144 MHz beacon on St Helena heard in Namibia over 2250km sea path

Back in February of 2021, I had a post up about the new 144 MHz on St
Helena Island in the South Atlantic. On the 3rd of March, I reported that
the beacon had been heard over 3000kms away in South Africa.
On the 9th of March 2021, the 144 MHz beacon was heard by David, V51DK on
the west coast of Namibia over a 2253 km sea path.

V51DK who is located in the city of Swakopund has a very modest station and
was just using a Diamond X200 vertical antenna at just 6-metres above
ground level.
As the tropo forecast from F5LEN shows below, there were excellent
conditions between St Helena and Namibia.
This form of maritime ducting is a regular occurrence is this part of the
South Atlantic Ocean.
