T1083 Transmitter set - UK Vintage Radio Repair and Restoration Discussion Forum

Avro683 · 12th Feb 2015, 2:29 am

Hi folk's a friend contacted me to see if I could find out about some parts a fellow had brought in to him today. It is a T-1083 transmitter and associated parts and the fellow wanted to know if there was any interest in them and possibly a rough idea on price?
Look forward to hearing from you ..

Hi,

Interesting set, I have never seen one before, as for value see what it fetches at auction.
I would put a reserve on it of £150 and wait and see what happens.

You don't show a picture of the transmitter, only the plug-in coils.
A complete transmitter is rare, might be worth £600 upwards.
Coils maybe £20 each? They do turn up more often.

Am I wrong or was this the tx used on the Spitfire?

GMB · 12th Feb 2015, 11:50 am

Nothing to do with spitfires.

It is also not a T1083, but some plug-ins for it.
An actual T0183 is worth a fortune as they are super rare. The last one I saw for sale fetched over £1200.

The plugins don't seem to be in such great demand by the one or two museums who own the actual transmitters. (Wish I had one!) and haven't fetched much money in the past.

Thanks for the replys, I was only going by the plate on the one that said 1083. This is all the pictures that were sent to me so I am guess there isnt a transmitter then?

M0FYA Andy · 12th Feb 2015, 4:03 pm

The T1083 Tx and R1982 Rx combination were used on the WW2 heavy bombers prior to the introduction of the more familiar T1154/R1155 combination.
Certainly fitted to the Wellington, Stirling and Halifax, and I think maybe also to early Lancasters.
R1082's do turn up, although I wouldn't call them common, but T1083's very rarely, from my observation.

Thanks Andy, Apparently he doesnt have the transmitter he only impulse bought these at a antique place..

jamesinnewcastl · 14th Feb 2015, 5:40 pm

Heres an R1083

M0FYA Andy · 14th Feb 2015, 9:37 pm

Hi James, you meant T1083, not R1083..............

I've managed to find a picture on the web showing the T1083/R1082 in a Lancaster.

Andy

jamesinnewcastl · 14th Feb 2015, 9:49 pm

Hi Andy - True

There is a switch on the side that says S, Off and R that I have just noticed. Send -Off- Receive. Was only the Send bit connected?

James

HamishBoxer · 14th Feb 2015, 9:53 pm

That wavemeter shown (Jamesinewcastle) do we know the type number as I certainly have similar.Bottom right.

M0FYA Andy · 15th Feb 2015, 2:02 am

James,
From looking in AP1186, that switch on the side is part of the mechanical Bowden-cable operated remote control mechanism. I'm not clear what you mean by your question 'was only the Send bit connected?'
Your picture is titled 'Skua Transmitter' - was the Fleet Air Arm Blackburn Skua fitted with this? It's not an aircraft I know anything about.
Andy

jamesinnewcastl · 15th Feb 2015, 12:12 pm

Hi Hamish

The Wavemeter is a W.66 (10A/7640) I have a section from A.P.1186 (section 5 Chapter 6) if you need it. The AP has other wavemeters but they don't look like the W.66.

James

jamesinnewcastl · 15th Feb 2015, 12:39 pm

Hi Andy

I have to confess I was being lazy as I have the AP and could have looked the answer up myself - it seemed odd that a transmitter would have any function when in 'receive' apart from just keeping quiet, but I now suspect that the remote would have been linked to the R1082 so that they could be switched by a single control.

My particular interest is the Stirling where the T1083/R1082 would have been the preserve of the W/O but I can't see any remote control for him and the R1082 doesn't seem to have a Send/Receive switch so was the receiver on all the time?

No need to answer these questions now as I plan to quiz the Forum later on the whole of the Stirlings radio set up.

The picture was lifted off of a web site but sadly I have lost the link to it.

Cheers
James

M0FYA Andy · 15th Feb 2015, 2:04 pm

James,
What is needed is the aircraft wiring diagram which includes the T1083/R1082. The Stirling AP I have (which may well have come from you?) shows the T1154/R1155, so too late for what you are looking for.
The R1082 may well have been active all the time, it is fitted with a diode valve across the aerial input circuitry to prevent it being swamped by an adjacent transmitter. But I assume the aerial was switched between Tx and Rx, I don't think the Rx would survive being directly connected to the Tx output!
Andy

jamesinnewcastl · 15th Feb 2015, 2:32 pm

Hi Andy

I have got the earlier circuit and while it is very useful it suffers from the usual 'why do you need to know what this is haven't you got one in front of you?' situation where the symbol or code meant something at the time.

There's no J-Switch or explanation of what a Type 1 antenna is. I going to prepare a question for the forum but need to get all the drawings ready, hopefully the whole system will be laid bare!

James

M0FYA Andy · 15th Feb 2015, 4:15 pm

Hi James,

It would be very interesting to see that circuit. Was a TR9 also fitted in the same installation?

Andy

Avro683 · 15th Feb 2015, 4:32 pm

Thanks for the picture
