspot number rose to 35 and 52 on those days. Activity peaked between
March 26-29 with daily sunspot numbers of 63, 57, 63 and 50. Yesterday,
April 3, the sunspot number was back to 14 again, as one-by-one, the three
spots drifted from view. Today's sunspot number may be back to zero, and it
may stay that way until April 18-20. Sunspot numbers for March 27 through
April 2 were 57, 63, 50, 41, 45, 25 and 24 with a mean of 43.6. The 10.7 cm
flux was 84.8, 82.9, 82.6, 80.5, 79.2, 77.8 and 75.9 with a mean of 80.5.
Estimated planetary A indices were 31, 21, 8, 8, 4, 4 and 1 with a mean of
11. Estimated mid-latitude A indices were 19, 13, 6, 6, 2, 5 and 1, with a
mean of 7.4. For more information concerning radio propagation, visit the
ARRL Technical Information Service Propagation page

* ARRL Continuing Education Course Registration: Registration remains open
through Sunday, April 20, 2008, for these on-line course sessions beginning
on Friday, May 2, 2008: Technician License Course (EC-010); Amateur Radio
Emergency Communications Level 1 (EC-001); Radio Frequency Interference
(EC-006); Antenna Design and Construction (EC-009); Analog Electronics
(EC-012), and Digital Electronics (EC-013). Each online course has been
developed in segments -- learning units with objectives, informative text,
student activities and quizzes. Courses are interactive, and some include
direct communications with a Mentor/Instructor. Students register for a
particular session that may be 8, 12 or 16 weeks (depending on the course)
and they may access the course at any time of day during the course period,
completing lessons and activities at times convenient for their personal
schedule. Mentors assist students by answering questions, reviewing
assignments and activities, as well as providing helpful feedback.
Interaction with mentors is conducted through e-mail; there is no appointed
time the student must be present -- allowing complete flexibility for the
student to work when and where it is convenient. To learn more, visit the
CCE Course Listing page <http://www.arrl.org/cce/courses.html> or contact
the Continuing Education Program Coordinator <cce at arrl.org>;.
* Notes from the DXCC Desk: ARRL DXCC Manager Bill Moore, NC1L, reports
that DXCC has completed processing applications for 2007. As such, St
Barthelemy (FJ) has been added to the DXCC computer system and Logbook of
The World <http://www.arrl.org/lotw>. With the addition, this moves the #1
Honor Roll position to 338 current entities; operators now need 329
entities to qualify for Honor Roll. ARRL "While DXCC has completed
applications for 2007, there are a number of application returns still
being mailed, so it may be another 2-3 weeks before applicants receive
their 2007 return," Moore said. "LoTW is now accepting certificate requests
for St Barthelemy; once those logs are submitted, the matches should occur
and applicants can claim DXCC credit." For programmers who use the DXCC
entity numbering system, the entity code for St Barthelemy is 516. Moore
also noted that the 2007 G4GIR/KH9 DXpedition to Wake Island has been
approved for DXCC credit: "If you had cards rejected for this operation,
please send an e-mail to the ARRL DXCC Desk <dxcc at arrl.org>; to have your
DXCC record updated."
* Hams Come to Rescue in Utah: Eldon Kearl, K7OGM, of Fish Haven, Idaho,
was driving in the Logan Canyon, Utah area last week when he came upon a
driver who lost control of her truck in the snow. Her truck fell more than
100 feet over a cliff, and two of the three passengers were thrown from the
truck. Witnesses tried to call for help on their cell phones, but the
closest cell coverage was more than a 30 minute drive away. Kearl, however,
had a radio in his car and was able to get a hold of another ham, Roger
Ellis, KE7HTE, of Logan, Utah. Kearl relayed to Ellis information about the
accident scene and Ellis called 911. First responders were on the scene
within half an hour. Although the driver and passengers in the truck
suffered only minor injuries, a spokesman for the Utah Highway Patrol said
that if Kearl and Ellis had not responded in getting help so quickly, the
injuries could have been much worse. As Kearl said, "It all worked out
pretty good." Kearl and Ellis have never met, but live relatively close to
each other; they plan on meeting each other in person soon. -- Information

* Dick Jansson, KD1K, Wins March QST Cover Plaque Award: The winner of the
QST Cover Plaque Award for March is Dick Jansson, KD1K, for his article "HF
Antennas and Restricted Living." Congratulations, Dick! The winner of the
QST Cover Plaque award -- given to the author or authors of the best
article in each issue -- is determined by a vote of ARRL members on the QST
Cover Plaque Poll Web page <http://www.arrl.org/members-only/qstvote.html>.
Cast a ballot for your favorite article in the April issue by Wednesday,
April 30.
