§ 73.61   AM directional antenna field strength measurements.

   (a)  Each AM station using a directional antenna with monitoring point
   locations specified in the instrument of authorization must make field
   strength measurements as often as necessary to ensure that the field at each
   of  those  points  does  not exceed the value specified in the station
   authorization. Additionally, stations not having an approved sampling system
   must make the measurements once each calendar quarter at intervals not
   exceeding 120 days. The provision of this paragraph supersedes any schedule
   specified on a station license issued prior to January 1, 1986. The results
   of the measurements are to be entered into the station log pursuant to the
   provisions of § 73.1820.

   (b)  If  the  AM  license  was  granted on the basis of field strength
   measurements performed pursuant to § 73.151(a), partial proof of performance
   measurements using the procedures described in § 73.154 must be made whenever
   the licensee has reason to believe that the radiated field may be exceeding
   the limits for which the station was most recently authorized to operate.

   (c) A station may be directed to make a partial proof of performance by the
   FCC whenever there is an indication that the antenna is not operating as
   authorized.
