FCC 73.61 Revised as of December 4, 2012
Goto Year:2011 |
§ 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.
