W8S: PROPAGATION PREDICTION CHART
Jari, OH6BG has prepared a propagation prediction chart for W8S, the 4-17 October DXpedition to Swains Island. "The timeframe in October as well as the antennas and power that will be used on Swains are set by default, so you only have to put your grid square and antenna situation in the designated boxes and the chart will show you the best bands and times to make it into our log":
