ARRL Files Comments Against "Seriously Flawed" Shortwave Rules Petition
ARRL, as part of its mission to protect Amateur Radio, has filed comments
against a proposal
<http://www.arrl.org/files/file/FCC%20Documents/ARRL%20Opposition%20FCC%20RM-11953%2008_2023.pdf>
that would introduce high-power digital communications to the shortwave
spectrum that in many instances is immediately adjacent to the Amateur HF
bands.
The "Shortwave Modernization Coalition" (SMC), which represents certain
high-frequency stock trading interests, filed the petition
<https://www.fcc.gov/ecfs/document/1042840187330/1> with the Federal
Communications Commission (FCC). *(Previous coverage can be found on **ARRL
News*
<https://www.arrl.org/news/commercial-interests-petition-fcc-for-high-power-allocation-on-shortwave-spectrum>
*.)* ARRL responded on behalf of its members and the 760,000 licensees of
the Amateur Radio Service in the US.
The ARRL Laboratory performed a detailed technical analysis over several
months to determine if the proposed rules would affect operations on the
bands allocated to Radio Amateurs that are inter-mixed with the Part 90
bands in the spectrum in question.
ARRL's analysis determined that, if the proposed rules are adopted, the new
operations inevitably will cause significant harmful interference to many
users of adjacent and nearby spectrum, including Amateur Radio licensees.
Ed Hare, W1RFI, a 37-year veteran of the ARRL Lab and internationally
recognized expert on radio frequency interference, was the principal
investigator on the study. Hare concluded the petition should not be
granted. "This petition seeks to put 50 kHz wide, 20,000-watt signals
immediately next to seven different amateur bands with weaker protections
against interference than required in other services," said Hare.
In its formal opposition, ARRL stated, "That destructive interference would
result if operations commenced using anything close to the proposed maximum
levels."
ARRL's filed comments highlight flawed analysis and incomplete data
submitted by the petitioners. It noted the petitioners "...significantly
understate the harmful interference that is not just likely, but certain,
if the rules proposed by SMC are adopted as proposed. It is noteworthy that
SMC's proposed rules would provide less protection than the much-lower
power amateur radio transmitters are required to provide Part 90
receivers." ARRL's opposition also noted that there was no reported tests
conducted with Amateur or other affected stations, but referenced a
spectrum capture in the Comments filed with the Dayton Group that showed
actual interference into the Amateur 20-meter band from one of the High
Frequency Trading experimental stations.
Part 90 HF rules currently authorize a maximum signal bandwidth equal to a
voice communications channel, at up to 1000 W peak envelope power (PEP).
The petition seeks multiplication of signal width, greater transmitted
power, and weaker rules that protect users of adjacent spectrum. ARRL's
comments expose the likely fallout:
"Incredibly, notwithstanding the significant increase in potential
interference that would result from using digital schemes with 50 kHz
bandwidths and 20,000 watts of power, SMC also proposes to substantially
lessen the protections required to protect adjacent and neighboring
licensees. SMC proposes [out-of-band emissions] limits that offer less
protection than the existing Part 90 limits and would actually permit no
attenuation (0 dB) at the edge of adjacent allocations, many of which are
bands allocated to and heavily used in the Amateur Radio Service.
Consistent with lessening protections while increasing the potential for
harmful interference, SMC also proposes a lower limit for spurious
emissions. SMC would reduce the existing protection of -73 dB for the
applicable 1000-watt power limit to just -50 dB protection for their
proposed 20,000-watt limit. Due to the much wider 50 kHz proposed
bandwidth, the resulting interference would penetrate deep into the
adjacent Amateur bands."
The proposal has been assigned FCC Docket No. RM-11953. While the period
for commenting on the petition has now closed, replies to comments in the
record may now be submitted.
Hundreds of licensed Radio Amateurs filed comments in the Docket,
expressing overwhelming opposition to the proposal. Those interested may
read ARRL's full comments and the results of the technical analysis, which
are included in the filing. "If granted as written, this would be
devastating to Amateur operation for many tens of kHz into our bands," said
Hare.
ARRL will continue to advocate for its members and the Amateur Radio
Service in this proceeding.

