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 acti-
vated, if desired.
Whenever you push the PTT, or every 25 (or 15) seconds
after ARTS is activated, your radio will transmit a signal
which includes a (subaudible) DCS signal for about 1 sec-
ond. If the other radio is in range, the beeper will sound
IN RANGE
(if enabled) and the display will show " " as
OUT RANGE
opposed to the out of range display " " in
which ARTS operation begins.
Whether you talk or not, the polling every 15 or 25 sec-
onds 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 deacti-
vated (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
" OUT RANGE ." If you move back into range, your radio will again beep, and the display
IN RANGE
will change back to the " " indication.
