Hurricane Redux: Amateur Radio Community Fires Up for Maria
Caribbean Island residents and the Amateur Radio community hardly had
a chance to catch a breath from Hurricane Irma, as recovery operations
continue, before Hurricane Maria was knocking on the door. The
Hurricane Watch Net (HWN) activated September 18 on 14.325 MHz and on
7.268 MHz (after dark). The VoIP Hurricane Net activated the same day
to track Hurricane Maria and its potential impact in the Caribbean.
WX4NHC, the Amateur Radio Station at the National Hurricane Center,
activated to receive weather information from both nets, while the
Caribbean Emergency Weather Net (CEWN) was called up on September 18
on 3.815 MHz (and/or 7.188 and 7.182 MHz as propagation dictates) to
provide round-the-clock coverage during the passage of Hurricane Maria
and in the storm's immediate wake. It has been handling
health-and-welfare traffic in and out of Dominica and is accepting
inquiries via e-mail. (Indicate your name and location, as well as
that of the party sought).
The Federal Emergency Management Agency (FEMA) opened 60-meter
interoperability nets on September 19, using Channel 1, 5.330.5 MHz
(primary voice traffic) and Channel 2, 5.346.5 MHz (digital traffic).
These will remain active until the storm has passed and the need for
these nets no longer exists.
The Salvation Army Team Emergency Radio Network (SATERN) has been on
Delta II extended monitoring status on its 14.265 MHz frequency.
"Although the US Virgin Islands were heavily damaged, it was apparent
that they had some limited communications capabilities and other
resources," SATERN National Liaison Bill Feist, WB8BZH, said on
September 21. "Puerto Rican operators reported that there was an
island-wide power and communications blackout. It was reported that
Amateur Radio seemed to be the only communications that were
operational, and that was somewhat limited, as many 2-meter repeater
systems were still not operational."

Maxim Memorial Station W1AW at ARRL Headquarters resumed its normal
schedule of transmissions on Thursday morning, although the station
has not yet been reopened to visitors. W1AW will continue monitoring
active nets and 60-meter interoperability channels as needed. The
station was helping to support the communication response to Hurricane
Maria, monitoring the HWN, SATERN, the VoIP Hurricane Net, and the
Caribbean Emergency Weather Net (CEWN), as well as checking
Winlink2000 e-mail and providing interoperability support by keeping
various frequencies open for hurricane traffic. The station was
staffed around the clock during the communication emergency.
The Hurricane Watch Net, the VoIP Hurricane Net, and WX4NHC stood down
on September 20. The HWN was active for about 60 hours.

Irma news and information, as well as the ARRL news page.
Reports of Hurricane Devastation on Dominica Relayed by Amateur Radio
In the immediate aftermath of then-Category 5 Hurricane Maria's
passage over Dominica on Monday, Frans van Santbrink, J69DS, on St.
Lucia checked into the VoIP Hurricane Net to relay damage reports he'd
gathered via repeater conversations with other hams there. The New
York Times also reported and posted audio that Amateur Radio was a
primary source to gather initial damage reports from the storm-ravaged
Caribbean Island nation of some 70,000 residents. US-based Julian
Antoine, J73JA, solicited reports via a VoIP connection with the
J73MAN repeater on Dominica.
"All power lines are down, our telephone lines are down, internet
lines, everything is down," came a reply to Antoine's inquiry. "Roads
are blocked with debris. No confirmed information on fatalities or
injuries."
A subsequent responder reported, "Lots of flooding, water coming into
windows and doors," while another indicated that though he was "nice
and dry now," he had lost his roof and was at a shelter. "From what
I've seen so far, it's pretty bad," another report stated. The same
responder said he could see some landslides too, along with broken
trees and utility poles. "It's just damage all over," John Christian,
J73CC, said.
VoIP Hurricane Net Operations Director Rob Macedo, KD1CY, told ARRL
that he recorded the audio that The New York Times used on Tuesday
while he was monitoring the J62DX-L link on EchoLink.
In his report to the VoIP Hurricane Net, van Santbrink recounted a
damage account from Kerry Fevrier, J69YH, in Roseau, Dominica. "Trees
down, river has flooded half the village, cars are all over, most
houses have lost their roofs or are destroyed, the area between his
house and the church is just flattened...in his words, 'devastation is
total,'" van Santbrink told the net.
He also heard from J73CI, who lost his roof; J73WA on the northern end
of the island, who lost his tower and was uncertain how he was going
to weather the back end of the storm, and J73MH, who also lost his
roof and was "just hunkering down and hoping for the best."
Emergency Communications Director, IARU Region 2, Area E Noel Donawa,
9Y4X, reported on September 21 that the Office of Disaster Management
in Dominica's capital, Roseau, is now in operation using Amateur Radio
communication. "Only official traffic will be handled to assist in
getting government services functional," he said. "As soon as
personnel from the Regional Security System (RSS) search-and-rescue
damage assessment teams are deployed, health-and-welfare messages from
family and friends will be addressed.
As of Wednesday afternoon, the Caribbean Emergency Weather Network
(CEWN) continued to handle outbound health-and-welfare and other
necessary traffic from Dominica on 7.188 and 3.815 MHz. The net has
requested a clear frequency. No emergency operations center had been
established, airports remained closed, and damage assessment of the
seaports was under way, which would determine how soon relief supplies
and significant human resources can access the island. -- Thanks to

