In July 2005, G3ZAY, G0TJH, M0TDG and I went to Iceland for a week sightseeing before heading to Heimaey in the Westman Islands off the south-west coast for the IOTA contest. A write-up of the contest entry, which was an absolute disaster is available elsewhere (tnx M0TDG).
I was able to make a few QSOs from a campsite at Skaftafell on the south-east coast of Iceland one evening, but after only 12 QSOs the 4x4's car battery almost failed and we had difficulty starting the engine again, so the exercise was not repeated :)
