Recently I was able to contact the operators of ZL8X, a DX-pedition to the Kermadec Islands, on four different ham bands... including 80 meters.
The islands are located about 700 miles northeast of New Zealand. A group of ham radio operators from Germany spent several weeks on these uninhabited islands.
Above is a map showing the islands (Kermadec is at the very top right of map).
At left is their on-line log showing the bands I worked them on. The photo below shows just one of several operating positions and antennas the group set up.
This was a first-class (and very expensive) ham radio operation to a part of the world that seldom has any visitors, much less ham radio activity.