Amateur Radio Emergency Net Active in Wake of Earthquake in Central
Mexico
The FMRE National Emergency Net (Red Nacional de Emergencia or RNE)
activated Tuesday on 7.060 MHz following a magnitude 7.1 earthquake in
the central Mexico state of Puebla at 1814 UTC. The epicenter was some
75 miles southeast of Mexico City, which also felt the temblor and
suffered damage.
FMRE President Alfonso Tomez, XE2O, said participation from Mexican
radio amateurs has been excellent, and two mobile communication units
have been deployed, one south of Mexico City, where communication
problems have been reported, and the other in communities surrounding
the city, where communication problems exist. A FMRE representative
has been stationed in the emergency operations center in Mexico City
as well. Most of the traffic, Tomez said, has involved missing
persons.
The FMRE National Emergency Net also may use 3.690 MHz and 14.120 MHz
as well as IRLP reflector 9200 channel 08, and EchoLink.
Tomez said communication problems persist because of the heavy volume
of calls and message traffic over the cell telephone networks. Around
300 people have been killed and 30 buildings collapsed, he said. The
earthquake came 32 years to the day after a 1985 magnitude 8.0
earthquake struck Mexico City, killing some 9,500 people in and around
the capital city. Just one week ago, a magnitude 8.1 earthquake struck
off Mexico's southern coast, killing more than 60 people and causing
considerable damage.

Amateur Radio Supported Hurricane Irma Response in US Virgin Islands
Members of the St. Croix Amateur Radio Club supported the Hurricane
Irma response at the Virgin Islands Territorial Emergency Management
Agency (VITEMA), utilizing 60-meter band channel 2 (5.346.5 MHz USB)
to coordinate emergency communications. The club's NP2VI served as the
net control station at the St. Croix Emergency Operations Center
(EOC). Participants included the Virgin Islands National Guard Joint
Force Headquarters, National Guard Task Forces, and VITEMA EOCs on St.
Croix and St. Thomas. Puerto Rico Army MARS members also participated.
FEMA posted personnel on two Navy vessels, and they worked directly
with USVI amateurs via 60-meter interoperability channels.

