"Quantum Radio" May Offer New Twist on Communicating in Problematic
Environments
Researchers at the National Institute of Standards and Technology
(NIST) have demonstrated that quantum physics might enable
communication and mapping in locations where GPS, cell phones, and
radio are not reliable or don't work at all, such as indoors, in urban
canyons, underwater, and underground. NIST announced the technology
advance on January 2. The technology may have marine, military, and
surveying applications. The NIST team is experimenting with
very-low-frequency (VLF) digitally modulated magnetic signals, which
propagate farther through buildings, water, and soil than conventional
electromagnetic signals at higher frequencies.
"The big issues with very-low-frequency communications, including
magnetic radio, are poor receiver sensitivity and extremely limited
bandwidth of existing transmitters and receivers. This means the data
rate is zilch," said NIST project leader Dave Howe, AD0MR.
"The best magnetic field sensitivity is obtained using quantum
sensors. The increased sensitivity leads in principle to better range.
The quantum approach also offers the possibility to get high-bandwidth
communications like a cellphone has. We need bandwidth to communicate
with audio underwater and in other forbidding environments," he said.
NIST researchers have demonstrated detection of digitally modulated
magnetic signals by a magnetic-field sensor that relies on the quantum
properties of rubidium atoms. The NIST technique varies magnetic
fields to modulate or control the frequency -- specifically, the
horizontal and vertical positions of the signal's waveform -- produced
by the atoms.
Physicist Dave Howe, AD0MR, aligns a laser beam to pass through a tiny
glass cell of rubidium atoms inside the cylindrical magnetic shield.

receiver for digitally modulated magnetic VLF signals. [NIST photo]
NIST developed a direct current magnetometer that uses polarized light
as a detector to measure the "spin" of rubidium atoms in a tiny glass
cell induced by magnetic fields. Changes in the atoms' spin rate
correspond to an oscillation in the dc magnetic fields, creating
alternating current voltages at the light detector that are more
useful for communications.
"Atoms offer very fast response plus very high sensitivity," Howe
said. "Classical communications involves a tradeoff between bandwidth
and sensitivity. We can now get both with quantum sensors," Howe
speculated on an Amateur Radio application.
"The quantum radio is great fun, far better sensitivity than any other
receiver, at room temperature, anyway," Howe told ARRL. "The atoms in
the gas cell replace the 'antenna' and detection in the classical
sense. It would be nice to try modulation in the 2200-meter band using
the quantum receiver for detection." In the future, the NIST team
plans to develop improved transmitters.
In the NIST tests, the sensor detected digitally modulated magnetic
field signals with strengths of 1 picotesla -- one millionth of
Earth's magnetic field strength -- and at frequencies below 1 kHz.
The researchers hope to extend the range of low-frequency magnetic
field signals by boosting the sensor sensitivity, suppressing noise
more effectively, and increasing and efficiently using the sensor's
bandwidth.
The NIST strategy requires inventing an entirely new field, which
combines quantum physics and low-frequency magnetic radio, said Howe,
who told ARRL that ham radio enhanced his interest in communications
when he was in ninth grade in New Mexico. "So, it's what guided my
interest into applied quantum physics in college. Ham radio was the
bigger influence in all ways." Howe retired from NIST last September.
He now is a research advisor for NIST and Colorado University.
Fox-1D Satellite Set to Launch this Week, China to Launch Five New
CubeSats
The launch from India of AMSAT-NA's Fox-1D CubeSat will take place on
January 12 (UTC). The Polar Satellite Launch Vehicle (PSLV) flight had
to be rescheduled from December 30. AMSAT Vice President Engineering
Jerry Buxton, N0JY, delivered Fox-1D to Spaceflight Inc. in Seattle
last November for integration.
In addition to a Fox-1 U/V FM transponder, Fox-1D will carry several
university experiments, including a MEMS gyro from Pennsylvania State
University-Erie, a camera from Virginia Tech, and the University of
Iowa's High Energy Radiation CubeSat Instrument (HERCI) radiation
mapping experiment. Fox-1D also carries the AMSAT "L-Band
Downshifter," which gives the option of utilizing a 1.2 GHz uplink for
the FM transponder. The Fox-1D downlink will be on 145.880 MHz, and
uplinks will be on 435.350 and 1267.350 MHz (67 Hz CTCSS), switchable.
The PSLV also will carry the French PicSat, which carries an Amateur
Radio V/U FM transponder. PicSat will perform space observations. The
transponder uplink is 145.910 MHz, the downlink is 435.525 MHz. Some
30 smaller secondary payloads from India, the US, and other
international entities will also be on the launch, AMSAT News Service
has reported.
AMSAT will release Fox-1D's Keplerian elements on its website as soon
as they are known and seeks telemetry data on the CubeSat to assist
with commissioning. "Participation in telemetry collection by as many
stations in as many parts of the world as possible is essential as
AMSAT Engineering looks for successful startup and indications of the
general health and function of the satellite as it begins to acclimate
to space," AMSAT said over the weekend. AMSAT said the on-orbit
checkout procedure could be completed in a few days. AMSAT asks the
Amateur Satellite community to refrain from using the transponder
uplink while on-orbit testing is under way.
Chinese CubeSats Set to Launch
Meanwhile, AMSAT-UK reports that China will launch Hunan Amateur Radio
Society's constellation of five similar 6U CubeSat spacecraft on
January 17 from its Jiuquan Space Center. Identified as TY-2 through
TY-6, the satellites will carry out ionospheric transmission-detection
experiments, in addition to Amateur Radio HF/VHF/UHF re-transmitting
experiments in any narrow-band mode. The constellation will also carry
out inter-satellite communication experiments that include Amateur
Radio loads, Li-Fi high-speed LED digital downlink, and CW lamp signal
communication experiments. Downlinks are on 70 centimeters using 9.6
kbps GMSK and on 2.4 GHz and 5.8 GHz using 5 Mbps OFDM.

