Another Sporadic-E opening on 28 MHz for the 4th day in a row - 18th April 2021

Sunday 18th April 2021: The 28 MHz band opened for the 4th day in a row with a modest Sporadic-E opening to the south of Spain and Scandinavia. 

Most of the signals from Spain were slightly long at 1600-1700kms with nothing coming from the centre of the country.

The opening to Scandinavia was unusual in that it was the first Sporadic-E opening in that direction this year. The FT8 signals were strong enough that it prompted me to do a few scans and I heard two beacons.

EI7GL 28237.4 LA5TEN/B 12:25 18 Apr IO51TU<ES>JO59JP Norway

The LA5TEN beacon near Oslo is also probably one of the most consistent signals that I hear from Scandinavia so it was no real suprise to hear it first.

As the map shows above, there was some weak F2 propagation to South Africa and Brazil. 

For some reason, some of the 10m spots showed up as Grey but they were all on 28 MHz as that was the only band I monitored. Overall, I heard 93 stations in 18 countries on FT8.

The Solar Flux was at 75.
