The SAILOR RT4822 VHF DSC is specially suitable for the professional maritime business. The radio is an advanced DSC unit (class A) with all the necessary equipment built in to one compact unit and therefore ideal for areas with limited space as it is the case on most vessels. In a basic configuration the SAILOR RT4822 includes a transceiver unit and a handset. The SPARC-bus interface, an advanced balanced data and AF interface, can be used to interconnect multiple control units and for exterior computer based control/programming options. The maximum distance between transceiver unit and handset control unit maybe 40 m in 12V DC installations, in 24V DC installa- tions up to 80 m. The Sailor VHF radio combines transmitter, receiver and a 4W loudspeaker in one. The set is equipped with an audio amplifier capable of delivering an additional 6W into an external loudspeaker. The nominal system power supply is 12V DC. By means of SAILOR N163S and/or N420, the system can be powered from the AC mains or a 24V DC battery. A standard NMEA interface for connection to on-board navigational equipment is available in the transceiver option connector.