* Exhibit Kits Available for Field Day: Visit the ARRL Field Day
information page <http://www.arrl.org/fieldday> for all the details on
Field Day rules, frequencies, forms, pins, logos and T shirts. The complete
Field Day packet <http://www.arrl.org/contests/forms/fd-2008-packet.pdf>
can be downloaded from the site as well. If you have unanswered questions
about Field Day, contact ARRL Field Day Manager Dan Henderson, N1ND, via
e-mail <fdinfo at arrl.org>; or by phone at 860-594-0236. If you want to order
exhibit kits containing printed flyers about Amateur Radio, you may order
these materials on the ARRL Web site <http://www.arrl.org/brochures/>. The
cost of the exhibit kits ranges from $8-$12 depending on shipping. To make
sure you'll have the display material in time for Field Day, your order
must be received before June 13. ARRL Field Day is always the fourth full
weekend in June; in 2008, it is June 28-29.
* Field Day Station Locator Up and Running: This year, for the first time,
the ARRL has put together a Station Locator
<http://www.arrl.org/contests/announcements/fd/locator.php> to help
amateurs or those interested in Amateur Radio find a Field Day
<http://www.arrl.org/contests/announcements/fd/> site near them. According
to ARRL Field Day Manager Dan Henderson, N1ND, many amateurs have been
asking for something like this for many years: "So far, 287 groups in 45
states and 3 Canadian provinces had registered their Field Day site with
the Station Locator." If your group would like to be a part of the Station
Locator Service, it's easy to get started. Just go to the Field Day Station
Locator Web site
<http://www.arrl.org/contests/announcements/fd/locator.php> and follow the
instructions.
* Transatlantic Balloon to Launch this Weekend: The trans-Atlantic balloon
flight of the Spirit of Knoxville V is set to launch April 5 at 2000 EDT
(0000 UTC April 6). The balloon, designed to stay aloft for more than 24
hours, will be inserted into the current jet stream at normal flight
altitudes of 30,000-40,000 feet. This will take the balloon into Europe
over the UK and France at around 40 hours into the flight if all goes well.
Using radio frequencies, the balloon transmits data detailing its current
location, distance traveled, speed, height and health of the balloon. Last
month, the Spirit of Knoxville IV made two-thirds of its journey and
crossed the tectonic plate to Europe; organizers hoped the balloon would
make to Europe, but after 40 hours and 3300 miles, the balloon lost
altitude and went into the ocean as it neared Ireland. The balloon's
payload consists of hand-made computers and radios along with a GPS and
self-authored software. The onboard computer gathers information from the
GPS like altitude, speed and temperature; the computer then determines
whether it needs to drop weight to maintain its altitude and sends this
information, via Amateur Radio frequencies, to volunteers around the globe.
Track the mission live (the live status page will only become active at
launch). See the Spirit of Knoxville Web page
<http://www.spiritofknoxville.com/> for more information.
* Tim Hulick, W9QQ (SK): ARRL has learned that Tim Hulick, PhD, W9QQ (ex
W9MIJ), Captain, USNR retired, of Schwenksville, Pennsylvania, passed away
December 28, 2007 after a lengthy battle with cancer. He was 65. Hulick, an
ARRL Life Member, also held the calls V47QQ, KG4QQ, HL9QQ and PJ9Q. A 1964
graduate of the US Naval Academy, Hulick served his country for 29 years.
Upon retiring from the Navy, he operated Watts Unlimited, producing a
lightweight HV Power Supply designed for use as a replacement in older
amplifiers. Hulick wrote several articles for QST and QEX, including
"Switching Power Supplies for High Voltage" (QEX, February 1991), "PSK31 on
the Road!" (QST, March 2000), and "A Two-Element Vertical Parasitic Array
for 75 Meters" (QST, December 1995). Hulick was on the ARRL DXCC Honor Roll
with 356 countries; he only needed BS7, but was too sick to mount a serious
effort to get them while it was most recently on the air. He worked more
than 230 counties while mobile. He also operated /MM from a number of ships
during his Naval career. Hulick was buried with full military honors at
Arlington National Cemetery. He is survived by his wife JoAnne, three sons,
a daughter and several grandchildren.
* Des Moines Hamfest Location Update: The Des Moines Radio Amateur
Association (DSMRAA) will hold their hamfest on April 27 at the 92.5 KJJY
Event Center, located at 2100 NW 100th Street in Clive, Iowa. The April
issue of QST inadvertently stated the hamfest would be held at the Iowa
State Fairgrounds.
* Belgian Satellite to Feature D-STAR Technology: Students at the
Universite de Liege in Belgium have built OUFTI-1
<http://www.leodium.ulg.ac.be/cmsms/>, a new Amateur Radio CubeSat
featuring D-STAR digital-communication protocol that is used for control
and telemetry. Amateur Radio operators from all over the world are able to
listen in on the ON0ULG D-STAR repeater on 70 cm
<http://www.jfindu.net/dstarlh.aspx?rptr=ON0ULG>; 2 meters will be
operational soon. The objective of this nanosatellite project is to provide
hands-on experience to students in the design, construction and control of
complete satellite systems, ultimately serving as the basis for a variety
of space experiments. The first satellite in the series, OUFTI-1, is a
CubeSat -- a 10×10×10 cm cube weighing in at no more than one
kilogram. -- Information provided by the OUFTI Team
