    Back in April of 2021, there was an opening on 144 MHz between Hawaii and California, a distance of approximately 4074 kms.

    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.

    28 MHz Report for Sun 9th May 2021

    Sunday 9th May 2021: While the 9th didn't seem to be as good as the 7th &
    8th, there were still lots of Sporadic-E signals on 28 MHz for most of the
    day. Again, I spent most of the day on WSPR with the receive map for me
    shown above.
    This time, I heard 7 stations running 50mW or less.(y-m-d) TX txGrid RX

    When the skip went short, I managed to get two QRSS (very slow morse) plots from two stations east of London, about 600kms from me.

    I also spent some time monitoring the FT8 frequency and I heard 279
    stations in 36 countries.
