To me, looks like the one in blues is wearing the original braid, and the one in whites may be wearing the new straight/green braid.

I think if you look closely the transmitters and receivers are completely different models.

R651400

Ships call sign list for 1963 gives the Aureol call sign as GMGJ. No Ikega Palm at that time only Ikeja Palm GHMJ. Hope that helps at least in part.
Regards
John

Two different ships....

One has the reserve tx next to the main, with only one rx.
The other only has the main tx visible but has two rx next to each other.

The early station has an Oceanspan MkI (L/C tuned VFO with knob and counter), Reliance Emergency TX, along with Electra and Mercury receivers. The later station has a late model Oceanspan (MkVII?) and an Atalanta receiver.

happy days,

As gwzm says Aureol's equipment was the same as I had on the 1953 Adrastus/GQZN and the 1961 Ikeja Palm (apols for the typo) a much later vintage and looks to have some impressive PA equipment as well.
JL thanks for the call-signs.

The ship is the "Aureol" and the R/O is George Cockburn. The "Aureol" is gone but George is still with us and can be seen, on the last Friday of every month, on display in the "Ivory Peg" in Chelmsford town centre.

Malcolm,

the first one is the Aureol as used on Youtube. She had been refitted when I sailed on her and my mind seems to think we had a Commander. Possibly to early for a Conqueror.
There was also a Reliant with RT. Also think there was an Oceanspan but that maybe memory problems. It is 44 years ago.
Callsign GMGJ.
I am sure Ron will tell us.

Sorry can't help but Stan McNally or one of the other members of his Liverpool reunion group might be able to come up with the answer.

Don't believe that there ever was a version of the Reliance that had R/T but the Oceanspan VIIE was a reserve transmitter that provided MF/HF W/T and R/T on the MF 1.6-3.8 MHz (IF we called it then) band. Not a lot of difference in the appearance to a casual onlooker (or one peering through the murky windows of memory).

Probably "Commander" or "Commandant" would have been used for a refit - the run that she was on would not have justified the extra expense of a "Conqueror". But the refit would have been done on the Mersey so Stan is your man.

Neville/Ron yr postings read like the years have taking their toll. The transmitter in question was the Mimco Reliance.
I took the first practical PMG ever on this innocuous but high performing emergency transmitter which I preferred on MF to the Oceanspan MKVI.
Completely 807 valved I can see it in a radio-telephony role but only with a fair bit of re-engineering on the R/T band coverage side.

Not the memory failing this time, just the association of ideas. I was writing Reliance but thinking Commandant and finished up with a hybrid. I too took my PMG with the "Reliance" as the emergency transmitter and sailed with it on several ships, never ever having a problem with it. As you say, it was better than the "Oceanspan" on MF and it didn't need all those silly vibrator power supplies.

The Oceanspan VI and Reliance on Adrastus if my memory hasn't failed were powered by rotary transformers.
Not sure if this was uniquely Blue Funnel as they also powered their Redifon installations exactly the same way including the R50M receiver which meant you had a constant 600-1000 rpm motor whine in the radio room throughout the entire watch period.

Did my PMG at Leith on Reliance and Oceanspan VI. Then BoT Radar on Radiolocator Mk IV. Joined my first ship and it was equipped with this gear. Made for an easy life and kept in the boss's good books as he had no radar ticket. The Reliance (Emergency TX ) was powered by a rotary converter. Oceanspan was used to drive a PA and the combination was known as Worldspan.

I was at LNC in 1955 when they were installed just shortly before the exam but that's another story!!
Pre MKVI Oceanspans and Reliance were powered by dc to dc rotary transformers.
Oceanspan 24/110/220 Vdc input to 600Vdc output and Reliance 24Vdc to 600Vdc.
The Oceanspan MKVI at LNC I recall was a table top model powered by an AC PSU.
There was also a MKVII Oceanspan which I understand included the R/T band..

For RS651400. I stand corrected. It was an Oceanspan Mk VII when I was at LNC. Same Tx was on my first ship and it did have R/T. It could be operated separate from the Worldspan PA.
No doubt you would have had Mr Bogie and Fred Boettcher for instructors.

Malcolm,

yes I did make a mistake and I changed it after I reread the post. However Ron had not picked me up on it so thought I was right the first time so changed it back. I also took my PMG on said Tx's.
Sorry Ron - I have to blame someone, its a Government trick its always someone else's fault!

With regard to Oceanspan and power supplies, the vibrator power packs that sat in the bottom of early marks of Oceanspan were used to supply the associated receivers. In my time at sea that was CR300 and (I believe) Mercury/Electra. The plug-in vibrators in the power packs had a habit of welding their contacts together and failing, usually at some critical moment when copying a traffic list or handling traffic.

Some time in the 1960's an a.c. power unit was created for use with the Oceanspan VII on refit jobs, where the Oceanspan I or II was being replaced. Since the O'span VII was designed for desk mounting, there was not enough room inside it to take the vibrator power packs. So a steel box, about 30-inch cube, was supplied on which the O'span was mounted to bring it to the correct height for use. Then the vibrator power packs were transferred from the old transmitter and into the box. Loads of space in there.

Regrettably this box was not constructed like an O'span with demountable side and rear panels, instead the sides, back, top and bottom were all welded to form something that resembled a safe, with a front-opening door. Trying to get this through the accommodation doors and into the radio room was a nightmare on any ship, let alone older designs (the ones that were getting the refits) where 21-inch wide doors were the norm. I think that is the worst cock-up that I remember from my time working ashore.

I once spent over a week in a Tyneside shipyard, trying to get all the various tradesmen (deemed necessary by the yard to remove doors and door-frames, cut out steelwork to widen the doorways enough to pass the box through, carry in the box, install a wooden mounting pad, mount the box, weld in plates to close the holes again, paint those plates and then to replace the doors and door-frames) to attend the ship in the correct sequence and allow me (eventually) to install and connect up all the equipment.

I needed only a couple of hours to complete my work of fitting the O'span VII but the entire thing was a marathon. I think that it involved over 20 different men, from 5 or 6 trades. Can't think why shipbuilding moved to Japan and Korea.
