Storms Generate Busy Times for ARES and the Hurricane Watch Net
The Hurricane Watch Net (HWN) activated on Sunday, September 13, on both 14.325 MHz and 7.268 MHz as Hurricane Paulette was predicted to make landfall on Bermuda the next day as a Category 2 storm. That tour melded into an extended activation in anticipation of Hurricane Sally, which came ashore on the Gulf coast in Alabama on September 16. The slow-moving storm, which diminished to a tropical storm not long after landing, at mid-week was
The HWN stood down at mid-week after 71 hours of continuous operation. HWN Manager Bobby Graves, KB5HAV, said it seem long activations such as these are happening all too often. “I suppose Mother Nature hasn’t been getting the attention she desires,” Graves quipped.
Northern Florida Section Emergency Coordinator Karl Martin, K4HBN, reported on September 17 that Amateur Radio Emergency Service (ARES) teams in his Section were standing down. “We had a total of 4 counties affected by Sally,” he said. “The hardest hit was Escambia county, located at the Alabama/Florida border. The Atlantic is still very busy, but I hope the rest of the season is quiet.”
ARES teams went on alert in other Sections in the region.
The Federal Emergency Management Agency (FEMA) announced on Tuesday that two 60-meter channels had been made available for interoperability between US government stations and US amateur radio stations involved in emergency communications related to the wildland firefighting response in California, Oregon, and Washington, as well as to Hurricane Sally. The interoperability
channels will remain active until the need for them no longer exists:
Frequencies may be modified or added to by FEMA Region 10 for their area or operations due to existing 5 MHz/60-meter interoperability plans for their region.
Amateur radio is secondary on the 5 MHz band and must yield to operational traffic related to wildland firefighting and hurricane response. Although the intended use for these channels is interoperability between federal government stations and licensed US amateur radio stations, federal government stations are primary users and amateurs are secondary users.
The FCC has granted ARRL’s request for a temporary waiver to permit amateur data transmissions at a higher symbol rate than currently permitted by section 97.307(f) of the FCC amateur service rules. The FCC acted to facilitate hurricane and wildfire relief communications within the US and its territories.
ARRL sought the waiver for amateur radio licensees directly involved with hurricane and wildfire relief via HF using PACTOR 4 modems for communication within the US and its territories, relative to several impending hurricane situations and wildfires in the western US. ARRL’s petition noted that Section 97.307(f) of the amateur rules prevents the use of PACTOR 4, a data protocol that permits relatively high-speed data transmission. ARRL also noted that past FCC temporary waivers have allowed this protocol during similar events. The waiver is limited to 60 days.
The Military Auxiliary Radio System (MARS) is following FEMA’s lead on the interoperability channel designations for the wildfire and hurricane response. Army MARS Program Manager Paul English, WD8DBY, says he has alerted all MARS members of the FEMA channel designations and MARS members are prepared to support response efforts as needed.
WX4NHC at the NHC also activated on Sunday in advance of Paulette, monitoring and gathering reports from the HWN on 14.325
and 7.268 MHz and via the VoIP-WX Net on EchoLink WXtalk 7203 Conference and IRLP 9219.
The Caribbean Basin has more in store during this hurricane season. “We are now keeping a close eye on Hurricane Teddy,” Graves said, noting that Bermuda could be affected by another hurricane by late Sunday night or early Monday morning. “Also, we are keeping a close eye on a system that seems to be getting better organized in the southwestern Gulf of Mexico.”
The next named storm will be Wilfred, and after that storms will be designated using the Greek alphabet, starting with Alpha. “If we reach Alpha, it will be the second time in history to use that name,” Graves pointed out. “The first was in 2005.”
ARRL to Seek Changes in FCC Draft Decision on Amateur 9-Centimeter Band
ARRL efforts are under way to preserve amateur radio access to the 3.3 – 3.5 GHz (9-centimeter) band. In an 80+ page draft Report and Order and Further Notice of Proposed Rulelmaking (R&O) in WT Docket 19-348, the FCC announced its intention to delete the 3.3 – 3.5 GHz amateur secondary allocation, subject to a phased withdrawal tied to its licensing of new primary users. According to the FCC, the 3.450 – 3.550 GHz spectrum will be put up for auction as early as December 2021. Incumbent users will be permitted to continue operating in the band until licensing to commercial interests — presumably 5G — begins. That’s estimated to be about 3 months after the spectrum auction concludes, or around mid-2022. No alternative spectrum was proposed to replace the 9-centimeter spectrum for
“We find that removing the existing secondary non-federal allocations from the 3.3 – 3.55 GHz band and clearing these non-federal operations from the band is in the public interest, and therefore, we adopt this proposal,” the draft R&O says. “Because the [Department of Defense and the National Telecommunications and Information Agency] agree that commercial users operating pursuant to flexible use licenses can be accommodated in the 3.45 – 3.55 GHz band at full power, and given continued interest in the 3.3 – 3.45 GHz band for future sharing for flexible-use licenses, we find that retaining the secondary non-federal allocations across this spectrum would hinder the Commission’s ability to offer flexible-use licensing in the future and would undermine the intensive and efficient use of valuable mid-band spectrum.”
