Yes I agree 100 % with you Mike.
 
Remember : in the years 1999 to 2003 there was a = lot of CW=20 activity on LF, and daytime was the best for QSO up to 800 / 1000 km. At = night,=20 only some more distant QSO can be acheived with the help of layer = reflexion as=20 OH1TN... Below about 500 km on LF the level signal stay about the same = on day or=20 night, but the noise level increase after evening, that is especially = sensible=20 on summer, so the S/N be not so good.
 
Of course, that is a bit different on the MF band = even My=20 friend F5WK at 90 km gives me about 6 to 8 db Better S/N on daytime than = on=20 night, when I am transmitting WSPR 2 on 630 m band.

Well, I think the clue is in the phrase "signal to noise". The = noise
level is much greater after dark than in the daytime, especially at =
this time of year, so for the same signal strength the S/N is = poorer
at night.
