Split Tone Operation

The FT-857 can be configured in a "Split Tone" configuration via the Menu mode.
This allows you to encode a CTCSS Tone but decode a DCS code, encode and decode
different CTCSS Tones, encode (only) a DCS code, etc.
1. Press and hold in the [ FUNC ] key for one second to enter the Menu mode.
2. Rotate the SELECT knob to recall Menu Mode No-001 [ EXT MENU ] , then rotate the
DIAL to change the setting to "ON" to enable the extended Menu Mode.
3. Rotate the SELECT knob to select Menu Mode No-079 [ SPLIT TONE ] .
4. Rotate the DIAL knob to select "ON" (to enable the Split Tone feature).
5. Press and hold in the [ FUNC ] key for one second to save the new setting and exit to
normal operation.
When the Split Tone feature is activated, the Multi Function Row "e" selection changes to
[ ENC, DEC, TDCH ] . So, you can set the desired encoder (by pressing [ A ]( ENC ) key, repeat-
edly, if necessary) and decoder (by pressing the [ B ]( DEC ) key) separately.
When the Split Tone feature is activated, you can see the following additional parameters.
T-T: Encodes a CTCSS Tone and Decodes a CTCSS Tone
T-D: Encodes a CTCSS Tone and Decodes a DCS Code
T:
CTCSS Tone Encode only
D: DCS Encode only
D-T: Encodes a DCS Code and Decodes a CTCSS Tone
D-D: Encodes a DCS Code and Decodes a DCS Code
D-D: DCS Decode only
D-T: CTCSS Tone Decode only
Split Tone Frequency or DCS Code Setup
1. Press and hold in the [ A ]( ENC ) (if you use CTCSS) or [ B ]( DEC ) (if you use DCS) key
for one second. This instantly recalls Menu Mode No-083 [ TONE FREQ ] or No-033
[ DCS CODE ] .
2. Press the SELECT knob momentarily, then rotate the DIAL knob to select the "R" op-
tion. This is the tone you Receive, i.e. the "Decode" tone.
3. Press the SELECT knob momentarily, then rotate the DIAL knob to select the desired
Decode CTCSS frequency (or DCS code).
4. Press the SELECT knob momentarily, then rotate the DIAL knob to select the "T" op-
tion. This is the tone you Transmit, i.e. the "Encode" tone.
5. Press the SELECT knob momentarily, then rotate the DIAL knob to select the desired
Encode CTCSS frequency (or DCS code).
6. Press and hold in the [ FUNC ] key for one second to save the new setting and exit to
normal operation.
