Channel
0
is the station
tuning
channel.
The tuning channel is programmed
with
the optimum frequency for tuning the
RF
sections and conducting audio
tests
in
the station. The
tuning
channel frequency is determined
by averaging
the
highest
and lowest programmed channel frequencies.
The channel
0
transmit signal
consists of an audio signal encoded with
DPL
code
031.
The station should never
be
keyed over the air
while
channel 0 is selected.
The transmit frequency may not
be on an authorized channel.
