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
Station B does not hear that
Station C is calling Station A
Station C calling to Station A with “BK OFF”
Station A
and B are
communicating
using the
Digital Call
Sign squelch
Station B also hears that
Station C is calling Station A
Station C calling to Station A with “BK ON”
