ARRL proposed rule changes
No newly announced ARRL-origin operating-rule proposal was identified in the October 4–11 ARRL news and Letter material reviewed for this edition.
For background, ARRL's April 11, 2025 comments in FCC GN Docket 25-133 called for an omnibus modernization of Part 97. Among the positions documented there:
- Remove remaining symbol-rate and certain bandwidth restrictions on specified LF and VHF/UHF bands.
- Expand limited HF digital and voice opportunities for Technician licensees, renewing the older RM-11828 petition.
- Reconsider the 80/75-meter subband arrangement under RM-11759.
- Modernize outdated digital-code and third-party-communication provisions.
These are dated advocacy positions. The 2025 filing does not establish their disposition as of October 2026, and it does not authorize different operating privileges. Only adopted, effective FCC rules govern U.S. operation. ARRL's original April 2025 filing
FCC proceedings and rules
RF exposure deadlines approaching
FCC ET Docket 13-84: Comments are due October 22, 2026. Public Notice DA 26-997 seeks information on RF-exposure issues remanded by a federal appeals court. It is a request to develop the record, rather than a final rule imposing new amateur power limits. Official Federal Register notice, September 22
Separate HHS inquiry: Comments are due October 21, 2026, under HHS–OASH–2026–0397. This request covers electromagnetic fields, RF radiation, and wireless technologies. Official HHS notice, September 21
ARRL covered these inquiries on September 25 and said they do not change the RF-exposure requirements presently applying to amateurs. This is an approaching-deadline reminder, not an announcement first issued this week. ARRL explanation
Satellite direct-to-device spectrum proposal
FCC 26-51, ET Docket 26-169: Comments close November 9, 2026; replies close December 7.
The August proposal considers satellite connectivity involving 2400–2483.5 MHz and 5725–5850 MHz, which overlap amateur allocations. Proposed uplinks would use existing Part 15 device parameters; the proceeding also examines downlinks and coexistence. It is an FCC proposal, with no verified basis to label it an ARRL-origin proposal.
It does not itself change amateur privileges. Operators interested in microwave spectrum sharing should review the actual questions and interference framework before commenting. FCC proposal, Federal Register notice and deadlines
Current 60-meter rules
The changes effective February 13, 2026 remain useful operating context:
- General-class and higher licensees have secondary access to 5351.5–5366.5 kHz, with a maximum 9.15 watts ERP and 2.8-kHz bandwidth.
- Four separate legacy channels retain a 100-watt ERP limit.
- The former 5358.5-kHz channel lies inside the lower-power segment. Do not treat it as a fifth 100-watt channel.
ERP is a radiated-power limit and should not be confused with the transmitter's output setting. Consult the rules and station-specific antenna calculation before transmitting. Official final rule, ARRL's January 15 explanation
Space weather and HF outlook
What NOAA observed
NOAA's three-day forecast issued October 11 at 12:30 UTC / 7:30 a.m. CDT reports a greatest observed three-hour Kp of 7, or G3, during the preceding 24 hours. It also reports R2 radio blackouts, with the largest at 15:10 UTC October 10. Its forecast calls for G1–G2 conditions October 11–12 and gives 65% probabilities of R1–R2 blackouts on each of those days, declining to 55% on October 13. These are dated observations and probabilities, not a guarantee of conditions at a particular station. NOAA three-day forecast
The daily records show how the completed October 4–10 observing week developed:
| UTC date | 10.7-cm solar flux (sfu) | Sunspot number | Estimated planetary A |
|---|---|---|---|
| October 4 | 92 | 55 | 36 |
| October 5 | 100 | 58 | 24 |
| October 6 | 113 | 77 | 11 |
| October 7 | 114 | 78 | 6 |
| October 8 | 119 | 69 | 6 |
| October 9 | 121 | 93 | 11 |
| October 10 | 126 | 99 | 46 |
| Seven-day mean | 112.1 | 75.6 | 20.0 |
Means were calculated from the seven listed daily values. Solar data were issued October 11 at 14:25 UTC; geomagnetic data were issued 15:30 UTC. The latter records Kp 7 during October 10. October 11's incomplete daily row is excluded. NOAA daily solar data, NOAA daily geomagnetic data
Forecast through October 18
The longer-range product issued October 11 at 00:00 UTC, equivalent to 7 p.m. CDT October 10, contains this outlook:
| UTC date | Forecast solar flux (sfu) | Forecast planetary Ap |
|---|---|---|
| October 11 | 125 | 32 |
| October 12 | 125 | 22 |
| October 13 | 120 | 24 |
| October 14 | 110 | 12 |
| October 15 | 100 | 5 |
| October 16 | 95 | 5 |
| October 17 | 95 | 5 |
| October 18 | 105 | 5 |
This is a planning forecast. It points toward quieter geomagnetic conditions later in the week, but CME arrivals and evolving solar activity can change that outlook. For near-term decisions, check the newer three-day forecast and current alerts. NOAA 45-day forecast
Practical operating approach
Editorial interpretation, not a band-by-band NOAA forecast:
- October 11–13: Keep plans flexible. Try 20 meters during daylight and 30/40 meters around darkness, and change band or path when conditions deteriorate.
- October 14–18: If the quieter forecast holds, check 17 and 15 meters alongside 20 meters. Continue exploring 40 and 80 meters at night.
- 10 and 12 meters: Listen for actual openings rather than assuming that higher solar flux makes a path usable. This digest does not establish a dependable 6-meter opening forecast.
Geomagnetic storms can disrupt ionospheric propagation; flare-related radio blackouts affect the sunlit side of Earth. These are different mechanisms, so conditions may vary with time, route, and band. NOAA on geomagnetic storms, NOAA on radio blackouts

Emergency communications
Hurricane Isaias activation concluded
NHC's landfall update places Hurricane Isaias near Destin, Florida, at 8:30 p.m. CDT October 9, equivalent to 01:30 UTC October 10, with maximum sustained winds of 105 mph. Official NHC landfall update
The Hurricane Watch Net says it activated October 9 at 12:30 UTC and concluded October 10 at 16:00 UTC. Operators collected and forwarded weather and post-storm reports. Its report thanks users of 14.325 and 7.268 MHz for keeping those frequencies available. This activation had ended before this digest's cutoff. HWN activation report
For subsequent activations, check the net's own announcements. Listen first and give emergency traffic priority.
Contest results in context
The WRTC Sanctioning Committee's September 24, 2026 decision revised the results of WRTC2022, which was held in 2023, and lists I43C as champion. ARRL highlighted the revision in its October 8 Letter. The decision predates this reporting week; the official statement supplies the adjudication and revised standings. WRTC committee decision
