Visualization of shortwave propagation by HF-START. The radio wave propagation paths at 3, 6 and 9 MHz transmitted from Tokyo to Hokkaido, and from Tokyo to Kagoshima are shown. The radio propagation at 12 MHz is also calculated, but is not displayed because the 12 MHz does not reach the destination.
