Hams Provide Emergency Communications in Australia, Puerto Rico


Ham radio is once again proving to be a vital communications resource in disasters, with amateurs supporting relief efforts for both Australia's wildfires and the series of earthquakes that rocked Puerto Rico in January. The ARRL Letter reports that hams in Australia were working with the New South Wales Volunteer Rescue Association in support of the Rural Fire Service. In addition, the Wireless Institute of Australia reports that most of the amateur repeater network in the state of Victoria is off the air, due to a combination of power outages and direct fire damage.


In Puerto Rico, hams are working with the American Red Cross, primarily on the southern part of the island, which has suffered the greatest earthquake damage. In addition, the ARRL reported that it was shipping six VHF/UHF repeater antennas and six 50-foot rolls of LMR-400 coax to help re-establish reliable communications. 

At press time, the earthquakes and aftershocks in Puerto Rico were continuing, as were the massive wildfires in Australia.

Ham Bands Under Threat in US, China, and Worldwide

The FCC has proposed withdrawing the amateur radio allocation on 3.3-3.5 GHz to make more spectrum available for mobile broadband and the International Telecommuni- cation Union will consider a proposal to reallocate some or all of the 10-GHz band at the next World Radiocommunication Conference in 2023. Both of these proposals are discussed in detail in February's VHF-Plus column.

In addition, the ARRL Letter is reporting that China has proposed major cuts to amateur allocations there, including the 2200-meter band, 146-148 MHz, 1260-1300 MHz, 3400-3500 MHz, 5650-5725 MHz and all frequencies above 10 GHz. Alan Kung, BA1DU, the CEO of China's amateur satellite organization, told the ARRL it is unlikely that all of the proposed reallocations will be finalized but conceded that pressure on spectrum space in China and around the world will continue.

Promising Signs from Ol' Sol

Two more Cycle 25 sunspots appeared on the surface of the Sun in late December, providing reassurance that there will be a new cycle and that we are not likely to be stuck in an extended solar mini- mum. This is in line with an updated international forecast for Cycle 25 issued in early December.

The ARRL quoted solar researcher Tony Phillips as saying that the current minimum is "deep" and "century-class according to sunspot counts," but that the new sunspots "suggest that the solar cycle is, in fact, unfolding normally," and that a new Maunder minimum does not appear to be in the offing.

Electricity Underfoot!

apparently passed through a fold in the interplanetary
magnetic field. (Graph courtesy Rob Stammes /

CQ Propagation Editor Tomas Hood, NW7US, will be discussing in his February column the interplanetary magnetic field (IMF) on which the solar wind travels, and the fact that it resembles a wavy sheet, with a positive polarity on one side and a negative polarity on the other. When the Earth passes through one of these waves, it results in a quick flip-flop of the field's polarity as measured here, and that can have significant effects here on the ground. An apparent example occurred early this year.
 
Spaceweather.com reported that, on January 6, electrical currents began flowing through the ground in Norway. Researcher Rob Stammes of the Polarlightcenter geophysical observatory (<www.polarlightcenter.com>) reported measuring "a sudden strong variation in both ground currents and our local magnetic field" (see graph). Just 15 minutes earlier, according to the spaceweather report, NASA's ACE spacecraft detected a five-fold increase in the density of the solar wind and a 180-degree shift in the IMF's polarity. It was speculated that Earth had just passed through a fold in the heliospheric current sheet. 

These ground currents can cause significant problems here on Earth. Professor Louis Lanzerotti of the New Jersey Institute of Technology, an expert in the field, wrote on the HamSCI e-mail reflector that such currents have caused major power blackouts, such as the one that hit Quebec in 1989, as well as failures in undersea phone cables. 

The January 6 event also touched off auroras over Scandinavia. They were visible in Finland, but Stammes reported that the skies over his observatory in Lofoten, Norway, were cloudy so "we had to be satisfied with the electricity underfoot."


FCC Proposes Massive Fine for Pirate Broadcasting


The FCC continues its enhanced enforcement campaign against unlicensed broadcasters on the FM band, proposing a fine of more than $450,000 against Gerlens Cesar, operator of Radio TeleBoston. According to the ARRL Letter, the FCC said Cesar was operating three separate transmitters and broadcasting on both 90.1 and 92.1 MHz. The Commission said the proposed fine – the largest ever proposed for a pirate broadcaster – came after it had issued multiple warnings.

