Hi Stuart

/Re: It would be interesting to know what the station was intercepting. 
I believe you are right that Eboat VHF transmissions was one of the 
items, but the taller masts must have been for other purposes? /

Are referring to the four masts at the north of the site? I've not yet 
been able to establish what these were used for, but I think they were 
probably too far away to be associated with the Watchrooms in the IWM 
photos.  The fact that there are four masts in a square suggests that 
they might have been used for HF direction finding, although this is 
only one possibility.

I'm pretty confident that all the structures shown in the IWM photos 
were at Easton Bavents, as I was able to find evidence on the aerial 
photo from 1945.

When I first found a reference to Southwold Y station, like you I 
initially thought that that it was probably at Gun Hill.  If there was 
then it may have been an intercept only station, with Easton Bavents 
coming along later for direction finding.

It's entirely possible that there was a station in Stone House or one of 
the other large houses, and if it was for intercept rather than DF then 
the aerial could have been quite discreet. For example, there was a RN 
'Y' intercept station in a terraced house on the Seafront at Gorleston.
