NAVTEX system operation

-   The world is divided into 16 areas (called Navareas) as shown at right.

-   Each Navarea has multiple NAVTEX stations and each NAVTEX station has an

identification code, from "A" to "Z".

-   The service range of a NAVTEX station is typically 200-400 nautical

miles depending on the terrain and station transmit power. A NAVTEX station

normally broadcasts every four hours.

-   There are two channels including international channel, 518 kHz, and

local channels, 490 and 4209.5 kHz. International channels broadcast

messages in English. On local channels, 490 kHz, is available in the UK,

France, etc., using their own languages. 4209.5 kHz is allocated for NAVTEX

broadcasts in tropical areas - not widely used at the moment.

Dual-channel NAVTEX Receiver

Enhances the navigation efficiency and safety by watching NAVTEX
messages broadcasted on both international and local channels

-   FURUNO NX-700 is a dual-channel NAVTEX receiver for SOLAS ships

complying with the new NAVTEX performance standard MSC.148(77) which is

implemented on and after 1 July 2005.

-   The NX-700 can receives two channels simultaneously. One is set for 518

kHz to receive international NAVTEX messages and another is selectable from

490 or 4209.5 kHz for domestic or local  NAVTEX messages. These messages

include a variety of safety information such as Navigational Warnings,

Meteorological Warnings, Search and Rescue (SAR) information and other

information for ships sailing within the reach of each service station°s

coverage. The broadcast station can be selected automatically according to

own ship position when the NX-700 is connected with a GPS navigator.
 

-   Every incoming message is stored in non-volatile memory and is 

displayed on the clear 5" silver bright LCD. Three different font  sizes are

available and one of them can be selected on menu.

-   The NX-700A consists of a receiver, display with printer and antenna

units. The NX-700B has a low profile, stylish display without a printer,

receiver and antenna units. The compact umbrella type antenna requires no

grounding because it is H-field antenna. In addition, the antenna

incorporates a high-performance preamp within the compact body, which gives

reliable and  uninterrupted reception without an extra whip antenna.
