Federal Communications Commission Washington, D.C. 20554 February 21, 2018 DA 18-167 Chris A Mollish Franklin Square & Munson Fire District P.O. Box 1309 841 Liberty Place Franklin Square, NY 11010 Re: WPKX623 and the use of 453.4625 MHz Dear Mr. Mollish: It has been brought to our attention that the Franklin Square & Munson Fire District is using frequency 453.4625 MHz on authorization WPKX623 for internal, routine, day-to-day operations. A review of our licensing records shows that the Commission issued the original authorization for WPKX623 in October 2000 and Franklin Square & Munson Fire District has timely renewed the authorization since that time. However, since the time of the initial authorization, the Commission has imposed new limitations on 453.4625 MHz. Specifically, 453.4625 MHz is subject to the following limitation: “After December 7, 2000 this frequency is available primarily for public safety interoperability only communications. Stations licensed prior to December 7, 2000 may continue to use this frequency on a co-primary basis until January 1, 2005. After January 1, 2005, all operations will be secondary to co-channel interoperability communications. Analog FM emission shall exclusively be used for operation on the VHF and UHF interoperability channels.” 1 Therefore, since frequency 453.4625 MHz is secondary to co-channel interoperability communications, Franklin Square and Munson Fire District must discontinue operation on this frequency if the channel is needed for interoperability. We recognize that such discontinuation may hinder day- to-day operations on this channel to such an extent that Franklin Square and Munson Fire District may need to consider moving to another channel.
