ARRL Reiterates its Case for New Band at 5 MHz
In comments filed on March 20 with the FCC on its own January Petition
for Rule Making (RM-11785), ARRL reiterated its case for a contiguous
secondary 15-kHz wide, 60-meter band of 5,351.5 to 5,366.5 kHz in
addition to the four existing discrete 60-meter channels that fall
outside the requested band, with a permitted power level of 100 W EIRP
and retention of current operating rules. More than 5 dozen comments,
all supporting the proposed allocation, were filed on the League's
petition. While some suggested more spectrum or higher power, or a
combination, ARRL said in its comments that it does not at this time
favor any changes in its initial request for a new band. The League
proposal would implement a portion of the Final Acts of World
Radiocommunication Conference 2015 (WRC-15) that provided for a
secondary international amateur allocation of 5,351.5 to 5,366.5 kHz
at a maximum of 15 W EIRP.
"Each component of this proposal is intended to maximize spectral
efficiency by permitting amateurs to operate throughout a band as
conditions and availability warrant; to give primary service
operations certainty as to where radio amateurs will be located within
the broader fixed and mobile service band between 5.250-5.450 MHz; and
it protects those primary users with the same successful interference
avoidance techniques and protocols that have been used for the past 15
years domestically, with which radio amateurs have the technical
training and experience to comply," ARRL asserted in its comments.
The League said the WRC-15 power limit of 15 W EIRP "would render the
band unsuitable for emergency communication, especially between the US
mainland and the Caribbean Basin during summer storms and hurricane
season, when atmospheric noise can be severe.
ARRL said there were good reasons for hewing to the proposal it
initially crafted and filed with the FCC, most relating to the fact
that the spectrum is shared with federal government users, and radio
amateurs must avoid interfering with them. ARRL also pointed out that
there is no "European Model" for 5 MHz, noting that the vast majority
of European countries have held to the 15 kHz agreed to at WRC-15, and
some even to the 15 W EIPR power limit. The National
Telecommunications and Information ministration (NTIA), which
regulates government spectrum, would have to sign off on any proposal,
and, ARRL noted, it has twice expressed concern about a contiguous
allocation at 5 MHz and did not favor the plan agreed to at WRC-15.
"While ARRL understands and agrees that there is a long-term,
justifiable need for an allocation at 5 MHz that is larger than the 15
kHz made available at WRC-15, and there is a very practical need for
power in excess of the 100 W PEP requested in ARRL's Petition, there
are practical considerations inherent in the ARRL Petition that stem
from an urgent and ongoing need to share the amateur allocation
compatibly with other, primary users," ARRL said. "The Amateur Service
must, of necessity, avoid interference to the primary users of this
band (which it has, to date) in order to be permitted to operate
there."
Citing its decades-long effort to obtain operating privileges in the
vicinity of 5 MHz, ARRL said there's "not really much room for debate
about the size of the band and the power limit domestically at the
present time, given the allocation status of the band (domestically
and internationally) and the necessary interference protection
requirements for primary users."
"It is hoped that as regular amateur operation in this contiguous band
develops, with the operating parameters recommended in ARRL's
Petition," the ARRL comments continued, "such operation will continue
to demonstrate compatible sharing with federal and other users and the
operating parameters and the band can be re-examined and adjusted
equitably at a later time."
ARRL said the most important thing is to have the FCC grant an
allocation before offering initiatives to alter the plan it proposed
in January. It urged the FCC to adopt the rule changes it proposed "at
the earliest possible time, if at all possible in advance of the 2017
hurricane season."
ARRL Seeking Synergy with Maker Movement
ARRL is reaching out to members of the Maker movement to explore
avenues of cooperation and collaboration, and perhaps to recruit some
new radio amateurs. Considered an extension of the arts and crafts
tradition, the Maker movement gained its own magazine, Make:, in 2005.
The philosophy of the Maker movement is reminiscent of an era when
radio amateurs built their own equipment rather than buying it off the
shelf. Those considering themselves Makers have tended to focus on
such areas as electronics and computers, robotics, 3D printing, metal
and woodworking, and even Amateur Radio, among other avocations.
