ZL100AC New Zealand
On 22 May 1924 Ivan O'Meara (2AC) in Gisborne, New Zealand made the first trans-Pacific contact with Carlos Braggio (CB8) near Buenos Aires, Argentina on 130 metres, setting a world record distance of just over 10,000 km. To commemorate this historic milestone, the Gisborne Branch of the New Zealand Association of Radio Transmitters (NZART) will be using the special callsign ZL100AC throughout the month of May.
