I am delighted to report that I have worked TX5K, Clipperton Island. I managed to nab them after about 20 minutes of trying on Sunday on 17 metres CW. They had a big signal, but of course the European pile-up was huge. I had tried for ten minutes before dinner but didn't get through. Immediately after dinner I was back at the rig again and figured out his listening pattern. After about ten minutes I heard the magic "EI2KC 5NN" coming through, and confirmed the QSO with "RR EI2KC 5NN TU".
TX5K is an international dxpedition to Clipperton Island (official DXCC designator FO-C). It's my 285th DXCC worked. I am particularly delighted because tomorrow, Tuesday, will be the third anniversary of receiving my EI2KC callsign.