Amateur Radio operators on St. Thomas, St. Croix, and St. John were
involved in the response. "Our local communications team is doing what
we are trained to do," USVI Section Manager Fred Kleber, K9VV, said.
"Our NIMS [National Incident Management System] training has paid off
in spades."
Ham radio volunteers were instrumental in passing critical
safety-of-life communications in the days immediately following
Hurricane Irma, accessing a 2-meter repeater from the VITEMA EOC.
Operators quickly disseminated important relief information (curfew
hours, points of distribution, weather bulletins, seaport status) and
served as the relay between the EOCs and emergency support functions,
and St. John Rescue and St. Croix using 2 meters.
Operators also have provided assistance in coordinating private and
military landings of supplies as well as medical evacuations at the
St. John Medical Center. The USVI now are dealing with the aftermath
of Hurricane Maria. -- Thanks to Garry Green, VITEMA; The ARRL Contest
Update
FCC Opens 630- and 2200-Meter Bands; Stations Must Notify UTC Before
Operating
The FCC has announced that the Office of Management and Budget has
approved, for 3 years, the information-collection requirement of the
Commission's March 29 Report and Order (R&O) that spelled out Amateur
Radio service rules for the two new bands -- 630 meters (472-479 kHz)
and 2200 meters (135.7-137.8 kHz). Notice of the action appeared in
the September 15 edition of the Federal Register. Before using either
band, stations must notify the Utilities Technology Council (UTC) that
they plan to do so. If UTC does not respond within 30 days, they may
commence operation.
On March 27, 2017, the FCC adopted the 2012 World Radiocommunication
Conference (WRC-12) implementation Report and Order (ET Docket 15-99),
amending its Amateur Radio rules to -- in the FCC's words -- "provide
for frequency-sharing requirements" in the two bands. Section
97.313(g)(2) of the new rules requires that, prior to starting
operation in either band, radio amateurs must notify UTC that they
intend to operate by submitting their call signs, the intended band(s)
of operation, and the coordinates of their antenna's fixed location.
The new rules do not permit any mobile operation.
"Amateur stations will be permitted to commence operations after a
30-day period, unless UTC notifies the station that its fixed location
is located within 1 kilometer of Power Line Carrier (PLC) systems
operating on the same or overlapping frequencies," the FCC said. PLC
systems are unlicensed. "This notification process will ensure that
amateur stations seeking to operate [on 630 or 2200 meters] are
located beyond a minimum separation distance from PLC transmission
lines, which will help ensure the compatibility and coexistence of
amateur and PLC operations, and promote shared use of the bands."
ARRL 630-Meter Experiment Coordinator Fritz Raab, W1FR, advised radio
amateurs who anticipate using either band to read the Federal Register
posting "to understand frequencies, power limitations, and operating
modes permitted." Experimental Group participant Ed Cole, KL7UW, has
been operating as WD2XSH/45 with 100 W into a 43 × 122-foot
base-loaded inverted L, achieving about 3 W ERP. In a message to the
Topband Reflector, Eric Tichansky, NO3M, noted that during his
operations as part of the ARRL Experimental Group and with his own FCC
Part 5 Experimental license, he enjoyed "many cross-country QSOs at
QRP power levels" using a 67-foot top-loaded vertical that shares the
radial field for his 160-meter antenna. The Antennas by N6LF website
offers more information.
HamSCI Presents Initial Eclipse Results at ARRL-TAPR Digital
Communications Conference
At the 36th annual ARRL and TAPR Digital Communications Conference
(DCC), held September 15-17 in St. Louis, members of the HamSCI group
presented preliminary evidence that the August 21 solar eclipse had a
significant effect on HF propagation. The DCC is geared toward
technically minded Amateur Radio operators who specialize in building
and designing hardware and software to support digital communication
and radio.
In their presentation, "HamSCI and the 2017 Total Solar Eclipse,"
HamSCI members Nathaniel Frissell, W2NAF; Bill Engelke, AB4EJ; Josh
Katz, KD2JAO; Spencer Gunning, K2AEM, and Josh Vega, WB2JSV, showed
initial results of the Solar Eclipse QSO Party (SEQP) and other HamSCI
eclipse experiments. Their presentation demonstrated that the number
of 14 MHz Reverse Beacon Network (RBN) spots decreased, while the
number of 1.8 MHz and 3.5 MHz spots increased during the eclipse
totality. The HamSCI researchers say this suggests a decrease in both
maximum usable frequency (MUF) and D-layer absorption during the
eclipse.
John Ackermann, N8UR, described his work in making wideband recordings
during the eclipse in his presentation, "How to Fill a Terabyte Disk:
Using Software Defined Radios in the HamSCI Solar Eclipse Experiment."