“Further, to prevent adjacent-channel issues and to preserve the possibility of additional clearing for flexible use licensing below 3.45 GHz, we find that sunsetting the secondary amateur allocation from the entire 3.3 — 3.5 GHz portion of the band is in the public interest,” the FCC said.
Last February, ARRL filed comments opposing the FCC’s proposal to delete the 3.3 – 3.5 GHz secondary amateur allocation, pointing to amateur radio’s long history of successful coexistence with primary users of the band.
The absolute deadline to submit additional comments on the draft R&O and Further Notice of Proposed Rulemaking via the Electronic Comment Filing System (ECFS) or to contact FCC staff on this issue is Wednesday, September 23 — 7 days before the full Commission’s consideration of the draft for final adoption — in order to comply with FCC “Sunshine Rules.”
In August, the White House and the Department of Defense announced plans to allow for commercial 5G systems to operate in the
The 3.45 – 3.55 GHz segment would be teed up for a spectrum auction that’s expected to commence by the end of 2021. This would mean amateurs would have to cease all operations at 3.45 GHz and above by the middle of 2022 at the earliest, based on an FCC estimate.
The 3.3 – 3.45 GHz segment is not immediately available for reallocation and auction, because more work is needed to accommodate the Department of Defense. Under the rules as proposed, amateur operations will be permitted to continue in this spectrum until sometime in the future, when FCC rulemakings establish new rules and conduct a spectrum auction and commercial licensing.

Analysis Determines We Are in Solar Cycle 25
It’s now official. The solar minimum between Solar Cycles 24 and 25 — the period when the sun is least active — occurred in December 2019, when the 13-month smoothed sunspot number fell to 1.8. This is according to the Solar Cycle 25 Prediction Panel, co-chaired by the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA). We are now in Solar Cycle 25, with peak sunspot activity expected in 2025, the panel said. The panel expressed high confidence that Solar Cycle 25 will break the trend of weakening solar activity seen over the past four cycles.
At 11 years, Solar Cycle 24 was of average length and had the fourth-smallest intensity since regular record-keeping began in 1755, with what is considered Solar Cycle 1. It was also the weakest cycle in a century. At solar maximum in April 2014, sunspots peaked at 114 for the cycle, well below the 179 average.
Solar Cycle 24’s progression was unusual. The sun’s northern hemisphere led the sunspot cycle, peaking more than 2 years ahead of the southern hemisphere sunspot peak. This resulted in fewer sunspots at solar maximum than if the two hemispheres were in phase.
For the past 8 months, activity on the sun has steadily increased, indicating that we have transitioned to Solar Cycle 25, forecast to be a fairly weak cycle — about the same as Solar Cycle 24. Solar Cycle 25 is expected to peak in July 2025, with a predicted 115 sunspots.
“How quickly solar activity rises is an indicator on how strong the solar cycle will be,” said Doug Biesecker, the NOAA-NASA panel co-chair and a solar physicist at NOAA’s Space Weather Prediction Center (SWPC). “Although we’ve seen a steady increase in sunspot activity this year, it is slow.”
“While we are not predicting a particularly active Solar Cycle 25, violent eruptions from the sun can occur at any time,” Biesecker added.
Before Solar Cycle 25 peaks in 2024, NOAA is slated to launch a new spacecraft dedicated to operational space weather forecasting. The Space Weather Follow-On L-1 observatory (SWFO-L1) will be equipped with instruments that sample the solar wind, provide imagery of coronal mass ejections, and monitor other extreme activity from the sun in finer detail than before. NOAA’s next Geostationary Operational Environmental Satellite (GOES-U) is also scheduled to launch in 2024. GOES-U will carry three solar monitoring instruments, including the first compact coronagraph, which will help detect coronal mass ejections. Enhanced observations of the sun from these satellites will help improve space weather forecasting.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: As detailed elsewhere in this edition of The ARRL Letter (see Analysis Determines We Are in Solar Cycle 25), this week’s big news was that scientists have pinned down the Solar Cycle 24 minimum to December 2019 — and the start of Solar Cycle 25.
