Abstract: 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.
