World Amateur Radio Day 2019 Marks International Amateur Radio Union
Founding
Thursday, April 18, is World Amateur Radio Day (WARD), this year marking the
94th anniversary of the International Amateur Radio Union (IARU), which was
founded in Paris in 1925. Each year, WARD celebrates Amateur Radio's
contribution to society. Groups in the US and around the world will
celebrate WARD 2019 with on-air activities.
"I am pleased to extend my greetings for World Amateur Radio Day," IARU
President Tim Ellam, VE6SH, said. April 18 is the day for all of Amateur
Radio to celebrate and tell the world about the science we can help to
teach, the community service we can provide, and the fun we have. I would
encourage all radio amateurs to join in the celebrations and promote Amateur
Radio on the air or in your community."
Amateur Radio experimenters were the first to discover that the shortwave
spectrum was not the wasteland experts of the time considered it to be, but
a resource that could support worldwide propagation. In the rush to use
these shorter wavelengths, Amateur Radio was "in grave danger of being
pushed aside," the IARU's history notes. Amateur Radio pioneers met in Paris
in 1925 and created the IARU to support Amateur Radio around the globe.
Two years later, at the International Radiotelegraph Conference, Amateur
Radio gained allocations still recognized today -- 160, 80, 40, 20, and 10
meters. More bands have followed, and the IARU has been working to defend
and expand Amateur Radio frequency allocations ever since.
From the 25 countries that formed the IARU in 1925, the IARU has grown to
include 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.
The International Telecommunication Union (ITU) has recognized the IARU as
representing the interests of Amateur Radio.
Groups are encouraged to promote their WARD activity on social media by
using the hashtag #WorldAmateurRadioDay on Twitter, Instagram, and Facebook.
Visit the IARU World Amateur Radio Day web page for a listing of on-the-air
activities.

Solar Cycle 25 Predicted to be Similar to Cycle 24
Scientists predicting the sun's activity for Solar Cycle 25 say it's likely
to be much like that of current Cycle 24, which is declining and predicted
to bottom out in 2019 or 2020. Solar Cycle 25 Prediction Panel experts said
Solar Cycle 25 may get off to a slow start, but is anticipated to peak
between 2023 and 2026 with a sunspot range of 95 to 130. This is well below
the typical average of 140 to 220 sunspots per solar cycle. The panel
expressed high confidence that the coming cycle should break the trend of
weakening solar activity seen over the past four cycles. The Solar Cycle
Prediction Panel forecasts the

number of sunspots expected for solar maximum, along with the timing of the
peak and minimum solar activity levels for the cycle. The outlook was
presented on April 5 at the 2019 NOAA Space Weather Workshop in Boulder,
Colorado.
"We expect Solar Cycle 25 will be very similar to cycle 24: Another fairly
weak cycle, preceded by a long, deep minimum," said panel co-chair Lisa
Upton, a solar physicist with Space Systems Research Corp. "The expectation
that Cycle 25 will be comparable in size to Cycle 24 means that the steady
decline in solar cycle amplitude, seen from cycles 21 - 24, has come to an
end and that there is no indication that we are currently approaching a
Maunder-type minimum in solar activity."
The solar cycle prediction gives a rough idea of the frequency of space
weather storms of all types, from radio blackouts to geomagnetic storms and
solar radiation storms. In addition to its effects on Amateur Radio signal
propagation, space weather can affect power grids; critical military,
airline, and shipping communications; satellites and GPS signals, and can
even threaten astronauts through exposure to harmful radiation.
Solar Cycle 24 reached its maximum in April 2014, with a peak average of 82
sunspots. The sun's northern hemisphere led the sunspot cycle, peaking more
than 2 years ahead of the southern hemisphere sunspot peak. Given that the
sun takes 11 years to complete one solar cycle, this is only the fourth time
that US scientists have issued a solar cycle prediction. The first panel
convened in 1989 for cycle 22.
For Solar Cycle 25, the panel hopes for the first time to predict the
presence, amplitude, and timing of any differences between the northern and
southern hemispheres on the sun, known as hemispheric asymmetry. Later this
year, the panel will release an official sunspot number curve showing the
predicted number of sunspots during any given year and any expected
asymmetry. The panel will also look into the possibility of providing a
solar flare probability forecast.
"While we are not predicting a particularly active Solar Cycle 25, violent
eruptions from the sun can occur at any time," said Doug Biesecker, panel
co-chair and a solar physicist at NOAA's Space Weather Prediction Center
(SWPC).

