The maximum period of operation will be three hours (6 operating periods of 30 minutes each).' Times are stated in UTC, so unlike the Jock White Field Day this record is not wall-clock. Band: '80m'. Power as quoted in note. Exchange as quoted. Log deadline: 'on or before the fourth Saturday after the contest', which is exactly the stored end instant plus 28 days, so the interval is encoded; logs go to sangster@nzart.org.nz. Checked against the date NZART prints on the same page: 'The next Sangster Shield contest will be held on Saturday 16th May 2026', and the third Saturday of May 2026 is May 16."
