ARRL to FCC: Amateurs and Vehicular Radars Can Play Nicely Together on
77-81 GHz
In comments filed on April 6 in response to a February FCC Notice of
Proposed Rulemaking and Reconsideration Order (NPRM&RO) in ET Docket
15-26, the ARRL has told the Commission that it should make no change
in the Amateur Radio allocation at 76-81 GHz and impose no additional
regulatory constraints on Amateur or Amateur-Satellite uses of the
band. The League said the FCC should proceed with authorizing
short-range radar (SRR) systems for automotive applications in the
band under Part 15 rules, and that such applications are compatible
with amateur operations in the band.
In its NPRM&RO, the FCC solicited comment on issues involving expanded
use of various radar applications in the 76-81 GHz band, which Amateur
Radio shares with other services. The band 77.5-78 GHz is allocated to
the Amateur and Amateur Satellite services on a primary basis, and to
the Radio Astronomy and Space Research services on a secondary basis.
The NPRM&RO was in response to a 2012 Petition for Rulemaking
(RM-11666) by Robert Bosch LLC and to two petitions for
reconsideration of a 2012 Report and Order (R&O) addressing vehicular
radar systems in the 76-77 GHz band. ET 15-26 incorporated earlier
proceedings.
In its comments, the ARRL suggested that the FCC overreached in
proposing unjustifiable changes at 77-81 GHz on its own initiative.
"There is not, anywhere in the four corners of the Bosch Petition for
Rule Making or in any comments that have been filed thus far in
response to RM-11666, any suggestion that there is any incompatibility
between Amateur Radio operation and automotive radars," the ARRL said.
"Quite the contrary." The League said a credible, current ITU study
has "definitively established" compatibility between short-range
automotive radars and Amateur Radio.
The ARRL said Bosch's filing of its Petition followed "extensive
discussions and technical evaluations between ARRL and Bosch" that
making spectrum at 77-81 GHz available for automotive radars "would
have no significant impact on the Amateur Radio Service." Bosch, the
League pointed out, "did not propose a domestic spectrum allocation
for vehicular radar devices and systems," just modification of the FCC
Part 15 rules to permit vehicular radars at 78-81 GHz on the same
basis that these radars now operate in the US at 76-77 GHz -- on a
non-allocated, non-interference basis.
The ARRL said that no changes are necessary in the Amateur Radio
domestic primary allocation at 77.5-78 GHz or in the secondary amateur
allocation at 77-77.5 GHz or 78-81 GHz to accommodate automotive radar
systems at 77-81 GHz. "Nor are any additional Part 97 rules necessary
to accommodate compatible sharing of that band between radio amateurs
and automotive radar systems," the League added. "Indeed, that is the
position of the United States in anticipation of consideration of
WRC-15 agenda item 1.18 later this year."
The League characterized as "both premature and poor spectrum
management" the FCC's proposal to unilaterally permit unspecified
fixed radar systems throughout the 76-81 GHz band "without the benefit
of any completed, definitive studies relative to the compatibility of
fixed radar systems with automotive radar, radioastronomy and/or
Amateur Radio in this band."
Any consideration of fixed radars at 77-81 GHz, the League said,
"should await the completion of conclusive, refereed compatibility
studies that credibly establish compatibility with incumbent
services." Read more.
World Amateur Radio Day is April 18!
On Saturday, April 18, radio amateurs worldwide will take to the
airwaves to celebrate World Amateur Radio Day (WARD). It was on April
18, 1925, that the International Amateur Radio Union (IARU) was
founded in Paris, with ARRL Co-Founder Hiram Percy Maxim, 1AW, as its
first president. The primary purpose of World Amateur Radio Day is to
highlight Amateur Radio and its benefits to countries and communities.
The IARU said World Amateur Radio Day is an opportunity for IARU
member-societies to demonstrate Amateur Radio to the public and make
friends with other amateurs around the world. Special event stations
will be on the air over the April 18-19 weekend to highlight World
Amateur Radio Day and the IARU's 90th anniversary.