Amateur Radio Operators Can Help with HAARP Experiment
The High-frequency Active Auroral Research Program (HAARP) will host more
than 50 researchers at their Alaska facility from August 1 -14, 2023, for
the resumption of a science summer school that will conduct 30 experiments
over a span of two weeks.

The Polar Aeronomy and Radio Science (PARS) summer school was last held
more than 10 years ago. Its return is part of a 5-year, $9.3 million
National Science Foundation grant awarded to the University of Alaska
Fairbanks in 2021. PARS is a group of more than 50 researchers committed to
meeting the growing demand for skilled scientists and engineers with
knowledge of the special effects that occur in the ionosphere at high
latitudes.
Ghosts in the Air Glow website <https://ghostsintheairglow.space/>.
One of the experiments, Ghosts in the Air Glow by Canadian artist Amanda
Dawn Christie, will give amateur radio operators and shortwave listeners an
opportunity to help with on-going geospace research. This transmission art
project will begin on Monday, August 14, 2023, and use the HAARP
Ionospheric Research Instrument to mix audio and images from the transition
between Earth's atmosphere and outer space. They will then be received and
decoded via software-defined radio. Amateur radio operators and shortwave
radio listeners around the world are invited to tune in and submit
reception reports.
Event information, including transmission times, frequencies, modes, and
report submission guidelines, is available at the project's website, Ghosts
in the Air Glow <https://ghostsintheairglow.space/>. Each experiment
participants will receive a QSL card.
"The return of PARS and these experiments marks a milestone for HAARP and
the geospace communities," said HAARP Director Jessica Matthews.

National Lighthouse Day 2023
National Lighthouse Day is unofficially Monday, August 7, 2023
<https://lighthousefoundation.org/national-lighthouse-day/>, and the US
National Lighthouse-Lightship Weekend (NLLW) will occur on August 5 - 6.
National Lighthouse Day and NLLW celebrate the anniversary of the
establishment of the United States Lighthouse Service, and they honor
lighthouses, lightships, and the commitment and service of those who tended
America's lights for generations. The Amateur Radio Lighthouse Society
(ARLHS)
<https://www.bing.com/ck/a?!&&p=d66cc0f97534850eJmltdHM9MTY5MDkzNDQwMCZpZ3VpZD0xZjRjOThkZS1kNDE5LTYzZjctMjYxZi04YWEyZDVjYTYyZTAmaW5zaWQ9NTE4Mg&ptn=3&hsh=3&fclid=1f4c98de-d419-63f7-261f-8aa2d5ca62e0&psq=Amateur+Radio+Lighthouse+Society+(ARLHS)+&u=a1aHR0cHM6Ly9hcmxocy5jb20v&ntb=1>,
founded by James H. Weidner, K2JXW (SK), will be operating their BeaconBot
website for email contacts and asking amateur radio operators to
participate by contacting lighthouses across the United States.
The suggested calling frequencies for SSB are 1.830, 3.530, 7.030, 10.130,
14.030, 18.070, 21.030, and 28.030. On CW, they're 1.830, 3.530, 7.030,
10.130, 14.030, 18.070, 21.030, and 28.030.
These frequencies can be crowded and are only suggestions. Amateur radio
operators can use any clear frequency +/- 20 kHz of these suggestions. For
digital modes, common operating frequencies are used. On VHF and UHF,
repeater operation is allowed, but using the national calling frequencies
is encouraged. ARLHS advises operators to be courteous, use good operating
practices, and listen before they transmit. The ARLHS World List of Lights
(WLOL) <http://wlol.arlhs.com/>, which was updated on June 19, 2023, is a
comprehensive collection that contains information on 15,527 lighthouses in
234 amateur radio call areas. You can also find the times and dates of
operation for the special events on the website.
The International Lighthouse Lightship Weekend 2023 <https://illw.net/>
(ILLW) will take place on August 19 - 20. Each year ILLW attracts more than
500 lighthouse entries located in at least 40 countries. There are few
rules, and it is not a usual contest type event. Participation is also free
and, there are no prizes for contacting large numbers of stations.

