Abstract

The unit incorporates a transceiver, having a channel changing mechanism, and a radio, having a tuner, a tone control and a balance control, together with a volume control in a common housing having a front wall, for conjoint mounting of the unit in an automobile or the like. The front wall is formed with an opening therethrough adjacent one end thereof and with a slot therethrough adjacent the opposite end thereof. Coaxial shafts for the radio tuner, tone control and balance controls extend through the opening adjacent one end of the front wall, and have respective operating knobs secured to their outer ends whereby the radio controls are grouped adjacent the one end of the front wall. A volume control shaft is connected to the volume control, and a channel control shaft is connected to the channel changing mechanism. A tubular outer shaft extends through the slot and is connected by gears to the channel control shaft. An inner shaft extends coaxially through the tubular outer shaft and is connected, by a double universal joint, to the volume control shaft. Respective operating knobs are secured to the outer ends of the coaxial tubular and inner shafts, whereby the transceiver channel control and the volume control are conveniently grouped adjacent such opposite ends of the front wall. The coaxial tubular and inner shafts are adjustable, as a unit, along the slot to adapt to different mounting conditions, and the gears provide play for this adjustment.