Milestones: KC9ZJX Honored; A41AA SK

Newsline's 2019 Young Ham of the Year has been honored by his hometown. Dhruv Rebba, KC9ZJX, is among four recipients of the annual Martin Luther King, Jr. award issued by the Bloomington and Normal (Illinois) Human Relations Commissions.

According to local radio station WGLT, he was recognized for his volunteer work with a number of organizations, including the Multicultural Leadership Program, the National Computer Science Honor Society and First Robotics. The AMSAT News Service noted that Rebba is also the recipient of the AMSAT Presidential Award.


The Sultan of Oman, Qaboos Bin Said, A41AA, became a Silent Key on January 10 at age 79. The ARRL reports that he was the patron and sponsor of the Royal Omani Amateur Radio Society and its club station, A47RS. Bin Said had been the country's ruler since 1970.

IARU Region 2 Restarts Intruder Watch


Region 2 of the International Amateur Radio Union (IARU), covering North and South America, has restarted its monitoring system program, watching for non-amateur intruders on amateur radio frequencies. The Region 1 monitoring system (Europe, Africa and the Middle East) has been quite active in identifying stations that don't belong on the ham bands and working to get them to change frequencies, but there has been no similar activity on this side of the Atlantic in recent years. The effort is being restarted by LU1BCE, who encourages all amateurs in the Americas to participate through their national societies.

First Shipment of New Ham Gear OKd for Launch to ISS

Space Station. Two matching units are scheduled to be
launched this year. (Courtesy ariss.org)
The International Space Station will be getting new gear for its ham station over the course of 2020, the culmination of a years-long effort called the Interop- erable Radio System, or IORS.

The AMSAT News Service reports that NASA has given its safety approval to the first shipment of gear and accepted delivery of the equipment for inclusion on board an upcoming SpaceX supply launch.

The IORS consists of higher-powered radios, an enhanced voice repeater, updated APRS packet capabilities and slow-scan TV equipment for eventual installation in both the space station's Columbus module and the Russian service module.

Multiple YOTA Camps Planned in Europe This Year


Europe's Youngsters on the Air (YOTA) program cele- brates its tenth anniversary this year with multiple camp opportunities for young hams. The main YOTA camp in 2020 will be held in Croatia, with smaller "subcamps" also planned for Serbia and Norway. According to the IARU Region 1 organization, which is YOTA's prime sponsor, young hams from across the region are encouraged to apply. The costs for individuals are kept very low (roughly 25 Euros) with the sponsoring organizations and donors providing the bulk of the support.


A YOTA camp is scheduled in North America for the first time this June. See following story or visit <http://youthontheair.org>.

Over 12,000 QSOs for YOTA Month Ops in the Americas


Youth on the Air Month each December encourages young hams around the world to get on the air and make lots of contacts, both with other young hams and older ones as well. The idea started in Europe, where the International Amateur Radio Union (IARU) Region 1 organization has made a concerted effort to promote ham radio to young people (see previous story). In 2019, there was also an organized effort in the Americas (IARU Region 2) in conjunction with the upcoming YOTA Camp this June in Ohio.
 
Organizer Neil Rapp, WB9VPG, and YOTA Month coordinator (and 2018 Newsline Young Ham of the Year) Bryant Rascoll, KG5HVO, report that 18 hams under age 25 in both North and South America used special call signs to draw attention to the activity and made a combined total of more than 12,000 contacts.

In the U.S., 15 young operators around the country alternated using four different 1x1 special event call signs, K8Y, K8O, K8T and K8A (YOTA) on SSB, CW, digital modes and satellites, racking up nearly 10,500 QSOs. In Canada, David Samu, VE7DZO (featured on CQ's November 2019 cover) made over 450 contacts as VE7YOTA, all on CW. Down south, young Chilean amateur Mathias Acevedo von Frey, CE2LR, operated XR2YOTA and one highlight for him was meeting another local young ham, Manu Antonio Pardo Rivas, CA3MPR. Their combined QSO total was over 1500 contacts. Overall, the various YOTA Month stations on both continents logged 12,467 contacts. Around the world, 48 special-call sign stations operated by young hams made nearly 129,000 contacts during YOTA Month.

