Defining Radio Channels
Specifying the Frequency Control Functions
Each frequency may be assigned a label and a frequency control function to select the
transmitter, receiver, and monitor. The functions defined are used when the frequency
select keys are pressed from the console.
The Frequency Label (Label) is a 1- to 10-character name, which displays on the console
display when the frequency is selected. These labels are typically
F1
,
F2
, etc., but can be
any characters you want. For single frequency channels, the label is not referenced.
The Transmit Function (TX) is a tone or current signal used when the console Transmit
key is pressed. When the transmit key is released, the Receive Function is issued.
The Receive Function (RX) is a tone or current signal used to initialize the receiver
frequency when the system is started and when the receiver frequency is selected from the
console.
The Monitor Function (Mon.) is a tone or current signal used when the console
Monitor
key is pressed. When the monitor key is released, the Select Function is issued.
Move the mouse cursor over the TX, RX, or Mon. fields and click. A list of buttons
labeled with the available tone frequencies or DC currents appears. Click the desired
function.

Similar to the frequency control functions, the PL (private line) control functions are used
when the PL or CG (channel guard) keys are pressed.
The PL Label is a 1- to 7-character identifier displayed on the console when the PL is
selected. These labels are typically PL1 , PL2 , etc., but can be any three characters you
want. The PL Select Tone is a tone signal used when the console PL keys are pressed.
In the
PL
field, enter a value of
2
to
8
for the number of PL Select Tones desired. The PL
labels and Select Tone fields will appear.
