SB QST ARL ARLB017
ARLB017 ARRL Files Comments Against "Seriously Flawed" HF Rules
Petition

ARRL, as part of its mission to protect Amateur Radio, has filed
comments against a proposal 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
with the Federal Communications Commission (FCC). ARRL responded on
behalf of its members and the 760,000 licensees of the Amateur Radio
Service in the US.

The petition can be found online at,
.

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.

ARLB016 Filers Seek Extension on Shortwave Petition. ARRL to File
Comments.

Since May, ARRL has been reviewing the rules proposed in a petition
before the Federal Communications Commission (FCC) from the
"Shortwave Modernization Coalition" (SMC). The ARRL Laboratory has
been studying the petition out of concern for potential interference
to Amateur Radio communications.

Comments on the petition, RM-11953, were due to FCC by July 31, 2023
(see,

) . However, a 30-day extension of time was requested by both
Skywave Networks LLC and FlexRadio Systems.

The timely request from Skywave automatically triggered an extension
to the filing deadline. Under FCC rules, when a request for
extension is made within the appropriate timeframe, commenters may
file comments until a date set by FCC when it rules on the extension
request, or no earlier than two business days after the FCC
decision. On Monday, July 31, the FCC denied the request for
extension. Comments therefore may continue to be filed through
Wednesday, August 2.

In its petition, SMC, a group that appears to represent high-speed
stock trading interests, has proposed amending the FCC Part 90 rules
to allow introduction of high-power digital communications to the
shortwave spectrum that in many instances is immediately adjacent to
the amateur HF bands.

ARRL's comments on the matter will be based on the analysis by its
laboratory and guided by its experienced Washington, D.C. regulatory
affairs counsel. ARRL will use the extension to best represent the
interests of its members and the Amateur Radio Service.

ARLX008 Hurricane Watch Net Seeks Bilingual Net Control Operators

ARLX008 Hurricane Watch Net Seeks Bilingual Net Control Operators

The Hurricane Watch Net (HWN) is looking for new members who are
willing to train to become Net Control Operators. HWN is especially
interested in recruiting bilingual operators who are fluent in
Spanish and English or French/Creole and English. Net Control
responsibilities can entail hours of duty to ensure all received
ground-truth weather reports are forwarded directly to the National
Hurricane Center in Miami.

The net generally activates whenever a system has achieved hurricane
status and is within 300 statute miles of a populated landmass. This
can vary, however, due to the forward speed and intensity of a
storm, or at the request of the forecasters at the National
Hurricane Center. Once activated, the HWN continuously operates
until a storm is no longer a threat to life and property.

The mission of the net is to disseminate the latest advisories
issued by the National Hurricane Center, and to obtain real-time,
ground-level weather conditions and initial damage assessments from
amateur radio operators in the affected areas. The net then relays
that information to the National Hurricane Center by way of WX4NHC,
and when required, the Canadian Hurricane Centre.

It also functions as a backup communication link for the National
Hurricane Center, National Weather Service Forecast Offices, the
Canadian Hurricane Centre, Emergency Operations Centers, emergency
management agencies, non-governmental organizations, and other vital
interests that can involve military relief operations. Such
operations can be involved in the protection of life and property
before, during, and after a hurricane event.

HWN Manager Bobby Graves, KB5HAV, says training will be provided and
each candidate will go through a probationary period with a mentor.
Graves, an ARRL member, says an applicant's station must be
reliable. "While having a tower, beam, and/or amplifier is not a
requirement, your station must allow you to hear and be heard.
Therefore, directional antennas and amplifiers are preferred," he
said.

The net coverage area includes the hurricane-prone areas of eastern
Canada, the US East Coast, the Gulf of Mexico, Central America, and
the Caribbean. The net specifically seeks applicants in the
middle-to-western sections of the US, Canada, Central America, and
the Caribbean. "As always, the HWN is hoping for a quiet season, yet
[we are] prepared for the worst," said Graves.

ARLB015 Commercial Interests Petition FCC for High Power Allocation
on Shortwave Spectrum

The ad hoc group "Shortwave Modernization Coalition" petitioned the
Federal Communications Commission (FCC) to allow data communications
on multiple bands within the HF 2 - 25 MHz range with up to 20 KW,
including in bands immediately adjacent to spectrum allocated to the
Amateur Radio Service. This group appears to represent high-speed
stock trading interests.

The FCC has assigned it RM-11953. Comments are due by July 31, 2023,
and reply comments by August 15.

While the petitioners exclude the amateur bands, high power
operations on immediately adjacent bands are proposed. The ARRL is
reviewing the petition.

Space Weather News sent this alert on June 29:

"BIG SUNSPOT ALERT: One of the biggest sunspots in years is directly
facing Earth. AR3354 is 10 times wider than Earth and about 1/3rd
the size of the historical Carrington sunspot. It's so big,
observers in Europe and North America are seeing it naked eye
through the smoke of Canadian wildfires. Earth-directed flares are
likely in the days ahead."

