<p>An FM reception device for FM radio (RF) signals which has a pilot tone (P) at a defined frequency. An interference detector (2) detects reception interference from the deviation of a pilot tone store (a) from a desired value (d), in which the pilot tone store (a) is the difference of the demodulated pilot tone (P) with a pilot tone reference frequency (19kHz), which is generated in the reception device (1) by at an oscillator set for the defined frequency.</p> |
