Was there not a proviso that if there was risk of an imminent life or death situation then it could be raised to a Distress. Seem to think this came up in a thread sometime ago. The quote below comes from a current web site for use of the Distress signal.

- The likely emergencies are man overboard, being holed or running aground, fire, and medical emergencies.

Malcolm,

the distress area is almost dead centre from both stations. I cannot now remember what our area was at GIL.
What I would suggest is that this could have happened after the cessation of 500
at GIL and its closure. It was remote during the DOC system. The controlling
station would have been GLD who still had WT.

500 kHz Recordings A9M sends HNY greetings

Hi,

Regarding the DDDSOS de GLD, and the non use of
GIL, I had assumed that GIL had already closed on
500, at that stage, if my memory serves me well,
but stand to be corrected. Just not sure.

Attached is another long haul DX signal on 500 khz
from A9M, sending a Happy New Year greetings
message on 500 khz. This is followed by several
other stations, ship and shore, including an Italian
vessel sending a TR to TriesteRadio IQX. Both are
heard at reasonable strength.

I have found the recording of GNF close down, in
1992, but have yet to clean it up. The original
has lots of noise. With filtering this can be sorted.

Regards
Finbar EJM ( was GMH until 1950 )

Finbar, I see on your profile you're still working at Malin Head. Is Valentia still open too?

500 kHz Recordings Malin Head and Valentia Radio

Hello John,

You asked about Valentia Radio EJK. Yes it is still
operational.
Both stations EJM and EJK were given a huge
revamp over 2 years ago, particularly Malin Head,
where the operations room was transformed into
a much more space saving and effective set up. A
new purpose built command and control equipment
container was installed beside the original building
(built by the GPO in 1913 ). The stations transmitter
room was also re-wired as was the rest of the building.

Both stations use a pair of 150 foot towers, insulated,
and fed against a proper earth mat. Between these towers
is the original 500 / 421 khz Tee antenna. This is now used
for Navtex on 518 khz and 490 khz. The 490 khz
service is to provide the UK Coastguard weather broadcasts
for the North and West of Scotland.

Transmitter power is 1 kw on R/T and Navtex, but the
Navtex transmitter is reduced in power during night time
transmission slots, as per regulation.

I am now retired from EJM, my last watch, a night duty
was in March 2009. I served there for 34 years. I was
the guy who sent the last CQ de EJM close down, CW
transmission, on 500 khz, on the 31st December 1988.

Regards
Finbar

Thanks for the info, Finbar. I was on Valentia last year - it never have occurred to me that EJK was still going but I suppose modern security ideas wouldn't permit a visit.

Malcolm,

truthfully I did not listen to it all too closely. Just thought there was typo in the QTH and just dropped a decimal point into it ie 06.26W hence me saying mid area. Put it off the north west coast of Devon or there abouts.
Had another listen and you are totally correct it does give the psn as 00626.50W but long way from Godalming. If you use 51.15N and 006.26W in Google maps it comes up as I said.

If my memory serves me correctly if we received info from CG it was sent as received until we had QSO'd with them to correct said error. Also when everything went modern as we all know we seem to have ended up with deg,mins,secs, and something else tagged on.
Never thought of 00.6. Personally I would not have sent the info until it had been clarified. How times do change!

Neville.

500 kHz Recordings Malin Head CG Radio EJM MRSC

Hello R651400

You ask a very interesting question regarding co-ordination of distress and rescue at Coast Radio Station in the UK and what the situation was and is at our Irish Coast Radio Stations.

With our history of being a UK coast radio station, GMH, up to the 31st of December 1949 and with the formation of the Irish Republic and the break with the British Commonwealth at midnight of that day, the station was from then fully run by the Irish Post Office, callsign EJM.

I can only comment on the proceedure for co-ordination during the 1960's onward, which was done by the Irish Navy, at their base at Haulbowline, in County Cork. Effectively the nations marine MRCC.
This was transferred to ATC at Shannon airport in the early 1970's
and remained like that until the coast radio stations were moved from Post and Telegraphs to the Department of Marine, in 1993 and we
got a new name for our service, IMES, Irish Marine Emergency Service. The MRCC function was moved from ATC Shannon to the new HQ, in Dublin. This was manned by marine Radio Officers and
the VHF coverage for Dublin and Wicklow, which had been controlled from Malin Head Radio was also transferred there.
In 2000 both Malin Head and Valentia also became MRSC's.
This is the current status for all 3 stations.

The operation of joint MRCC/MRSC/CoastRadio stations is a much
more efficient and effective situation and has worked very very well.

Might I add that we manage rescue for much more than the marine
area. This includes the Inland river and lake system ( with two VHF
stations, Lough Ree CG Radio, controlled from Malin Head, and
Lough Derg CG Radio, controlled from Valentia ). Island medical
evacuation to hospital. Mountain and Cave Rescue, plus hospital to
hospital helicopter transfers by our 4 dedicated helicopters. Cliff
rescue, lifeguard and missing persons search and rescue, is also
part of our remit.

