http://dx-world.net/2012/zl9hr-campbell-island-dxpedition/ . This reminds me of the excellent conditions on 20m AM back in the 1960s when I remember hearing a station on Campbell Island working the UK with S9 signals early one morning. In those days I'm sure the prefix was ZL4 though.
Is it just me, or is it much more difficult to hear and work DX stations these days compared with back then? Some believe that the ionosphere has actually deteriorated in the last 40 odd years so that, despite rising sunspot numbers, conditions are not as good as they were years ago.
