Programming Memory Channels 113
T DCS - The CTCSS tone system is activated for transmission and the
Digital Coded Squelch system is activated for reception. Only signals with
the matching tone will open the squelch: your radio will remain silent
otherwise. With this option selected, the CTCSS and DCS columns become
active to set the CTCSS frequency to be transmitted and the DCS code to be
used for reception.
D Tone - The Digital Coded Squelch system is activated for transmission
and the CTCSS tone system is activated for reception. Only signals with the
matching tone will open the squelch: your radio will remain silent otherwise.
With this option selected, the RX CTCSS and DCS columns become active
to set the code to be used.
Split Tone - The CTCSS tone system is activated for both transmission
and reception. Only signals with the matching tone will open the squelch: your
radio will remain silent otherwise. With this option selected, both the CTCSS
and RX CTCSS columns become active to set the CTCSS frequencies to be
used. In this mode, the radio can use
different CTCSS frequencies for
transmission to the repeater and reception by the radio. The radio uses two
separate CTCSS frequencies for
transmission and reception .
CTCSS : Select one of 50 tone frequencies to be used in the Tone mode. This is the
sub-audible tone that will be transmitted for access to a repeater (i.e., you will not hear
it; but the repeater will). This field becomes active only when Tone is selected as the
Tone Mode.
RX CTCSS : Select one of 50 tone frequencies to be used in the Tone Sql mode. This
is the sub-audible tone that will be transmitted for access to a repeater and must be
received by your radio before it will hear an incoming signal. This field becomes active
only if Tone Mode is set to TSql.
Note: This is NOT the tone used for normal repeater access. Unless
the repeater is specially set up for this option (fire-rescue, emergency
services or commercial repeaters as examples), your radio will be
able to activate the repeater; but it will hear NOTHING back. You will
see an indication on your radio is receiving a signal; however, you
will hear nothing.
In this case, change your setting to Tone with the same value set in
the CTCSS column and try again.
DCS : Select one of 104 DTCS codes to be used in the DTCS mode. This is the code
associated with a 3-tone sub-audible sequence that will be transmitted for access to a
repeater and must be received by your radio before it will hear an incoming signal.
This field becomes active only if Tone Mode is set to DTCS.
