TDFM-136B Operating Instructions
In Digital Mode
Monitor Mode 'm'
- digital receive only, non-selective. The receiver will open on any valid P25
signal. This is the default digital squelch mode.
Network Access Code (NAC) 'n'
– digital receive only, selective. The receiver will open on
any P25 compliant digital signal, having the correct NAC.
Tal NAC 'g'
– digital receive and transmit, selective. The receiver will open on any
P25 compliant digital signal, having the correct NAC, and the correct TalkGroup. For transmit it
indicates that the specified NAC and TalkGroup codes will be transmitted.
ID Call 'i'
– digital transmit only, selective. The transmitted signal will carry the ID of a specific
transceiver. Only a radio with that ID programmed as it's Unit Identification (UID) will be able
to receive the signal. Note that the UID can be set via command L5-9.
In Both Analog and Digital Modes
Transmit Disabled '-'
– valid for both analog and digital operating modes, transmit only. This
indicates that transmit is disabled for this memory. Pressing PTT will result in a display of
“Transit Disabled” on the screen.
Editing Squelch Modes
The
edit squelch mode
command is easily accessible, it is command L1-9. To access this
command, simply press '9', on the front panel keypad. Notice that the key is also marked “SQL”.
This command allows the user to edit the squelch mode of the selected channel & memory. Since
squelch mode is duplex, and the selective squelch options have values that can be edited as well,
this editor has more steps than most others. The general flow of the editor is as follows:
1.
Select receive Squelch mode (dependent on operating mode).
2.
If Squelch mode has a value then select the value(s)
3.
If simplex then done, else repeat for transmit.
All Squelch mode edits start the same way, the cursor appears at the Squelch mode character field
of the channel to be edited. The edit screen appears as follows:
Figure 2-6. The screen to edit the Main Squelch
Mode for receive.
You may now edit the Squelch Mode as follows:
step up/down through available squelch modes.
accept the entry and exit
abandon the entry and exit
Remember that the available squelch modes will be constrained by the operating mode as shown
in table 2-2 above.
