A licensed operator must measure the operating frequencies of all land-based transmitters at the following times:

Title 47 published on 2014-10-01
The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 47 CFR Part 87 after this date.
In this document, the Commission takes several steps to accommodate the long-term needs of wireless microphone users. Wireless microphones play an important role in enabling broadcasters and other video programming networks to serve consumers, including as they cover breaking news and live sports events. They enhance event productions in a variety of settings—including theaters and music venues, film studios, conventions, corporate events, houses of worship, and internet webcasts. They also help create high quality content that consumers demand and value. In particular, the Commission provides additional opportunities for wireless microphone operations in the TV bands following the upcoming incentive auction, and provides new opportunities for wireless microphone operations to access spectrum in other frequency bands where they can share use of the bands without harming existing users.
In this document, the Commission implemented allocation changes from the World Radiocommunication Conference (Geneva, 2007) (WRC-07) and updated related service rules. The Commission took this action in order to conform its rules, to the extent practical, to the decisions that the international community made at WRC-07. This action will promote the advancement of new and expanded services and provide significant benefits to the American people. In addition, the Commission revised the International Table of Frequency Allocations within its rules to generally reflect the allocation changes made at the World Radiocommunication Conference (Geneva, 2012) (WRC-12).
In this document, the Federal Communications Commission (FCC) revises certain mailing addresses pertaining to satellite emergency radiobeacons which are used to facilitate search and rescue of persons in distress. We update the rules to include the correct mailing addresses for the National Oceanographic and Atmospheric Administration's (NOAA) National Beacon Registration Database, the Radio Technical Commission for Maritime Services (RTCM), the Radio Technical Commission for Aeronautics (RTCA), and the United States Coast Guard (Coast Guard). This Order updates the mailing addresses provided in our rules for NOAA, RTCM, RTCA and the Coast Guard.
