This report presents system objectives and design criteria for an in-mine ultralow frequency radio paging system. Coding formats, frequency, and bandwidth selection criteria leading to the system design are discussed. The prototype call alert transmitter and pocket page receiver is functionally described. The report includes circuit descriptions, schematics, parts lists, printed circuit fabrication, and assembly drawings. The report concludes with an estimate of the manufacturing cost for each assembly.
