Radio amateurs now have a new tool from ARRL to help answer questions about their stations. Neighbors of amateur radio operators are sometimes concerned about transmissions and radio frequency exposure from amateur stations.

The , with their international counterparts at the Radio Society of Great Britain (RSGB), the Irish Radio Transmitters Society (IRTS), and the Swedish Society of Radio Amateurs (SSA), has developed a new set of guidelines to help amateurs interact with and talk to their neighbors about RF exposure.

Chairman of the ARRL RF Safety Committee Greg Lapin, N9GL, said the new informational PDF found on the ARRL RF Exposure page, , was developed after a year of discussions about RF safety.

"Neighbors may be alarmed by some of the misinformation about RF safety that is available from a variety of sources. By following the exposure regulations from the Federal Communications Commission, we can be confident that our families and neighbors are safe," Lapin said.

Lapin added that RF exposure regulations are based on decades of trustworthy research. He also encouraged all amateur radio operators to perform exposure assessments for their stations to make sure they meet those regulations.

ARRL sought a waiver on behalf of the activators, and the Federal Communications Commission (FCC) has granted it. The allows amateur radio operators to participate in a special event commemorating the 82nd annual National Pearl Harbor Remembrance Day.

, with authority from the US Navy and Southwest Marine Corps Spectrum Office, will honor the sailors and ships previously homeported in San Pedro, California, who were attacked on December 7, 1941. There will be special crossband activations of NEPM, Battleship Iowa's original call sign, on December 6, 7, 8, and 9, 2023.

Using the call sign NEPM, the club will transmit on assigned military frequencies and listen for calls from the amateur radio community on their adjacent bands. NEPM will transmit on 14.375, 18.1625, and/or 21.856 MHz on J3E/USB and/or A1A/CW. (Note: 18.1625 MHz is within US amateur allocations for 17 meters) The club operator will tell participating hams where BIARA will be listening, which will be 10 KHz below the top of each adjacent band when working J3E/USB, or 10 KHz above the bottom of each adjacent band when working A1A/CW. Amateur participants are reminded not to transmit on the NEPM military frequencies. Operations on all 4 days are expected to be from 0700 to 1600 PST (1500 to 2400 UTC).

The FCC stated the grant of the waiver meets the second prong of the waiver standard in section 1.925(b)(3)(ii) in that the event presents a unique opportunity for the amateur and military communities to practice communication skills under the guidance of military officials, which may be useful in the future and serves the public interest.

In addition to the skills gained by amateur operators participating in the test, National Pearl Harbor Remembrance Day has historical significance. It emphasizes the importance of reliable communications and the need to be vigilant in national defense.

If amateur radio operators who wish to participate are licensed in a country outside the US, BIARA advises to check the terms and conditions that govern their respective licenses.

As part of the celebrations for SKYWARN? Recognition Day (SRD) on December 2, 2023, hams will be on the air as WX1AW from the ARRL Radio Laboratory station, W1HQ. ARRL Director of Emergency Management Josh Johnston, KE5MHV, and other amateurs plan to be on the air for several hours Saturday morning and midday.

The event honors all SKYWARN storm spotters and amateur radio operators for their contributions to the National Weather Service (NWS) during severe weather. Amateur radio operators also provide vital communication to the NWS and emergency management teams in other instances when normal communications fail.

"SKYWARN is a perfect example of an opportunity for hams to provide situational awareness for our communities during severe weather. We are happy to participate with our partners at the NWS and look forward to continuing the service provided by amateur radio operators around the country," said Johnston.

For those interested in participating in the operating event, the website is updated with the SKYWARN registration form, mapping form, rules, and information.

SRD was developed in 1999 by the NWS and ARRL. On SRD amateur stations exchange contact information with as many NWS stations as possible on 80, 40, 20, 15, 10, and 6 meters, plus the 2-meter and 70-centimeter bands. Contacts made via repeaters are also permitted. Non-amateur radio spotters can exchange information with NWS offices using social media. To learn how to become a trained NOAA storm spotter, visit .