Thomas Fire Response Also Demonstrates Amateur Radio's Social Media
Value
Santa Barbara Amateur Radio Club (SBARC) members kept a close watch on
the Thomas Fire after it broke out in early December. Using a variety
of the club's analog and digital Amateur Radio assets, radio operators
were able to observe fire-fighting efforts first hand and pass along
immediate information, often before it was reported by official
sources or by local news media. SBARC operates five communication
sites in Santa Barbara County, including sites on Diablo Peak on the
mostly uninhabited Santa Cruz Island, and on Santa Ynez Peak.
"These two sites host [Automatic Dependent Surveillance-Broadcast]
ADS-B receivers that are connected via a combination of amateur
microwave IP links and mesh networking and were used to track and
monitor airborne firefighting activities," Levi Maaia, K6LCM, co-chair
of SBARC's Telecommunications Services Committee, told ARRL.
Starting in mid-December, a round-the-clock emergency net convened on
2 meters, as commercial power for much of Santa Barbara County was cut
and the fire descended on residential communities in Santa Barbara
County, prompting multiple evacuation orders. With repeaters on
generator power and many operators running on battery power, net
traffic consisted of official information, including evacuation
orders, live reports on the rapidly approaching fire line from
operators who remained inside the mandatory evacuation area, related
traffic about firefighting efforts, and wind and weather conditions.
SBARC volunteers set up an ad hoc remote receiving station to stream
live fire ground and air communications audio over the internet and
mesh network.

Radio TV camera on December 4.
As fire crews came off duty, one firefighter and Amateur Radio
operator joined the net to offer a firsthand account of operations
from an insider's perspective. SBARC members also assisted visiting
fire crew members with mobile radio antenna repairs in the field.
Maaia said social media proved to be a valuable communication asset,
as most official organizations, such as incident command and emergency
management agencies, were disseminating official information via
Twitter immediately upon release. "Amateur stations without power,
cell phone or internet access could be kept informed of important
information including evacuation orders, via the Amateur Radio net,"
Maaia explained. "SBARC also served as an aggregator for Thomas
Fire-related information by featuring tweets on the club website."

The largest in modern California history, the Thomas Fire caused
devastating losses in Ventura and Santa Barbara counties. "Although
the Santa Barbara ARES group never activated, Amateur Radio proved to
be a valuable mode of communication, especially when coupled with
social media, amateur mesh networking, IRC chat (over mesh and
internet) and live audio streaming," Maaia said.
In Ventura County, the Thomas Fire damaged or destroyed some Amateur
Radio resources normally available to provide emergency communication.
It was an Amateur Radio TV camera that caught the first images of the
Thomas Fire on December 4. A fundraising effort now is under way to
help a repeater system operator to replace gear and to bolster the
rest of the system for future such emergencies. Fundraising sparkplug
Ben Kuo, AI6YR, said the fire demonstrated the difficulty of keeping
equipment running in remote locations during fire emergencies.

