AMSAT Echoes IARU Satellite Coordination Concerns
AMSAT-NA has joined the International Amateur Radio Union (IARU) in
expressing concern that some soon-to-be-launched satellites operating
in Amateur Radio bands could cause conflicts in some ITU regions. In
an August 7 statement on behalf of the IARU, Secretary Rod Stafford,
W6ROD, said the IARU had become aware of plans to launch a series of
satellites, "where the frequencies proposed appear to conflict with
existing IARU band plans" in parts of the world.
"IARU is investigating how this has arisen, and is discussing the
issues with the parties involved," Stafford said. AMSAT-UK has
reported that the IARU Satellite Coordinator was asked to look into
the matter.
While Stafford did not name any specific satellites that may be of
concern, AMSAT-UK has said that some frequencies proposed for the
Chinese Amateur Radio Group (CAMSAT) XW-2/CAS-3 mission do not respect
the internationally agreed-upon 2 meter band plan for IARU Region 1.
AMSAT-NA President Barry Baines, WD4ASW, told the ARRL that AMSAT's
initial excitement regarding the pending CAMSAT launch of nine Amateur
Radio satellites has been tempered by concerns that some of the
proposed amateur frequencies may not have been properly coordinated.
"While these frequencies are within the spectrum allocated for the
Amateur Satellite Service, several will conflict with existing
terrestrial allocations, as well as with the normal voice and SSTV
downlink from the ISS," Baines told ARRL. "We support the IARU's
effort to determine how the lack of coordination occurred, to mitigate
the interference issues to the maximum amount possible, and to ensure
that future amateur satellites will be coordinated in accord with
established norms for the benefit of all."
In a related matter, also alluded to by Stafford, the operation of an
existing satellite -- the 14-year-old PCSAT (NO-44) -- recently became
a problem over Europe, when it began transmitting APRS on 144.390 MHz,
due to technical issues related to its age. APRS on that frequency is
not compatible with the Region 1 band plan. "[T]his unfortunate
circumstance appears to be unintentional," Baines allowed in his
comments to ARRL. "There are lessons to be learned in satellite design
from this experience that will hopefully be followed in the future to
mitigate such potential problems," Baines added. Users have been asked
not to digipeat via PCSAT while the satellite is over Europe.
With the support of the International Telecommunication Union (ITU),
IARU volunteer satellite coordinators assign appropriate frequencies
for satellites designed to operate on Amateur Radio frequencies.
Stafford said these efforts have generally been successful, "allowing
satellites to operate without undue interference to each other and to
other services using the bands in question." -- Thanks to IARU, AMSAT,

ARRL Teachers Institutes Chalk Up Another Successful Summer
Educators from several states expanded their electronic horizons this
summer in three ARRL Teachers Institute on Wireless Technology
sessions. The 2015 ARRL Education & Technology Program (ETP) offered
two introductory (TI-1) and one advanced (TI-2) Teachers Institute
sessions this summer.
TI Instructor Tommy Gober, N5DUX, demonstrates how to operate via an
Amateur Radio satellite.
"I am the only teacher in my building who teaches Ohm's Law and basic
electricity, along with breadboard circuits, because of what I learned
at the first TI," one advanced student commented afterward. "From this
TI, I feel like I have 'upped' my game."
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.
A 4-day introductory (TI-1) session in June at Parallax in Rocklin,
California, kicked off the series. An additional introductory course
was held in July at ARRL Headquarters. A 5-day advanced (TI-2)
seminar, "Remote Sensing and Data Gathering," took place in late July
at ARRL Headquarters. The advanced course is only open to those who
have already completed the introductory program; an Amateur Radio
license is a prerequisite.
At the California TI-1 class, instructor Tommy Gober, N5DUX, plunged
into some hands-on radio activities, which included working a couple
of stations via SaudiSat 1-C (SO-50) and capturing part of a NOAA
weather satellite pass. Groups of class participants in both sessions
also faced off in a hidden-transmitter hunt -- a fox hunt.
TI students run their BoeBots through a maze to check on how well
they've mastered the required programming skills.
The TI-1 students also learned computer programming to control
Boe-Bot® robots on wheels that they then run through a maze to check
their coding skill.
In the TI-2 class, expanded to 5 days to cover applications for
downloading and using satellite telemetry as well as electronic
sensors and their deployment in a marine buoy. Participants also used
a MAREA (Mars Lander Amateur Radio Robotics Exploration Activity)
transceiver to outfit their Boe-Bots for packet control. The robot
activity simulates how NASA scientists use radio signals to control
the Mars rovers. TI Instructor Matt Severin, N8MS, demonstrated
techniques to use satellite data in the classroom by downloading
telemetry from the FUNCube-1 (AO-73) educational spacecraft. TI-2
participants also were exposed to digital concepts, such as
analog-to-digital conversion.
Among the 22 attending the two TI-1 courses, 11 had Amateur Radio
licenses, while nine others indicated they intended to get their
tickets. Ten radio amateurs participated in the TI-2 class.

