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 FT-8900, 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.

The ARTS feature uses DCS signaling to inform both parties when you and another
ARTS-equipped station are within communications range. This may be particularly
useful during Search-and Rescue situations, where is important to stay in contact with
other members of your group.
Both stations must set up their DCS codes to the same code number, then activate their
ARTS feature using the command appropriate for their radio. Alert ringers may be
activated, if desired.
Whenever you push the PTT switch, or every 25 seconds after ARTS is activated, your
radio will transmit a signal which includes a (subaudible) DCS signal for about 1 second.
If the other radio is in range, the beeper will sound (if enabled) and the display will
show “INRNG” as opposed to the out of range display “OUTRNG” in which ARTS
operation begins.
Whether you talk or not, the polling every 25 seconds will continue until you de-activate
ARTS. Every 10 minutes, moreover, you can have your radio transmit your callsign via
CW, so as to comply with identification requirements. When ARTS is de-activated, DCS
will also be deactivated (if you were not using it previously in non-ARTS operation).
If you move out of range for more than one minute (four pollings), your radio will sense
that no signal has been received, three beeps will sound, and the display will revert to
“OUTRNG.” If you move back into range, your radio will again beep, and the display

DCS Code Inversion
DCS Code InversionDCS Code Inversion
DCS Code Inversion
The DCS system was first introduced in the commercial LMR (Land Mobile Radio)
service, where it is now in widespread use. DCS is sometime referred to by its different
proprietary names, such as DPL® (Digital Private Line®, registered trademark of
motorola, Inc.).
DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data
rate of 134.4 bps (bit/sec). Occasionally, signal
inversion
can result in the
complement
of
a code to be sent or received. This prevent receiver squelch from opening with DCS
enabled, as the decoded bit sequence would not match that selected for operation.
Typical situations that might cause inversion to occur are:
Connection of an external receiver preamplifier.
Operating through a repeater.
Connection of an external linear amplifier.
Note that code inversion does
not
mean that any of the above listed equipment is
detective !
In certain amplifier configurations, the output signal (phase) is inverted from the input.
Small signal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification
stages may result in inversion of a transmitted or received DCS code.
While under most circumstances this should not occur (amplifier designs and industry
standards take this into account), if you find that your receiver squelch does not open
when both you and the other station are using a common DCS code, you or the other
station (
but not both