and NJIT students Josh Vega, WB2JSV; Spencer Gunning, K2AEM, and Josh
Katz, KD2JAO, with TAPR President Steve Bible, N7HPR, at the 36th
Annual ARRL and TAPR Digital Communications Conference in St. Louis.
In addition to the conference presentation, three New Jersey Institute
of Technology (NJIT) HamSCI papers were included in the conference
Proceedings. "HamSCI and the 2017 Total Solar Eclipse (Experiment
Description)," by Frissell et al., details the procedures for the
HamSCI eclipse experiments. "The H.A.R.C. Database and Visualization
Utilities," by Katz et al., describes a database for unifying RBN,
PSKReporter, WSPRNet, and other Amateur Radio propagation data in one
place for research purposes. Vega's "Developing a Solar Eclipse
Simulation for Greater Good" describes how to simulate the SEQP using
the PHaRLAP raytracing toolkit and SAMI3 model of the eclipsed
ionosphere.
HamSCI team members announced that the HamSCI Workshop will be held at
NJIT in Newark on February 23-24.
IARU ministrative Council Considers New Radio Spectrum Pollution
Threat
The ministrative Council (AC) of the International Amateur Radio Union
(IARU) believes high-power wireless power transfer (WPT) for electric
vehicles has significant potential to interfere with radio
communication. That assessment came as the AC met on September 15 and
16 in Landshut, Germany, immediately prior to the IARU Region 1
Conference, to review its priorities and positions with regard to the
2019 World Radiocommunication Conference (WRC-19). Conference Agenda
Item 9.1.6 would call for studies in advance of WRC-23 to assess the
impact of WPT for electric vehicles on radiocommunication services and
to study suitable harmonized frequency ranges to minimize its impact.
The AC determined that addressing the threat requires an increased
commitment of resources by potentially affected radiocommunication
services, including Amateur Radio.
The WPT issue came up earlier this month at the meeting of CEPT WRC
Project Team D, held in Vilnius, Lithuania, the week of September 11.
At that gathering, IARU addressed the impact of spurious emissions
from proposed high-power WPT systems for electric vehicles.
As the ITU explained in its August 2016 report, "Applications of
wireless power transmission via radio frequency beam," WPT technology
is considered a game-changer. "We will be able to become free from
lacking electric power when electric power will be supplied
wirelessly," the report said. WPT vehicle applications typically use
frequencies in the LF and MF range.
In addition to WPT, the WRC-19 agenda includes several other items of
potential concern to radio amateurs and a possible allocation in
Region 1 of 50-54 MHz to the Amateur Service to harmonize with the
allocations in the other two International Telecommunication Union
(ITU) regions.
Delegates reviewed and updated the strategic plan to develop support
for amateur spectrum allocations in 2016-2020, and they approved
action plan for the remainder of 2017 and 2018. They also reviewed and
adopted the IARU 2018-2020 budget, based upon anticipated financial
contributions from the IARU International Secretariat and the three
regional organizations. The budget adopted reflects ongoing efforts to
minimize expenses.
Regional representatives on the AC reported progress in their areas,
including the successful Amateur Radio ministration Course, a course
attended by administrators from several Latin American countries that
was offered earlier this year in Mexico City.
Tore Worren, LA9QL, was appointed as EMC Coordinator, replacing Thilo
Kootz, DL9KCE, who has had to step down because of a change in
employment. Read more.
JOTA 2017 Organizers Urge Scout Stations to Register Now
Scouting's Jamboree on the Air/Jamboree on the Internet (JOTA/JOTI)
event takes place over the October 20-22 weekend, and organizers are
urging Scout stations planning to participate to register now. The
world JOTA-JOTI team has activated its online sign-up system.
"Our number one message at this time is to register their station and
get ready for JOTA," JOTA Coordinator Jim Wilson, K5ND, told ARRL.
"It's time for Scout groups to bring together their open action items
-- ordering patches, printing handouts, gathering equipment, reminding
staff members, verifying location, and getting the word out to the
Scouts to be prepared for a fabulous experience talking with other
Scouts across the country and hopefully around the world."
JOTA is the world's largest Scouting event, held annually over the
third full weekend in October, and Scouts of any age can participate
-- from Cub Scouts to Boy Scouts and Venturers, male and female.
During JOTA, Amateur Radio links Scouts with other Scouts and hams,
locally and worldwide. Since the first JOTA in 1958, millions of
Scouts have met each other through this event to exchange ideas and
share experiences via ham radio. Many contacts made during JOTA have
resulted in enduring friendships and connections.
According to the World Scout Bureau, the 2016 JOTA had nearly 1.3
million Scout participants from more than 30,000 locations, and
reached 156 countries.
The World JOTA-JOTI team has published a Participant's Guide to help
Scouts to get on the air and the internet for the largest Scouting
event in the world. They've also published a brief history of the 60
years of Jamboree on the Air as well as the Top 10 Challenges and
Activities in 2016 that might provide ideas for your event this year.
An online scheduling tool is available too.
For participating via EchoLink, two conference nodes now have been
designated for Scout contacts -- *JOTA-365* (node 480809) and *JAMBO*
(node 832996). Visit the K2BSA Radio Scouting page for more
information on frequencies, including D-STAR, DMR, and IRLP.
Former MIT President, Electrical Engineering Professor Paul E. Gray,
ex-W2UWN, SK
Former Massachusetts Institute of Technology (MIT) President Paul E.
Gray, ex-W2UWN and K1ZVT, of Concord, Massachusetts, died on September
18. He was 85. Gray had a nearly lifelong association with MIT,
including turns as student, professor, dean of engineering, associate
provost, chancellor, president, and MIT Corporation chair. He served
as MIT's 14th president for the decade 1980 to1990, and chaired the
MIT Corporation for another 7 years before returning to teaching and
advising. He was an emeritus professor of electrical engineering.
"Gray transformed the Institute through his commitment to enhancing
undergraduate education and increasing the presence of women and
underrepresented minorities on campus," an MIT obituary said. "With
his wife, Priscilla King Gray, at his side, he helped guide MIT
through the social change and technological transformation that marked
the second half of the 20th century."
Gray's administration is credited with expanding MIT's industrial
relations and developing major research in the areas of
communications, health sciences and technology, microelectronics, and
brain and cognitive science.
Gray became a radio amateur as a young teen in the 1940s, first as
W2UWN in his native New Jersey, and later as K1ZVT. He let his Amateur
Radio license lapse in 1970.
"I can remember as early as first and second grade making things
electrical, like electromagnets," Gray recounted during an MIT
Infinite History interview. "Winding copper wire on a nail and being
able to turn it on and off. And that just continued through as far
back as I can remember. I was involved in making gadgets around the
house. If anything could be taken apart that was electric, from clocks
to radios or whatever. By the time I was 10, I was doing radio repair
for the neighbors, vacuum tube radios at that point, of course. As
soon as the war ended, I got myself licensed as an Amateur Radio
operator and built all my equipment."
Gray said he was influenced by his utility technician father's
curiosity about, and experiments with, electricity that led him into
his own interest in radio, starting with a crystal radio and later a
regenerative receiver built during World War II when Amateur Radio was
suspended for the duration. Gray said he entered high school "with the
conviction I was going to study electrical engineering."
According to MIT, Gray, as a professor, was part of a 1960s effort "to
overhaul the way electrical engineering was taught, moving the focus
away from vacuum tubes and squarely onto semiconductor electronics."
Working with colleagues at MIT, Stanford, UC Berkeley, Raytheon, and
IBM, he wrote seven textbooks and other materials. Gray was a life
fellow of the Institute of Electrical and Electronics Engineers, and a
member of the National Academy of Engineering.
Gifts in Gray's memory may be made to MIT's Aging Brain Initiative to
support research on Alzheimer's disease. Read more. -- Thanks to MIT;

