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 intended for another station.
Station B never hears that Station C
is calling Station A.
• Station C calls to Station A with “BK OFF”
Station A and
B are commu-
nicating us-
ing digital call
sign squelch.
Station B also hears that Station C
is calling Station A.
• Station C calls to Station A with “BK ON”
Station A and
B are commu-
nicating us-
ing digital call
sign squelch.
