In recent months I have discovered a number of Facebook sites which show pictures of the radio rooms of various merchant marine ships. Eddystone supplied a number of Marine Radio Communications companies, throughout Europe with Eddystone receivers. Usually they were badged under the name of the company (MIMCO, Debeg, Hagenuk etc) who supplied and had responsibility for the radio equipment, and the provision of the ship’s radio officers. The role of Radio officer was phased out in the 1990’s with the introduction of the Global Maritime Distress and Safety System which was a maritime communications system used for: emergency and distress messages. vessel-to-vessel routine communications. vessel-to-shore routine communications, Radio Officers often retrained as Technical or Engineering Officers and stayed in the Merchant Marine or took land based jobs.

I like to see if I can recognise sets of Eddystone origin in some of the FB pictures. EC958s and S830 seem to be the most popular main receiver with S1002 taking the role of the reserve receiver. There is also a Eddystone Radio Owner’s FB page which whilst nothing to do with the Eddystone User Group does throw up some interesting sets that are still in use by their current owners. The links to FB pages are shown below.

A friend of Gerry O’Hara VE7GUH sent him the photo below of an S880/2 together with a Marconi Atalanta, mounted in an unusual shallow-angled console aboard the ‘Tonga’, a bulk carrier vessel operated by Wilh. Wilhelmsen in Norway, in the late 1960’s. Gerry thought having S880/2 on a ship was unusual?  This was found on the Marine Radio Group site (see below)

 

I found the following picture of a very young operator in charge of the radio room of a supertanker with the callsign A8VD with what are clearly two S830 sets on the FB page of the The Marconi International Marine Communications Company (URL below)

 

 

The picture below shows Norwegian Ship MV Kingsville with Radio Officer Per Mikalsen operating another S830 which was published on the Maritime Radio Group FB page

Those of you who are members of the Eddystone User Groups.io forum will have seen the generous offer on17/3/23 from Andy in  Northumberland of a S640 receiver and S688 speaker Free of Charge to someone who would give it the TLC it deserves. Following his mother’s passing Andy had found the receiver, which belonged to his father, whilst clearing her loft space and he remembers having it in his bedroom as a youngster more than 40 years ago. The set and speaker were quickly claimed by Mike who lived in the same area  and picked up by him the same day.

 

 

 

 

 

 

 

Mike contacted me to confirm he had picked up the sets and sent in few photographs of himself with his  S940, which he bought new in 1968, waiting for BBC World Service to come on air whilst working in Boston, Massachusetts in 1971. The second picture shows Mike, repairing the RF stage on that same S940 in Northumberland 40 years later. The third picture shows Mike’s impressive collection of Eddystone sets.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

My collection moving from left to right an 850/4, my 940 under repair, an “as new” 830/7, an EA12, 770 MkIIR and 770U MkII and an 840C.

Intrigued by such a layout, I asked Mike if he would give us some history about his love of Eddystone’s. He graciously obliged.

Mike’s Story

“I purchased my 940 from Aitkin Bros in Newcastle in late 1968. I had seen a 840C in their window along with a couple of the smaller transistorised models. Aitkins was where we went in Newcastle to buy valves and other radio and TV components and even to get valves tested for a fee. So after some thought I went in and put a £5 deposit on a 840C. But I picked up some brochures at the same time which included one on the 940. So I went back and changed my order to the 940. When it came in I carried it home on the bus with some difficulty. Later I ordered a plinth speaker directly from Eddystone. Around that time I saw an advert in Wireless World which covered the 830,770R and U so I always wondered about them.

 

Then I was transferred by my employer to the United States near Boston where I lived for many years and took my 940 with me, originally working in Image Analysis Scientific instruments and later in NMR (Nuclear Magnetic Resonance) and MRI which are both radio frequency technologies. Whilst in the US the BBC sent me a monthly program and that is what I have in my hand in the photograph.

 

I was repairing the RF stage on my 940 after Gerry O’Hara had asked me to make some voltage measurements for him. I had not been using my 940 for other than local radio stations at the time and had not realised that there was a fault but in checking for Gerry I found the usual out of spec carbon resistors so set about replacing them using Graham Wormalds tips for this awkward job. I had gotten to know Gerry when I appealed for some help with the repair of my 770U MkII and Gerry replied. Later by chance both of us together would be replacing and tuning new turret coils at the same time. In my case the Band 3 and 6 coil substrates had deteriorated and crumbled through damp. I did more work on my 770U MkII than any other radio tracking down an intermittent IF gain problem which turned out to be in the coils of the first 50 MHz IF transformer. This differs from the second 50 MHz IF transformer in that it is a a wider band tuning but only the narrow band second stage transformer was available and that worked just fine. I used a modern Marconi digital signal generator to align the set as I did not have much luck using the higher harmonics of my old AVO sig gen.

