On March 4, and March 6, 2026, an Agent from the Los Angeles Office of the FCC’s Enforcement Bureau conducted an investigation and determined, using direction finding techniques, that the radio signals on the frequency 146.415 MHz were emanating from your residence in Bell, California. On March 4, 2026, Agents heard the operator make statements over the air, including “Jack is back,” which identify you as the operator. The Commission’s records indicate that you do not have an amateur radio license and are not authorized to operate on 146.415 MHz. Radio stations, including those operating on 146.415 MHz, must be licensed by the FCC pursuant to the Communications Act of 1934, as amended (Act) and Section 1.903(a) of the Commission’s rules (Rules).1 The only exception to this licensing requirement is for certain transmitters using or operating at a power level or mode of operation that complies with the standards established in part 15 of the Rules.2 Non-licensed operation pursuant to part 15 of the Rules, however, is conditioned upon compliance with all applicable regulations in the subpart.3 All intentional radiators operating pursuant to part 15 of the FCC’s Rules must be certified for use as a part 15 device,4 and failure to operate such device consistent with its authorization violates part 15 of the Rules. The Agent found that the station at the Bell, 1 47 U.S.C. § 301; 47 CFR § 1.903(a). 2 47 CFR §§ 15.1, et seq. 3 47 CFR § 15.1(b). 4 47 CFR § 15.201(b). California location was operating at a power level that exceeds the level permitted by part 15.5 Therefore, this station was operating in violation of section 301 and Section 1.903(a).6 You are hereby warned that operation of radio transmitting equipment without a valid radio station authorization constitutes a violation of the Federal laws cited above and could subject the operator to severe penalties, including, but not limited to, substantial monetary fines, in rem arrest action against the offending radio equipment, and criminal sanctions including imprisonment.7 Because unlicensed operation creates a danger of interference to important radio communications services and may subject the operator to severe penalties, this letter emphasizes the importance of complying strictly with these legal requirements.8 UNAUTHORIZED OPERATION OF THIS RADIO STATION MUST BE DISCONTINUED IMMEDIATELY AND MUST NOT RESUME. You have ten (10) days from the date of this notice to respond concerning your operation of this radio transmitting device. Your response should be sent to the address in the letterhead and reference the listed case number. Under the Privacy Act of 1974,9 we are informing you that the Commission’s staff will use all relevant material information before it to determine what, if any, enforcement action is required to ensure your compliance with Rules.
