FCC Legacy CORES System to be Retired

The Federal Communications Commission (FCC) will retire the Legacy version of its COmmission REgistration System (CORES) on July 15, 2022. CORES is the FCC's public-facing database that enables and tracks certain types of FCC and FCC applicant actions, including amateur radio applications and licenses. Its implementation has enabled routine amateur applications and licenses to be issued overnight instead of over weeks, as was the case with earlier methods. ARRL The National Association for Amateur Radio® advises the amateur radio community to transition to the updated version of CORES as soon as possible.

In essence, CORES is designed to identify those who hold certain types of FCC licenses and FCC authorizations, including amateur licenses, and organize them in an easily accessible manner under a common FCC Registration Number (FRN) regardless of whether one holds a single such authority or thousands. The new CORES, in addition to assigning individual FRNs, allows holders of multiple FRNs to aggregate them under a single account where the licenses and authorization, fees and payments, and related actions can be administered from within the same account.

In effect, new CORES can be conceptualized as an electronic interactive file folder. The updated version of CORES has been available since 2016, and now its use will be mandatory for all amateur licensees when submitting amateur-related applications.

Starting on July 15, 2022, the Legacy CORES website will re-direct users to the Commission's updated CORES site. Although some functionalities in the old system will continue to work for a short time, the FCC has urged all users to transition to the updated CORES system to take advantage of its enhanced security and functionality.

Register with the FCC

Licensees that do not already have an FCC CORES Username Account must create one with a unique username (a valid email address) and password. After creating the account, when logged in, users should associate their existing FRN or FRNs with this account. Instructions for doing so are on the FCC Registration Help page. One's FRN is printed on all current amateur applications and licenses, and will not change. FRNs can also be found by looking up one's call sign in the Commission's ULS ( or by using the FCC's advanced search page.

The FCC has posted Tutorial Videos to assist with the transition. ARRL VEC Manager Maria Somma, AB1FM, recommends viewing the videos "Getting Started With the New CORES," which explains how to register for a CORES Username Account, and "Associating an FRN to a Username," which instructs Legacy CORES users on how to link one or more existing FRNs to a username. FCC CORES Registration Instructions can also be found on the ARRL website.

Additional information is available on the FCC website or by calling the FCC Licensing Support Center at (877) 480-3201, Option 4, and on the FCC's e-support page.

Hawaii Hurricane Emergency Communications Drill Set for July 16, 2022

Makani 'Ino is Hawaiian for "big wind" and the name of Hawaii's Amateur Radio Emergency Service® (ARES®) upcoming hurricane emergency communications drill. The drill will assess the ability of amateur radio operators to establish emergency radio communications in the event of a severe infrastructure failure due to hurricane-like conditions.

In addition to testing two-way radio communications, the drill will also use Winlink Global Radio Email® to send and receive messages from surrounding islands and participating agencies. Radio operators will first use radio, then they'll send simulated digital messages using Winlink for reports and requests for assistance.

Hawaii ARES Public Information Officer Michael Miller, KH6ML, said, "With this drill, we are also trying to increase the level of participation, so that all operators have the chance to develop the skill sets for real-world situations." Miller added, "It is important for younger, or new, amateur radio operators to know they can use their digital skills in emergency situations."

Miller also said they will be sending after-action reports to participating agencies, such as the National Weather Service and the American Red Cross, to help improve communications using amateur radio technology.

This is the second statewide drill conducted by Hawaii ARES in 2022. Makani 'Ino begins Saturday, July 16, 2022, from 9 AM to noon Hawaii Standard Time.

Sunspot activity increased this week, with average daily sunspot numbers going from 49.1 to 62.6. But oddly, average daily solar flux was down slightly from 105.3 to 103.5.

Taking a longer view, solar activity is stronger than it was a year ago, when the average daily sunspot number was 34.7 and average solar flux was 86.9. reported that a Coronal Mass Ejection (CME) missed Earth on July 1, but it pushed dense solar wind plasma toward us, causing a G1-class geomagnetic storm. In the few hours past midnight UTC, planetary K index was 4, then 5. Alaska's high latitude college A index was 25 on July 2.

Predicted solar flux for the next month is 120 on July 7 - 8, 130 on July 9 - 11, then 120, 125, 110, and 108 on July 12 - 15, then 110, 100, 95 and 98 on July 16 - 19, 95 on July 20 - 21, 98 on July 22 - 23, 100 on July 24 - 25, 102 on July 26, 105 on July 27 - 28, 100 on July 29, 110 on July 30 - 31, 112 on August 1 - 2, 115 on August 3 - 6, 112 on August 7 - 8, 110 on August 9, and 108 on August 10 - 11.

Predicted planetary A index is 14 and 8 on July 7 - 8, 5 on July 9 - 12, 10 on July 13 - 14, then 15, 12, and 10 on July 14 - 17, 8 on July 18 - 21, then 12, 15, 10, and 8 on July 22 - 25, 5 on July 26 - 31, then 8, 25, 12, and 8 on August 1 - 4, and 5 on August 5 - 9.

Sunspot numbers for June 30 through July 6, 2022, were 40, 30, 57, 42, 79, 92, and 98, with a mean of 62.6. The 10.7-centimeter flux was 95.7, 98, 100.2, 102.2, 104.4, 109.4, and 114.6, with a mean of 103.5.

Estimated planetary A indices were 5, 7, 19, 8, 21, 4, and 5, with a mean of 9.8. Middle latitude A index was 5, 8, 17, 11, 18, 4, and 5, with a mean of 9.7.
