    Another 3000km+ opening on 144 MHz between the Canary & Madeira Islands to Italy - 11th June 2021

    Posted: 12 Jun 2021 11:25 PM PDT https://ei7gl.blogspot.com/2021/06/another-3000km-opening-on-144-mhz.html


    Friday 11th June 2021: Another day and another list of 3000km plus contacts
    on the 144 MHz band.
    First, we'll look at the reports and then the propagation mode at the end
    of the post.
    * * *
    This is the FT8 map for EA8AIN and it shows the 3000km+ path to the south
    of Italy.

    These are the paths over 3000kms...

    Each of the other EA8 stations have similar paths so I will just present
    the data that was on the PSK Reporter website.

    CT3HF was active from the Madeira Islands and the paths are shown below.

    Notice how the Sporadic-E pivots further south at the eastern end of the
    path. The path from 9H1TX was open to the Madeira Islands but not to the
    Canary Islands.CT3HF

    Propagation Mode: First, let's look at the tropo prediction map from
    Pascal, F5LEN.

    At this time of year, there seems to be pretty much a continuous maritime
    duct in the 1300km stretch of water between the Canary Islands and the
    coast of Portugal. Any European station that can reach this stretch of
    water via a single Sporadic-E hop has the potential to work down to the
    Canary Islands.
    On the 11th of June, it looks as if there was an intense Sporadic-E region
    over the north coast of Algeria and this allowed stations in the south of
    Italy to reach the duct off the west coast of Morocco.
    However, if we examine the DX Cluster, we can see one spot from EA5GJ in
    the south-east of Spain suggesting there was a Sporadic-E opening at 11:00
    UTC to the Canary Islands.

    It just highlights that while the 3000km paths from Europe to the Canary Islands are probably one Sporadic-E hop plus a tropo duct extension, there
    must be times where the path is double hop Sporadic-E even if that
    probability is lower. At the peak of the Sporadic-E season in June, I don't think we can ever be 100% sure which it is.