"We also discovered other sites faced serious limitations after
utility power was cut and solar panels were obscured by vast clouds of
smoke," Kuo recounted in his solicitation. "This GoFundMe [campaign]
will go toward enhancing the existing ham radio repeater network, to
make it more reliable in emergencies." High-quality video cameras for
those repeater sites is another possibility.
During the Thomas Fire, Kuo helped bridge the divide between Amateur
Radio and social media, and even firefighters would check his feed to
see what was going on in other areas of the fire, he said. "It's a
very powerful combination," Kuo told VC Star. An ARRL member, Kuo, of
Newbury Park, founded the socaltech news site. He's been licensed for
3 years and serves as an ARRL Technical Specialist for the ARRL Santa
Barbara Section.
Radio Amateurs Track Major East Coast Winter Storm
WX1BOX, the Amateur Radio Station at the National Weather Service
(NWS) office in Taunton, Massachusetts, joined numerous SKYWARN nets
across New England in activating for an early-January nor'easter that
brought significant coastal flooding, damaging winds -- with
hurricane-force wind gusts downing trees and power lines -- and heavy
snow accumulations to the region. The eastern coast of New England
experienced high snowfall rates, whiteout conditions, and even
"thunder snow." A dramatic drop in barometric pressure generated a
so-called "bomb cyclone."

Coordinator and NWS Taunton SKYWARN liaison at WX1BOX. [Ben Sipprell

WX1BOX was active for 16.5 hours, supporting data gathering for the
NWS. Local and state emergency managers, broadcast media, and other
agencies also used these reports for situational awareness during the
storm and to assess the need for any later recovery efforts.
"A widespread 8 to 18 inches of snow fell across southern New England
away from Cape Cod and the Islands. There were reports of
thunderstorms with snowfall rates in the 2 to 3 inches per hour
range," said Rob Macedo, KD1CY, Eastern Massachusetts Assistant
Section Emergency Coordinator and NWS Taunton SKYWARN liaison. "Wind
gusts between 70 and 76 MPH were recorded over Cape Cod and the
Islands, and wind gusts in the 40-70 MPH range were common across the
rest of southern New England."
Macedo said the severe and widespread coastal flooding in some eastern
Massachusetts locations was at the higher end of coastal flood events
experienced in the last 10 years or so.
WX1BOX posted a report, with details on snowfall amounts, winds,
coastal flooding, wind damage, and photos and videos from the storm on
its Facebook page.
Cape Cod Amateur Radio Emergency Service (ARES) was active at the
Barnstable County Mutual Aid Coordination Center (MACC), convening
ARES/SKYWARN nets and providing wind damage and coastal flood reports
from their region. For the most part, Cape Cod and the Islands
received rain, which was followed by a period of snow as temperatures
dropped. The resulting "flash freeze" conditions led to dangerously
icy roadways. Damaging winds causing scattered power outages and
coastal flooding were the biggest problems, with an inch or two of
rainfall in the area. Staffing the station was Cape Cod ARES District
Emergency Coordinator Frank O'Laughlin, WQ1O, and Tom Wruk, KB1QCQ.
The Peabody Emergency Operations Center (EOC) was active on the
Massachusetts North Shore, and the EOC served as a net control point
for SKYWARN nets in the North Shore area. Coastal flooding reports
from the North Shore and surrounding areas and snowfall totals were
relayed to WX1BOX and other agencies from their nets. Staffing the EOC
station were North Shore ARES DEC Jim Palmer, KB1KQW; Matt Knowles,
KC1AEI, and Dave Pais, N1VSI.

