BK Radio
BUSY CHANNEL LOCKOUT
The Aurora radio has a Busy Channel
Lockout [BCL] feature that you can
use to program individual channels.
With the BCL feature, you can keep
anyone from hearing a channel unless
the correct Code Guard signal is
received.
With BCL set, the transmitter cannot
transmit until the channel is free of
activity. If the channel is active, the
transmitter cannot transmit until a
correct decode Code Guard is received.
If the BCL transmit criteria is not met,
you will hear a boop. When this
happens, release PTT and try
transmitting again.
If the BCL feature is set for a channel
and that channel has a Code Guard
assigned to it, the carrier must have a
tone. If a carrier is detected on that
channel and no tone is present, then the
radio will remain muted [no tone is the
wrong tone].
The BCL feature is activated
whenever you tune in to a channel that
has BCL assigned. If BCL mode is set
on the channel, the tone/monitor
feature will not override the BCL
function.
