Abstract
A mobile radiotelephone having a power rating of 30 watts is described. The unit incorporates transmitter, receiver, operating controls and loudspeaker in a single compact aluminum alloy case. Total weight is less than twelve pounds. The unit is small enough for underdash mounting in a modern passenger car. The transistor power supply is in a separate case designed to be mounted on the vehicle firewall. Heater voltage regulation is employed to maximize vacuum tube reliability. Careful attention to thermal design has minimized the development of hot spots in the interior of the equipment.
