Just switched on the radio yesterday evening for some fun on the new acquired 60m band. A big signal came in from OY1R/MM. Wow, 9+30dB! I suspected he was in the "Eemshaven" harbour nearby. And indeed Regin confirmed he was on a vessel just arriving in the harbour. That's about 3-4km from my QTH. We had a very pleasant QSO and he told me he was on the bridge working with the ship's Sailor radio and 150W. Antenna was a vertical with autotuner. I asked Regin why he did not sign PA/OY1R/MM as he was in the Netherlands. Regin told me there was no need for that as a Maritime Mobile station does not count for DXCC. He always use his homecall regardless in which country he is with the ship.
