I had wondered, before I saw Vince's email, if there's the station might have been for VHF naval traffic, at least in part. Since Hallicrafters were being used and the aerials appear to be very high, that seems to be quite likely. The S-27 was definitely used by the RN , including Headache parties on board ships, for intercepting VHF. German destroyers, as well as E-Boats, used VHF. Is Vince's reference to an 'octagonal DF structure' a reference to VHF DF aerials? I'm not really familiar with them, since I've concentrated on HF-DF. As someone else hinted, Geoffrey Pidgeon is the real expert. Have you or Vince tried him? I attach a few pdfs on HF-DF stations. You are welcome to use this material in any way whatsoever in your own work (including publications). I would merely ask you to observe my 'standard condition' (I apply this even to my friends), which is not to pass it on to anyone. You may mention it to them, and refer them to me, giving my e-mail address. Kind regards Ralph Erskine
