ARRL takes exception to FCC Uncertified Transceiver Enforcement Advisory

ARRL has taken a minor exception to the wording of a September 24 FCC Enforcement Advisory pertaining to the importation, marketing and sale of VHF and UHF transceivers and is in discussion with FCC personnel to resolve the matter.

FCC Enforcement Advisory Concerning Two-Way VHF/UHF Radios

On September 24, 2018, the Federal Communications Commisssion (FCC) published Enforcement Advisory No. 2018-03 (the Advisory)—titled Two-way VHF/UHF radios may not be imported, advertised, or sold in the United States unless they comply with the Commission’s rules—in response to “an increase in the manufacturing, importation, advertising, and sale of two-way VHF/UHF radios that are not authorized in accordance with the Commission’s rules.” 1 The Advisory has been published in PDF, DOC, and plain text formats.

One item of note in the Advisory is an Amateur Radio Exception which appears to disallow the use of uncertified devices by Amateur Radio Service (ARS) licensees.
