    Opening on 50 MHz between Europe and SE Australia - 13th July 2021

    Posted: 13 Jul 2021 10:11 AM PDT https://ei7gl.blogspot.com/2021/07/opening-on-50-mhz-between-europe-and-se.html


    13th July 2021: There was yet another opening on the 50 MHz band between Australia and Europe. In contrast to other openings, this one was a bit
    unusual in that it seemed to be largely confined to the state of Victoria
    in the SE of Australia.
    These are the spots from the DX cluster which seems to suggest that once
    again, all of the activity was on FT8...

    VK3OT-@ 50313.0 UR0MC 05:43 13 Jul Into Qf12 Qf22 Ukraine
    50 MHz paths from DK8NE were confined to the state of Victoria
    It's interesting to note that the opening seemed to have a one-hour window lasting roughly from 05:15 to 06:15 UTC. Local sunset in Victoria was at
    07:12 UTC.
    The longest path that I could find was from VK3DUT in Victoria to F4HMQ
    near Paris in France, a distance of almost 17,000kms.
    These are the FT8 reports from the PSK Reporter website...

    3000km+ opening from the Canary Islands to Germany - 8th July 2021

    Posted: 12 Jul 2021 11:11 PM PDT https://ei7gl.blogspot.com/2021/07/3000km-opening-from-canary-islands-to.html



    On the 8th of July 2021, there was another example of a 3000km+ path on 144
    MHz between the Canary Islands and Germany. As can be seen from the map
    above and the DX Cluster spots below, both DK5AI and DL8DAU in German
    managed to complete a digital FT8 contact with EA8JK.

    DL8DAU-@ 144174.0 EA8JK 15:00 08 Jul JO40<ES>IL18 -20/+6 tnx! Canary Islands DK5AI 144174.0 EA8JK 14:59 08 Jul JO51GO<ES>IL18 Thanks 73! Canary Islands
    The distances were 3674kms for DK5AI and 3287kms for DL8DAU.
    Update: Frank, PA4EME in JO20WX also reports reception of EA8JK as well. Propagation Mode: It would seem to be another example of a combined
    Sporadic-E and tropo ducting path. The tropo prediction map below from
    F5LEN shows the presence of a maritime duct between the Canary Islands and
    the south-west coast of the Iberian Peninsula.

    It's likely that this tropo duct accounted for 1000-1300kms of the total
    path. The rest was due to a short Sporadic-E opening from Germany which
    coupled into the NE end of the duct.
    There is also the possibility that it was double hop Sporadic-E but the probability of this is a lot lower than a combined tropo/Sp-E path.
    More examples of 3000km+ openings can be seen on my 144 MHz page.
