ARE DUX" (then again maybe not) By George W. Dowell—K0FF (Courtesy e-ham.net)
"Air Dux" inductors were once plentiful and inexpensive. Not so today. Even if they were, HAMs like to
make their own apparatus when possible. Here is one method that I have long used to make evenly
spaced, nice looking coils of all sizes.
Make your own loading coils for antenna projects using Caterpillar Grommet strips. Also called flexible
grommets, flexible bushings etc. These are used by installers to form protective bushings around the
edges of holes cut into sheet metal, and come in strips that are cut to desired length then snapped into the
hole to cover the raw edge. We used to use them when installing 2-way radios to line the holes we made
in the firewall to pass the heavy 12V wires. The evenly spaced notches make an ideal form and support
for AIR DUX knockoffs. Use Duco or Testors model cement to secure the wires in the strips before re-
moving from the temporary forms. Nylon Grommet strips can be purchased at McMasters, as well as
many other supply houses.

notch and wrap the coil tightly. Spread plastic cement down the strips when the coil is

Boy Scout Jamboree Hosts Space Station Ham Radio Contact
Low Band Operations Will be Focus for Mozambique DXpedition
07/24/2013 European Space Agency Astronaut Luca Parmitano, KF5KDP, aboard the International Space Station spoke July 20 via ham radio with Scouts attending the 2013 Boy Scouts of America National Jamboree, July 15-24, at the Summit Bechtel Reserve in Mount Hope, West Virginia. The Amateur Radio on the Interna-tional Space Station (ARISS) program arranged the 2 meter contact between the Scouts’ K2BSA and NA1SS.
“What really matters is to be good at what you do,” Parmitano told
the Scouts, “so, pick something you like, love it and be really good
at it.” Parmitano also said that the stars look different — more
natural — from the ISS but appear the same size as on Earth.
Ditto for planets. ARISS Technical Mentor Bob Greenberg,
W2CYK, coordinated the contact with the Jamboree. Some 40,000
attendees were anticipated at the National Jamboree over its 10 day
run. Amateur radio has been a part of the Jamboree experience
since 1953, when K6BSA was on the air from Irvine Ranch in Cali-
fornia. An ARISS direct contact with Space Station Commander
Doug Wheelock, KF5BOC, was a highlight of K2BSA’s activities
during the BSA’s centennial National Jamboree at Fort A.P. Hill,
Virginia, in 2010.
On July 22, students at Colegio Uruguá, in El Pinar, Uru-
guay, spoke with the ISS crew via LU8YY. An ARISS contact also
was scheduled this with students at the Scuola Italiana di Montevi-
deo in Uruguay. Visitors to the European Space Agency’s Space
Camp 2013 in Radstadt, Austria, spoke July 24 with the ISS crew
via a telebridge between IRØISS and VK4KHZ in South Australia.
The theme of this year’s camp is “Space Exploration.” Early next
month the ISS crew will speak with Scouts attending the 2013
Space Jam 7 at Octave Chanute Aerospace Museum in Rantoul,
Illinois. Some 2000 Boy Scouts, Girl Scouts and their leaders from
20 states are expected to be on hand for Space Jam 7. Also in early
August the ISS crew will speak via ham radio with students attend-
ing the 2013 AirVenture Oshkosh air show in Wisconsin. Some
500,000 visitors attend the air show each year.
The organization has a student membership of more than
20,000. On the day of the contact 125 young women and their
mentors involved in the aerospace industry in some way with the
EAA’s Women Soar program are expected, in addition to groups
from aviation high schools from Florida and California. The ISS
crew has been using a 5 W Ericsson hand-held transceiver for con-
tacts in recent months, because of problems with the higher-power
Kenwood radio on board. This can make terrestrial copy difficult,
and ARISS volunteers have had to beef up ground-station receiv-
ing capabilities to ensure a successful contact. ARISS has recorded
more than 800 ISS school contacts since the program began in late
2000. ARISS is an international educational outreach with partici-
pation from ARRL, NASA, ESA, the Russian Space Agency
(ROSCOSMOS), CNES, JAXA, CSA and AMSAT. — ARISS
07/24/2013 With less than 3 months to go until it’s on the air in October, the C82DX Mozambique DXpedition team is continuing its preparations. Heading up the DXpedition are Don Greenbaum, N1DG, and Tom Harrell, N4XP. “We now have secured the vehicles and trailers that will take us overland from Pretoria to Xai Xai (KG64), Mozambique,” the team reports. “Low Band operations remain the primary objective, and we have secured both Titanex and Battle Creek
Special verticals.” The C82DX team says its South African members, ZS6P and ZS6RI, have traveled to Xai Xai, Mo-zambique, to map the operating site — directly on the ocean in the southern part of Mozambique — and to make rental arrangements. In addition to the team license, team members have all received personalized C92 call signs. During the day, C82DX will operate all HF bands plus 6 meters. The DXpe-dition has posted an operating plan on its website. The group
07/21/2013 The dates for the next H4ØFN DXpedition to Temotu by Siegfried Hari, DK9FN, are set. The single-op DXpedition will take place from December 21, 2013, until January 10, 2014. Hari has his airline ticket, and the license, good until 2014, is in hand. Hari says he plans to stay a week longer than usual, since he’s unsure about making it back for another in 2014 (he operated as H4ØFN in 2010, 2011 and 2012), and there is some work to do on the island to support poor people and the hospital in Temotu. This visit will be to a different island that has a new airfield, Lom Lom (OC-065),
60 miles away from his previous location. The last three visits were to the main island, Nendo (OC-100). CW is his favorite mode, but he admonishes, “Keep your CW at a moderate speed.” He will try to do more SSB on this next visit. QSL H4ØFN via DK9FN, direct or bureau. DK9FN asks stations working H4ØFN to give him a “real and true” signal report, and he has posted additional advisories and caveats for those hoping to put H4ØFN in the log. — Thanks to The Daily DX

07/26/2013—According to news reports, hams in Ha-waii and California played a role July 23 in efforts to rescue the two-person crew of a sailboat stranded on a reef more than 3500 miles away in Micronesia. The US Coast Guard continues to monitor the situation. The vessel C’est la Vie, a 53-foot sailboat reported running aground on a reef in western Chuuk Lagoon. When the situation developed, Big Island Amateur Radio Club member Richard Darling, AH7G, was in contact with John Bush, KH6DLK/V63JB, and friends in the Fed-erated States of Micronesia. Bush won the 2012 ARRL International Humanitarian Award for promoting the development and welfare of the population of the Is-land of Federai in the Ulithi Atoll, FSM, in part through establishing communication infrastructure and promot-ing ham radio. On July 23 he was in Northern Califor-
nia testing a new antenna to help him keep in better touch with his contacts within the FSM. During the contact, Darling and his wife Barbara, NH7FY, heard the distress call, in which the crew reported the vessel was taking on water. The Darlings were able to hear the signal well and pass along important information about the sailboat’s location and the severity of the crew’s situation, which the Darlings relayed to the Coast Guard. The crew had told the Coast Guard they thought they could walk ashore on the reef and had a life raft and safety gear. On July 24, the Coast Guard said the vessel’s radio had gone silent, and Bush and the Darlings “were mostly playing a waiting game,” the Ha-waii Tribune-Herald reported July 25. The paper ran an article about Bush’s ARRL award in May.
