Busy Channel Lockout
RSS LOCATION
DEFINITION
Limits audible conversations from other user groups and reduces transmissions
on top of other user groups.
DEFAULT/CHOICES Default: N

DEPENDENCIES
Receive squelch type not equal to carrier squelch.
EXCEPTIONS
Does not apply when receive squelch type is equal to carrier squelch, therefore it
is incompatible with Tx Inhibit on Busy.
RECOMMENDATIONS
Use when you don't want to hear anybody else's conversations, or when you
don't want one user group “eavesdropping” on another. Compatible with Rapid-
call signalling and scan.
WARNINGS
Not compatible with carrier squelch channels. May cause operational difficulties
when talking through community repeaters. Operation is less reliable when used
with Channel Scan, since it is more probable that you will key up on another
group.
IMPORTANT NOTE
If you press PTT on radio while there is a carrier on the channel, the radio follows
this protocol:
a. If the carrier has your TPL/DPL, then you are allowed to transmit just like nor-
mal
b. If the carrier has no TPL/DPL or the wrong TPL/DPL, then you will hear a
busy tone while you hold PTT. Release PTT and try again later.
A short carrier ‘break’ is required to return to the BCL protected state.
