Radio having adjustable seek sensitivity based on average signal strength and method therefor
First Claim
1. A tuneable radio having an adjustable seek sensitivity, said radio comprising:
- a radio receiver for receiving broadcast radio wave signals;
a tuner adjustable for selecting from a plurality of radio wave signal channels;
a signal detector for detecting signal strength of the received radio wave signals;
a seek input for initiating a seek operation to seek a radio wave signal channel having a detected signal strength greater than a seek sensitivity threshold; and
a controller determining an average value of the detected signal strength of the received radio wave signals that exceed a minimum signal strength level, said controller adjusting said seek sensitivity threshold based on said average value.

Abstract
A tuneable radio and method for automatically adjusting the seek sensitivity alignment for seek operations. The radio has a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting from a plurality of radio wave signal channels. A detector detects signal strength of the received radio wave signals, and a seek input allows a user to initiate a seek operation to select a signal channel having a signal strength exceeding a seek sensitivity threshold. A controller calculates an average signal value and adjusts the seek sensitivity threshold based on the average value. The controller adjusts the seek sensitivity when it is determined that the radio has travelled beyond a minimum distance.
