On October 27, 2020, the Commission adopted a Report and Order in its proceeding to allow AM radio licensees to broadcast using an all-digital signal. The All-Digital AM Order was released on October 27, 2020, and published in the Federal Register on December 3, 2020. In the All-Digital AM Order, the Commission amended sections 73.402-406 of the rules to permit AM stations to operate using all-digital broadcast signals. Section 73.406 of the new rules requires licensees to notify the Commission using a Digital Notification form, FCC Form 335-AM, when commencing, making certain changes to, or ceasing all-digital operation. The All-Digital AM Order, and the rules adopted therein, became effective January 4, 2021, with the exception of section 73.406, which contains new information collection requirements and therefore had to be approved by the Office of Management and Budget (OMB) under the Paperwork Reduction Act (PRA).
