Tx Inhibit On Busy
RSS LOCATION
DEFINITION Disables transmit while carrier is present on channel (channel is busy). A busy
tone will be heard when the PTT is pressed.
DEFAULT/CHOICES Default: N
Choices: ■ Y ■ N
DEPENDENCIES Receive squelch type is equal to carrier squelch.
EXCEPTIONS Does not apply when receive squelch type is not equal to carrier squelch, there-
fore it is not compatible with Busy Channel Lockout.
RECOMMENDATIONS Use when channel is shared by several users. Prevents accidentally transmitting
on top of other users. Pressing PTT when a carrier is present causes the radio to
generate a busy tone. Compatible with RapidCall signalling and scan.

culties when talking through repeater systems.
