ABSTRACT:
A tuning control for an aircraft radio apparatus is disclosed for a variety of applications wherein a single control provides a coarse tuning increment and, having the direction of movement of the control sensed, changes to a finer tuning increment as a function of changes in the direction of rotation of the tuning knob. The control frequency will change by twice the smallest frequency interval for each switch detent, until the direction of a knob rotation is opposite to that of the previous rotation. At that point the frequency will change by the smallest interval for the first detent position and thereafter to the next even interval for subsequent rotations in the same direction. This allows a single knob to be capable of providing both a rapid traverse over the spectrum of use, and still provide ready access to the smallest intervals of the spectrum.
