Turkey invades Cyprus by Navtex - 20 October 2014

Navtex may not be the most obvious choice for declaring to the world that you are effectively annexing part of a country's waters, but this is the medium Turkey has chosen to claim part of Cyprus' Exclusive Economic Zone.

On 17th October 2014, Turkey's NAVTEX transmissions included a statement that part of Cyprus' EEZ was "reserved" by Turkey - an area where ENI-KIGAS have been carrying out exploratory drilling for offshore gas. Turkey is intending to move its own research vessel into the area, to carry out seismic surveys from 20th October to 30th December.

New Sailor 6391 NAVTEX unit - 01 November 2013

Cobham are launching the new Sailor 6391 SOLAS spec NAVTEX receiver. This is a triple band receiver with a separate touch screen display unit, which can also be linked to other Sailor systems such as their AIS.

Changes in US Forecast Coverage - 03 April 2012

Effective Apr 03, 2012 at 1800 UTC the US NAVTEX forecasts were reconfigured to limit coverage to within 200 nm of the coasts assigned to New Orleans, Miami and San Juan transmitters. Specifically, the forecast area for the New Orleans transmitter will cover the northern Gulf of Mexico from the Suwanee River, FL to the mouth of the Rio Grande, out 200 nm. The Miami NAVTEX forecast area will cover the waters around the peninsula of Florida from Suwanee River on the Gulf Coast, to Flagler Beach on the Atlantic Coast, out 200 nm. The San Juan forecast area will cover the waters within 200 nm of the San Juan transmitter, to include the Mona Passage and part of the Anegada Passage. This reconfiguration will better conform to the range of the transmitters, provide more detailed information along the immediate coast, and better meet broadcast time constraints.

India plans NAVTEX upgrade - 26 January 2012

The Indian Ministry Of Shipping have asked for tenders for the provision of establishment of a national NAVTEX network along the Indian coast line.

India already has some coverage with NAVTEX transmitters at Chennai and Bombay, but perhaps they are now looking to extend the coverage?

ICS wins BEEA Award - 14 October 2011

Congratulations to Kevin Page and the team at ICS Electronics on winning the British Engineering Excellence Award.

ICS produced a range of NAVTEX receivers as well as providing NAVTEX base stations and producing other radio communications based equipment. On being bought by McMurdo, the NAVTEX receivers were sold under the McMurdo name, and ICS concentrated on the base stations, and so disappeared from most people's view. With the changes in ownership of McMurdo, they have since bought themselves out, and have restarted producing the NAV-6 and NAV-6 plus receivers.

Improved NAVTEX Coverage on West Coast of Scotland - 26 December 2012

Around the west of Scotland Portpatrick reception can be difficult to impossible because of topography. On 518 kHz, Malin Head broadcasts Sea Area forecasts for Shannon, Rockall, Malin and Bailey (as well as Irish Coastal  and some High Seas Areas).

The MCA has been in negotiation with their Irish colleagues. The result is that, after a little more trialling,  Malin Head will use the 490 kHz, national NAVTEX frequency to broadcast UK Inshore Waters forecasts. Areas will be the same as Portpatrick, i.e. Land's End to Cape Wrath, the Minch, Lough Foyle to Carlingford Lough.

The B1 letter will be A so that broadcasts will be every four hours from 0000 UTC. There will probably be one slot for weather forecasts and two for weather actuals, as in the Portpatrick broadcasts.

Between them, Malin Head and Portpatrick are expected to give good reception over much of the area. 

The three UK NAVTEX stations will continue to broadcast four Inshore forecasts each day. However, that means that actuals will only be broadcast at the other two slots. There is simply not enough time to do otherwise at present.

WMO Survey on Weather Forecasts - 26 December 2012

The WMO are running an ongoing survey on the usefulness of weather forecasts to the mariner, with the emphasis on the official GMDSS products (e.g. NAVTEX, SafetyNet, WxFAX etc.).

To take part, follow the link.

You can also see results of the survey from 2011, compared to a baseline of 2009. Key points are:

  • SafetyNet over INMARSAT C is very good
  • NAVTEX suffers from poor coverage in many areas
  • VHF voice forecasts are very good
  • WxFax suffers from reception problems
