How to use Break-in?
While using digital call sign squelch, the squelch never opens (no audio is heard) even if a call is received, unless
your own call sign is specified.
However, when a call including the “BK ON” signal (break-in call) is received, the squelch will open and audio is
heard even if the call is specified for another station.
Station B never hears that
Station C is calling Station A.