 For the first time since 1956, amateurs in Tunisia are being granted personal licenses and individual call signs. According to Southgate Amateur Radio News, the first three licenses were recently issued to 3V8HB, 3V8MN and 3V1MB. Until now, Tunisian hams were allowed to operate only from an authorized club station. The process for obtaining an individual license is reportedly quite involved.

Secret Russian Satellite Carrying Ham Transponder May Have Exploded


(Image by Jose Furtado, via Wikimedia Commons)
A top-secret Russian military satellite thought to also be carrying the RS-46 amateur radio transponder is missing and may have exploded in orbit, according to a British news site. A report from "Metro" quotes an astronomer at the Harvard-Smithsonian Center for Astrophysics as saying that the Kosmos-2491 spacecraft, launched in 2013, most likely blew up, either intentionally or accidentally. There had been speculation that the satellite was actually an experimental space weapon of some type.


According to Metro, astronomer Jonathan McDowell wrote on Twitter that in late 2013, "Russia launched a Rokot vehicle with three military communications satellites and a fourth, initially unannounced, payload, later acknowledged with the cover name Kosmos-2491 and associated with the RS-46 amateur radio payload ... It appeared to end its mission in 2014." 

"However," McDowell continued, "at about 1321 UTC on 2019 Dec 23, the satellite made a 1.5m/s orbit change and 10 debris objects have now been catalogued."

McDowell speculated that the satellite may have been destroyed either intentionally or accidentally, either as a result of colliding with space debris or – more likely, he says – that unused propellant still carried by the spacecraft exploded. He noted that "(r)ocket stages which don't do depletion burns sometimes blow up years later." 

Bottom line for hams: If you're looking for RS-46, it isn't there anymore.

Air Force MARS Restructures


Air Force MARS regions are now
identified as "wings" and "states"
are now "groups," to better align
with the organizational structure of
the Air Force itself.
The U.S. Air Force branch of MARS, the Military Auxiliary Radio System, has realigned its organizational structure to more closely align with that of the Air Force itself. According to an AFMARS news release, previous "regions" are now "wings" and "states" are now "groups," matching the Air Force command structure.


In addition, according to the announcement, the change "moves away from an Amateur Radio volunteer-based network structure that aligned with FEMA and other civilian amateur radio groups to a more defined and structured military network of highly-trained radio operators capable of creating a high frequency network for the passing of encrypted radio traffic across the country." Additional information about Air Force MARS is available by calling 888-778-6277 (MARS).

RAC Adds PEI Section


If you enjoy operating ARRL Sweepstakes, Field Day or the ARRL 160-Meter Contest, you'll want to know that there's about to be one more possible multiplier to work … the Radio Amateurs of Canada (RAC) has created a separate admini- strative section for Prince Edward Island (PEI), which until now has been part of the Maritimes section, along with New Brunswick and Nova Scotia.

The ARRL Letter reports that the change will take effect on April 1, along with a shift in boundaries between two Ontario sections: The City of Hamilton and the Regional Municipality of Niagara, currently in the Ontario South section, will become part of the Greater Toronto Area section.

New VHF/UHF Tropo Records Set in Europe and Africa


D41CV - a special call of the D4C station in Cape Verde,
was at one end of four record-breaking VHF/UHF
contacts in late December and early January.

For all of you who think VHF and UHF are only good for local contacts…

The 2-meter tropo distance record for Region 1 of the International Amateur Radio Union (IARU), which covers Europe, the Middle East and Africa, was broken twice within a week around New Year's. The South African Radio League (SARL) reports that on December 28, GM3SEK in Scotland worked the Monteverde Contest Club station, D41CV, on Cape Verde off the coast of Africa at a distance of 4565 kilometers, or 2386 miles. On New Year's Day, D41CV worked GM0EWX on the Isle of Skye on FT8, a distance of 4776 kilometers or 2968 miles. A combination of remarkable VHF DX conditions across Europe and a sea duct running as far south as western Africa was credited for creating the conditions that made the record-setting contacts possible.

