Section 90.179, Shared Use of Radio Stations

Section 90.179 requires Part 90 licensees that share use of their private land mobile radio (PLMR) facility on a non-profit, cost-shared basis keep a written sharing agreement as part of the station records. The written agreement would set out: the method of sharing, the components of the system which are covered by the sharing arrangements, the method by which costs are to be apportioned, and acknowledgement that all shared transmitter use must be subject to the licensee's control. These requirements are necessary to identify users of the systems should interference problems develop. It is also used by the FCC to investigate interference complaints and resolve interference and operational complaints that may arise among the users.
