5.17.7 CHANNEL PARAMETERS
NOTE: If “ENTER PSWD” is briefly displayed when
attempting to select a parameter, see Section 5.17.3.
The “CHAN PARMS” menu parameter selects
the following conventional channel parameters that
can be reprogrammed. Press F2 switch to select the
“CHAN PARMS” parameter and then press the
Up/Down switch to display the desired parameter.
Then press the F2 switch to select it. The squelch
control parameters are unique to the type of conven-
tional channel selected (analog or Project 25).
RX FREQ - Programs the receive channel frequency.
The digit being changed flashes, and press the Up/
Down switch to select the desired number for that
digit. Then press the F2 switch to move to the next
digit. If an invalid frequency is entered, a beep sounds,
“INVALID” is briefly displayed, and the number must
be re-entered.
TX FREQ - Programs the transmit frequency the
same as the preceding RX FREQ.
CTCSS/DCS Squelch Control (Analog Channel)
RX CODE - Programs the receive Call Guard
(CTCSS/DCS) code. The currently selected code
and is initially displayed. Press the Up/Down
switch to select the desired code type (CTCSS
analog or DCS digital Call Guard). Then press F2
to select it and enter the code number similar to
programming a channel frequency as just
described.
TX CODE - Selects the transmit codes the same as
RX CODE above.
NAC Squelch Control (Project 25 Channel)
RX NAC - Programs the Network Access Code
(NAC) which can be any number from 0-4095. The
procedure is similar to programming a RX FREQ
just described. If an invalid code is entered, a beep
sounds, “INVALID” is briefly displayed, and the
code must be re-entered.
TX NAC - Selects the transmit NAC the same as
RX NAC above.
TX POWER - Selects the desired power output level.
Press the Up/Down switch to scroll through the
following choices. When the desired setting is
displayed, store it by pressing the F2 switch.
•
POWER HI - High transmit power
•
POWER LO - Low transmit power
•
POWER SW - Switchable power selectable by
the High/Low power switch. This choice is not
available if that switch is not programmed.
TX TIMER - Enables or disables the time-out timer
on the current channel. Press the Up/Down switch to
select the on and off mode, and when the desired
setting is displayed, store it by pressing the F2 switch.
CHAN SPC (Analog Only) - Selects either wide or
narrow band channel spacing. Press the Up/Down
switch to select “WIDE” or “NARROW”, and when
the desired setting is displayed, store it by pressing the
F2 switch.
SQ ADJ (Analog Only) - 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.
