Abstract
Mechanically tuned radios and related methods are disclosed that utilize ratiometric time measurements to detect settings for mechanical adjustment mechanisms. The radio systems and methods disclosed make a first time measurement associated with a mechanically adjusted circuit, make a second time measurement associated with the mechanically adjusted circuit, determine a setting for the mechanical adjustment mechanism based upon a ratio associated with the first and second time measurements, and utilize the setting to select a tuning frequency for signals received by the radio. More generally, ratiometric time measurements can be used to determine a setting for a mechanical adjustment mechanism for a mechanically adjusted circuit, and this setting can be used to at least part control a desired operational feature of a device.
