• MEMORANDUM June 30, 1981 TO: J. R. Hudgens FROM: J. W. Crate SUBJECT: Justification, Purchase of Motorola Base Station Present plans are to convert the Public Works Department to a repeater system with voting receivers. This .will allow increased talk-in range for the portable radios. This system would then be identical to the Police and Fire systems. The major components of this type system are two receivers, one transmitter, and the voting comparator. In operation the voting comparator samples audio from the two receivers and sends the best signal to the dispatch console and also the repeater transmitter for retransmission to all other mobile units. The City already owns a comparator which we plan to use in this system. This comparator was included at no cost with equipment purchased-for the Police Microwave system. This compara- . tor.is valued at approximately $2,000.00. By purchasing a Motorola base station with proper options, this comparator may be used in conjunction with the base receiver to form 2/3 of the voting receiver system when converting to a repeater. This will save the City $2,000.00 for the comparator and $1,400.00 for one receiver. This equipment could not be utilized with other vendors' base station and additional equipment would have to be purchased. Therefore, this is a single source item. In addition to the initial savings, the City also has ap- proximately $1,800.00 in spare parts for the existing Motorola base stations and comparators. These parts could be used to speed service and shorten downtime on this equipment. By purchasing a Motorola base station, the City will continue to enjoy single vendor responsibility at the base station site. This is very advantageous when interference problems occur be- tween base stations. Motorola guarantees 24 hour service for base stations and repeaters. This is a big plus in critical applications such as this. J. W. Crate
