The FCC Part 97 rules establishing a new $35 amateur radio application fee go on the books on April 19, but the FCC won’t start collecting the fee “until the requisite notice has been provided to Congress, the FCC’s information technology systems and internal procedures have been updated, and the Commission publishes notice(s) in the Federal Register announcing the effective date of such rules.” When effective, the fee will apply to new, modification (upgrade and sequential call sign change), renewal, and vanity call sign applications, as well as applications for a special temporary authority (STA) or a rule waiver. Fees will be collected per application. The FCC exempted from the fee applications for administrative updates, such as a change of mailing or email address. The FCC proposed a schedule of application and other fees for all services last year.
