I have recently identified this building near me from wartime AM RSPs, on which it is referred to as a 'VFT Apparatus Building', and 'DTN Building', to drawing number 1755/41. It is situated about a quarter of a mile outside the former airfield boundary at Wick.

I have unearthed a little information about the Defence Teleprinter Network and Voice Frequency Telegraphy, but I would like to know what this building actually was, it seems too big for just an airfield teleprinter system, but I can't find anything on the actual DTN infrastructure.

Can anyone shed any light on this structure, what it was, what went on inside it, what the rooms were for or how it fitted in to the DTN system?

Thanks

There are pictures of the DTB equipment bays on the BT Telecom Archive.

Also this article about the DTB

I was sent a 1945 copy of the DTN Operating Instructions but don't think of any help!

If you look at the pictures of equipment racks, there would several of them in one room, batteries, generator and probably some accommodation - bog, eating etc.

By the way what is the position on the airfield? Perhaps you can add it to the Canmore and HER entries for Wick.

Thanks Martin, yes the POEEJ is where I found most info about DTN, but its mostly about the equipment, technical specs and tests and the like, only passing mention about the network's layout/connectivity, just vague generalities.

I presumed that the rooms contained GPO switch gear and the like for the teleprinter network, but a big building like this for one aerodrome seems excessive? and I have not seen this type of building at other airfields. So was this just for RAF Wick, or was it some sort of hub, did it connect all RAF/military sites in the county, was it a stage point in the main DTN network carrying it on to Orkney and Shetland?

There is no evidence of any bog in the buildings, so does this suggest it was not permanently staffed? No H&S etc. in 1940's wartime to comply with :)

There is not a record for the building at the moment but you can add the images and information to an existing record for the Airfield.

You can register here

canmore.org.uk/

Once registered then you can add pictures and text to any record on Canmore.

You can also send it to them in EMail if you think it needs to have a new record

canmore.org.uk/content/contact

I find the best way to find Canmore records is PASTMAP, also a very good map source.

pastmap.org.uk/

If you zoom in and click on Canmore

DATA LAYERS

There is then a dot for any Canmore records, clicking on the dot takes you to the record.

If you click on Historical Environment Record then it takes you to Highland HER and will show if they have a record.

They have a different system

Wick Airfield, Pickett-Hamilton Fort

Details takes you to the record

If you scroll down then you can add comments and images via Discus using "Start the discussion"

You can also work out the NGR using either of these - usually NGR is displayed for where the mouse is hovering.

You can also quickly work out NGR using this site

Zoom in and right click on location.

Must get back up to Caithness, been around many of Y Service sites
