Abstract

The unit incorporates a transceiver, having a channel changing mechanism, and a radio, having a radio tuner, enclosed in a common housing for conjoint mounting. A transceiver control shaft has an inner end in operative connection with the channel changing mechanism and an outer end having a first gear secured thereto. A tubular outer shaft extends through an opening in the front wall of the housing and has a second gear secured to its inner end. An inner shaft extends coaxially through the tubular shaft, and respective control knobs are secured to the outer ends of the tubular shaft and the inner shaft. A pair of levers have their inner ends interconnected by a pivot and their outer ends respectively pivoted on the transceiver control shaft and tubular shaft, and an idler gear is freely rotatable on the pivot and meshes with the first and second gears to constitute a driving connection therebetween. The tubular outer shaft extends through an elongated slot in the front wall of the housing, and the inner end of the inner shaft is connected by one or more universal joints to the radio tuner.