remote-sensing techniques. [Debra Johnson, K1DMJ, photo]
"We are all teachers and deal with a lack of time, money, and
authorization issues, but we do have the ability to integrate ideas
that can profoundly change the way students understand data and
technology," TI Instructor Bill Richardson, N5VEI, remarked.
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," said ARRL Education Services Manager
Debra Johnson, K1DMJ.
World-Circling Danish Radio Amateur-Cyclist Now in the US
Danish radio amateur Thomas Andersen, OZ1AA/K9DXX, has said he never
wanted to think back on things that he might have done during his
lifetime, but did not. That's why he decided to follow his dream and
start cycling -- around the globe. He's now completing the 5th year of
his journey, and he's been meeting many hams along the way. This month
he's been working his way up the East Coast of the US, more or less
following US Route 1 from Florida.
OZ1AA set out on his bicycle from Copenhagen in 2010.
"I have been staying with hams almost every day on the trip in the
US!" the 32-year-old telecommunications engineer told ARRL this week.
"Absolutely amazing hospitality." He plans to end the North American
leg of his trip in St John's, Newfoundland. "From there I will be
flying back to Denmark for a 3-month break," he explained. "Then my
plan is to go to Africa and start riding home from there."
Andersen said his bicycle adventure also stemmed from a desire to
attempt something that he was not entirely sure he could finish, but
it's been an opportunity to combine his favorite activities.
"Apart from ham radio I have been interested in cycling since I was a
kid," he said on his QRZ.com page. "I also love to travel, so it was
somewhat natural for me to combine my passions in life into a perfect
match." Andersen has been pedaling since leaving his homeland in 2010.
His initial plan was to cycle southeast and end his trip in Sydney,
Australia.
OZ1AA stops in Washington, DC, on his way up the US East Coast.
"When I left Denmark I had enough money for 1 year of travelling (on a
$20 a day budget). That was enough to get me to Australia," he told
ARRL. "I thought I had to go back home from there, but I found work in
Australia -- on a huge cattle station out of Alice Springs -- so I
could save up more money and extend my trip to the Americas as well."
He now hopes to complete his circumnavigation back home in Denmark.
So far, he has not been carrying along any Amateur Radio gear, because
of weight concerns. "Even so, I have come to the conclusion that I
would like to add a small HF rig to my setup. Having a radio in my bag
simply seems worth it," he said on QRZ. Andersen said he thinks his
adventure would not have been possible without his being a radio
amateur.
"I can't honestly think of any other hobby where you can show up in
any town in any part of the world and be welcomed like I have been. He
said his non-ham friends don't get it, though. "[B]ut all I can tell
them is: Become a ham, and you will have 1 million friends around the
world as well." Read more.

