Way back in September the Commission approved moment method computer modeling for directional AM proofs, but the rules didn’t go into effect until December 1, 2008 – and even then (as we reported here), they didn’t really go into effect because the application forms on which such proofs must be submitted hadn’t jumped through all the requisite bureaucratic hoops. If that minor technicality stopped any of you from proceeding with preparation and submission of streamlined proofs, your wait is over. The Office of Management and Budget approved the FCC’s modified forms on January 26, and notice of that approval popped up in the Federal Register this morning.  According to that notice, the forms (and associated rules) are effective as of February 5, 2009.
