2.19 FRONT PANEL PROGRAMMING (FPP) MODE (Bands 1 – 4)
One of the bands may have the capability to program channel information such as
frequencies, PL tones, modulation types, etc from the front panel. ‘FPP’ will show up as one
of the soft menu items at the bottom of the screen if this option has been ordered. When
the FPP soft key is pressed, you will be prompted for channel information. Wait until the
cursor is flashing then press ‘OK’ for the next input or press ‘QUIT’ to finish and get out of
the programming mode. All changes up to that point will be saved. The prompts are as
follows:
TX Frequency
Enter the desired transmit frequency using the numeric key pad. If the
frequency entered is not within band limits or not on proper channel
spacing, the frequency will automatically be changed to the closest
valid channel.
RX Frequency
Enter the desired receive frequency.
TX PL
Enter the desired transmit PL tone frequency. After the last digit is
pressed the radio will verify that it is a valid frequency and flash the
first cursor again. Press ‘OK’ at this time. The transceiver supports all
standard PL tones. (Also known as CTCSS tones) TXPL tones are
generally used to open repeaters or in talk groups where the receivers
are squelch protected by PL tones. Enter ‘000.0’ for no tone. PL tones
are used by analog mode only.
RX PL
Enter the desired receive PL tone frequency. Enter ‘000.0’ no tone –
carrier squelch operation.
TX DPL
Enter the desired DPL code. You can not have both a PL and a DPL at
the same time. The one that is entered last will turn the other off. A
DPL of 000 means off. DPL codes are also known as DCS codes.
RX DPL
Enter the receive DPL code as above.
TX NAC
Enter the desired transmit P25 NAC code if using digital, otherwise just
press ‘OK’. The code is hexadecimal therefore the letters A to F could
also be used. Press the ‘A-F’ soft key to use buttons 1-6 as A-F. A
NAC or Network Access Code is used like PL tones but are only used
by P25 (digital) mode. A value of 293 is considered to be the standard
code for open channel.
RX NAC
Enter the desired receive P25 NAC code as above.
RX TYPE
Select the receive mode using the UP and DN keys – Analog, digital or
mixed. The mixed mode will allow the receiver to decode analog and
P25 digital signals as needed.
TX TYPE
This prompt will only come up if you selected mixed for RX. Select
analog or digital.
BANDWIDTH
Select 12.5, 20.0 or 25.0 kHz using the UP and DN keys. Bandwidth
may also be called ‘Channel Spacing’.
CHANNEL NAME
Use the UP and DN keys to scroll to the desired letter and press the
NXT soft key to get to the next character. Press ‘OK’ when done.
There will be a delay while the channel is saved, then the display will
return to normal.
