With the help of PC4T’s tutorial I made this graphic in excel. The blue line represents my signal at Casey TI2/NA7U and the green line represents Casey’s signal at my QTH. The strange thing is that I did not receive Casey after around 01:52 UTC. But of course it could be he only listened after that time. Peak on 30m was around 02:50 UTC after that you see propagation is going up and down slowly sloping downwards. Sunset greyline at Costa Rica is at 23:20 UTC if I’m not mistaking. You see a small rise of my signal being received by Casey at that time. Casey’s signal peaked also at that time, but is difficult to see as the graphic is 3D. So I quickly made another graphic showing this. Besides WSPR on 30m I did some 10m too for 2 days, I’ve been heard in 23 DXCC now and even logged a all time new one Kazakhstan bringing me at 64 DXCC on WSPR all band.
