DCS Operation
Another form of tone access control is Digital Code
Squelch, or DCS. It is a newer, more advanced tone sys-
tem which generally provides more immunity from false
paging than does CTCSS. The DCS Encoder/Decoder is
built into your VXA-700, and operation is very similar to
that just described for CTCSS. Your repeater system may
be configured for DCS; if not, it is frequently quite useful
in Simplex operation if your friend(s) use transceivers
equipped with this advanced feature.

Note: Remember that the DCS is an Encode/Decode sys-

DCS code is received on an incoming transmission. Switch
the DCS off when you’re just tuning around the band!