The reason behind the delay in announcing this is the nature of moving averages, which, in this case, is a smoothed sunspot number derived from arithmetical averaging of sunspot numbers over 1 year — i.e., half the numbers before December, and half after December — to derive a mid-point average.
Over the September 10 – 16 reporting week, the average daily solar flux was 69.2 — no significant difference from the previous week. Average daily planetary A index was 5.3, up from 4.4 the previous week. Average daily mid-latitude A index went from 4.9 to 5.4.
Predicted solar flux for the next 45 days (September 17 – October 31) remains 70, the same as reported in recent bulletins.
Predicted planetary A index is 5 on September 17 – 22; 8, 10, 15, 10, 25, 15, and 10 on September 23 – 29; 5 on September 30 – October 14; 8 on October 15 – 16; 5 on October 17 – 19; then, as earlier, 8, 10, 15, 10, 25, 15, and 10 on October 20 – 26,and back to 5 on October 27 – 31.
Sunspot numbers for September 10 – 16 were 0, 0, 0, 0, 0, 0, and 0, for a mean of 0. The 10.7-centimeter flux was 69.3, 68.7, 69.3, 69.8, 68.9, 68.8, and 69.5, with a mean of 69.2. Estimated planetary A indices were 2, 3, 5, 6, 11, 7, and 3, with a mean of 5.3. Middle latitude A index was 2, 2, 6, 7, 10, 8, and 3 with a mean of 5.4.

International Telecommunication Union Releases 2020 ITU Radio Regulations
The International Telecommunication Union (ITU) has published the 2020 ITU Radio Regulations — the international treaty governing the global use of RF spectrum and satellite orbits. The publication contains the complete texts of the Radio Regulations adopted during World Radiocommunication Conference 2019 (WRC-19), held last year in Sharm El Sheikh, Egypt. Available in all six of ITU’s official languages, the 2020 ITU Radio Regulations are in effect for all signatory parties on January 1, 2021. Electronic versions are free, and the “traditional f
“The publication of the Radio Regulations is the culmination of the hard work and intense deliberations that took place during WRC-19,” said ITU Secretary-General Houlin Zhao. “Efficient and economical use of the naturally limited radio-frequency spectrum is key to ensuring we bring the benefits of connectivity and digital transformation to people everywhere. The ITU Radio Regulations are a vital vehicle for this endeavor.”
The ITU said that, when it comes to allocating radio frequencies, including sharing and harmonizing their use for different purposes, the Radio Regulations are the ultimate tool. “They ensure the use of the RF spectrum is rational, equitable, efficient, and economical, all while aiming to prevent harmful interference between different radio services,” the ITU said.
Ham Radio Exams are Not Going Away in Brazil After All
Amateur radio examinations are not being eliminated in Brazil. A notice that the country’s telecommunications regulator ANATEL released recently was intended to prompt discussion and elicit comment on the idea, but it prompted confusion too. On September 10, ANATEL responded to a letter from Brazil’s national amateur radio society, LABRE, that expressed concern regarding the proposal to scrap amateur radio exams. ANATEL told LABRE that no such change is in the works,
“With respect to the merit presented in the correspondence, this will be analyzed and considered by the technical team of this agency [i.e., ANATEL] in the finalization of the regulatory impact analysis report and the respective regulatory proposal, if any,” ANATEL told LABRE.
Henrique Gravina, PU3IKE, contacted ARRL to offer his take on the confusion. He said many people have complained to ANATEL over the years about amateur exams. When ANATEL considers that a particular issue raised represents a problem area, it selects a complaint to use as a starting point for discussion. This is akin to a Petition for Rulemaking (PRM) that the FCC might “put on notice” to invite comment after a suggested change in the rules.
“Portuguese is a difficult language, even for natives, and it gets worse when we speak and write in legal terms and in bureaucratic processes that are very complicated,” Gravina allowed. “Hams who are not law students or lawyers read the [proposal] and did not understand what was happening.”
LABRE has said it was satisfied with ANATEL’s response and will continue to collaborate with the agency to help modernize the regulatory framework that governs amateur radio in Brazil.
Due to the COVID-19 pandemic, some changes have already come about in the form of online exams for two license classes — A and C. Brazil retains a 5 WPM Morse code requirement for the class B license, and that has not been made available online. Applicants must have 1 year of experience as a class B licensee to sit for the class A exam. The Morse code exam can only be taken at an ANATEL agency office, available in most Brazilian states. — Thanks to Henrique Gravina, PU3IKE
