Abstract

A radio receiver receives different signals by two tuners simultaneously. The two tuners may be a tuner for sound and a tuner for traffic information. Each tuner is provided with a local oscillator. When the receiving frequency of one tuner interferes with the receiving frequency of the other tuner, the receiving frequency of any one tuner is altered to a frequency not causing interference. Consequently, both tuners can receive signals with high quality.