"Since its founding, the IARU has worked tirelessly to defend and
expand the frequency allocations for Amateur Radio," the IARU said in
marking World Amateur Radio Day. "Thanks to the support of enlightened
administrations in every part of the globe, radio amateurs are now
able to experiment and communicate in frequency bands strategically
located throughout the radio spectrum."
The 1925 IARU Congress in Paris. ARRL Co-Founder Hiram Percy Maxim is
third from the right at the front table.
The International Telecommunication Union (ITU) has recognized the
IARU as representing the interests of Amateur Radio. Today, Amateur
Radio is more popular than ever, with more than 3 million enthusiasts
around the world, the IARU has estimated. As 2015 will also mark the
150th anniversary of the ITU, the IARU has adopted the theme, "ITU &
IARU: Celebrating 150 years of Advancing the Telecommunication Art"
for World Amateur Radio Day 2015.
From 25 countries in 1925, the IARU has grown to include more than 160
member-societies in three regions. IARU Region 1 includes Europe,
Africa, the Middle East, and Northern Asia. Region 2 covers the
Americas, and Region 3 is comprised of Australia, New Zealand, the
Pacific island nations, and most of Asia.
"April 18 is the day for all of Amateur Radio to celebrate and tell
the world about the science we can help teach, the community service
we can provide, and the fun we have," the IARU said. Read more.
ARRL Teachers Institutes Want to Equip Teachers to Meet the STEM
Challenge
The 2015 ARRL Education & Technology Program (ETP) will offer three
introductory sessions and one advanced Teachers Institute on Wireless
Technology seminar for educators this summer. The 4-day introductory
(TI-1) sessions will be held June 22-25 at Parallax in Rocklin,
California; July 7-10 at ARRL Headquarters in Newington, Connecticut;
and July 13-16 at the Dayton Amateur Radio Association in Dayton,
Ohio. The 5-day advanced (TI-2) seminar, "Remote Sensing and Data
Gathering," will be held July 20-24 at ARRL Headquarters. The TI-2
session is only open to those who have already completed the TI-1
program.
"As our nation looks toward an increasingly high-tech future, our
educational system must improve the preparation of our students in the
areas of science, technology, engineering, and mathematics (STEM),"
said ARRL Education Services Manager Debra Johnson, K1DMJ. "Teachers
and schools are looking to meet these expectations by providing
students with opportunities for hands-on, project-based learning."
Teachers at the 2014 Dayton TI-1 session assemble the Boe-Bot® robot,
which they will use to learn microcontroller programming and robotics.
Johnson said the expenses-paid Teachers Institute sessions offer
educators a professional development opportunity that equips them with
training and resources to explore a variety of applications in radio
science and wireless technology and -- in the advanced seminar --
remote sensing and data-gathering techniques.
ARRL Teachers Institute is open to grade 4-12 teachers as well as to
post-secondary educators. "We look for teachers who have a vision of
how to apply this wireless technology training to support STEM
learning in their classrooms," Johnson said.
Additional details are in the article, "The ARRL Teachers Institute on
Wireless Technology" in the March 2015 issue of QST. Interested
teachers will find more details and an application on the ARRL
website. Applications are due by May 1.
Amateur Radio Gear, Tools, Supplies Bound for Micronesia in Wake of
Tropical Cyclone
A shipment of ham radio equipment, tools, and supplies will head from
Hawaii to the Federated States of Micronesia (FSM) this week with John
Bush, KH6DLK/V63JB. The radio gear will support communication for
relief efforts as the FSM recover from Tropical Cyclone Maysak, which
ravaged many of the nation's islands in late March and early April,
wreaking major damage and causing some deaths. Bush plans to leave
April 10. Initial plans called for including an ARRL "Ham Aid" kit in
the shipment, but Bush said he's leaving that gear in Hawaii for the
time being, because the building where it was to be set up no longer
exists.