In Brief...
Hurricane Damage Forces Changes to Planned DX Operations: Members of
Argentina's Yaguarete DX Group, expected to be active as PJ7T from
Sint Maarten from October 24 through November 4, have cancelled their
plans due to Hurricane Irma damage. "Hurricane Irma destroyed 95% of
infrastructure on the island, and it will be impossible to arrive and
live there for a long time," the group said in its announcement. It
has changed the destination for its fall DXpedition to San Andres
Island and is in the process of working out the formalities.
Meanwhile, the PJ7TM station of Tom Metz, K2GSJ, is said to have been
"wiped out," and Metz is heading there in October to repair the
damage. Post-Hurricane Irma drone and ground video in Sint Maarten is
available on YouTube. W3HNK and K3NK also have dropped plans to
operate from Guadeloupe and Sint Maarten from October 23 until
November 1, including the CQ World Wide DX SSB Contest. The Polish
team's mid-November TO2SP DXpedition to St. Barthelemy Island is still
a go, however, "barring any further surprises," a team spokesperson
said. -- Thanks to The Daily DX for some information

The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports:Over the past week, solar indices
declined. Lower activity persists, and the uptick in solar activity on
September 2-10, when sunspot numbers were 71, 96, 122, 122, 79, 94,
89, 49, and 38 and solar flux was 100, 120, 140, 121, 133, 129, 117,

solar minimum, perhaps in 2021 or 2022.
But perhaps we will be surprised again.
Average daily sunspot numbers declined over the past few weeks from
87.3 to 45 and 13.6, and average daily solar flux from 114.1 to 97.6
and 72.6.
Average daily planetary A index was 18, 27.3, and 21.1, while average
mid-latitude A index (measured in Virginia, at a magnetometer on
Wallops Island) was 16.7, 18.3, and 17.1.
Predicted solar flux is 74, 73, 80, and 85 on September 21-25; 90 on
September 26-27; 105 on September 28; 115 on September 29-October 6;
