ARTSYaesu FT-8900R Operating Manual Expanded Edition (courtesy of W5JCK) Page 50 of 77ARTSOverviewThe ARTS (Auto Range Transponder System) feature uses DCS signaling to inform bothparties when you and another ARTS equipped station are within communications range. Thismay be particularly useful during Search-and-Rescue situations, where it is important to stayin contact with other members of your group.Both stations must set up their DCS codes to the same code number, then activate their ARTSfeature using the command appropriate for their radio. Alert ringers may be activated, ifdesired.Whenever you push the PTT switch, or every 25 seconds after ARTS is activated, your radiowill transmit a signal which includes a (subaudible) DCS signal for about one second. If theother radio is in range, the beeper will sound (if enabled) and the display will show IN.RNG asopposed to the out of range display OUT.RNG in which ARTS operation begins.Whether you talk or not, the polling every 25 seconds will continue until you de-activateARTS. 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 alsobe 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 thatno signal has been received, three beeps will sound, and the display will revert to OUT.RNG. Ifyou move back into range, your radio will again beep, and the display will change back to theIN.RNG indication.During ARTS operation, it is not possible to change the operating frequency or other settingson the Main band; you must terminate ARTS in order to resume normal operation. This is asafety feature designed to prevent accidental loss of contact due to channel change.Set Up/Operate ARTSTo activate ARTS:1.
