Abstract :
A VHF Mobile Unit is described which is one third the weight and employs 35 per cent less tubes than conventional units. The equipment meets current Canadian and U. S. Specifications, is rated at 10 watts rf output and has a sensitivity under 0.5 mv. Compactness has been gained by the use of printed components, front-mounting and considerable simplification of the detection and modulation circuits. The frequency multiplication factor of the transmitter is 4, which considerably reduces the number of spurious emissions.
