> + FORECASTERS CALLING FOR "NEAR-NORMAL" HURRICANE SEASON
Forecasters with the National Hurricane Center are calling for a
"near-normal" Atlantic hurricane season for 2012. In its initial
outlook for the 2012 Atlantic hurricane season -- which began Friday,
June 1 and runs through November 30 -- the National Weather Service's
Climate Prediction Center (CPC) is calling for a 50 percent probability
of a near-normal season, a 25 percent probability of an above-normal
season and a 25 percent probability of a below-normal season. The 2012
hurricane season began early when Tropical Storm Alberto and Tropical
Storm Beryl both developed several days before the official start of
the season, the first time since 1908 that two tropical storms
developed early; the only other year with two storms so early in the
season was 1887.
CPC forecasters say that there is a 70 percent chance of having 9-15
named storms, of which four to eight could become hurricanes, including
one to three major hurricanes (Category 3, 4 or 5). These ranges do not
represent the total possible ranges of activity seen in past similar
years. Tropical systems acquire a name upon reaching tropical storm
strength with sustained winds of at least 39 miles per hour. Tropical
storms become hurricanes when winds reach 74 miles per hour and become
major hurricanes when winds increase to 111 miles per hour. An average
season has 12 named storms, including six hurricanes with three
becoming major hurricanes. Read more here

> + CHECK YOUR MAILBOX FOR THE JULY 2012 ISSUE OF QST
This July issue of QST features an in-depth look at Solar Cycle 24.
With its slow start, many feared Solar Cycle 24 might not be as active
as previous cycles. But if you've been on the air in the last few
months, you know that the higher bands are exploding with activity.
Propagation guru Carl Luetzelschwab, K9LA, takes a look at the current
solar cycle and lets readers know what they can likely expect in the
coming years. So why not set aside a couple of hours, grab a snack and
get ready to explore the July issue of QST.
When you think of dipole antennas, you probably envision a horizontal
wire with a vertical wire hanging down from its middle. Jeff Brone,
WB2JNA, couldn't put up a traditional dipole in his third-floor
apartment, so played around with its configuration and came up with a
new model. In his article "A Dipole Doesn't Have to Be Straight," he
explains that even though some antenna is better than no antenna, just
about any kind of antenna will work.
If you've ever wanted to try the new software-defined radios, but
weren't too keen to give up your analog equipment, take note. Alex
Schwarz, VE7DXW, has found a way to upgrade an older analog radio to an
SDR at a low cost. In his article "SDR Upgrade for Analog HF Radios,"
learn how he created a software and hardware interface for different
models of radios, produced a software package that can be used by
developers to run on Windows-based platforms and used this software for
the demodulation of USB, LSB and CW.
The ARRL EXPO at the 2012 Dayton Hamvention was a resounding success.
With tons of exhibits within the EXPO -- including the DIY Stage, the
Youth Lounge and DX activities -- the thousands of Hamvention goers
were never bored. ARRL News Editor S. Khrystyne Keane, K1SFA, explores
the fun that is Dayton in her article "ARRL EXPO at the 2012 Dayton
Hamvention." In the upcoming digital edition of the July issue, QST
Technical Editor Joel Hallas, W1ZR, takes an in-depth look at the
dozens of new products that vendors introduced this year at Hamvention.
Look for the digital edition to be online in mid-June.
More than 30 years ago, the IARU offered a no-frills 20 meter CW
transceiver, dipole antenna, headphones and a Morse code key to budding
hams in Asia and Africa. In 2012, one of these transceivers, sent from
ARRL Headquarters, found its way back to Newington. While its journey
back to the US remains a mystery, QST Editor Steve Ford, WB8IMY, tells
the transceiver's story in his article "A Transceiver Comes Home."
ARRL Test Engineer Bob Allison, WB1GCM, takes a look at the Alinco
DJ-G29T dual-band handheld transceiver in this month's Product Review.
He says the rig "covers the 1.25 and 33 cm bands - a unique
combination. With this radio, amateurs can access the 33 cm band
without having to convert commercial service transceivers." QST
Technical Editor Joel Hallas, W1ZR, checked out the WaveNode WN-2d
station monitoring system, saying that it "provides useful accuracy and
a lot of flexibility in terms of what you can measure and how you can
display it. I found it a useful tool and a good adjunct to my station."
Of course, there are the usual columns you know and expect in the July
QST: Happenings, Hints & Kinks, The Doctor Is In, Short Takes,
Technical Correspondence, How's DX and more. Look for your July issue
in your mailbox. QST is the official journal of the ARRL, the national
association for Amateur Radio. QST is just one of the many benefits of
ARRL membership. To join or renew your ARRL membership, please see the