Joint Cuba-US DX Operation Planned; Will Include CQ World Wide SSB
Contest
In the wake of the recently announced normalization of diplomatic
relations between the US and Cuba, a joint US-Cuba operation is being
planned for this fall, to include the dates of the CQ World Wide SSB
contest.
"The combined group will be operating under the call sign T42US
between October 21 and October 28, including during the CQ WW DX SSB
Contest," the announcement said. "There will be nine operators from
the USA and approximately the same number from Cuba. The T42US group
will operate 160-10 meters, SSB and CW."
The US Team leader is Jim Millner, WB2REM, and the Cuban Team Leader
is Bob Ibarra, CM2KL. Millner said the T42US operation will be among
the first of its kind in Cuba and will involve a joint effort between
the US and Cuban teams. Read more.
Texas Club Donates $1000 to Support Amateur Radio Parity Act of 2015
Campaign
The Temple Amateur Radio Club (TARC) has again generously supported
the ARRL's advocacy efforts, this year donating $1000 to the
Legislative Issues Advocacy Fund in support of the Amateur Radio
Parity Act of 2015. In the past, the Texas club has donated to the
Spectrum Defense Fund, but this time it asked specifically to put its
gift toward the Parity Act campaign.
"The Temple Amateur Radio Club has been a long-time supporter of
ARRL," said ARRL Development Manager Lauren Clarke, KB1YDD. "Over the
years, the club has donated $8000 to the Spectrum Defense Fund to
support ARRL advocacy efforts to protect our frequencies. We are
grateful to the members of TARC for their continued support and
generosity."

Representatives of the club presented a check to ARRL West Gulf
Division Director Dr David Woolweaver, K5RAV, and Vice Director John
Stratton, N5AUS, at the ARRL South Texas Section Convention -- the
Austin Summerfest -- August 7-8. ARRL Marketing Manager Bob
Inderbitzen, NQ1R, who represented League Headquarters at the event,
said some 700 visitors turned out for the convention, despite
temperatures in excess of 100° F.
During the ARRL Forum, attended by about 120 conventioneers,
Inderbitzen said Director Woolweaver encouraged those on hand to
support the Amateur Radio Parity Act grassroots effort to obtain
additional cosponsors for the US House and Senate bills.
TARC maintains two repeaters under its W5LM call sign, and actively
participates in public service events. The club sponsors the HamEXPO,
held this year on October 3 in Belton, Texas.
ARRL Rookie Roundup RTTY is August 16
The ARRL Rookie Roundup returns to RTTY Sunday, August 16, 1800 UTC
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 2 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.
KK4EVI and KK4JRP learn RTTY contesting techniques during the 2012
ARRL Rookie Roundup with the Charleston Amateur Radio Society.
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.
During the contest Rookies can work anyone, while veteran operators
only work Rookies. Single-Operator Rookie entrants can form teams, but
teams must register beforehand. A multioperator category is also
available for stations hosting more than one Rookie operator. Rookies
call "CQ RR" (CQ Rookie Roundup), while veteran ops call "CQ R" (CQ
Rookies). Exchange the call sign of the station you're working, your
call sign, your first name, two-digit number of the year first
licensed, and your state, Canadian province, Mexican call area, or DX.
Review the rules before the event, and get familiar with logging and
log submission processes too. Rookies exchange information with as
many other stations as possible on 80, 40, 20, 15, and 10 meters.
Before venturing forth, Rookie entrants are encouraged to read "HF
Contesting -- Good Practices, Interpretations and Suggestions."

WWV's 25 MHz Signal is Back on Original Vertical Dipole
Time and frequency standard station WWV's resurrected 25 MHz signal --
now back on the air for more than a year after going silent in 1977 --
is once again transmitting on a vertical dipole from its original
antenna and location. The 25 MHz signal returned to the air on an
"experimental basis" in April 2014, and it's been transmitting ever
since. The WWV vertical dipole is not something you'd likely find in
the average ham radio antenna farm.

Deutch, N0RGT]
"The antenna the 25 MHz [transmitter] is on right now is the original
antenna it was on in 1977," Matt Deutch, N0RGT, WWV's lead electrical
engineer, told ARRL. "When the 25 [MHz transmitter] was shut down
[that year], the radiating section was removed and tossed in the bone
yard, and a new longer section put on the tower to make it a 15 MHz
stand-by antenna."
Deutch said that when WWV first reintroduced the 25 MHz broadcast in
2014, it used a broadband monopole. It was later decided to use that
antenna for WWV's 2.5 MHz stand-by transmitter, though. "So, we
decided to rebuild the 25 MHz antenna," he recounted. "A few weeks ago
the boys dug the 25 MHz radiating section out of the mud in the bone
yard and rebuilt the 25 MHz antenna, so that it looks identical to
what it looked like in 1977."