The Bay Area Maker Faire attracted youngsters and adults in 2016.
Recognizing the similar characteristics of radio amateurs and Makers,
the Ham Radio exhibition each summer in Friedrichshafen, Germany, has
shared space with a Maker Faire, as Maker gatherings are known, for
the past few years. Maker Faires in the US have attracted thousands
more attendees than even the largest hamfest. The "Hamvention" of the
Maker movement takes place in San Mateo, California, and ARRL will
have a presence at events in the Bay Area in May, and in Chicago later
this year.
"Maker communities and Makerspaces are springing up across the
country, becoming the latest nexus of youthful aspirants and exotic
technology, as well as the locus of highly innovative forms of
experimentation -- including Amateur Radio," ARRL CEO Tom Gallagher,
NY2RF, wrote in his Second Century editorial, "Make It Happen," in the
April issue of QST. Gallagher considers Makers as "the next generation
of hams."
Gallagher suggests radio amateurs consider attending Maker Faires --
not only to promote and give a presence to Amateur Radio, but to learn
what they have in common with Makers, many of whom already are
licensees. (An article in the January 2017 issue of QST, "Maker Faire
Success for Ham Radio Clubs" by David Witkowski, W6DTW, is on
Gallagher's recommended reading list, as is an interview in the same
issue with Jeri Ellsworth, AI6TK, who is well known in the Maker and
gamer communities.)
Any radio amateur who enjoys tackling an Arduino or Raspberry Pi
electronics project for the shack should find some common ground in
the Maker movement. Gallagher notes in his editorial that at last
September's Maker Faire in New York City, a club in Queens offered a
simple build-a-code-practice-oscillator project, provided by
QRPme.com, that only required five components. "The attendees were
lined up six deep in two lines," Gallagher recounted. "There is
nothing to match the delight in the builder's eyes when he or she
first experiences the joy of oscillation." He hinted that this could,
in time, translate to new licensees.

Motorola Solutions Sues Hytera Communications, Alleging Patent, Trade
Secrets Theft
Motorola Solutions has filed complaints in federal court (US District
Court for the Northern District of Illinois), alleging that Hytera
Communications' digital mobile radio (DMR) products employ techniques
and systems that infringe on Motorola Solutions' patents and trade
secrets. Already known for its Land Mobile Radio Service products,
Hytera entered the Amateur Radio DMR market last year. Motorola
alleges that proprietary and patented information was taken illegally
by three former company engineers who now work for Hytera, as "part of
a deliberate scheme to steal and copy" its technology.
"Motorola Solutions believes that Hytera is intentionally infringing
its intellectual property and misappropriating its trade secrets,
which has enabled Hytera to compete unfairly by bypassing investment
in innovation," Motorola said in a March 14 news release. Motorola
Solutions General Counsel and Chief ministrative Officer Mark Hacker
characterized the copying as brazen, blatant, and willful.
The three former Motorola engineers all signed non-disclosure
agreements, agreeing to treat all Motorola trade secrets as
confidential, when they left the company to assume similar positions
with Hytera. According to the lawsuit, none of the three disclosed
beforehand that they intended to go to work for Hytera.
Motorola contends that its digital radio products were rendering
Hytera's analog systems obsolete, and rather than develop its own
digital products, Hytera stole Motorola's ideas, its attorneys allege.
Motorola said technology features it developed started showing up in
Hytera products soon after Hytera began hiring engineers who had left
Motorola in 2008, according to the lawsuit.
In a statement, Hytera, headquartered in Shenzhen, China, said it
adheres to high ethical standards and complies with "the laws and
regulations in markets where we operate," and "firmly believes that
its business practices and operations will be fully vindicated." --

Amateur Radio Gains a Champion in FAA Tower Safety Rules Controversy
The owners of certain Amateur Radio towers have a friend in FCC
Commissioner Michael O'Rielly, who feels that tower-marking provisions
required under the FAA Extension, Safety, and Security Act of 2016,
now Public Law 114-190, "could use tweaks." In a March 10 blog post,
O'Rielly expressed his belief that thousands of tower owners in the US
could face expensive, unnecessary retrofits resulting from the law's
unintended consequences. The new FAA law would impose additional
marking requirements for a small number of Amateur Radio towers,
however. O'Rielly said §2110 -- the section of the new law that
requires improved physical markings and/or lighting on towers of
between 50 and 200 feet -- is too broad.