> + SILENT KEY: FORMER "THE WORLD ABOVE 50 MHZ" CONDUCTOR GENE
ZIMMERMAN, W3ZZ (SK)
Gene Zimmerman, W3ZZ, of Gaithersburg, Maryland, passed away on
Sunday, June 3. He was 71. Zimmerman wrote the popular QST column "The
World Above 50 MHz" from 2002-2011. He also served on the ARRL Contest
Advisory Committee, edited the VHF contesting column for CQ Contest
magazine during its five-year lifespan and was director of the CQ VHF
Contest from 2000-2002. An ARRL Life Member, Zimmerman earned VUCC on
six bands: 50, 144, 222, 432, 903 and 1296 MHz, as well as DXCC, Worked
All States and Worked All Continents on 6 meters. He was an early
proponent of -- and participant in -- aggressive contest log checking.

> ARRL IN ACTION: WHAT HAVE WE BEEN UP TO LATELY?
This feature is a concise monthly update of some of the things that
the ARRL is doing on behalf of its members. This installment -- which
covers the month of May -- takes a look at the new digital edition of
QST, the ARRL EXPO at the 2012 Dayton Hamvention, the League's response
to the FCC's request concerning impediments to Amateur Radio, draft
band plans for 13 and 33 cm, the results of the ARRL Video Contest,
reports from the Official Observer Desk and more. Read more here
.
> + ARRL BOARD OF DIRECTORS APPROVES 9 CM BAND PLAN
The ARRL
Board of Directors has unanimously voted to approve the 9 cm band plan,
as presented by the ARRL UHF/Microwave Band Plan Committee. Earlier
this year, the committee asked
radio amateurs for comments on a proposed 9 cm band plan, explaining
that the purpose of these band plans is to share information about how
the amateur bands are being used and to suggest compatible frequency
ranges for various types of applications. The committee also recognized
that local conditions or needs may necessitate deviations from a band
plan, and that regional frequency coordinating bodies may recommend
alternatives for use in their respective regions. Read more here

> SOLAR UPDATE
Tad "There's a fire starting in my heart
" Cook, K7RA, reports: The
average daily sunspot numbers increased about 60 percent during the
past week (May 31-June 6), when compared to the previous seven days
(May 24-30). The increase was 48.5 points, from 81.9 to 130.4. The
average daily solar flux was also up -- 18.6 points from 111.6 to
130.2. This increase in solar activity began June 1. On May 29, the
daily sunspot number was 73, with four sunspot groups visible: 1486,
1488, 1490 and 1492. On May 30, the size of groups 1486, 1488 and 1492
diminished, but 1490 grew, and the sunspot number was 78. On May 31,
sunspot groups 1486 and 1488 disappeared, and new groups 1493, 1494 and
1495 appeared, but the daily sunspot number was still about the same,
76. On June 1, three new groups appeared -- 1496, 1497 and 1498 -- and
the daily sunspot number jumped to 151. The next day the sunspot number
was 113. On June 3, sunspot group 1499 appeared and the sunspot number
was 133. On June 4, three more sunspot groups arose: 1500, 1501 and
1502. Groups 1490 and 1492disappeared, and the sunspot number jumped
again, this time to 155, the high for the week and the highest since
May 14 when it was 156. Geomagnetic activity peaked on June 3, when the
planetary A index was 19, and the high-latitude college A index was 33.
The activity continues, with the planetary A index on June 4-6 at 16,
17 and 17, and the predicted planetary A index for June 7-8 at 12 and
8, followed by 5 on June 9-17. Geomagnetic activity is expected to
increase again, with a predicted planetary A index on June 18-20 at 15,
12 and 8. For June 21-25 a planetary A index of 5 is expected, followed
by another peak at 15 on July 1 and again on July 15. The predicted
solar flux is 140 on June 7-9, 135 on June 10-11, 130 and 125 on June
12-13, 120 on June 14-15, 115 on June 16-18, and 110 on June 19-26. The
recent geomagnetic activity was caused by a coronal hole, an opening in
our Sun's magnetic field, allowing solar wind to spew forth. Look for
more on the ARRL website on Friday, June 8. For more information
concerning radio propagation, visit the ARRL Technical Information
Service Propagation page
