PERATION
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-5R
, 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 trans-
ceivers equipped with this advanced feature.
Just as in CTCSS operation, DCS requires that you set the Tone Mode to
DCS and that you select a tone code.

Press the
[F/W]
key, then immediately press the
[1(TN)FRQ]
key. This provides a
“short-cut” to Menu #29 (“
SQL TYPE
”).
‚
Rotate the DIAL until “
DCS
” appears in the upper right-hand area of the LCD; this
activates the DCS Encoder/Decoder.
ƒ
Now press the
[BAND(SET)AR]
key, and rotate the DIAL to select Menu #31 (“
DCS
SET
”).
„
Press the
[BAND(SET)AR]
key to enable adjustment of the DCS Code.
Rotate the
DIAL
to select the desired DCS Code (a three-digit number). Ask the re-
peater 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 friend(s).
†
When you have made your selection, press the
[2(CD)TAG]
key to save the new set-
tings and exit to normal operation.
Remember that the DCS is an Encode/Decode system, so your receiver will
remain muted until a matching DCS code is received on an incoming trans-
mission. Switch the DCS off when you’re just tuning around the band!
