    EA8CXN completes 1296 MHz contact by bouncing a signal off a cruise ship -

    I recently read an interesting post on the website of César, EA8CXN about
    a 'Ship Scatter' contact on 1296 MHz (23cms)!
    The map above shows the scenario. EA8CXN and EA8CSB are on the island of Tenerife in the Canary Islands and they cannot complete a contact directly
    on 1296 MHz due to local mountains.
    They did however manage to complete a contact by bouncing the 23cm
    microwave signals off a passing cruise ship which is about 60kms away!
    Amazing.
    After initially completing a contact on FT8, they managed to complete a QSO
    on SSB.
    EA8CXN was running 100 watts in a 1-metre dish with horizontal
    polarization. EA8CSB was using just 2.5 watts into a vertical Diamond
    X-7000.
    Check out the post on EA8CXN's website for more info and to see the SSB contacts.

    Quiet day on 28 MHz - Sun 25th Apr 2021

    Posted: 25 Apr 2021 10:54 PM PDT https://ei7gl.blogspot.com/2021/04/quiet-day-on-28-mhz-sun-25th-apr-2021.html





    Sunday 25th April 2021: This was a pretty quiet day on the 28 MHz band with
    20 stations in 9 countries heard on FT8. The poor conditions may well have
    been due to some geomagnetic disturbance from the sun.
    The one unusual Sporadic-E opening was to Portugal with 7 stations heard
    from a very small geographic area.
    The other unusual signals for me are those from the UK...Txmtr Band Mode
    Distance Time (UTC)
    G0DLV 10m FT8 288 km 10:23:59
    GI4SNA 10m FT8 334 km 20:25:29
    MM0IMC 10m FT8 488 km 11:15:00
    G0OYQ 10m FT8 579 km 09:03:44
    MM3NRX 10m FT8 620 km 07:57:59
    I think the first two are probably via tropo but I'm not sure about the
    signals that are 500kms and above.
    For example, I seem to hear G0OYQ near Hull nearly every day. I suspect it
    may be via meteor scatter and FT8 is digging out signals that are buried in
    the noise. How to prove it is another matter.
