    Re: Small craft RDF in 1967

    Thanks Greg,

    Very interesting. Seems they mainly relied on sextant meridian sights though? No mention of LOPs or time sights. Not sure how accurate their longitude would have been? Running down a radio station bearing without accurate  longitude could have given interesting results! On the rock strewn Scillies,if poor visibility,  I would use the RDF signal bearing, go about and run away from it!

    I've recently had a bit of fun with my old (1980s) Lokata 7 RDF. Can locate my garden with a fix from 2 local airport NDBs. When (if) I go down to the sea again (in my not very tall ship!) I should be able to find Ireland anyway, by running down RTE radio 1 on 252KHz. Sadly the only long wave station I can find. The NDBs from local  airports are all short range and as Gary suggests, not much used by aviators and therefore disappearing fast.

    Halcion days!