ARRL Podcasts
*On the Air*
* Sponsored by **Icom* <http://www.icomamerica.com/en/>
Passing traffic is a ham radio activity that's nearly as old as ham radio
itself, and getting accurate messages to their destination in a timely
manner takes training and skill. In addition to participating in nets, hams
also have the opportunity to take on ARRL Field Organization positions that
are responsible for traffic. In this episode, "When Messages Matter:
Passing Traffic," we talk to Ethan Hansen, KC1OIP, who fulfills one such
position, Official Relay Station, in ARRL's National Traffic System. Listen
in to learn about what it takes to become an Official Relay Station, how
the position makes a difference in the community, and how it benefits your
amateur radio skills and experience.

*Planning is underway for the 2023 Route 66 On the Air Special Event on
September 9 - 17. *This will be the 24th year of the event has been
running. It was started by the Northern Arizona DX Association (NADXA) and
is now coordinated by the Citrus Belt Amateur Radio Club (CBARC) in San
Bernardino, California. Twenty-one special event stations along the route
from Santa Monica, California, to Chicago, Illinois, are expected to
participate in 9 days of operating opportunities. The special event
celebrates the history of the Mother Road that began in 1926, when US
Highway 66 was established. It was the first major improvement to the link
between the west coast and the nation's heartland. Through stories, songs,
and TV shows, the highway came to symbolize the freedom of the open road,
inspiring many to see America in its entirety. The demise of Route 66 began
in the 1950s, as construction began on the new interstate highway system.
US Route 66 was officially decommissioned in 1986, but today, small
portions of the highway still exist in several states. More information on
the event will be available soon at the Citrus Belt Amateur Radio Club
(CBARC) <https://w6jbt.org/> website or on their Facebook
<https://www.facebook.com/w6jbt/> page.

In Brief...
*On July 28, 2023, members of the* Royal Naval Amateur Radio Society (RNARS)
<http://www.rnars.org.uk/> *commemorated 30 years of being located on the
HMS Collingwood.* The RNARS was founded in 1960, and moved to HMS
Collingwood when the HMS Mercury was decommissioned. The outgoing captain,
now Commodore Paul Sutermeister RN, was instrumental in finding a new home
for the RNARS. The Headquarters Shack in HMS Collingwood has a selection of
transceivers that operate across the radio spectrum via range of antennas.
These allow members to communicate with other radio amateurs around the
world, including by amateur radio satellite. While the majority of RNARS
members are actively serving or are service veterans, there are other
groups who qualify for membership, such as merchant navy and Royal Fleet
Auxiliary personnel and several others with occupations and interests in
maritime affairs. While some of the members have aviation and marine
licenses, they are a friendly mixture of professional and amateur radio
users, with links to both the Royal Air Force and Royal Signals Amateur
Radio societies: - all are affiliate members of the Radio Society of Great
Britain (RSGB). <https://rsgb.org/main/contact/>

The Australian Space Weather Forecasting Centre issued a geomagnetic
disturbance warning at 0233 UTC on August 3, 2023:
"Two recent coronal mass ejections (CMEs) are expected to impact Earth on
UT day 05-Aug, with the second possibly arriving early 06-Aug. G0-G1
geomagnetic conditions may be expected on 05-Aug, with a chance for
isolated periods of G2 towards the end of the UT day on 05-Aug. Geomagnetic
storm conditions may persist over 06-Aug."
Solar activity was up during this reporting week, July 27 through August 2.
Average daily sunspot numbers increased from 128.1 to 154.3, but the
average daily solar flux was about the same as last week, moving from 172.2
to 173.
Geomagnetic indicators were quiet, with the average daily planetary A index
shifting from 11 to 8.3, while middle latitude numbers went from 11.1 to
9.3.
Predicted solar flux is 170 and 165 on August 3 - 4; 160 on August 5 - 7;
155, 145, and 168 on August 8 - 10; 168 on August 11 - 12; 170 on August 13
