transmission and reception..
Select the tone frequency from those in the list. The value must be in
the list. The radio uses the one frequency set in the CTCSS Tone
column for both Encode and Decode (transmission and reception)
The values that appear in the RX CTCSS, DCS, and RX DCS
columns are ignored by the radio.
DCS - Digital Coded Squelch mode is activated for transmission and
reception using one DCS code for both. This mode is used in many
commercial systems.
When this option is selected, the DCS column becomes available.
Select the code from those in the list. The value must be in the list.
The radio uses the DCS Code for both transmissions and
reception.
The values that appear in the CTCSS, Rx CTCSS and Rx DCS
columns are ignored by the radio.
Bell - adds an alert ringer to CTCSS tone squelch operation, for added
convenience.
CTCSS Tone: Select one of 50 tone frequencies to be used in the Encode and
Decode modes. This value is set independently for each memory channel and will be
used by the radio for both reception and transmission if the channel does not have an
operating mode of "Split". This field is active only if the Tone Mode is set a mode that
uses a CTCSS tone. A value that appears in this field is ignored if one of the tone
modes that uses CTCSS is not activated.
DCS Code: Select one of the 104 codes available for use when the radio is in DCS
mode. This value is set independently for each memory channel. This field is active only
when a Tone Mode for DCS is selected. A value that appears in this field is ignored if
one of the tone modes that uses DCS is not activated.
Skip: Marks selected memory channel to be skipped during scanning. These
channels remain available for manual selection by turning the knob.
Off - indicates that the channel will be scanned for activity whenever scanning
is done.
Skip - indicates that the channel will be skipped.
