Effective Date for AM DA Rule Changes in Limbo

FCC awaits OMB approval, rather than implement the changes piecemeal

The FCC now says its AM directional antenna rule changes will not take effect Dec. 5.

The Report & Order released in August simplifies traditional proof of performance requirements for directional AMs. The agency is designating moment method modeling as a more efficient substitute for traditional directional AM station field strength proofs, which can be time-consuming and expensive. The agency modified its rules to better protect nearby AMs from nearby tower construction and modification.

Portions of the rule were to take effect Dec. 5 and others would need to wait for approval by the Office of Management and Budget, according to a Federal Register notice from November.

The FCC is now correcting that information, and says the commission will publish a document in the Federal Register announcing when the entire rule change becomes effective.
