Charlotte NC Digital Radio Group is kinda nuts for the DV systems. They
don't pick favorites – they put them all up. Their D-STAR system is
older and more evolved (multiple sites on 144, 440 and 1200), but
they've added DMR/MotoTRBO in a big way, and recently installed one of
the Yaesu C4FM "Fusion" repeaters (though they're not "fusing" it - they
run it digital only). They've got an NXDN repeater on the bench. Only
P-25 is missing.
In this talk from the Charlotte Hamfest, Roland
Kraatz W9HPX presents the research he's done on D-STAR, DMR and Fusion.
No on-the-air comparisons (see Episode 161 for that). This is a slide
show that compares operational capability and some tech specs.
a few weeks away from Yaesu's North America release of WIRES-X, the
Internet linking system for Fusion, so Roland only has a few details on
that based on manuals.
Here are links to some of the resources Roland talks about:
On April 18th 1925, members of 25 countries meet in Paris
France and formed the International Amateur Radio
Union also known as the IARU.The
creation of the IARU led to the International Radiotelegraph Conference 2 years
later.At this conference Amateur Radio
was granted the frequency allocations still used today on 160, 80, 40, 20, and
10 meters.To celebrate this landmark
event amateur radio operators recognize April 18th as World Amateur Radio
Day.Groups will promote their
activities on social media by using the hash tag #WARD2015
on Twitter and Facebook. IARU will list
all WARD activities on this page. More

For many years young
electronic technicians have been taught the "hole” theory of
electronics. This theory explains how electrons move along conductors
and semiconductors. The theory has been good enough to
satisfy or keep at bay anyone who might otherwise question the theory.
However, after a
number of years working in the electronics industry we have come to
realize that the hole theory may not be correct. My theory which has
been proven time and again by personal observation is
that electronics works on smoke. Yes – that’s right. I recently learned
that every manufacturer encapsulates a certain amount of smoke in every
electronic component they build. The smoke is what does the work. You
have probably noticed that a component will
quit working when you let the smoke leak out.
my theory. I have documented this many times and it this theory sure
beats the "hole” theory. I’ve never seen holes in a wire and why don’t
the electrons pour out of the end of the wire
if it is broken?
Last week, in an effort to continue our regular One-Day Technician License Class, we reduced the class to a half day review. The class went well giving our instructors food for thought on making future classes a half day test review.
Several Mid-State ARC members participated in a half day Building Stronger Clubs workshop on March 7th. Attending were Ken KD9AMA, Rhonda WS9H, Steve N9DC, Bruce K9ICP, Sam WA9VBG, Joe KZ9H and Jack W8ISH. The Indiana Radio Club Council workshop focused on problems and solutions for boosting attendance at club meetings and public service events. Nearly two dozen hams from around the state offered ideas to solving club related problems.

ARRL January VHF Contest Offers a Break from Winter’s Doldrums
Getting cabin fever?Well here’s a
chance to get ‘shack’ fever to brighten your mood.Its time for the January VHF contest!Don’t be fooled into thinking this means 2
meters only, its ALL frequencies above 50 MHz.Think of it as a frozen field day staring at
1900 UTC on Saturday, January 24, and it wraps up at 0359 UTC on Monday,
January 26.Just like field day your
challenge is to work as many stations possible in as many grids possible. For 2015 three new categories have been introduced. The league does ask
that you keep the calling frequencies open in their respective bands such as
the 146.52 MHz on 2 meters. More details and log submission info at the ARRL link below:
After several months of
planning, The ARRL
Library is now live! The online Library is a free repository of
educational presentations and oral histories. It is aimed at helping to
preserve Amateur Radio’s history and to educate clubs and individuals.
CQ combining January/February issues, closing CQ Plus Digital supplement
CQ magazine today announced that
it will be publishing a combined January/February 2015 issue and will be
ceasing publication of its 'CQ Plus' digital edition supplement as of the March 2015 issue.
Both moves are intended to help restore the
magazine's normal schedule for its print edition and to strengthen its
foundations moving forward as it enters its eighth decade of
publication, said Publisher Dick Ross, K2MGA.
"These decisions were not made lightly," he added,
"but in recognition of the realities of the publishing industry. It's a
tough time to be in the magazine business, and we appreciate the
patience and loyalty of both our readers and our advertisers."
CQ will continue to publish both print and digital
editions, but the digital edition will no longer contain the 50-60
additional pages each month that constituted " CQ Plus." Editor Rich Moseson, W2VU,
noted that he hopes to include some former CQ Plus content within the
pages of CQ, but says ham radio will remain the magazine's primary
focus, as it has been for the past seven decades. CQ is marking its 70th
anniversary of publication as of its January/February issue.
As a consequence of the changes, CQ Plus Editor Richard Fisher, KI6SN,
will be leaving the CQ staff after serving for many years as a
columnist for, and then as editor of, Popular Communications, WorldRadio
Online and CQ Plus. He was also CQ magazine's Emergency Communications
Editor. "We will miss Richard's many contributions to CQ's products,"
noted Moseson, "and thank him for his many years of service to our
Subscribers to both the print and digital editions
of CQ will have their subscriptions extended by one month due to the
combined January/February issue.
Last year was a busy year no matter if you
count the events in our personal or ham radio lives.In the world of ham radio we saw a LOT of
happenings.Not only was it the year we
celebrated the 100th anniversary of the American Radio Relay League,
Log Book of The World took off in popularity, SSTV was coming from space and interest in amateur radio continues
to grow as we venture into a new millennium.

about the year in review by Jeff KE9V.
Bob Heil Receives Honorary Doctorate From University of Missouri
The University of Missouri-St. Louis granted an honorary Doctor of Music and Technology to Bob Heil during its December 20th commencement ceremony. Heil is recognized by the university for his contributions to the world of broadcast, live and studio sound, and innovations to the Amateur Radio industry. In addition to receiving the honor, Bob spoke at the commencement.
"Bob Heil's lifelong accomplishment and ongoing innovation speaks for itself," said Marcel Bechtold, the manager of information technology at UMSL who nominated Heil for the honorary doctoral degree. "He continues to add to his many years of research in sound reinforcement and shares his wealth of knowledge in workshops, conference presentations, authored books, podcasts and at educational institutions worldwide. His passion for playing the theater organ and his interests in electronic technology gained in amateur radio at an early age were great foundations, allowing his creative juices to flow through the decades."
"I am humbled and thrilled to receive this honor," said Heil. "Throughout my life I have held the belief that human stories, whether told through conversation or song, help tell who we are as people. I’ve been blessed to be part of how those stories get conveyed to the world." The University of Missouri System is a state university system providing centralized administration for four universities, a health care system, an extension program, five research and technology parks, and a publishing press. More than 75,000 students are currently enrolled at its four campuses. The health care system operates several hospitals and clinics in central Missouri, while the extension program provides distance learning and other educational initiatives statewide. PCARS