The Value of Contest Clubs

"Contesting encompasses so much of the hobby," says seasoned contester Craig Thompson, K9CT, in the current episode of the , "from station building, learning how to operate, understanding propagation, knowing the rules, learning from your peers," that there's something in it for every ham radio operator. As current member and former president of the Society of Midwest Contesters, Craig knows the ins and outs of running a contest club and ensuring that the value proposition makes sense to the average member. In this episode, Craig talks about why you might want to get involved with a contest club, what it entails, and how these specialized clubs stir up on-air activity that benefits every ham. This discussion extends the November/December 2023 On the Air, "Joining a Contest Club," by Leanna Figlewski, KC1RMP.

The National Conference of Volunteer Examiner Coordinators (NCVEC) Question Pool Committee (QPC) has removed two General-class license questions. Pursuant to the November 13, 2023, FCC rule change to remove symbol rate restrictions on amateur radio digital emissions (), the QPC of the NCVEC has deleted two questions from the General-class question pool because they are no longer correct. General-class questions G1C08 and G1C10 are withdrawn from the pool effective immediately and should be removed from examinations as soon as possible. Updated question pool files, including the errata and new information, have been posted on the NCVEC General-class question pool web page at The current Element 3 General question pool became effective on July 1, 2023, and it is valid through June 30, 2027. The advises the community to regularly check the NCVEC website at for updates to the question pools, which may include errata and withdrawn questions.

In a ceremony held on November 21, 2023, in Oregon City, Oregon, the Emergency Communications Radio Room in Clackamas County's Disaster Management offices was named in honor of former Section Manager of the ARRL Oregon Section David Kidd, KA7OZO. Kidd is a longtime amateur radio volunteer who stepped down from his role as the County Emergency Coordinator for radio amateurs after 20 years of service. Kidd became the Emergency Coordinator for the Clackamas Amateur Radio Emergency Services? (CARES?) in 2002. Under his leadership, CARES signed a memorandum of understanding with Clackamas County Disaster Management in 2005 that established a strong working relationship between amateur radio volunteers and county disaster management. Kidd's successor, Steve Jensen, KE7GXC, explained, "David built CARES from just a few people to one that has strong cooperation with Clackamas County, city subunits, and a large, active, trained, and committed membership." Interim Deputy Disaster Manager for Clackamas County Jamie Poole announced at Kidd's retirement that the newly established radio room would be named in his honor to recognize his service to the county. CARES is a group of licensed amateur radio volunteers who provide critical communication links during disasters and other major events. For more information about CARES, visit .

Summits on the Air (SOTA) is offering a 10-meter Challenge in 2024. The challenge will run from 0000 UTC on January 1, 2024, to 2359 UTC on December 31, 2024. Solar Cycle 25 is beginning to create regular favorable DX conditions on the higher bands, and early predictions indicate the cycle peak may occur during the summer of 2024. SOTA held a 12-meter Challenge in 2013, and since then, more than 90 associations have been added to the SOTA program, including many in South America, the Caribbean, and Asia. There is excellent potential for DX SOTA activity, and activators are encouraged to consider 28 MHz for their summit operations in 2024. Scoring will be done automatically by the database software. Activations and chases should be entered as normal. The software will note 10-meter QSOs and score them according to the rules. Usual SOTA rules will apply. Multi-band activations can also be entered as normal, and all results will be updated. Qualifying 10-meter QSOs will be scored separately from other SOTA activity. There will be a special 10-meter Challenge results page, and electronic certificates will be issued for all participants with their name, call sign, association, and score. For more information, including the rules for the challenge, visit the website.

The Australian Space Weather Forecasting Centre issued the following Geomagnetic Disturbance Warning #23/74 at 2321 UT on November 29, 2023:

"Several coronal mass ejections (CMEs) are expected to impact Earth on November 30 and December 1, 2023. Two CMEs were observed on November 27 that were expected to arrive on November 30, followed shortly by a very mild, glancing blow from a third. One or possibly two halo CMEs were observed on November 29, which are Earth-directed. It is likely that all or some of these CMEs will combine on their trajectory toward Earth, making it difficult to pinpoint an exact arrival time. However, G3-G4 geomagnetic conditions are possible over this period."