FCC Commissioner Michael O'Rielly.
O'Rielly said that §2110 appears intended to address dangers to small,
low-flying aircraft, such as crop dusters, from temporary
meteorological testing towers (METs), among others, but that if
implemented literally, "the provision will force expensive retrofits
to potentially 50,000 existing towers," including cell and broadcast
station towers and all new towers meeting the law's broad definition,
"all with little gain to air safety," he said.
The law instructs the FAA to enact rules similar to state-level
statutes now in place that are aimed at improving aircraft safety in
the vicinity of METs set up in rural areas. In the wake of fatal crop
dusting aircraft collisions with METs, often erected on short notice,
the National Transportation Safety Board (NTSB) recommended in 2013
that states enact laws -- sometimes called "crop duster" statutes --
requiring marking and registration of METs.
"Mandating new marking and/or lighting burdens for certain temporary
aerial towers to aid agricultural pilots is a laudable goal," O'Rielly
commented. "However, the new statutory provision may have been drafted
broader than intended and, as a result, it unnecessarily captures
permanent communications towers that have little overall impact on
agricultural air safety."
A marked meteorological testing tower (MET).
While some state crop duster laws have exempted Amateur Radio towers,
the federal legislation does not. ARRL General Counsel Chris Imlay,
W3KD, has said, however, that the list of exemptions in the federal
legislation restricts the application of the new rules to a very small
subset of Amateur Radio towers. ARRL hopes to meet with FAA officials
to discuss the issue.
Although O'Rielly did not mention Amateur Radio towers as a concern,
he did allow that a small legislative fix to exempt certain towers or
to require the FAA administrator to do so "would be appropriate."
Virginia Engineering Students Tackle Satellite, Ground Station
Projects
The University of Virginia (UVA) reports that some of its engineering
students are among those at other Commonwealth schools working on
Amateur Radio satellites and matching ground stations to track them
and collect data. UVA said its student-built satellite is set to go
into space late next year aboard an International Space Station (ISS)
resupply vehicle for later deployment from the ISS. The UVA project
will be part of a joint mission with other Virginia universities to
conduct atmospheric density studies, to gain a better understanding
regarding the rates at which low-orbiting spacecraft slow down and
ultimately leave orbit when encountering the drag of the atmosphere's
outer edges.

Professor Chris Goyne; and engineering students Colin Mitchell,

"We're building our own version of NASA's Mission Control, to
communicate with our own spacecraft," said Christopher Goyne, a
mechanical and aerospace engineering professor who serves as faculty
adviser for the UVA project. "Our students have a lot of work to
accomplish prior to launch, and during the 6- to 12-month flight
mission."
The CubeSat, which will operate in the 70-centimeter amateur band,
will be the first developed and flown by UVA. Assembly and testing
will be completed this summer. UVA's CubeSat is one in a constellation
of three spacecraft being designed and built by students at UVA,
Virginia Tech, and Old Dominion University through the Virginia Space
Grant Consortium. Hampton University also is collaborating. Each
university will operate its own ground station, and students will
communicate with each other throughout the mission. They also are
collaborating on many other aspects of the project.
"One of the most worthwhile aspects of this project has been working
with the student teams at Virginia Tech, ODU, and Hampton," said
fourth-year student Colin Mitchell, KN4BBF, who is set to graduate
this spring with degrees in mechanical engineering and physics.
Mitchell is a member of the data and communications team, which is
writing software for the UVA CubeSat and will handle the radio
communication aspects. He and fellow student Tyler Gabriele, KN4BBE,
studied for and obtained Technician licenses so they can test the
radio gear, and other students associated with the project also will
earn their licenses as the project develops.
Goyne's group recently began work to construct the ground station,
with assistance from the UVA Amateur Radio Club (W4UVA). The Amateur
Radio club will provide technical expertise and assist in the
operation of the ground station.
