Due to the unique construction of its transmitter and heat sink, the RT2048 is able to operate with a continuous output power of 25 watts on all possible channels in the fre- quency range 154.40-163.75 MHz. The unit also offers a choice of 30 additional private channels or scan- ning facilities. The Sailor RT2048 is prepared for connection to 12V DC or 24V DC (by means of a Sailor N420 Power Supply). The set has an extremely low power consumption. In the standby mode, the power consump- tion is less than 0.1 a. The new compact state-of-the-art VHF is fully transistorized and equipped with a synthesizer and mi- croprocessor. Its compact cabinet houses both transmitter, receiver and a large, powerful 6-watt loud- speaker, which reproduces the sig- nal loudly and clearly—even at great distances. Furthermore, the built-in audio amplifier is capable of delivering an additional 6 watts into an external loudspeaker. And although the Sailor RT2048 is compact (height-104 mm; width- 228 mm; and depth-169 mm), it is easy to service, since the set consists of four easily replaceable modules. This high-quality, low-priced unit is easy to operate, even in bad weather, due to a button for contin- uous turnstyle operation of squelch and AF levels. All controls are easily accessible on the front plate with pushbutton keyboard, LED display and nighttime illumination. SPERRY MARINE Circle 26 on Reader Service Card Sperry Marine Inc., a subsidiary of Newport News Shipbuilding, was selected to supply the radar/ARPA, navigation workstation, global posi- tioning and gyrocompass systems for the Swedish icebreaker Oden II. The Oden II's radar/ARPA sys- tem is based on Sperry Marine's newly introduced RASCAR (Ras- terscan Collision Avoidance Radar). Four complete RASCAR systems (three X-Band and one S-Band), a fifth radar display and two slave monitors were supplied in a fully interswitched system. The RAS- CAR was selected primarily because its superior display picture quality and resolution were deemed abso- lutely vital for ice detection. All RASCAR displays will be con- trolled through a touchscreen mounted on the surface of the dis- play. The speed, accuracy and sim- plicity of this user/machine inter- face were also major considerations for the Oden II's complex radar sys- tem. Sperry will also supply a naviga- tion workstation based on its rug- gedized marine PC model MC 500. This computer recently received certification for cargo loading appli- cations from Det norske Veritas, Lloyd's, Germanische Lloyd and Bureau Veritas. The workstation will allow Oden II's bridge staff to digitize charts and develop voyage plans for display as overlays on the radar displays. When printed out on the flat bed plotter, hard copies of 54 Maritime Reporter/Engineering News netic headings, arrival alarms, an instant-position memory and a "sleep" mode to conserve battery power. Built-in manual dead-reckoning course computer, using speed head- ing set and drift information, pro- vides continuously updated posi- tions between satellite fixes. Drift speed and direction (Drift Set) can be entered manually or automatically computed using two successive satellite fixes. In auto- matic mode, drift data is automati- cally updated at each satellite fix. For automatic positioning be- tween fixes, an interface for flux gate compass, speed log and Loran- C receiver is optionally available. Interface for serial hard copy print- er is also available. SP RADIO Circle 22 on Reader Service Card S.P. Radio A/S has just intro- duced a new VHF radiotelephone for the marine industry called the Sailor RT2048. The VHF Sailor RT2048 is a sim- plex/semi-duplex station for ship- to-ship/ship-to-shore communica- tion. It is equipped with all 55 inter- national maritime VHF channels, U.S. channels, 10 private channels, scanning facilities, quick channel 16, dual watch, 25-watt output pow- er, and built-in seacall as an op- tion.
