There was an extensive Sporadic-E opening across Europe on Monday the 18th of May 2020 with strong signals being reported on all the VHF bands from 28 MHz to 70 MHz. This is a report on some of the activity on the new 40 MHz band.
1) 40 MHz Crossband contacts - Tim EI4GNB reports working crossband from 40 MHz to 28 MHz with DJ3AK (JO52GJ) at 11:22 UTC and OE3FVU (JN78VE) at 11:28 UTC. All contacts were on FT8.
The distances were roughly 1200 kms and 1700 kms respectively. Tim was also busy making more crossband contacts from the 60 MHz band, I'll put that in a separate report.
2) Irish 40 MHz EI1KNH Beacon - At least three stations reported reception of the Irish EI1KNH beacon on 40.013 MHz.
a) Gintas LY2YR (KO24OS) managed to get four successful decodes of the beacon using the PI4 software.
40M 11:45 UTC EI1KNH PI4: S/N=-19 dB Q=46 T=0,40 s F=50 Hz Carrier: F=851,6 Hz C/N=-17 dB
40M 11:46 UTC EI1KNH PI4: S/N=-19 dB Q=60 T=0,35 s F=50 Hz Carrier: F=851,6 Hz C/N=-23 dB
40M 11:50 UTC EI1KNH PI4: S/N=-20 dB Q=36 T=0,37 s F=55 Hz Carrier: F=852,4 Hz C/N=-19 dB
40M 11:52 UTC EI1KNH PI4: S/N=-19 dB Q=20 T=0,40 s F=55 Hz Carrier: F=852,5 Hz C/N=-31 dB
The signal was quite weak at -19dB to -20dB which is understandable considering the distance is over 2,000kms.
b) Andreas DJ5AR in Germany got six successful PI4 decodes with the signal going from =1dB to -12 dB.
c) Tom SP5MXU in Poland also reports reception of the beacon with an ICOM IC7300 and a 5 element beam for 50 MHz...

3) Danish 40 MHz OZ7IGY Beacon - There were two reports of the beacon on the DX Cluster.
a) Michael EI3GYB reported reception of the OZ7IGY beacon on 40.071 MHz at 12:19 UTC.
b) And finally EI7GL! I managed to hear the Danish beacon in two separate openings. The first one I caught was roughly from 13:03 UTC to 13:54 UTC with the second shorter opening from 17:42 to 17:51 UTC.
There may have been more openings of course but this is what I heard.