the spectacular Typhoon Maysak from the ISS on April 1 as the storm
continued to spin in the far western Pacific Ocean. [NASA photo]
"While many agencies and nations are responding, it's just not
enough," said ARRL Hawaii Section Manager Bob Schneider, AH6J. The Ham
Aid gear had been shipped to Hawaii last fall, as the massive Puna
volcanic lava flow threatened some communities on the Big Island of
Hawaii. It includes both HF and VHF gear.
With a population of about 103,000, FSM is comprised of four states
over 600 islands -- about 1800 miles from end to end. Typhoon Maysak
struck Ulithi Atoll with 160 MPH winds, with gusts to 195 MPH -- a
Category 5 storm. A major storm surge of unknown height also hit, and
infrastructure on all islands, including schools, homes, and the power
and telecommunication systems, suffered major damage or were destroyed
altogether.
"Local communications have been heavily impacted by the storm, and
some areas are still cut off and have not been heard from," Schneider
told ARRL.
Two FSM hams, William Radolfetheg, V63YWR -- an elementary school
principal on Federai Island, part of Ulithi Atoll -- and Albert,
V63YAG, were off the air since before the typhoon hit and had not been
heard from until April 6, when V63YWR came on the air using a depleted
battery and at very low power.
The ARRL is a member of Hawaii State VOAD, an organization of
non-governmental organizations that provide disaster relief. Other
organizations pitching in include church-affiliated groups, the Red
Cross, The Salvation Army, the International Organization for
Migration, USAID, and Pacific Missionary Airlines.

Federai Island, part of Ulithi Atoll.
Bush and Schneider have been assembling an assortment of loaned and
donated radio equipment, antennas, tuners, power supplies, tools,
hardware, "suitcase" solar panels, and FAA-legal gel cells for
"bare-bones power" to send to the stricken region. As a result, the
shipment could mean as many as a dozen extra bags; negotiations are
under way with Hawaiian Airlines to reduce or waive excess luggage
fees. Private donations amounting to approximately $3000 have been
received, and most of those funds will go toward fuel for the Pacific
Missionary Airlines leg of the trip. Barbara Darling, AH7G/NH7FY,
sponsored the 100 W portable photovoltaic system.
"This preparation to provide emergency communications has occurred in
just 9 days but has the complexity of a major DX expedition," Bush
said. "If everything goes well, we should be on 14.335 at 0700 UTC and
possibly on 21.335 at 2100 UTC each day."
"Look for us, but please don't interrupt if vital communications are
in progress," Schneider stressed. "This is not a DXpedition!" Read

ARRL Rookie Roundup Returns: SSB Event is Sunday, April 19!
The SSB version of ARRL Rookie Roundup returns on Sunday, April 19.
The event gets under way at 1800 UTC and continues through 2359 UTC.
For the purposes of this operating event, a "Rookie" is any radio
amateur licensed within the current calendar year or in the previous
two calendar years, regardless of license class. Rookie Roundup events
take place three times a year: SSB in April, RTTY in August, and CW in
December.
From left to right, KJ6PUO, KK6CWV, and KJ6PUN operate Rookie Roundup
2013 at Stanford University's W6YX.
The goal of Rookie Roundup is to encourage recently licensed operators
in North America (including territories and possessions) to operate on
the HF bands and experience competitive Amateur Radio operating.
Experienced operators are encouraged to participate and help new
operators -- either on the air or in person. Old Timers may want to
consider opening up their stations to rookies and serving as
contesting mentors. The more operators on the air, the more fun the
Roundup will be for everyone.
Rookies call "CQ Rookie Roundup," while veteran ops call "CQ Rookies."
Exchange the call sign of the station you're working, your call sign,
your first name, the two-digit number of the year first licensed, and
your state, Canadian province, Mexican call area, or DX.
Rookie Roundup participants can log the contest using contest logging
software the supports the event, paper forms provided on the Rookie
Roundup web page or by using the real-time In The Log website. Once
the contest is over and you've calculated your score, complete the
Rookie Roundup Online Score Submission Form to submit your score; no
logs are necessary. Entrants must fill out this form to enter, and all
entries are due within 72 hours (3 days) of the end of the contest.
