How to use Break-in?
While using the Digital Call Sign squelch (DSQL), the squelch never opens (no audio is heard) even if a
call is received, unless the call is addressed to your own call sign.
However, when a call including the “BK ON” signal (break-in call) is received, the squelch opens and
audio is heard even if the call is addressed to another station.
