    5000km+ paths on 144 MHz recorded in South America as the TEP season begins
    - 20th Sept 2021

    It was interesting to note that there were several openings over the last
    few days on 144 MHz between the Caribbean and South America.

    The map above shows the 5155km path that was open on 144 MHz between Aruba
    and Argentina.
    P41E 144300 LU8FLB 00:59 20 Sep 21 Tep Argentina
    The DX spot was most likely for a SSB signal and the propagation mode was
    TEP or Trans-Equatorial Propagation.At around the same time, the path was
    open for FG4SU in Guadeloupe to the south of Brazil.


    These are the FT8 spots...
    20th Sep
    Txmtr Rcvr Band Mode Distance Time (UTC)
    FG4SU PY2OAL 2m FT8 4566 km 01:04:59
    PY2BL FG4SU 2m FT8 4649 km 00:27:44
    Notice how the signals from the two locations are different. At 144 MHz,
    only signals that cross the Geomagnetic Equator at right angles tend to get propagated via TEP. What this means is that stations near Aruba work
    Argentina while stations further east in Puerto Rico work the south of
    Brazil.
    While I was looking up some information for this post, I noticed that there were also TEP openings on 144 MHz on the 17th and 19th of September.

    It's likely there are going to be plenty of more openings between the
    Caribbean and South America on 144 MHz over the next few weeks. It would be interesting to see some reports of similar openings from the south of
    Europe to Africa.
