Mobile and fixed radio relay operation in the power radio service

The purpose of this paper is to describe various types and combinations of radio relay schemes, and the conditions under which they may be authorized for operation in the power radio service. Federal Communications Commission definitions and rules applicable to relay station operations are given in the appendix. A relay station is used to extend the range of communication between a radio station and the point with which it is desired to communicate. It may be necessary to install a radio station many miles from the office headquarters in order to obtain the desired radio coverage of the operating area of the power system, or to utilize a natural vantage point such as a hill or mountain.
