Emailed information about the HF/DF Station at Kenovay. Built in the utmost secrecy during WWII, it was used to track aircraft and German U-boats, and was key to D-Day operations. After the war all traces of it were carefully removed.
“It was certainly in use on D-Day! Its exact location I cannot be sure of but its intended location was MKJM 06593073 using the Georef system which places it at latitude 56 30 43.8N longitude 006 53 24.6W and its role was vital in securing the return of Coastal Command weather recce aircraft. D-Day was to have been 4 June but Gp Capt Stagg advised General Eisenhower that the weather was a no-no but he had reports from a weather ship that indicated that rising pressure and temperature were likely to push the worst weather North. An elite crew from 518 Sqn on Tiree were tasked to probe into the weather patterns and establish whether or not this was true. They signalled back to the disbelief of the boffins at Dunstable who said “Rubbish!” but the Polish Met observer put them straight and after nine and a half hours the aircraft returned safely thanks to the brilliant crew and also the radio fixes from Tiree. The flight data was absolutely crucial to the D-Day plan. Well done 518 Sqn!!! It was a true team effort by a marvellous crew of eight, Stagg was right, Eisenhower trusted him and D-Day went ahead.”