Deutch said the 25 MHz WWV vertical dipole now is coupled to its own,
dedicated transmitter, radiating 2.5 kW "with near zero watts
reflected," he added, and modeling has showed that the dipole exhibits
a lower angle of radiation than the broadband monopole did. "There is
no automatic backup transmitter for 25 MHz at this time," Deutch
added. The 25 MHz WWV signal had been operating at about 1 kW for the
past 16 months.
Deutch has said that WWV has received reports on the 25 MHz signal
from across the Atlantic. The 25 MHz transmission 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. The 25 MHz broadcast includes the same information transmitted
on all other WWV frequencies and at the same level of accuracy.
Located in Fort Collins, Colorado, WWV is operated by the National
Institute of Standards and Technology (NIST). WWV has invited
listeners' comments and signal reports.
Rockwell Collins to End Mechanical Filter Production
As more and more communications equipment designs have adopted digital
signal processing techniques, Rockwell Collins has announced that it
will stop manufacturing its renowned mechanical filters. It did not
provide a specific date.
"Over the past several years, we have seen a dramatic reduction in
demand for narrowband analog filters," the company said on its
website. "Due to this and other economic reasons, [Rockwell Collins]
Filter Products will be discontinuing its mechanical filter products
in the near future."
Rockwell Collins makes two different types of mechanical filters, many
of which have found their way into Amateur Radio products and
applications. In a mechanical filter, input and output transducers
convert the electrical signal to and from resonant mechanical
vibrations, respectively.
Collins has made mechanical filters for more than 6 decades, and their
initial application was in telephone circuits. The filters gained
favor for Amateur Radio use because of their excellent selectivity,
especially in IF applications. It is said to take about 12 weeks to
manufacture a single unit. Read more. -- Thanks to Mike Morris,

Central States VHF Society Honors Wayne Overbeck, N6NB; Lauren Libby,
W0LD
The Central States VHF Society (CSVHFS) recently honored two radio
amateurs with awards. Wayne Overbeck, N6NB, was presented with the
Society's 2015 John Chambers Memorial Award, and Lauren Libby, W0LD,
received the 2015 Wilson Award. Kent Britain, WA5VJB, presented both
honors on July 25 at the CSVHFS annual conference in Denver.
The Chambers Award is given for technical contributions to VHF/UHF
Amateur Radio. Created in 1970, it honors the memory of John Chambers,
W6NLZ, who completed the first-ever 2 meter transpacific contact with
Ralph "Tommy" Thomas, KH6UK. The Wilson Award is given for outstanding
service to the CSVHFS or for service to VHF-UHF Amateur Radio in
general. Introduced in 1982, it honors the memory of Mel Wilson,
W2BOC.
This marked the second time that Overbeck has won the Chambers Award,
although it's been a long time between awards; he previously won it in
1978.
Overbeck and Libby said they were pleased and surprised to be feted at
the conference. In presenting the awards, Kent Britain, WA5VJB, said
Overbeck was being honored for accomplishments since winning his
previous Chambers Award in 1978, and primarily for his success in
setting new world DX records on the 2.3 and 3.4 GHz bands. Libby
received the Wilson Award for his longtime service to the CSVHFS.
Katrina 10th Anniversary Mississippi Memorial Event Set
A special event operation from August 26 through September 2 will
commemorate the 10th anniversary of Hurricane Katrina and the more
than 230 people who lost their lives as a result of Katrina along the
Mississippi Gulf Coast and points north.
"Many lost everything they owned and many lost their lives," said
Larry Morgan, AG5Z, who is spearheading the event. "We also want to
honor the hundreds of volunteers from all over the country that poured
in to assist us in our time of dire need."
Hurricane Katrina damage in Gulfport, Mississippi.
Several stations along the Mississippi coast will use special event K
(for Katrina) prefix 1 × 1 call signs. Operation will begin on August
26 at 0000 UTC from home stations. On August 29 at 1300 -- the time of
Katrina's impact -- all stations will reduce power to 100 W, except
for bonus stations K5M and K5T. Reduced-power operation will continue
until September 2 at 2359 UTC.
K5Z at "ground zero" will consist of a portable QRP station set up on
the beach using temporary antennas and emergency power.
Certificates will be available. See the Katrina 10th Anniversary
Special Memorial Event website for details. Send logs and QSLs to
AG5Z. Morgan expressed his appreciation to the 599 DX Association and
the Hattiesburg Amateur Radio Club. Read more.