 

I also owned at one time an EP17R VHFand an EP20 HF Panadapter and used the EP17R to align my 770U and this work is featured in Gerry’s Detectors and Discriminators article. Also owned a very early 888 but sold that when I got the EA12. My other hobbies are E-Type Jaguars of which I have two so sticking with the “E”

Some additional photographs”   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Thanks for the story Mike. Good luck with the S640, but you might need a bigger bench

Saw this picture on Facebook this morning and it had the caption ” Even Santa collects vintage radios”. Merry Xmas and a Happy New Year to all our readers

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Steve in Stroud, Glos is looking for an I.F. transformer for his S750 radio. The one he needs is marked as 3^rd I.F. on the circuit diagram and has the part number D1535 stamped on the base plate, it’s the final 85KHZ variable bandwidth one, ( see attached picture). The secondary winding is O/C and Steve has checked the connections from the terminations of the coil to the connecting wire links and no break is visible so the failure is deep within the coil itself unfortunately. If you can help Steve contact him via e mail SteveJawor60@outlook.com

 

 

 

 

 

 

 

 

 

 

The Eddystone User Group website was started in 2006 when EUG Administrator and Newsletter Editor, Graeme Wormald G3GGL, decided at 75 years of age it was time to retire. The objective was to take all the Eddystone service manuals, archives and newsletter information that Graeme had written, collated, found and stored over the years and load it on to a single website where it could be freely downloaded by any Eddystone enthusiast. To this was added articles on the Restoration of Eddystone receivers, mostly produced by Gerry O’Hara VE7GUH, but added to by others who wanted to share their experiences. To date we have some 60+ restoration articles from various authors  plus 28 Technical Shorts written by Gerry, each focussing on a specific technical issue in repairing and restoring these receivers. We encourage anyone, who wishes to pass on their experience working on Eddystone sets to write it up and submit it for publication.

Every so often we get to hear of someone who purchases a set with the sole aim of getting back to factory specification (or even better). No small feat when we remember we are talking about radios which could be anything up to 80 years old and, of course, not everyone has the skills or facilities to be able to do such a thing.

Victor Jenkins purchased a Eddystone 888A together with S meter and speaker which had been generously donated to the Eddystone User Group by a long time member Richard Hall GM0OGN, to raise funds to keep the website running. Victor paid a very generous price for the trio which were in nice cosmetic condition even though I had not powered the set up. Victor is well known for the thoroughness of his restorations and as a retired electronics engineer knows his way around valve circuits. He has now fully restored his 888A and kept a diary of his experiences which we are publishing here. It makes a great read and takes us through the ups and downs of working on these old sets. I hope you enjoy it. I certainly did and thank Victor for sharing it with us.

PS.    Your Administrator and the EUG gnomes wish all EUGers a Very Merry Xmas and a Happy New Year. These are difficult times but if anyone is feeling generous, a donation towards the running costs of this site and the EUG groups.io forum is always very welcome.

 

 

UPDATED 23/12/22

Andy Humphriss in Stratford upon Avon is looking to acquire the following for his E.C.R. receiver:

1. Original copy of the Eddystone E.C.R. Manual,
2. Mains transformer (can be re wound )
3. Crystal phasing /Selectivity unit in a die cast box, (NEW ITEM)

If you can help Andy contact him on andrew.humphriss222@outlook.com

 

 

 

Pete Williams VK3IZ in Brisbane 4034, Australia is going into residential care and has an Eddystone 750 receiver he would like to sell to someone  who can make  a  sensible offer  and who can also organise collection or a courier. Pete can be contacted via email  jupete@internode.on.net 

 

 

 

Bob Clifford in Bromsgrove, Worcs, is looking for a replacement original power transformer for his recently purchased S640 as the one in-situ is non standard. If you can help Bob please contact him on bobaclifford@icloud.com

 

 

Alan Cavender, near Hexham in Northumberland, is looking for an Eddystone speaker for his 730/4 receiver.  If you can help Alan then please contact him via e mail  alcav@yahoo.com.

 

 

 

 

 

Martin Evans in Alton, Hampshire has an S640 receiver which he bought as a teenager in about 1970 and used through his school and university years.  It hasn’t been powered on since cf. 1980 and has collected dust in his loft space until now.  He recently moved house and decided that he was unlikely to have the skills or motivation to restore the set.  Martin is looking to donate it to someone who will give it the care and appreciation that it deserves. As you can see from the pictures the set needs a good clean up but Martin says it was working when last used, and the mechanics of the stringing mechanism seems OK. There is some rust on the case and internal frame. 

Given the weight of the set it would need to be collected or a courier organised by whoever collects it.

If you are interested in this generous offer then please contact Martin via email
