5.14.6 Channel Parameters
The “CHAN PARMS” menu parameter selects the following conventional channel
parameters that can be reprogrammed. Press Select switch to select the “CHAN PARMS”
parameter and then rotate that switch to display the desired parameter. Then press the
Select switch again to select it. The squelch control parameters are unique to the type of
conventional channel selected (analog or Project 25).
Note
If “PASSWORD” is briefly displayed when attempting to select a parameter, see
Section 5.14.2.
Note If a mixed mode channel is selected, both the Rx Code (analog) and Rx NAC (P25) which
follow can be programmed. In addition, if the Tx Type is Analog, a Tx Code is
programmed, and if it is Digital (P25), a Tx NAC is programmed.
RX FREQ - Programs the receive channel frequency. To select the digit to change or
move the cursor to the right, press the Select switch. Then to display the desired digit,
rotate the Select switch. The frequency is stored after programming the last digit. If an
invalid frequency is entered, a beep sounds, “INVALID” is briefly displayed, and the
frequency editing mode continues to be selected.
TX FREQ - Selects the transmit frequency the same the preceding RX FREQ.
CTCSS/DCS Squelch Control (Analog Channel) - Changes the preset squelch setting
on that channel. The default setting is “0” and values of –7 to +7 can be selected.
Increasing this setting 7 causes the squelch to open sooner so that weaker
signals can be received, and decreasing it toward –7 causes the opposite to occur.
RX CODE - Sets the receive Call Guard (CTCSS/DCS) code. The currently selected
code is initially displayed. If required, rotate and press the Select switch to select the
desired code type (CTCSS analog or DCS digital). If an invalid code is entered, a beep
sounds, “INVALID” is briefly displayed, and the editing mode continues to be selected.
TX CODE - Selects the transmit codes the same as RX CODE above.
NAC Squelch Control (Project 25 Channel).
