For digital TalkGroup+NAC squelch the user would have to select 't' in the initial (receive) screen
(in digital mode only), if so then the editor to change the value would appear as follows:
Figure 2-12. The digital TalkGroup squelch edit screen .
The editor works as follows:
to
enter number, cursor automatically advances. $=HEX Mode.
accept the entry and continue
abandon the entry and exit
The default edit mode is hexadecimal (HEX), four digits 0000 to FFFF, the dollar sign “$” is used to
indicate a HEX edit. The edit mode can be changed to decimal using command L3-3. In that case
the range would be 00000 to 65535.
As a squelch mode TalkGroup includes NAC for both receive and transmit so when you press
“ENTER” to continue the editor continues to the NAC editor (shown above). When you exit from
NAC, then if you were editing for receive you would return to the first screen, but the
Transmit/Receive indicator character (second last character on the line) has changed to a “T” to
indicate that you are editing for transmit. If you are finishing an edit of the transmit value, then the
values are written to memory and the editor exits.
For digital ID Call squelch (available for digital transmit only) the user would have to select 'i' in
the transmit screen, if so then the editor to change the value would appear as follows:
Figure 2-13. The digital ID Call squelch edit screen .
The editor works as follows:
to
Decimal mode: enter number, cursor automatically advances.
accept the entry and continue
abandon the entry and exit
The edit mode is decimal only seven digits 0000001 to 9999999.
As a squelch mode, ID Call exists for transmit only so when you press “ENTER” to continue the
values are written to memory and the editor exits.
2.2.4 ID Call Operation
As seen above, the transceiver can be configured, in digital mode, to use ID call as a selective
squelch method, in this mode the transmitting unit sets it's TalkGroup to zero (0), and transmits the
intended Unit ID number (decimal 0 to 9,999,999), upon seeing the '0' talkgroup, the receiver
ignores everything except the ID number.
Of course the receiver will have to be on the correct frequency and in digital mode.
