Very weak Sp-E opening on 28 MHz - 19th April 2021

The Sporadic-E opening on the 19th of April 2021 was a pretty weak affair with just 22 stations in 8 countries heard on 28 MHz. It's hard to claim that the band was open for 5 days in a row as this one was so weak.

One interesting signal was R7AZ at 3660 kms. Double hop Sporadic-E or one hop F2? On 10-metres, it's sometimes impossible to tell.
