I have been on 30m WSPR a lot when VK0EK was on from Heard Island and actually hoped for some spots. But unfortunateley VK0EK has been spotted only by a few in Europe. I even came to the point that I mailed via DXA to find out if the WSPR beacon was still on (after a few days without any spot activity at all). I don't know what the antenna was they used but if you spotted the beacon you got a very very good receiver/antenna and low noise I guess. I was not a bad listener on 30m WSPR (high in the list at PE1ITR WSPR challenge page) with my horizontal loop but I missed the VK0EK WSPR signal. The only one that received VK0EK when on Heard Isl. from the Netherlands was PI4THT from the University of Twente.
A little late I thought of the WSPR map that can be created online. So I miss some spots I guess. May be someone else has the complete list of unique stations that spotted VK0EK? Anyway, it's still interesting. It's also interesting that the beacon is still on now while the DXpedition crew is returning at the ship (MV Braveheart) signing as VK0EK from several different grids from were the ship is at the moment.However, I have no illusion receiving them with my vertical since the loop isn't up anymore.
