  • WCOJ(AM) are licensed to operate on 1420 kHz. On January 29, 2004, the staff granted Metro Radio a construction permit authorizing the Station to increase its daytime power from 10 to 22 kilowatts and nighttime power from 1.7 to 60 watts, utilizing a directional antenna system. The permit fully protected the licensed WCOJ(AM) facilities from interference in accordance with Sections 73.187 and 73.37(a) of the Commission's Rules (the ``Rules''). During construction and testing of the modified facilities, Metro Radio sought and received special temporary authority (``STA'') under Section 73.1615 of the Rules to operate with the facilities authorized in the Construction Permit in order to make final transmission system adjustments and take proof of performance measurements. Metro Radio completed construction of

  • characteristics of AM broadcasting and thus provide the potential for improving AM service in the near future as well as in the long term.'' 7. In the AM service, mutual exclusivity may occur during three operational timeframes: daytime, critical hours, and nighttime. Prohibited daytime contour overlap is determined by Section 73.37 and critical hours mutual exclusivity by Sections 73.37 and 73.187. Finally, AM Improvement Report and Order establishes three classes of nighttime interference contributors: (a) a high-level interferer is defined as a station that contributes to the fifty percent exclusion root-sum-square (``RSS'') nighttime limit of another station; (b) a mid-level interferer is defined as a station that enters the twenty-five but not fifty percent RSS of another station and (c) a

  • which applications will cause unacceptable nighttime interference to other stations.). According to SRC, applications which enter the RSS calculation of other applications are only mutually exclusive if the ability of one of the facilities to provide principal community interference free service is also eliminated. We disagree. The staff properly applied the relevant AM interference rules (47 C.F.R. §§ 73.37, 73.182, 73.187) in making its mutual exclusivity determinations. See, e.g., Nelson Enterprises, Inc., Memorandum Opinion and Order, 18 FCC Rcd 3414 (2003). The Commission recognized that limiting pre-auction analysis of all filed applications to a determination of mutual exclusivity could result in ``applicants, whose technical proposals are unacceptable, participating and perhaps prevailing in an auction'' and, therefore, the Commission considered but rejected

In the AM service, mutual exclusivity may occur during three operational timeframes: daytime, critical hours, and nighttime.
