The reports shown above are from Chris Arnold, N3IZN in California who heard the WPSR transmissions on 144 MHz from the KH6HME beacon on a mountain in Hawaii.

The tropo duct across the eastern Pacific usually opens up several times a year and allow signals from 144 MHz to the microwave bands to propagate through it. It's probably one of the best long distance VHF paths in the world.
