Some years ago, the local gov department (fcc to you) here in aus carried
out test on their hf df. They were able to pinpoint a station in soth
australia within about 1 km or so. Impressive I thought at the time.

In WWII the allies were able to pinpoint the locations of German HF
transmissions very accurately. They were able to pinpoint the
locations of U-boats, etc. when they transmitted. (or so I have been
led to believe).

What methods did they use to do this? Is it something duplicatable
with Radio Amateurs in general or does it require some special type
equipment?


I hear lots of amateurs describing interference and other problems on
HF, but no one seems to be triangulating the offending stations. I am
guessing that the real secret was in their communications with the
'spotters' to triangulate the positions.

Any suggestions?

Thanks
