The FCC has released a second Report and Order (R&O) and second Further Notice of Proposed Rulemaking (FNPRM) that impacts AM stations, a copy of which is available here.
In the second R&O, the agency adopted rules that permit most AM stations to conduct proof of performance measurements using computer modeling, commonly referred to as the "moment method" or "method of moments." The Commission has made the use of computer-based modeling optional and AM stations may still conduct actual proof of performance measurements. Computer-based modeling, however, can reduce both the time and cost of performing proofs. These rules become effective on December 1.
In the second FNPRM, the Commission seeks comment on its proposal to modify rules on construction of towers near AM stations. Currently, the FCC's rules contain several provisions concerning tower construction near AM antennas. These existing rules, however, impose inconsistent requirements on different towers (i.e., broadcast towers are treated differently than wireless towers), and some towers are excluded entirely from requirements to protect AM stations. Comments in response to the second FNPRM are due 30 days, and reply comments are due 60 days, after publication in the Federal Register.