MIT Requests FCC Rules Waiver for Medical Monitoring Device
The Massachusetts Institute of Technology (MIT) is seeking a waiver of some
Part 15 rules in order to obtain FCC certification of its WiTrack System, a
swept-frequency ultra-wide band (UWB) indoor medical monitoring device.
According to MIT, the WiTrack System uses an indoor swept signal of up to
2.5 GHz in the 6 - 8.5 GHz band to passively monitor mobility, breathing,
and other physiological signals in patients and senior adults. Because the
system would transmit an RF signal and receive its reflection from the
environment, it would not require the use of body-worn sensors. MIT has
indicated that different versions of the devices would sweep slightly
different frequencies within the 6 - 8.5 GHz range.
According to MIT publicity material, WiTrack tracks the 3D motion of a user
from the radio signals reflected off a person's body. It works even if the
person is occluded from the WiTrack device or in a different room. WiTrack
does not require the user to carry any wireless device.
"WiTrack localizes the center of a human body to within 10 to 13 centimeters
in the x and y dimensions (about the size of an adult hand), and 21
centimeters in the z dimension. It also provides coarse tracking of body
parts, identifying the direction of a pointing hand with a median of 11.2
degrees. It can also detect falls with 96.9% accuracy. WiTrack can be
incorporated into consumer electronics and has a wide set of applications,"
MIT says.
Section 15.503(d) of the FCC's rules defines a UWB transmitter as an
intentional radiator that, at any point in time, has a fractional bandwidth
equal to or greater than 0.20 or has a UWB bandwidth equal to or greater
than 500 MHz, regardless of the fractional bandwidth. The WiTrack System
would not satisfy this definition, because each frequency step is less than
500 MHz in bandwidth "at any point in time," MIT says, even though the total
bandwidth needed for optimal performance exceeds 500 MHz. MIT states that
the waiver it seeks is similar to those previously granted by the
Commission, and that grant of a waiver for the WiTrack System would be in
the public interest.
The waiver request has been folded into ET Docket 19-89, and interested
parties have until April 18 to comment and until May 3 to file reply
comments.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: The first 3 days of the reporting week

70 on May 17 - 19; 69, 68, 69, and 69 on May 20 - 23, and 70 on May 24 - 25.
The predicted planetary A index is 14, 12, and 8 on April 11 - 13; 5 on
April 14 - 23; 10, 8, 5, 10, 8, and 5 on April 24 - 29; 10 on April 30 - May
2; 7 on May 3; 5 on May 4 - 20, and 10, 8, 5, 10, and 8 on May 21 - 25.
Sunspot group 2738 appeared on April 7. It's the bright spot on this STEREO
spacecraft image. This view will move from left to right over time, until it
disappears off the right side.
Sunspot numbers for April 4 - 10 were 0, 0, 0, 11, 12, 12, and 13, with a
mean of 6.9. The 10.7-centimeter flux was 70.3, 71.7, 73.6, 76.5, 78.6, 79,
and 78.1, with a mean of 75.4. Estimated planetary A indices were 10, 14, 7,
5, 13, 11, and 14, with a mean of 10.6. Middle latitude A index was 8, 10,
7, 5, 12, 11, and 10, with a mean of 9.