"We've got to configure this station properly and shake out any bugs
before the mission starts," said Mike McPherson, KQ9P, a UVA ham club
trustee and ARES Assistant Emergency Coordinator for Albemarle County.
"We're going to spend about 6 months tracking other satellites as
practice."
Odd Call Signs on the Loose -- Be on the Lookout!
Special event stations sporting unusual call signs are -- or will be
-- on the air this spring and later in the year.
From Canada's Yukon Territory, keep an ear open for XO1X, now on the
air for the remainder of 2017, with plans to be active March 25-27 for
the CQ World Wide WPX (SSB) contest. The special call sign prefix is
permitted as part of Canada's sesquicentennial celebration, as is
XK150YUKON, another Yukon Canam Contest Club call sign for the
sesquicentennial, operating VY1JA remotely. Operators will include
Gerry Hull, W1VE/VE1RM, Cary Rubenfeld, VE4EA, and others.
"The XO1 prefix has not been on the air in 35 years," Hull told ARRL.
"My friend Andy, VE9DX, last put it on the air as XO1ASJ." That prefix
block was subsequently moved to Yukon Territory, he explained.
OE17ATOM will be active from Austria starting at 2200 UTC on April 21
until 2200 UTC on April 22, operating on HF, VHF, and UHF from the
only nuclear power plant that never was. The station will be set up
inside the reactor hall and control room, and there will be a live
video stream. Lower Austria radio clubs, the Icom Radio Club and
Johanniter Unfall Hilfe-Austria organized the event.
The solar array at the Zwentendorf Nuclear Power Plant.
The Zwentendorf Nuclear Power Plant was never run, owing to the
outcome of a national referendum. Today, the plant produces
electricity from some 2,300 photovoltaic panels, which can generate
450 kW peak.
From Croatia, 9A21RBM, on the air April 1-15, will commemorate the
21st anniversary of the plane crash near Dubrovnik in 1996 that
claimed the lives of US Commerce Secretary Ron Brown and 34 others.
Presumably the suffix stands for "Ron Brown Memorial." Members of
Radio Club Libertas (9A4J) will helm the operation.
Another pending special event with an atomic connection is VI5ANTLER,
operating from Maralinga Village in South Australia, is planned for
September 14-October 9. That area of northwest and south Australia is
where the British carried out atomic tests in 1957 under the code name
"Project Antler." Organizers say that this may be the first ham radio
activity from the Maralinga Section 200 Restricted Area since that
era. They are awaiting authorizations. -- Thanks to The Daily DX,

ARISS Deadline Looms to Accept Proposals to Host Contacts with Space
Station Crew
The deadline is April 15 for schools and formal or informal
educational institutions and organizations -- individually or working
in concert -- to submit proposals to host Amateur Radio contacts next
year with ISS crew members. Amateur Radio on the International Space
Station (ARISS) anticipates that contacts will take place between
January 1 and June 30, 2018. Crew scheduling and ISS orbits will
determine the exact contact dates. Proposal information and documents
are on the ARRL website.
To maximize these radio contact opportunities, ARISS seeks proposals
from schools and organizations that can draw large numbers of
participants and integrate the contact into a well-developed education
plan. Each FM-voice contact lasts about 10 minutes -- the length of a
typical overhead ISS pass from horizon to horizon.
Because of the nature of human spaceflight and the complexity of
scheduling activities aboard the ISS, organizations must demonstrate
flexibility to accommodate changes in contact dates and times.
In the US, ARISS is a collaborative effort between ARRL and AMSAT, in
partnership with NASA and the Center for the vancement of Science in
Space (CASIS).
Contact ARISS for more information.

ARRL "60-Second Century" Videos Preview QST Editorials: ARRL CEO Tom
Gallagher, NY2RF, is now supplementing each of his QST "Second
Century" editorials with a "60-Second Century" video. These videos
offer a glimpse of the content in each month's QST editorial. ARRL
began producing "60-Second Century" with the March QST editorial, and
each video is posted on the ARRL YouTube channel, as well as made
available through ARRL social media platforms (Facebook, Twitter, and
Instagram). Videos will become available on the 10th of each month,
when the digital edition of QST is released to members, and they will
be archived. For his inaugural "60-Second Century," Gallagher hit the
New England National Scenic Trail in Connecticut to review the success
of the National Parks on the Air (NPOTA) program in 2016, the topic of
his March QST editorial.