The tropo record for 432 MHz was also broken, twice, in the same time period by most of the same players. SARL also reports that on December 28, GM3SEK also worked D41CV on 432 MHz; and that that record was quickly broken - also on New Year's Day - by G4KUX northern England, who also worked D41CV on 432-MHz FT8 at a distance of 4644 kilometers or 2885 miles. This makes the 432 trop distance record in Region 1 just a little bit less than the 2-meter record.

European Space Agency Issues Challenge to Hams


OPS-SAT satellite (European Space Agency photo)
The European Space Agency (ESA) is asking hams to help it track a new satellite right after launch and is offering an incentive for taking part. The satellite is called OPS-SAT and it's scheduled for launch on December 17. According to ESA, "OPS-SAT is a first-of-its-kind CubeSat dedicated purely to experimentation. It carries a wide variety of advanced payloads allowing ‘Experimenters’ to deploy and test their software and apps in space." You must apply to become an experimenter, but there's a form on the OPS-SAT website.
 
ESA is offering hams an incentive: "The first three radio amateurs to receive at least five correctly decoded frames and submit them to ESA get an exclusive invite to the OPS-SAT Experimenter day in March 2020, as well as a tour of the control facilities and ground stations at ESA in Darmstadt, and of course a certificate."

ARRL Committee Drafting New Antenna Bill


Members of the ARRL board of directors' Legislative Advocacy Committee are working on the wording of a new bill to give amateurs greater antenna rights in communities subject to private land-use restrictions. This would be the successor to the Amateur Radio Parity Act, which did not see final action in Congress amid complaints from many hams that it offered too little protection and might actually make some antenna installations more difficult than the already are. The ARRL Letter reports that committee members have met several times with members of Congress and their staffs as they work on drafting the new bill.

Hams Lose Special Exemptions on RF Exposure Rules


The first major revision of the FCC's RF exposure rules in more than 20 years will result in changes in the way that hams must apply the rules. The ARRL Letter reports that the basic limits remain unchanged, but that amateurs will now be subject to the same standards for evaluating RF exposure as other FCC licensees. The current rules provide a framework specific to amateurs that exempts certain transmitters from the need to conduct evaluations based on their power and operating frequencies [see Section 97.13(c)(1) of the rules]. 

The new rules will replace that framework with a general statement that "amateur licensees may evaluate their operation with respect to members of his or her immediate family using the occupational/controlled exposure limits" already in the rules while potential RF exposure to other people "must be evaluated with respect to the general population/uncontrolled exposure limits." 

The practical impact on most amateurs, according to the FCC, will be negligible, noting that a transmitter that had been categorically excluded from evalution in the past most likely will remain exempt. The ARRL is asking the FCC to provide an online calculator with which to make determinations about RF exposure measurements.

ARRL Executive Committee Meets With FCC


ARRL President Rick Roderick, K5UR; Washington Counsel Dave Siddall, K3ZJ, and several members of the League's Executive Committee met with various FCC officials in Washington in early November. According to the ARRL Letter, topics discussed included the RF exposure rule changes described above, the digital date symbol rate proceeding, expansion of the 60-meter band in accordance with international provisions adopted at the 2015 World Radiocommunication Conference, and the ongoing problem of insufficient enforcement in the amateur bands and the startup of the ARRL's new Volunteer Monitor program.

ARRL and AMSAT to Oppose 3.3 GHz Proposal


The FCC adopted a Notice of Proposed Rulemaking at its December 12
 meeting to provide more spectrum for wireless broadband by removing non-federal users from the 3.1 to 3.55 GHz band. This includes the 9-centimeter amateur band at 3.3-3.5 GHz (allocated to hams on a secondary basis).

In a separate proceeding, the ARRL Letter reports, the Commission also decided to "take a fresh and comprehensive look" at current allocations in the 5.9-GHz band, including a secondary amateur allocation at 5650-5925 MHz. Both the ARRL and AMSAT say they will file comments in opposition to removing any amateur allocations in these bands.

Updated Forecast for Solar Cycle 25 Predicts Solar Minimum This Spring, Maximum in 2025

An international panel of solar experts has released an updated prediction for Cycle 25. The group is chaired by the U.S. National Oceanic and Atmospheric Administration (NOAA) and NASA.

