	NAVTEX
		NAVTEX is an international automated medium frequency (518 kHz) direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent marine safety information to ships.
		NAVTEX stations in the U.S. are operated by the U.S. Coast Guard.
		It is intended that all NAVTEX weather be broadcast with subject indicator "B", for Meteorological Warnings, which cannot be rejected by the NAVTEX receiver, or "E" for routine forecasts.

		NAVTEX is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent marine safety information to ships.
		NAVTEX stations in the U.S. are operated by the United States Coast Guard.
		NAVTEX broadcasts are primarily made on Medium frequencies of 490kHz and 518 kHz, using narrow-band direct printing (NBDP), 7-unit forward error correcting (FEC or, Mode B) transmission and the CCIR-476 character set.

	NAVTEX
		NAVTEX is an international automated direct printing service for the promulgation of Marine Safety Information (MSI) to ships at sea.
		Vessels obliged to carry NAVTEX equipment within the GMDSS regulations must have the receiver switched on and tuned to the 518 kHz frequency continuously, and if access to the new national frequency is required then a second receiver is required.
		NAVTEX services in English on 518 kHz are now available in all coastal waters of Europe and in many other parts of the world so that worldwide vessels have access to marine safety information in English via the medium of NAVTEX.

	NAVTEX reception
		NAVTEX is a system to deliver local weather reports and navigational warnings to ships operating in coastal areas.
		NAVTEX is broadcast worldwide on 518 kHz using a data mode called SITOR-B (amateur radio operators might recognise it as AMTOR).
		NAVTEX stations transmit on a four-hourly cycle, apart from urgent messages which are transmitted immediately.

	Navtex - what it is and how it works
		The NAVTEX system is designed to be used in GMDSS Sea Area A2, and is utilised mainly by those countries with relatively small areas of coastline and/or sea areas to cover.
		A NAVTEX receiver is normally a compact unit, with an integrated printer, display and keyboard.
		NAVTEX receivers are supplied with their own antenna system, which is normally a short whip type antenna and a pre-amplifier.

		Navtex is part of the Global Maritime Distress and Safety System (GMDSS) that the International Maritime Organization (IMO) has been developing and regulating into existence over the last few decades.
		Navtex is the main source of Marine Safety Information (dubbed MSI, sorry) to vessels within a 200-mile coastal zone, using two medium-wave frequencies.
		There are stand-alone Navtex units that simply print out the text on a cash register-style roll of paper and PC programs that demodulate it from SSB or Ham radios to screen.

	Fitting a Navtex Receiver
		However, you can throttle down a Navtex receiver to only copy the segments of a broadcast you want to receive, to only copy the stations relevant to your location, and it will automatically avoid displaying duplicate text messages on its own.
		We left the U.S. believing that a Navtex receiver was probably a good idea, that we’d make our SSB/laptop system work in the short-term, and that we’d form a final conclusion about whether a dedicated receiver was worth its keep once we cruised here a while.
		Having a Navtex receiver aboard would have been useful to us when still a few days out of Bermuda, again when dealing with persistent head winds as we approached the Azores, and yet again when approaching Falmouth at the same time a forecasted Low was scheduled to arrive in the Channel.

	About Navtex
		NAVTEX provides much information but, for most of us yachtsmen and women, the weather is probably the most important.
		As NAVTEX wavelengths are so long, the ratio of height to wavelength is so insignificant as to negate any gain normally associated with antenna height.
		NAVTEX is old technology with data speeds that are akin to the tortoise compared to the hare of modern computer to computer links that sustain the Internet.

	PRACTICAL INSTRUCTION FOR USING THE NAVTEX RECEIVER ON BOARD
		The NAVTEX receiver is a valuable instrument that is able to receive written and automatic information concerning Maritime Safety (Radio warnings, Meteorological reports and distress alert transmissions), which is transmitted by the NAVTEX coastal services that have a determined service area of a range of up to 400 nautical miles.
		However, for a NAVTEX receiver to function adequately on board a vessel which has this system incorporated, proper knowledge of how to programme it, is vital.
		This practical advice will help ensure the efficient use of your NAVTEX receiver, guaranteeing the reception of maritime safety information within the respective areas of NAVTEX transmition station coverage, whose estimated range is up to 400 nautical miles from the transmitting antenna on land, and therefore, providing you with a safe voyage.

	What the Heck is Navtex? - Electronics - November 2003 - Power & Motoryacht - 1103electronics (Site not responding. Last check: 2007-10-26)
		I was pushing Navtex reception limits with the antenna just out in my tree-lined yard, inland of the hilly Maine coast and well over 100 miles from the Boston and Bay of Fundy broadcast facilities.
		So right there is one Navtex advantage: You should be able to get it on trips beyond the reach of even our powerful VHF weather network, say perhaps on a spring ride north in the Gulf Stream.
		ICS realized that since the Navtex messages only need to be viewed occasionally, the unit’s fine screen could also double as a repeater for NMEA data from instruments, plotters, etc. I’m a strong believer in offloading numerical data from precious color chart displays, and the Nav6plus does a fine job of it.

	Yachting and Boating World: NAVTEX
		For a start the majority of Navtex is transmitted at the bottom end of the MF band (490kHz and 512kHz), which is hardly "short wave band".
		There is a third Navtex frequency which is short wave at 4209.5kHz but I have yet to receive a strong enough signal to decode from any source.
		However, not having a Navtex receiver with a printer, I do use PC Navtex reception for storing navigation warnings which are relevant to my sailing area, having already read them on my dedicated Navtex receiver display.
