My research into locating Second World War direction-finding stations has been ongoing for a few years now. However, after back and forward emails with author and historian Ian Brown, I think we now know much more about these sites. One of the main aims of this research was to locate and plot these sites. There are still some gaps in our knowledge, and while we have almost definitively been able to list all of the H.F.D.F. and V.H.F. fixer stations from the archive records, there are still some remaining structures that don’t appear to fit into either list. To help further this research, I have published all of my known information to date below.