At the Eastern Massachusetts ARES section level, ARES went on standby
for any agency needs or to support any local ARES activations by
Eastern Massachusetts ARES SEC Marek Kozubal, KB1NCG. Local nets were
active on approximately 10 different repeaters across the NWS Taunton
coverage area. The New England Echolink/IRLP reflector system was also
active, with reporting stations from across New England, supplemented
by a tie-in to the conference node typically used by the VoIP
Hurricane Net.
An offer of assistance came from members of Illinois SKYWARN,
including a team member who handles SKYWARN for WX9LOT, the Amateur
Radio station at the NWS Chicago/Romeoville office. Debby Gray,
WX9VOR, and Joe Perry, K9JPP, assisted by monitoring Echolink and
supported data entry of snowfall reports from the region.
"This demonstrated a 'virtual EOC' approach to storm monitoring
utilizing out-of-area resources to support a storm incident with local
personnel providing local perspective," Macedo said.
Operators at WX1GYX, the Amateur Radio station at the Gray, Maine, NWS
Office, were active all day on January 4, gathering reports from
various sources via 2-meter FM, DMR, and HF. Tim Watson, KB1HNZ, and
Eric Emery, KC1HJK, handled net control duties, with support from
Waylon McDonald, KC1HJN, and members of Mt. Washington Valley ARES. --

DXpedition Leader, Contester, Mentor David Collingham, K3LP, SK
Well-known DXpedition leader and contester David Collingham, K3LP, of
Mt. Airy, Maryland, died on January 6 after falling through the ice on
a pond near his home the previous evening while trying to rescue his
stranded dog. An ARRL member, he was 59. Collingham was co-leader,
with Paul Ewing, N6PSE, of the 2016 VP8STI/VP8SGI DXpedition to South
Sandwich and South Georgia Islands, and he was president of the
Intrepid-DX Group.
According to news accounts, Collingham had alerted his family that his
golden retriever had fallen through the ice, but by the time they and
rescuers arrived on the scene, Collingham had already slipped beneath
the ice.
Licensed at age 15 as WN6KTF in his home state of California,
Collingham went on to take part in more than 70 DXpeditions and served
as leader or co-leader of 14 major DXpeditions. He was a 2014 inductee
to the CQ DX Hall of Fame, credited with focusing on using Amateur
Radio as an educational tool at home and abroad. With the support of
Collingham's long-distance coaching, teacher Bev Matheson, KJ6RSX, a
Fontana, California, elementary school teacher, was encouraged to
start a ham radio club for fourth and fifth graders at Dorothy Grant
Elementary School. A Fontana High School graduate, Collingham provided
a complete station for the school. He also promoted and taught Amateur
Radio abroad.
Professionally, Collingham was president and CEO of International
Quality Registrars Corporation, a global ISO 9001 certification firm.
NCJ Editor Scott Wright, K0MD, recalled hearing Collingham speak at a
Dayton DX Dinner. "He challenged those in attendance to always think
of others, especially DXers who are generally less fortunate," Wright
recounted. Collingham also challenged those in attendance to help
school clubs and start one, and to realize that ham radio would die,
were a new generation not mentored and fostered, Wright said.
"David lived his life bold, courageous, and heroically, and he died
trying to save his beloved dog," Ewing wrote in announcing
Collingham's death. "He will always be a hero in our hearts."

Registration for the 69th annual International DX Convention opens on
January 15. The convention takes place April 20-22 at the Visalia
Convention Center. The Southern California DX Club (SCDXC) sponsors
the 2018 event. Online convention registration opens on January 15 at
1700 UTC. The Saturday banquet program will be on the 3Y0Z DXpedition
to Bouvet Island. Convention co-chairs are Cathy Gardenias, K6VC, and
Kris Jacob, KC6TOD. E-mail for more information. The convention is
calling for DX and technical presentations. If interested, contact
Bill Kendrick, N6RV, with a brief description.
Denny Berg, WB9MSM, of Watertown, Wisconsin, has achieved his goal of
completing DXCC using the new FT8 digital mode. It took him just 4
months. "I can tell all of you that this mode is spreading like
wildfire throughout all the HF bands," Berg told The Daily DX. "I have
also noticed that most of these FT8ers use Logbook of The World (LoTW)
for their confirmation process." Berg, an ARRL member, said his
current DXCC count stands at 104 entities, all confirmed via LoTW. He
said he was able to work all states on FT8 in about 6 weeks of
operating. A radio amateur since 1970, Berg was among the stations
activating W1AW/9 from Wisconsin during the ARRL Centennial in 2014.