See https://spaceweather.com/ for continuing coverage.

Conditions were favorable over the Field Day weekend, with the
exception of a brief period when the planetary K index rose to 5 on
Saturday night. This is mentioned in the commentary by OK1HH which
follows.

There were five new sunspot groups on June 23, two more on June 24,
another on June 26 and another on June 27.

Average daily sunspot numbers were up, and solar flux was down.

Average daily sunspot number rose from 143 to 170, and average daily
solar flux declined slightly from 165.4 to 160.3.

This is unexpected, because we normally see these values track
together.

Predicted solar flux is 150 on June 30 through July 5, 155 on July
6, 135 on July 7-8, then 145, 155, 160, 165 and 170 on July 9-13,
175 on July 14-18, 170 on July 19-21, then 160, 150, 145, 145, 140
and 135 on July 22-27, then 130 on July 28 through August 1, 135 on
August 2-4, then 145, 155, and 165 on August 5-7. Flux values may
continue to rise to a peak of 175 before mid-August.

Predicted planetary A index is 8, 15 and 10 on June 30 through July
2, 5 on July 3-7, 12 and 8 on July 8-9, 5 on July 10-11, then a
stormy 20 and 30 on July 12-13, 8 on July 14-23, 12 on July 24-25, 8
on July 26-27, 12 on July 28-29, 8 on July 30, 5 on July 31 through
August 3, 12 and 8 on August 4-5, 5 on August 6-7, then 20 and 30
again on August 8-9. Note that recurring stormy conditions are
predicted at one solar rotation, which is about 27.5 days, following
the July 12-13 prediction.

The above predictions are from forecasters Thompson and Kiser at the
USAF space weather group.

Weekly Commentary on the Sun, the Magnetosphere, and the Earth's
Ionosphere June 30 to July 06, 2023 from F.K. Janda OK1HH.

"In the solar X-ray field during June we could observe the most
significant solar flare so far: X1 in the active region AR3341. It
happened on June 20 at 1709 UTC near the southeastern limb of the
solar disk. In the region where the Sun was high, it caused the
Dellinger Effect, https://bit.ly/3NA61kT .

"The same sunspot group was also the source of the M4.8 flare two
days later. It ejected a CME, but not toward Earth.

"Nevertheless, its passage close to Earth probably caused an
increase in geomagnetic activity on the evening of 24 June.
Theoretically, it could also have been a CME from the X1 eruption of
20 June.

"On June 26, we were surprised by sunspot group AR3354 just above
the solar equator and east of the central meridian. It did not exist
the day prior. Over the next two days its area grew to ten times the
size of the Earth, making it easily observable by the naked eye.

"Significantly, its magnetic configuration changed to
beta-gamma-delta, which is enough energy for powerful solar flares.

"The geomagnetic field has been quiet to unsettled so far.

"AR3354 will be pointed directly toward Earth in the next few days,
so it looks like the next disturbance could begin on July 1. And of
course, a possible large flare could cause a Dellinger Effect
throughout the whole HF spectrum."

"I have been an active ham since 1956 and on the Mississippi coast
since 1971. This year has strengthened my belief in an old
observation.

"There is/was a dome of high pressure that moved from over Texas to
now over me. Before it moved east, I was able to take part in the 6
meter propagation to Europe.

"Since it moved over me, the DX Maps page shows a gap in the DX
propagation from northern Florida to central Louisiana. ?This is not
the first time I have seen it happen, but the new generation of TV
weather persons presented a picture of the dome of high pressure
that coincided with my propagation observations. Suspicions
confirmed?

"Years ago, on 2 meters I noticed that propagation followed weather
fronts up the east coast. Thanks for reading this and perhaps
someone younger than me has already done the research."

"Had been out with our dog. Saw WQ0P PSK flags for PY2XB. Turned on
radio at home with dipole. PY2XB was loud. Really loud. Also copied

an hour. Like a pipeline. Saw him work a few 5s and 0s. KC0CF worked

our summer. This mode works for D2UY (Angola), 3B9FR (Rodrigues

The FCC Universal Licensing System (ULS) has resumed operations,
including the Electronic Batch Filing system (EBF).

As of June 27, 2023, all systems have been reported to be working.
However, visitors to the website will see a message referring them
to Public Notice DA 23-529 for additional information and guidance
on filing deadline extensions.

The systems were first reported unavailable on June 9, 2023. On
Friday afternoon, June 23, the EBF system was restored. All VEC
organizations use that system for filing exam sessions, individual
applications, and club license applications. ARRL VEC staff worked
late into Friday night to ensure all backlogged sessions and
application files were transmitted to the FCC before the weekend.
Approximately 350 backlogged files were successfully submitted to
and processed by the FCC before the system's normal shutdown at 8
PM.

ARRL is still monitoring the ULS system, and any further updates
will be available at ARRL News.
