CTCSS/DCS/EPCS OPERATION

DCS OPERATION

Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more advanced tone system which generally provides more immunity from false paging than does CTCSS. The DCS Encoder/Decoder is built into your VX-8R, and operation is very similar to that just described for CTCSS. Your repeater system may be configured for DCS. The DCS Squelch may be quite useful in Simplex operation if your friends use transceivers equipped with this advanced feature.

Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that you select a DCS code.

1.Press the key, then press the key. This provides a “Short-cut” to Set Mode Item 95: SQL TYPE.

2. Rotate the DIAL knob until “DCS” appears on the display; this activates the DCS Encoder/Decoder.

3.Press the key to save the new setting and exit to nor- mal operation.

4.Press the key, then press the key. This provides a

“Short-cut” to Set Mode Item 26: DCS CODE.

5.Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask the repeater owner/operator if you don’t know DCS Code; if you are working simplex, just set up the DCS Code to be the same as that used by your friends.

6.When you have made your selection, press the key to save the new settings and exit to normal operation.

Remember that the DCS is an
