Coast Station Index



MALINHEAD Signal Station was opened in June 1902 and operated by the Marconi Marine Company on behalf of Lloyds with the callsign "MH". Located at the northernmost tip of Ireland, this station was ideally positioned to communicate with shipping coming across the Atlantic or from northern waters.

The station was then held by the British Post Office from Lloyds on an underlease for 99 years dated 1 November 1902, at a rent of 10/- (ten shillings) a year. The Post Office then purchased the Malin Head station from Lloyds (Shipping Corporation) under an agreement dated 1 December 1909 which also included the stations at Browhead and North Foreland, the total purchase price being £2400.

In 1912, the station's callsign changed to "GMH" to reflect the change to national identity in callsigns.

The station was transferred for use by the Admiralty on 2 March 1918.

On 22 May 1922 control of the station was taken over by the Irish Provisional Government as agents for the Post Office .

Even with the formation of the Irish Free State the station retained it's GMH callsign since Eire was part of the British Commonwealth. But on 1st January 1951, following Ireland's withdrawal from the Commonwealth to become a Republic, the station again changed callsign, reflecting the nation's identity, to "EJM".

For many years the station was primarily a WT (Morse Code) station operating in the 500kHz band. Although telephony facilities were available on 2182kHz and 1841kHz, the station could not offer shipping a "link-call" service - this was something which always mystified those in the UK Coast Station service since EJM had superb coverage of the North Western approaches to the British Isles. There was a practical problem to providing such a service and that was the antiquity of much of the Irish Republic's telephone service. The telephone at EJM was once described as the lines strung out over the bogs (and often brought down by the gales) with the telephone having, as in the old Western movies, a microphone built into the main body of the telephone, a separate earpiece and a handle to turn to call the operator!

Joining the EEC brought money into Ireland, including into the Republic's telephone network. Malinhead Radio was, somewhat belatedly, brought into the "modern" age of telephone link calls! Further expansion followed with the introduction of VHF services from Malinhead and a number of remote stations.

The end of one era for EJM came at 2359 hours GMT on 31st December 1988 when the WT (Morse Code) service on 500 and 421kHz closed down. A tape recording was made of the final broadcast and farewells from other coast radio stations - and, as the echo of the final tone of the key died away, the sadness of this event could been heard in the voices of the duty Radio Officer's with a background comment of "it's gone".

It might be argued that the Irish authorities were rather early in closing the 500kHz from such a strategically positioned station. Indeed there was one incident when the station's 500kHz automatic alarm receiver, which remained on watch, was activated by the signals of a sinking ship far out in the Atlantic. EJM was the only station able to copy the weak signals from the ship's lifeboat and, with the station's transmitters dismantled, return transmissions had to be made by her sister station Valentia Radio/EJK - not the most ideal means of conducting a distress situation.

(NOTE:- EJM's callsign  "mysteriously" re-appeared twice again on 500kHz.   Once when, late on the evening of 31st January 1997, the station participated in the historic closedown of the United Kingdom's 500kHz service.  Then again late on the 31st January 1999 into the early hours of 1st February 1999 - "GMDSS day" - the day when Morse Code ceased to be part of the international distress system for shipping)

The closure of EJM's 500KHz WT service came as a result of the gradual introduction of GMDSS (the Global Maritime Distress and Safety System) in which Morse Code plays no part. But this new system has, unlike Coast Radio Stations in many other countries, given Malinhead Radio a new lease of life.

Unlike the United Kingdom, the Irish Republic had no Coastguard system. There was however a need for a Search and Rescue Coordination organisation. It was determined that this should be based on the Coast Radio Station service.

A Maritime Rescue Coordination Centre was set up in Dublin with the introduction of a NEW Coast Radio Station "Dublin Radio" operating on VHF only. At Malinhead and Valentia the Radio Officers, already well aquainted with and highly professional in handling distress and safety communications, took on the additional task of coordination of rescue effort and the GMDSS facility of DSC (digital selective calling) was added to the station's facilities.

In May 2012 a major refit of the operations room at Malinhead commenced which was completed in August of the same year.

The decision by the Irish Republic to base their coordination on professional communicators using professional equipment, ensured that those who sail the northwest Atlantic remained are in competent hands. However there were later attemps to close Malinhead Radio down which resulted in an outcry and a campaign which successfully ensured the retention of the station, now known at Malinhead Coastguard Radio. The continuance of the Malinhead, Valentia and Dublin coordination centres was confirmed in a document dated 28th November 2012 - the full text can be viewed here - an adridged version follows:-

One aspect of the review which has attracted significant interest is that of the future of the co-ordination centres at Dublin, Valentia and Malin.

There has been considerable interest in this matter.................

In my Department’s review of the Coast Guard and Marine Survey Office services, all options have to be considered. That necessarily included looking at whether the current configuration of co-ordination centres was appropriate and whether changes to that would deliver greater efficiency. This was all within the context of the expenditure and human resources constraints that my Department operates under.

However, after careful consideration of the various options available, I will be proposing that the three centres will remain open and that none will be closed.

Rather, through the utilisation of the most modern communications and IT infrastructure across a single national Coast Guard network, I will be proposing that the three centres will be more closely aligned and integrated. Therefore the current structure of three Coast Guard Centres in Dublin, Malin and Valentia will continue to provide their current service but will be required to deliver new efficiencies in how these services are provided. External consultants are undertaking work on the details of this at the moment to assist in the preparation of the Action Plan.

The above photographs of EJM were taken In October 1996. The Radio Officer on duty is Mike Mullins .

My thanks to Mike and to Finbar O'Conner who entertained me during that particular visit. Thanks also to the others I've met during other visits to the station and those who assisted GTST with WT, RT and DSC tests in my Radio Surveyor days.

Finbar retired from EJM in May 2009. He has created a number of historical recordings from and about EJM which can be listened to or downloaded from Internet Archive
