South African 8-metre beacon on 40.675 MHz heard in SE England - 13th July 2021

On the 13th of July, there was a good opening on the 50 MHz band from Europe to South Africa. During this opening at about 13:50 UTC, Paul G7PUV in the south-east of England managed to hear the South African 8m beacon ZS6WAB/B on 40.675 MHz.

This beacon was heard in the Mediterranean area several times during the month of April 2021 and this is the first time that it has been heard so far north. The distance is around 8,800kms.

For the reception, Paul was using a custom made W4KMA Log-Periodic antenna covering 26-100 MHz at 15-metres above ground level.

Paul reports that the beacon which transmits only on CW peaked at S2.

Propagation Mode: It's probably one of two options.

a) Multi-hop Sporadic-E which would require 4-5 hops and crossing the equator to the southern hemisphere where it's their winter season.

b) A combined TEP (Trans-Equatorial Propagation) and Sporadic-E opening. TEP from South Africa to the Mediterranean area and then via a Sporadic-E hop from there to England.

I suspect it may have been TEP + Sp-E even though we are not near the Equinox and the peak of the TEP season.

Info: For more information of the ZS6WAB beacon and previous reception reports, see my 40 MHz page.