The December 9 forecast update continues the previous prediction that Cycle 25 will be of average intensity and similar to currently-ending Cycle 24. A more specific timing prediction forecasts that official solar minimum between Cycles 24 and 25 will come this April (+/- 6 months) and that Cycle 25 will peak in July, 2025 (+/- 8 months) with a maximum smoothed sunspot number of 115.

The update notes that, if the April 2020 forecast minimum is correct, Cycle 24 will have lasted 11.4 years and will be the 7th-longest on record.


WRC-19: Hams Gain Worldwide Allocation at 6 Meters; New Threat to 10 GHz


The 2019 World Radiocom- munication Conference (WRC-19) in Sharm El-Sheik, Egypt, has concluded with a win for hams who enjoy six meters. The band is now designated for amateur radio use in all three ITU regions, opening the door for future amateur allocations on 50 MHz in additional countries, especially in ITU Region 1 (Europe, the Middle East and Africa). [See previous story below for more details]

However, a new threat emerged at the conference as the delegates agreed on agenda items to work on for the next WRC, in 2023. Among those items is a proposal to study the possible use of several microwave bands for future cellphone use, including 10-10.5 GHz, the 3-centimeter amateur band. The "VHF-Plus" column in the February issue of CQ will discuss these issues affecting amateur microwave bands in more detail.

ARRL Calls on FCC to Dismiss NYU Petition on Encoded Messages


The ARRL says a petition for declaratory ruling about encoded messages on the ham bands should be dismissed. As we reported last month, New York University asked the FCC to issue a declaratory ruling clarifying that its rule prohibiting hams from transmitting "messages in codes or ciphers intended to obscure the meaning thereof" also applies to "effectively encrypted or encoded messages" that "cannot be readily decoded over the air for true meaning." The focus of the petition is Winlink, along with PACTOR and similar modes, in which transmissions can only be decoded by a single linked station. NYU says this makes it difficult for amateurs to self-police.
 
The ARRL response, according to the ARRL Letter, is that the requested ruling would make clear language vague and could actually weaken the current prohibition on "messages encoded for the purpose of obscuring their meaning." The League pointed out that Morse code transmissions are "effectively encoded" even though there is no intent to obscure the meaning of the message, and argues that adopting the proposed changes would hobble "vibrant experimentation with digital techniques."

More Countries Grant Hams Access to 5 MHz Band


A growing list of countries is permitting amateur use of the 5 MHz band, in accordance with a decision made at the 2015 World Radiocommunication Conference. The ARRL Letter reports that Kuwait has opened 60 meters to ham use, Israel has extended a temporary authorization through the end of 2023, and access is under consideration in Australia. Nearly 80 countries now permit some level of amateur access to the 5-MHz band.
 
Here in the US, the ARRL reports that an FCC Notice of Proposed Rulemaking is expected soon on adding the frequency range adopted at WRC-15 to the current five permitted channels. The League has asked that current US power levels (which are higher than the WRC-15 recommendations) be retained, while also keeping current US frequencies in addition to the allocation approved at WRC-15.

She also led the effort that resulted in the launch of STMSat-1, the first satellite ever built by elementary school students. Pore has made presentations, often with her students, at various conferences of space educators and is a member of the ARISS U.S. Education Team that evaluates applications for school contacts via amateur radio with astronauts aboard the International Space Station.

The Carole Perry Educator of the Year Award is sponsored by the Orlando Amateur Radio Club, and is named in honor of legendary ham educator Carole Perry. WB2MGP. Pore will receive her award at the Orlando HamCation in February.



Hamvention® Looks to the (More Expensive) Future


The Dayton Hamvention® has adopted a theme of "Amateur Radio, The Future" for its 2020 show, along with what it describes as a "modest increase" in ticket and booth prices. Citing "the economic pressures to present a show like Hamvention," the Dayton Amateur Radio Association said 2020 ticket prices will increase by $4; flea market spaces will each cost $5 more and inside booths will see a price hike of $30 each. 
 