AMSAT, ARRL Comment in FCC Orbital Debris Mitigation Proceeding
AMSAT has told the FCC that several proposed rule changes related to the
mitigation of orbital debris would have an extremely detrimental effect on
both the Amateur Satellite Service and AMSAT's ability to launch and operate
new satellites, including AMSAT's upcoming GOLF satellites. AMSAT filed
comments on April 5 on an FCC Notice of Proposed Rule Making in IB Docket
18-313. AMSAT argues that amateur satellites often have longer mission
lifespans than other small satellites and that the FCC should take a mission
duration of 5 to 10 years into account when determining whether or not an
amateur satellite will meet the orbital debris regulations, either by
transferring to a parking orbit or re-entering the atmosphere within 25
years of mission completion. Current practice is to assume a "zero-year"
mission and to require that amateur satellites meet the debris regulations.
AMSAT also urged the Commission to consider alternatives to a proposed rule
that would restrict to altitudes of 650 kilometers or less satellites in
low-Earth orbit that plan to meet the orbital debris mitigation guidelines
through atmospheric re-entry. AMSAT noted that, had this rule been in place,
it would not have been permissible to deploy AO-85 and AO-91 in their
current elliptical orbits with apogees of approximately 800 kilometers, even
though both will re-enter within 25 years due to their low perigees.
ditionally, AMSAT noted that current plans for the GOLF-1 satellite are to
meet orbital debris mitigation guidelines through atmospheric re-entry by
deploying a drag device that will ensure re-entry within 25 years, despite
deployment at an altitude higher than 1,000 kilometers. This proposed rule
would prohibit GOLF-1's deployment at that altitude.
The Commission's proposed rules would further require that Amateur Satellite
licensees indemnify the government against any claims made against the US
due to the operation of a satellite. AMSAT believes this proposal would end
the ability of AMSAT, or any other entity in the US, to launch and operate
amateur satellites and urged the FCC to consider alternatives.
In separate comments, ARRL said it supports "reasonable efforts to mitigate
orbital debris" but that the FCC "must tailor its regulations for the
Amateur Satellite service" and "not inadvertently impair the service's
continuing vitality by applying rules crafted for commercial satellite
services."
In this regard, ARRL supports AMSAT's positions, which suggest that "the
nature of the modifications needed [should] achieve the Commission's
expressed regulatory objectives without needlessly impairing the Amateur
Satellite service."
ARRL said the FCC should exempt amateur satellites or otherwise ameliorate
its proposed indemnification requirement and said that only telemetry "used
to command onboard propulsion systems" should be subject to encryption.
ARRL also said amateur satellites proposed for disposal by atmospheric
re-entry should not be restricted to orbital altitudes of 650 kilometers or
lower, and that the longer duration of amateur satellite missions should be
factored into the time required for a satellite to naturally de-orbit or be
transferred to "a parking orbit."
Interested parties may file reply comments by May 5 via the FCC Electronic
Comment Filing Service (ECFS). Read more. -- Thanks to AMSAT News Service

Florida ARES, State of Florida Considering Memorandum of Understanding
Amateur Radio Emergency Services (ARES®) Section Emergency Coordinators
(SEC) from the ARRL Northern, West Central, and Southern Florida sections
met recently with state Emergency Management Communication leaders to
discuss improved integration of Amateur Radio during emergencies. A draft
Memorandum of Understanding (MOU) between ARES and the State of Florida was
presented for further consideration.
From left to right: Florida Telecommunications Specialist III Bob Little,
N4RGL; West Central Florida Section Emergency Coordinator (SEC) Ben Henley,
KI4IGX; Florida Department of Emergency Management Telecommunications
ministrator Ben Bass, KI4OEE; Northern Florida SEC Karl Martin, KG4HBN;
Southern Florida SEC John Wells, W4CMH; West Central Florida Assistant SEC
Brad Haag, KM4VRU, and FDLE Statewide Communications Coordinator Nick
Simoncini, KG4NJS.
If agreed upon, the MOU would make ARES and Amateur Radio a valid resource
that can be easily requested during an incident.
"For the first time ARES will be integrated into the state communication
team," said West Central Florida Section Emergency Coordinator (SEC) Ben
Henley, KI4IGX.
To facilitate deployment of communication resources more effectively, the
three Sections have previously agreed to work as a single entity during an
incident. Also discussed was the necessity of changing the way ARES
volunteers are credentialed, trained, and deployed.
"This is a team effort," said Northern Florida SEC Karl Martin, KG4HBN. SECs
and state leaders anticipate working together in the future to overcome
shortcomings in disaster and emergency preparation to ensure an effective
response when Amateur Radio support is requested.
FCC Agrees to 90-Day Pause in Consideration of WT Docket 16-239
It has been almost 6 years since the ARRL requested the FCC to consider
changes to the Amateur Radio digital rules in 11-708 and almost 3years since
ARRL filed comments in the resultant proceeding, identified by the FCC as
16-239.
The Commission's proposed changes differed from the ARRL's initial filing
and caused ARRL to be concerned about possible interference to current users
resulting from the deletion of ARRL's requested 2.8 MHz bandwidth
limitation. Due to those concerns, ARRL filed comments with the FCC opposing
the deletion of the requested bandwidth.
Since ARRL's initial filing, many individuals and groups have commented to
the FCC and publicly regarding issues and potential consequences they
passionately believe are implicated by the FCC's proposals embodied in
16-239/11-708. ditionally, in the six years since the initial filing of
11-708, new information has been presented by individuals and groups who
support and oppose the FCC's proposed adoption of 16-239.
Due to the time that has elapsed since ARRL's initial digital rules change
request, the new information that has become available and the extent of
both support and opposition to the proposed rules change, ARRL asked the FCC
to grant a delay in its consideration of the proposed rules change to
provide the League the opportunity to clarify the issues and determine
whether a consensus can be reached on some or all of the issues raised by
the FCC's proceeding.
At ARRL's request, the FCC Staff has agreed to a 90-day pause in the
consideration of WT Docket 16-239.
