    摘要： A method comprises detecting whether or not a frequency modulation broadcast receiver is tuned to an overdeviated frequency modulated broadcast, or is at a location where overdeviated frequency modulated broadcasts exist or has received a user input indicating the presence of an overdeviated frequency modulated broadcast; and in response to the detection, automatically adjusting operation of the frequency modulated broadcast receiver. Automatically adjusting operation comprises adjusting one or more parameters or settings in such a way as to alter the susceptibility of a speaker arrangement to the possibility of being overdriven by overdeviated frequency modulated broadcasts.

    摘要： A squelch tail eliminator for use in a receiver having a continuous tone coded squelch system and provision for the disabling of the tone coded squelch system is disclosed. A pulse generator, responsive to the discontinuance of a given tone, generates a gating pulse that inhibits the disabling of the tone coded squelch system for the time duration of that pulse, providing squelch tail elimination at the end of a message transmission indicated by the discontinuance of the tone.
