The NX-300 receives NAVTEX messages and verifies the ID of received messages. It features two narrowband receivers, one tuned to the 518 kHz international Navtex frequency and the other to the 490 kHz domestic or local country frequency. Selection is made by a Frequency Select switch on the front panel.
NAVTEX is a worldwide coastal English language telex broadcast system. The broadcast stations transmit Navigational Warnings, Meteorological Warnings, Search and Rescue (SAR) information and other data for ships sailing within their service range. The service range is 200-400 nautical miles depending on the terrain and station transmit power; messages are broadcasted every 4 hours. The Navtex service on 490 kHz is available in the UK, France, etc., using their own languages. The NX-300 features multi-language processing.
Every incoming message is identified and new messages are read on the high-contrast 4.5″ silver bright LCD display; no paper is required. However, the message can be printed out via a PC interface. The broadcast station can be selected automatically according to own ship position when the NX-300 is connected with a GPS/DGPS navigator outputting position in NMEA 0183 format.
The NX-300 consists of a compact, waterproof display and an antenna unit. The waterproof display unit can be installed in the flybridge or at any convenient place on the vessel.
