National Hurricane Center Amateur Radio Station Annual Test

Updated 5/16/23

The amateur radio station of the National Hurricane Center, WX4NHC (NHC), located on the campus of Florida International University in Miami, will conduct their on-the-air Annual Communications Test on Saturday, May 27, 2023, from 9 AM - 5 PM EDT (1300z- 2100z).

This is the NHC's 43rd year of public service. NHC Amateur Radio Assistant Coordinator Julio Ripoll, WD4R/WX4NHC, reports that the purpose of this event is to test amateur radio equipment and antennas at the NHC as well as operators' home equipment, antennas, and computers prior to this year's hurricane season. The 2023 hurricane season begins June 1 and runs through November 30.

This event is good practice for amateur radio operators worldwide to practice amateur radio communications during times of severe weather.

Ripoll said WX4NHC will be on HF, VHF, UHF, 2- and 30-meter APRS, and Winlink, To contact the NHC's amateur radio station send an email to The subject of the email must contain //WL2K.

WX4NHC will try to stay on the Hurricane Watch Net frequency, 14.325 MHz, for most of the time, as well as 7.268 MHz depending on propagation. They may also change frequencies due to potential QRM.

You may be able to find WX4NHC on HF by using one of the DX spotting networks, such as the DX Summit website at

The VoIP Hurricane Net will also be active from 4 PM - 5 PM EDT (2000-2100z), RLP node 9219/EchoLink WX-TALK Conference node 7203. Visit their website for more information.

WX4NHC will also make a few contacts on local VHF and UHF repeaters, as well as the Florida Statewide Amateur Radio Network (SARnet) system to test station equipment.

QSL cards are available via WD4R with a self-addressed stamped envelope. More information about the NHC is available at their website.

Editors note: A previous version of this article conflated the use of the frequency normally used by the Hurricane Watch Net by WX4NHC with the actual Hurricane Watch Net.

Virginia Beach Amateur Radio Club Receives Commendation

The Virginia General Assembly recently issued a resolution commending the Virginia Beach Amateur Radio Club, W4UG (VBARC).

House Joint Resolution 681 was carried in the Virginia General Assembly by Virginia Beach Delegate Karen S. Greenhalgh. The resolution was co-patroned in the Virginia Senate by the 8th District Senator Bill DeSteph and the 14th District Senator John Cosgrove.

The commendation honored the VBARC for their many community contributions, stating, "the VBARC, an American Radio Relay League Special Service Club, has greatly served the Virginia Beach community for many years by volunteering its time and equipment for emergency and public services, and by providing exceptional aid to both local amateur radio enthusiasts and the community at large through training classes, technical projects, and other activities."

The complete resolution can be read here:

Five members of the VBARC were invited to the House Gallery of the Virginia General Assembly by Delegate Greenhalgh, where the resolution was read on the House Floor before the Virginia House of Delegates.

Delegate Greenhalgh presented the framed resolution to the VBARC at their April 2023 meeting. It was accepted by VBARC Club President Doug Duggan, N4IRK.

Ohio's Rooster Net Has Good Company

Last week's Ohio Rooster Net story in the May 4, 2023, issue of The ARRL Letter brought in two immediate responses regarding some of the longest-running nets.

First, Larry Wheeler, W9QR, reminded us that the Indiana Section Level Traffic Net, formally the Indiana Phone Net, has been active every day with a morning and evening session on the 80-meter band since January 19, 1947.

The ITN started out as an AM net that switched to SSB in the 1960s. The sessions now begin at 0830 AM EST on 3912 kHz and on 3910 kHz for the evening sessions at 2030 PM EST. A typical session may have five to ten pieces of formal traffic, after which a roll call of about 50 stations is called.

Wheeler said all of this is accomplished in about 18 minutes, and then the net is closed. Operators who hear the net for the first time are amazed at its efficiency. Before the days of long-distance telephone service, it was commonplace for the net to handle more than 1,000 messages each month.

Then, Harold Lines, W7DPS, checked in to alert us that on the evening of December 20, 1948, the Oregon Emergency Net (OEN) held its very first official session. "By my calculations, that makes 27,163 daily sessions, including the one we just held tonight. Session number 28,000 should happen on August 18, 2025," said Lines.

The OEN got its start in May 1948, when a combination of melting snow and heavy rains caused unprecedented flooding in the Pacific Northwest. Along with damage throughout the area, the community of Vanport, in the Portland, Oregon metropolitan area was completely destroyed. The incident left about 18,000 people homeless. As a result of the massive amount of health and welfare traffic generated by the flooding, Oregon amateurs decided to form an "organized statewide amateur emergency communications network," according to the OEN's history provided on their website.

Chief Rooster Roy Hook, W8REH, congratulated the OEN in advance for its 75th anniversary coming up in December 2023, and thanked both clubs for their accomplishments. Hook concluded that, "celebrating traditions is key to longevity."

In Brief...

Puerto Rico 's Amateurs Celebrated Dia del Radioaficionado on Tuesday, May 9. "Radio Amateur Day" was marked by a proclamation from Governor Pedro Pierluisi and Secretary of State Omar Marrero. It recognizes the voluntary help amateurs have offered in times of emergency like Hurricanes Irma and María and the 2020 earthquake. Celebrations included a special 2-meter net from the Federación de Radio Aficionados de Puerto Rico (FRA), an ARRL Affiliated Club. May is National Radio Month on the island. Radio amateurs in Puerto Rico are affectionately known as "kapecuatros", the phonetic spelling (in Spanish) of the KP4 prefix.

The 2023 National Hurricane Conference was held April 4 - 5 in New Orleans, just before the start of the hurricane season in June. The event was a forum for education and professional training in hurricane and disaster preparedness. More than 1,500 people attended from around the country. The conference covered all major aspects of hurricane preparedness, response, and recovery. As part of the conference, there was an Amateur Radio Communications Workshop. ARRL Director of Emergency Management Josh Johnston, KE5MHV, and Rob Macedo, KD1CY, Director of Operations, VoIP Hurricane Net and ARRL ARES Eastern Massachusetts Section Emergency Coordinator were featured as speakers.