The "future" theme appears to embrace the past as well, with General Chairman Jack Gerbs, WB8SCT, noting that "as we move to the future, we still enjoy the technologies of the past, from tubes to transistors to chips and, now, microprocessors, ASICS and SOCs." Amateur radio, says DARA, has always played a role in communication developments and will continue to do so in the future.

India's Vice President Introduces News Ham Radio Book


S. Suri, VU2MY, founder and Chairman Emeritus of India's National Institute of Amateur Radio (NIAR), has received some high-powered help in promoting his new introductory book about amateur radio in India, All About Amateur Radio / Ham Radio. Suri presented a copy of the book to Indian Vice President Shri. M. Venkaiah Naidu, who promptly put out a tweet with a photo and commented that the book "highlights the importance of ham radio…" Suri added that the Vice President spent a considerable amount of time with the group of hams, said he had been aware for several years of NIAR and the good work that it has done. The book may be ordered online from Flipkart at <https://tinyurl.com/qkt3jsp>.

IARU Looks to Its Own Future


The president of the International Amateur Radio Union is challenging member societies to make changes needed to keep them, the IARU and amateur radio itself, relevant in the future. According to the ARRL Letter, IARU President Tim Ellam, VE6SH/G4HUA, told the group's administrative council last fall that amateur radio is changing but that the IARU and its member societies are not.

After a lengthy discussion, the participants agreed to work on four major challenges:

  • What is amateur radio?
  • The roles of the IARU and its members
  • Recruitment into amateur radio, and
  • IARU finances

The group also agreed to try to identify and involve younger people who "could take ownership of these topics" in addressing these challenges.

Hams in California Support Terrorist Response Drill


Ham radio played a significant role in a major terrorist response drill in southern California in early November. The ARRL Letter reports that some 70 ham volunteers were deployed to 30 hospitals, clinics and emergency operations centers during the drill, which simulated a coordinated attack at two locations 50 miles apart. The hams relayed hundreds of messages via voice nets and Winlink.

A New Model for Amateur Satellites

Washington photo)
AMSAT says the recently-launched HuskySat-1 satellite provides a new model for cooperation between the amateur satellite organization and educational institutions. According to the AMSAT News Service, this is the first instance of an AMSAT radio (a linear transponder in the ham bands) flying on a non-AMSAT satellite, the University of Washington's HuskySat-1. 

Under a split licensing arrangement with the FCC, HuskySat-1 will perform its scientific experiments under the supervision of the university and use a Part 5 experimental license to transmit its results back to Earth. When the experiments are completed later this year, UW will turn control of the satellite over to AMSAT, which will then activate the Part 97 amateur transponder. AMSAT says this opens the door for amateur radio payloads on future cubesat missions which (like this one) do not qualify for Part 97's so-called educational exemption. Details on HuskySat-1's mission are at <https://tinyurl.com/sehbfxy>.

AMSAT-South Africa Shifts Focus to Digital


South Africa's amateur satellite organization, AMSAT-SA, is shifting its cubesat development focus away from traditional analog transponders and toward digital SDR (software-defined radio) model. The group is currently working on two projects - the analog KLETSKous transponder which has already flown and performed well on a high-altitude balloon flight - and the SDR-based AfriCUBE. 

The South African Radio League reports that the AfriCUBE transponder development has reached a point at which it will soon be ready for field testing. The KLETSKous project is not being abandoned, says AMSAT-SA, but is being put on hold while a new lead developer is recruited, as the previous leader has had to step aside due to personal commitments.

Flocks of Woodpeckers?

(From IARU Region 1 Monitoring System website)
The International Amateur Radio Union's Region 1 Monitoring System is reporting that Russian over-the-horizon radar signals have been picked up on the 40, 30, 20 and 17-meter ham bands, along with Russian military communica- tions on 40, 30, 20 and 15 meters. 

The ARRL Letter reports that the radar signals are 12 kHz wide, making 40 sweeps per second and using FM on pulse. An additional over-the-horizon radar was reported in northern Iran, operating between 6.078 and 7.022 MHz, with 81 sweeps per second and AM on pulse over a 44-kHz bandwidth. 

(For those of you too young to remember it, the woodpecker reference in the title refers to early Russian OTH radar, back in the 1970s, which sounded like a woodpecker as it swept through the HF bands.)
