I know DX occurs because of athomspheric conditions & tends to occur the most in late spring & summer, especially when its warm & humid. I have noticed DX much more at night ( from about 9 or so till dawn) than I do during the afternoon (although I have caught DX on quite a few occasions then as well). Is their any reason why DX is stronger/ occurs more often at night or is it just coicidnece??