AM Rally on April 1-3 Weekend an Opportunity to Try a Vintage Mode: If
you're not familiar with full-carrier amplitude modulation (AM) or
have never used it on the air, you'll have a chance during the AM
Rally during the April 1-2 weekend, on the bands between 160 and 10
meters (except 30, 17, and 12 meters) plus 6 meters. Once the primary
voice mode on the ham bands, AM eventually gave way to SSB, a form of
AM. Yet AM has remained popular among dedicated radio amateurs who
consider it their primary operating mode. Many modern transceivers
include an AM button. "Whether your rig is software defined, solid
state, vacuum tube, hybrid, homebrew or broadcast surplus, you'll be a
welcome part of the AM Rally," said Clark Burgard, N1BCG, who is
spearheading the event with Steve Cloutier, WA1QIX, and Brian Kress,
KB3WFV. The AM Rally starts on Saturday, April 1 at 0000 UTC (Friday,
March 31, in US time zones) and concludes at 0000 UTC on Monday, April
3. Certificates will be awarded to high-scoring stations in each of
five power classes, both for most contacts and most states/provinces
worked. The AM Rally website has full details.
Ulrich Rohde, N1UL, to Receive Distinguished Achievement Award from
IEEE Antennas and Propagation Society: Ulrich Rohde, N1UL, will
receive the Distinguished Achievement Award from the IEEE Antennas and
Propagation Society this summer. A formal presentation will be made at
the IEEE Antennas and Propagation Society Symposium, July 9-14, in San
Diego, California. The Distinguished Achievement Award cites Rohde's
outstanding career achievement: "For pioneering work and contributions
to the field of Antennas and Propagation, leading to development of
wireless communication systems for industrial, military and space
applications." In 2016, the IEEE Microwave Theory and Techniques
Society honored Rohde with that year's Microwave Application Award,
citing his "significant contributions to the development of low-noise
oscillators." Rohde is the author of some 200 scientific papers and
books, and has written articles for QST and QEX.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: The Sun just completed an extended
period (16 days) of zero sunspots. None were visible on March 4, one
showed up on March 5, and then there were none from March 6 through
March 20. Finally, one sunspot group appeared on March 21-22, yielding
a sunspot number of 12 for both days. Some explanation: Every group of
sunspots counts as 10 points, and every sunspot within those groups
counts for 1 point, so the minimum non-zero sunspot number is 11.
The average daily sunspot number over the March 16-22 reporting week
was 3.4, compared to zero during the previous 7 days. Average daily
solar flux bumped up from 70.3 to 71.2.
The average daily planetary A index increased from 8.1 to 10, and the
average mid-latitude A index rose from 6.4 to 7.1.
The mid-latitude A index is measured at one magnetometer at Wallops
Island, Virginia, while the planetary A index is calculated based on a
number of magnetic observatories, most in the Northern Hemisphere.
Predicted solar flux is 74 on March 23; 75 on March 24-25; 76 on March
26-29; 72 on March 30-April 4; 71 on April 5; 70 on April 6-17; 71 on
April 18, and 72 for April 19-May 1.
Predicted planetary A index is 20 and 14 on March 23-24; 8 on March
25-26; 20, 38, 24, 20, and 18 on March 27-31; 15, 20, and 15 on April
1-3; 12 on April 4-5; 10 on April 6; 5 on April 7-16; 8, 12, 20, 8, 5,
and 8 on April 17-22, and 8, 35, 30, 20, 18, 15, 20, and 15 on April
23-30.

Sunspot numbers for March 16 through 22, 2017 were 0, 0, 0, 0, 0, 12,
and 12, with a mean of 3.4. The 10.7-centimeter flux was 70.5, 70.5,
70.2, 71.2, 72.7, 71, and 72.5, with a mean of 71.2. Estimated
planetary A indices were 6, 4, 2, 2, 3, 26, and 27, with a mean of 10.
Estimated mid-latitude A indices were 5, 3, 1, 2, 2, 18, and 19, with
a mean of 7.1.
