Talk:Y service

Woodcock Hill
Apologies I just tried to add a Y station and have forgotten how to enter it correctly, I haven't done any editing in a long while! this needs to be added to Woodcock Hill Pandaplodder (talk) 13:10, 15 January 2024 (UTC)

Cooling Marshes in Kent
I believe there was also a Y Station (not mentioned in the list in the article) located near the GPO Receiving Station on Cooling Marshes in Kent. 2A00:23C6:B631:3101:4014:3D7D:8FA5:8019 (talk) 15:26, 12 June 2023 (UTC)

Source for locations
Is there any source for the various locations? Some of them look dubious to me.

Budiansky in Appendix D of his book lists the following as stations (with the number of receivers in parenthases) that were part of the intercept network. 

"GC&CS in mid-1943 was receiving traffic from a far-flung network in the United Kingdom.

Royal Navy: Scarbora [sic]	(72), Flowerdown	(45), Chicksands	(16), Cupar	       (15), Shetlands     	(2) Army: Beaumanor	(140), Harpenden	(23), Keddleston Hall	(36), Mobile units	(6)

RAF: Chicksands	(105), Cheadle	       (75), Kingsdown	(15), Waddington	(24), Tean	       (19), Wick	       (14)

Foreign Office: Brora	       (14), Cupar	       (13), Denmark Hill	(23), Sandridge	(54), WKitchurch	(40), Knockholt	(35)

Post Office: St. Albans	(8), Coastal stations	(9)

This was supplemented by overseas stations in Canada (Ottawa, Winnipeg, Grande Prairie, Point Grey, Victoria), Malta, Gibraltar, Alexandria, Cairo, Baghdad, and other sites in Egypt, South Africa, West Africa, and India."

So there is quite a bit of research needed to get this right.

YES, the National Archive file:- HW 41/401 Title:- Y Stations Lists and Locations It contains a collection of original declassified WW2 documents. The lists are quite comprehensive but it must be borne in mind that, throughout WW2, stations were opened, closed and occasionally changed hands between the various authorities that operated them.

 * So primary research rather than secondary sourcing?

ww1 vs ww2
It is just about impossible from the article to see which stations were ww1 and which ww2. I would imagine some existed during ww1 and more were built, but who knows? The first two in ww1 seems to be stockton and hunstanton. 07:33, 13 August 2010 (UTC).

German articles
German wiki has articles on each station which I'm tempted to translate - the location for Denmark Hill is wrong I'm sure as it's the railway station https://de.wikipedia.org/wiki/Denmark_Hill_Y_Station Secretlondon (talk) 18:06, 24 February 2019 (UTC)

Denmark Hill Y Station (more precisely: Metropolitan Police Wireless Station at Denmark Hill) was a radio listening point of the British secret service. It was inside the then Metropolitan Police Department at Denmark Hill, a suburb just south of central London in the Southwark borough just north of Herne Hill. During the Second World War, Denmark Hill was an important radio station (Y station) of the British Government Code and Cypher School (G.C. & C.S.) (German about "State Code and Cipher School").

contents 1 history 2 literature 3 Web Links 4 References History [edit] The radio listening post was set up in the police station on Denmark Hill in the 1930s and initially led by Commander Harold Charles Kenworthy (1892-1987), who later, in June 1942, headed the newly formed Government Communications Wireless Station (GCWS). Ivy Farm in Knockholt (25 km southeast of London) took over. Between 1934 and 1937, the focus was on intercepting secret Soviet radio broadcasts with the Communist Party of Great Britain. [2]

From 1939, after World War II, the station hosted one of the War Office Y Groups (W.O.Y.G.) of the War Department, whose mission was to intercept and record hostile radio communications. The listening post Denmark Hill specialized in intercepting and recording German high-speed radio broadcasts. [3] Here, in the second half of 1940, the British succeeded for the first time in catching the brand new German radio telegraph traffic, which distinctly differed from the usual sound of the Morse code. They first gave him the nicknames new music ("new music") and NoMo for No Morse ("no Morse"). A little later, radio broadcasts of this kind were grouped under the code name Fish ("fish"). Due to lack of capacity and resources, these messages were initially tracked only with low priority and could not be deciphered. The cryptanalytic collapse then succeeded in the second half of 1941 (see also: cryptanalysis of the Lorenz machine) by the British Codebreakers in Bletchley Park. After successful deciphering and intelligence evaluation of the intercepted German radio remote, the British summarized the often important warlike information under the code name Ultra and used it for their own planning.

Immediately after the war, the radio station was abandoned on Denmark Hill.
