The most typical Police Cruiser prewar model other than the P-69-12. No new Police Cruiser models had been launched after the War, though not less than the P69-18 was obtainable from present inventory through about 1951. The FCC issued an order after WWII directing that all new license purposes for land mobile radio companies had been to be issued a hundred and fifty MHz allocations, absent a compelling motive requiring low band or medium wave frequencies. They need to tune up to no less than fifty three MHz with out modification, but bear in mind that the tuning of the noise blanker can affect this and a receiver with poor sensitivity may be this manner as a result of the noise blanker is about too close to the channel frequency. The SP-2 is already wired this way and was primarily meant to facilitate the addition of a transmitter to the cell set up and placement of the receiver in the vehicle trunk compartment. This had the drawback that in cases where the receiver was a low frequency sort, full duplex operation was not attainable.

The widespread success of VHF FM in armored models throughout the warfare proved its superiority in cellular operation, and the males who would return from war to work in and design cellular radio systems had learned its benefits. The MRTI is a generic identify for a line of Mobile Radio Telephone Interconnect units that was made for Motorola by one other firm - they have been essentially a business autopatch unit.

It isn't supposed as an all-inclusive historical past of early land cell radio nor of the Motorola Corporation itself. The Deluxe line went by way of quite a few enhancements, which will probably be detailed in a separate net web page protecting Motorola postwar and 1950's tools. It was not uncommon to seek out Motorola receivers or transmitters matched up with competitive makes of equipment. Particularly aggravating for the collector and historian is that no P-69 mannequin numbers seem clearly or recurrently on the gear other than an obvious two digit quantity stamped on the lower housing shell, which was easily separated from the receiver, and on the paper tag which is glued inside the lid to indicate parts layout. The antenna input was designed for either a conventional broadcast whip or a copper "display" antenna contained in the automotive's headliner ("tarred fabric roof" sedans), except for the P-69-17 "UHF" receiver, which shared the transmitting "whip" antenna on the car's rear quarter panel and thus required a separate T/R relay field assembly.
