The ARTS TM feature uses DCS signaling to inform both parties when you and another
ARTS
TM
-equipped station are within communications range. This may be particularly
useful during Search-and Rescue situations, where it 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
TM feature using the command appropriate for their radio. Alert ringers may be
activated, if desired.
Whenever you push the PTT , or every 25 (or 15) seconds after
ARTS TM 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 “
IN RANGE ” as opposed to the out of
range display “ OUT RANGE ” in which ARTS TM operation be-
gins.
Whether you talk or not, the polling every 15 or 25 seconds will
continue until you de-activate ARTS
TM . Every 10 minutes, moreover, you can have your
radio transmit your callsign via CW, to comply with identification requirements. When
ARTS
TM is de-activated, DCS will also be deactivated (if you were not using it previously
in non-ARTS TM 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
“
OUT RANGE
.” If you move back into range, your radio will again beep, and the display
will change back to the “
IN RANGE
” indication.
During ARTS
TM
operation, your operating frequency will continue to be displayed, but no
changes may be made to it or other settings; you must terminate ARTS TM in order to
resume normal operation. This is a safety feature designed to prevent accidental loss of
contact due to channel change, etc.
