Bob F Posted February 20, 2005 Report Share Posted February 20, 2005 Anyone know the name of the Decca Chains (lanes) that are used in the south of England? Are they still in use?? cheers BF Quote Link to comment Share on other sites More sharing options...
Adam F Posted February 20, 2005 Report Share Posted February 20, 2005 Dont know much about Decca, but a quick search of the WWW shows up some interesting info. Didnt know that it used Low frequency radio waves to plot a position...anyway to answer your question, No they are not in use any longer. Decca ceased at midnight on the 31st March 2000.

toerag Posted November 8, 2005 Report Share Posted November 8, 2005 The Southwest 1B chain had transmitters in Cornwall, Jersey & Portland, I don't know about further east. If you can get hold of an old Decca chart then it should have the chain info on it. Once you know the chain info, then you can use the 'Decca 1.0.1' program downloadable on the internet to convert the decca positions in the wrecklist you've acquired (I assume this is what you want the info for) into Lat & Long. If you've got a wrecklist without the colour infomation on it then the help files in decca 1.0.1 will explain how the lane numbering is colour specific. Alternatively some plotters do decca conversions. My Garmin only does Loran C conversions. Quote Link to comment Share on other sites More sharing options...