Contact ARRL Contest Branch Manager Matt Wilhelm, W1MSW, for more
information. Read more.
Slow-Scan TV Transmissions from ISS Scheduled for April 11
Amateur Radio on the International Space Station (ARISS) has announced
that slow-scan television (SSTV) transmissions are planned for
Cosmonautics Day, Saturday, April 11 from RS0ISS in the ISS Russian
sector. Cosmonautics Day celebrates space pioneer Yuri Gagarin's April
12, 1961, as the first human to reach space.
An SSTV image from the ISS, successfully received in October 2014 by
N4ZG.
The SSTV event will get under way on April 11, 1000 UTC on 145.800 MHZ
and continue until 2130 UTC. All transmissions will use SSTV mode
PD180 (enable "Always show RX viewer" or use "Picture viewer"
(magnifying glass icon) to display in 640 × 496 resolution). If
similar to prior SSTV events, 12 different photos will be sent through
the weekend with 3-minute off periods between transmissions.
Receiving the SSTV images requires a 2 meter receiver/transceiver and
a PC to convert the audio to an image. Software such as MMSSTV (set
sound card audio sampling to 48 kHz) is available for free on the
Internet (iOS SSTV App). Received images may be uploaded and viewed at
the ARISS Image Gallery.
Unanticipated events on board the ISS may cause any scheduled ham
radio event to be postponed or cancelled. Check the ARISS Facebook
page for updates. The ISS Fan Club website can show you when the ISS
is within range. Visit the ARISS SSTV Blog and Gallery.
TEN-TEC and Alpha Change Hands
Less than a year after TEN-TEC and Alpha Amplifiers merged under the
RF Concepts banner, the companies have changed hands again. RKR
Designs LLC of Longmont, Colorado, announced on April 2 that it had
acquired the two brands' assets from RF Concepts. RKR said it plans to
expand the product line while "continuing to service their customers."
RKR Designs principals are Ken Long, N0QO, Richard Gall, and Rich
Danielson. Long, with more than 20 years in the electronics and
Amateur Radio industries, will be president and CEO of the new
company. Gall and Danielson of QSC Systems in Longmont have been a
successful contract manufacturer for over 20 years. QSC has been
building Alpha amplifiers for more than 5 years, and boards for
TEN-TEC since RF Concepts bought the company last year.
RKR Designs LLC is privately held, and the terms of the acquisition
were not disclosed. Read more.

WWV's 25 MHz Signal Still Going Strong After 1 Year Back on the Air
Time and frequency standard station WWV silenced its 25 MHz signal in
1977, but it returned to the air on an "experimental basis" a year
ago, and it's still up and running. Resurrecting the long-dormant
standard time outlet operated by the National Institute of Standards
and Technology (NIST) was Matt Deutch, N0RGT, WWV's Lead Electrical
Engineer.

"We have been at 1 kW for the past year," Deutch told ARRL. "We have
had a few hiccups, but nothing serious." Deutch said he was pleased to
see the 25 MHz signal included in a recent QST article, "just like the
good ol' days" (see "Measuring Frequencies at VE3GSO," in the April
2015 issue of QST, p 37).
"Here at the site we have even been discussing giving the 25 MHz
signal its own antenna again," Deutch said. "The ham in me wants to
give it something more exotic than a plain ol' boring dipole. But what
antenna could it be?" Deutch said he was inspired by the article
"Amateur Radio Science" by Eric Nichols, KL7AJ, in the February 2013
issue of QST, which asked hams to do more to advance and contribute to
the radio art, "but the gears in my brain are still turning," Deutch
said.
The return of WWV's 25 MHz outlet came about after Dean Lewis, W9WGV,
lamented its loss last year in an e-mail to Deutch, who surprised him
by putting the signal back on the air, initially temporarily. The 25
MHz signal not only provides another option to check your frequency
calibration or the exact time, it also can serve to indicate the state
of propagation on 12 and 10 meters. Deutch said the WWV 25 MHz signal
still gets signal reports from across the Atlantic.
