Some of the best times for listening, when nobody is awake, is 3-4am :-) 
My first CW by the ear reception of Louisiana Ralph's signal when he 
lived in town was just before sunrise. That was from the early days when 
Ken was the admin for the SHMRG license.

That number seems to jive pretty well with the levels for "easy" CW copy with headphones as assessed with many CW QSO's with XJM over the past 16 months.  Its kind of a crap shoot below -8/-10 and seems to depend on the operators willingness to dig through the noise and what filtering is available.

Thats not to say the earlier signals are not workable because they are but going east there seems to be a peak later in the night/earlier in the morning..  Its too bad I don't wake up more in the middle of the night with the willingness to operate HI!
