During an extensive Sporadic-E opening on the 12th of January 2021, Tim EI4GNB near Dublin, Ireland completed a successful FT8 contact with Dragan 9A6W in Croatia, the first EI-9A contact on the new 8-metre band.
The FT8 contact was completed on 40.680 MHz which is in the middle of the 40 MHz ISM band (Industrial, Scientific, Medical).
As the screenshots above from 9A6W, the signals were quite weak.
The screenshot below shows how EI4GNB was not only hearing 9A6W in Croatia on 40 MHz but also S59F and S50B.
This is a map of the contacts for EI4GNB from PSK Reporter...
The contact between EI4GNB and 9A6W was in the region of 1,974 kms which is a standard distance for single hop Sporadic-E.
40 MHz activity... It was also great to see that a number of stations were listening on the 40 MHz band today. These are the stations that heard S59F on 40.680 MHz on the 12th of January 2021...
