Squelch Fine Tune (SQL)

This menu-selection allows the radio-user to select (and adjust) how much carrier energy is required in order for the radio's speaker to unmute. When a higher value is selected by the radio-user, a stronger carrier signal is then required for the radio's carrier threshold to be reached and for the radio's speaker to unmute; this helps to reduce interference and unwanted noise. This feature applies while operating in Conventional communications mode.