WWV has invited listeners' comments and signal reports. Read more.

Newer Radio Amateurs Asked to Participate on Online Survey: Kentucky
academic researcher Joel Shelton, N8XJ/A65BX (seen in the photo), is
seeking radio amateurs licensed since January 1, 2000, to take part in
an online survey. The survey is part of a research project. Shelton is
focusing on newer hams because, he said, "I am interested in what
attracts people to take up a century-old hobby for the first time in
the 21st century." Shelton asked that if you fit this category to
complete his online survey. He said he plans to use the survey results
to prepare articles -- one for an academic journal -- about the
current state of Amateur Radio and what continues to attract
newcomers. Contact Shelton for more information. -- Thanks to Joel

Standard General Affiliate Acquires 1743 RadioShack Stores: The
inventory and the leases of 1743 retail outlets that survived
RadioShack's February bankruptcy have been acquired by General
Wireless Inc, an affiliate of Standard General LP. The acquisition
followed an auction, conducted under the US Bankruptcy Code. The
current plan calls for "co-branding" about 1440 of the surviving
stores with cellular phone provider Sprint Corp. RadioShack once
offered entry-level shortwave receivers, Citizens Band gear, a wide
array of discrete components -- including transistors, resistors, and
capacitors -- and, for a time, 10 and 2 meter Amateur Radio gear.
RadioShack said its stores would feature "emerging technologies that
enhance the traditional accessories, DIY electronics and innovation
for which the company is known."
Oklahoma Radio Amateurs to Conduct Digital Test: Amateur Radio
operators in Oklahoma will take part in the year's first statewide
Automatic Packet Reporting System (APRS) net at 0800 UTC (1 PM CDT)
Saturday, April 11. The Tulsa Digital Radio Club (KT5DIG) is
sponsoring this event. This is an opportunity for radio amateurs to
exercise their APRS station by sending and receiving APRS messages as
well as the more common position reports. "More and more Amateur Radio
operators are using APRS on their smartphones," said Oklahoma Section
Manager Lloyd Colston, KC5FM. Oklahoma hams are encouraged to monitor
the net activity and provide reception reports of stations heard on
144.390 to Scott Haley, KD5NJR. Monitor the APRS activity online.
The K7RA Solar Update
Solar activity continues to weaken. Average daily sunspot numbers
dropped 27.8 points to 50.1 over the April 2-8 period, compared to the
previous 7 days. Average daily solar flux declined 17.3 points to
118.4 over the same period.
The latest prediction has solar flux at 110 on April 9, 115 for April
10-16, 145 for April 17-19, 135 on April 20, 130 for April 21-22, 125
on April 23, 120 on April 24, and 125 for April 25-26. Solar flux
drops to 115 for April 30 through May 2, then rises to 145 for May
7-10.
The same prediction has planetary A index at 20, 15, and 8 for April
9-11, 5 for April 12-14, then 12, 20, and 15 for April 15-17, 20 for
April 18-19, 12 for April 20-21, 8 for April 22-24, 25 on April 25,
and 29 for April 26-27.
These predictions are revised daily, and come from 45-day forecasts
from NOAA. My archives of these predictions, with planetary A index
and solar flux now are available as Microsoft Excel spreadsheets. I
hope to update these often. They show how the solar flux forecasts
have been weakening over time.
At 2346 UTC on April 8, Australia's IPS Radio and Space Services
issued a geomagnetic disturbance warning for April 9-10, due to a CME
and solar wind from a coronal hole. Geomagnetic conditions may be at
active levels over the 2-day period.

Getting it Right...Side Up
Several e-mails informed us that the photo of recent FCC retiree Bill
Cross, W3TN, in The ARRL Letter of April 2, 2015, was upside down and
thought it may have been a belated April Fool's Day prank. It was not.
As it was received, the photo had to be reoriented for publication.
Some e-mail clients do not recognize the exchangeable image file
format (EXIF) "tag" that indicates a photo has been rotated, however,
and will display the image in its native orientation. This particular
problem seems to prevail among gmail.com users.
