HiFix/Hyperfix Links

There isn't a lot of information about Hi-Fix and Hyperfix on the web. An article in the National Trust's Annual Archaeological Review for 1999-2000 mentions that a Hyperfix station at Bass Point in Cornwall was in the process of being conserved following it's closure in 2000. It also states that although the equipment is being left in situ the concrete base is all that remains of the antenna. Perhaps the National Trust doesn't want to fork out for annual inspections and repair. Or did they have no choice in the matter? Interestingly, they attribute the ownership of the site to the MoD- should this have read Racal Marine, or did the Navy have their own Hyperfix network? If so, does this explain why the site closed 5 years after those on the East Coast?! Personally I doubt it, I think it's an error in the article.

Yahoo! group for ex-Decca people :

This group has been set up to allow former employees of the Decca Navigator Co. Ltd, Decca Survey Ltd, Racal, Thales, Decca overseas branches, etc. etc., to have a point of contact for sharing stories, yarns and downright lamp-swinging about Main Chain, HIFIX, HyperFix and other now long-obsolete navigation systems. These systems ran from mid-WWII to the 1990s but were made redundant by the rise of GPS, much to our regret.
