How to use Break-in?
While using digital call sign squelch, the squelch never opens (no audio sounds) even if a call is received, unless
your own call sign (“MY”) is specified. (p. 93)
However, when a call including the “BK ON” signal (break-in call) is received, the squelch will open and audio
sounds even if the call is specified for another station.
