Arts (Automatic Range Transpond System) - Yaesu VX-1R Manual

ARTS (Automatic Range Transpond
System)
The ARTS feature uses DCS signaling to keep two
parties informed as to when they are within commu-
nications range and when they are not. This can be
particularly useful in Search-and-Rescue or any other
situation where is important to stay in contact with
another station.
Both stations must set their DCS codes to the same
code number, and activate their ARTS feature using
the command appropriate for their radio. Alert ring-
ers may be activated, if desired.
Whenever you push the PTT, or every 15 seconds
after ARTS is activated, your radio transmits a
(subaudible) DCS signal for about 1 second. If the
other radio is in range, the beeper sounds (if enabled)
and I!J RlJG (in range) is displayed in place of
OU iRNG (out of range), with which ARTS operation
begins.
Whether you talk or not, the radios continue to poll
each other every 15 seconds while ARTS is activated.
You can also have your radio transmit your callsign
via CW every 10 minutes, to comply with identifica-
tion requirements.
If you move out of range for more than one minute
(four polls), your radio senses that no signal has been
received. Three beeps sound, and the display reverts
to OU
TF?,~JG.
If
you move back into range, your radio
again beeps, and the display changes back to
IN
RtJ[j.
During ARTS operation, your operating frequency is
not displayed, and you cannot change it or other
settings; you must first terminate ARTS to resume
normal operation. This is a safety feature to prevent
accidental loss of contact due to channel change, etc.
