CTCSS Decoder Diagram
Connect the TS-64WDS CTCSS Encoder/Decoder assembly to the CAT-800 as described in Figure 6-5.
The decoder must be connected to discriminator audio. Speaker or volume control audio will have
insufficient low frequency CTCSS tone content.

If you only want to send a CTCSS tone on the transmitter’s output when a signal is present on the
repeater’s input connect the CAT
-800 PTT #1 direct ly to the repeater’s PTT input. Connect the CAT -
800’s switch #5 (J1 - 7) to the TS64WDS’s pin #8 ORANGE/WHITE wire. Program switch #5 to follow the
COR input with the (*3954) command. Make sure Zone 6 Channel 5 is enabled.
If you only want to send a CTCS
S tone on the transmitter’s output whenever PTT #1 is active connect
the CAT- 800 PTT #1 directly to the repeater’s PTT input. Connect the CAT - 800’s switch #5 (J1 -7) to the
TS64WDS’s pin #8 ORANGE/WHITE wire. Program switch #5 to follow the PTT output wit h the (*3953)
command. Make sure Zone 6 Channel 5 is enabled.
If you want to continuously transmit a CTCSS tone without the ability to remote control it, connect the
CAT-800 PTT #1 (J1-
10) to pin #8 of the TS64WDS’s ORANGE/WHITE wire. Connect the TS64’s pin
#10 YELLOW/BLACK wire to the transmitter’s PTT input.