Needless to say Weather broadcasts, Navigational warnings, taking
TR's ( from the many island ferries), Gale warnings and running the
Navtex system. We now cover the West Coast of Scotland on Navtex for UK Coastguard weather broadcasts, on 490 khz.

Sadly, a few years ago, we lost our Link Call service, though the
phone patch system is still used in medical emergencies to facilitate hospitals to talk directly to ships, via MF or VHF.

AIS is monitored and is available from all our sites.

Finally, I can confirm that, from my experience, coast radio stations work far better, when, with proper training, they co-ordinate their
own distress and rescue work. Might I also add that staffing stations with people who have worked and have experience of life at sea
is vital. The just KNOW what it is like out there...
Staff training is carried out every 3 to 4 years and entails 3 weeks
at the National Maritime College in Cork.

Best regards
Finbar EJM ( Retired)

500 kHz Recordings NorthforelandRadio GNF QRT 500

Attached is a recording of the closure of Northforeland Radio GNF
on 500 khz, in 1992.

It is surprising that no other UK coast station calls or acknowledges
the broadcast from GNF.

The recording is longer than the actual broadcast from GNF, to
give athmosphere to the sounds of radio traffic on 500 khz at
that time.

Regards
Finbar EJM

"Agreed Neville but if that extra zero on the longitude was misconstrued to QTH 51.15N 00.626W my GPS registers it as nr Godalming."

Just as an aside, there is a memorial to Jack Phillips, the RO on Titanic, at Godalming, from whence he came. Spooky or what?

Is that the correct year Finbar? Think it might have been somewhat earlier. (You may still be able to edit it).

500 kHz Recordings GMH to EJM 1st January 1950

Hello Ron and Jim,

I can confirm that both Malin Head Radio and Valentia Radio
used their respective British callsigns, ie GMH and GCK, until
the 31st December 1949.

There is clear notation of the callsigns used and the move,
in records of the period. Historical records can be examined at
Kew.

Jim, the website link you quote is wrong regarding the
changeover year. Use of EJM and EJK started on the 1st
January 1950.

I also note that the IOWT ( Inspector of Wireless Telegraphy)
writes, in May of 1949 that Oban Radio Station will open
at 0800 gmt May 16th, on a temporary experimental basis,
call sign being GNE. Watch on 1650 kc/s, Oban transmitting on
1650, 1841 and 2500 kc/s A3. Service for small craft only.

W/T sked times given ( several). Oban will call ships on 1605 kc/s
A2

Regards
Finbar EJM

Got to say a big thank you again, Finbar. That recording of GNF closedown and all the others was a really good thing for me to hear again. Any more would be greatly appreciated, especially from my time in the '70's.

Perhaps you could make some sort of archival recording of the whole, be a bit of history, that.

Best regards. Paul

500 kHz Recordings AlexandriaRadio SUH on 500 khz

Here is another recording on 500 khz, this time
the Egyptian station Alexandria Radio callsign SUH.

From my research this was one of 4 Egyptian
coast radio stations on 500 khz, as follows :

Alexandria Radio SUH
Ismailia Radio SUQ
Tor Radio SUT
Qoseir Radio(Kosseir) SUK ( Pilgramage Season only ).

Again, this recording was made at my home near
Malin Head.

Finbar

You must have stayed up late to be recording such a nice clear SUH, Finbar. I notice their working frequency was 444 - could be mistaken but I think that was the same as DAN.

500 kHz Recordings Palestine ZNL and 4XO

Greetings,

SUH and his working frequency 444, was for a time the same as TAH.

Now another recording and a bit of history.

This recording is of Haifa Radio 4XO on 500 khz.

I have looked up my treasured 1950 and 51 copies of ALRS Vol 1
and found a lots of marine radio callsign history.

Here's some from the 1950 copy.

Bahrein Radio callsign GOU 500 and 478 kcs 1Kw

Ascension Island callsign ZBI 500 kcs 250 watts

Under the heading Palestine :

Jerusalem callsign ZNL 500 and 484 kcs 1 Kw
( station temporarily closed 1949 ).

ALRS Vol 1 1951.

Under the heading Palestine :

Haifa Radio callsign 4XO 500 and 484 1Kw.

This recording from the early 1990's shows they
were still using the original 484 khz working frequency.

Regards
Finbar

500 kHz Recordings Greenland and Cape Verde

Here is another of my recordings of 500 khz.

This clip features Aasiaat Radio OYR 68 42 N 52 45 W
at the southern end of Disko Bay, on the West coast of
Greenland.

The other coast radio station is from a much warmer
climate, Cape Verde D4A.

Both stations are at quite a distance, but collectively show
the huge range this frequency is capable of being heard
at, when conditions are just right.

Receiver used was home made, the antenna a 10 foot
tuned helical. Recordings made at Malin Head.

Time of recording was 0130 UTC on the 6th January 1994.

Finbar EJM

Thanks Finbar, never known 500Kcs so quiet! However where on earth was P3QO2 registered? (Calling FFB) sounds like the callsign of a lifeboat tx calling the mother ship - usually ended with mother ship callsign with a (2) after it.
