With the help of Derek, V51DM in Namibia I reached 100 DXCC on Greencube IO-117 only. I have no homestation, so this was either done fully battery powered from portable or with my 10 ele Alaskan Arrow antenna handheld.

The project is coordinated by the Italian Space Agency (ASI) and took advantage of a launch opportunity offered by ESA.
