Propagation to VK9WI - Willis Is.

The TX0DX operation to the Chesterfields recently has an excellent propagation tool on their website.
TX0DX is only 545 nautical miles from Willis Island, so this tool should work reasonably well for you.

Please note:
The dates are now a month or so different. Although the smoothed sunspot number (SSN) is a little higher for our VK9WI operation, the biggest impact is due to the day/night distribution in early May compared to late March. There will be some skewing of data using the TX0DX predictions. This will be most prevalent on the lower bands (160m and 80m) and on the higher bands (15m, 12m, and 10m) due to absorption and critical frequencies, respectively. For the lower bands, use sunrise/sunset times to determine your common darkness opportunities, especially in relation to sunrise signal enhancement. In summary, when using the TX0DX data, "Your mileage may vary."
