Best time of day or year for LW reception

If you want to know about activity on 630m, there is a comprehensive daily report here: http://njdtechnologies.net/category/630-meter-daily-reports/

The short answer is that there is activity on WSPR, JT9, AND CW 365 days of the year... the diehard ops are there. At this time of year, considering the QRN levels, CW operations are generally early evening and as sunrise sweeps through the eastern US, centered around 474.5. I just worked a station in Texas on CW this morning, 559 both ways. Hawaii coming in overnight via WSPR. JT9 QSO with a station in Calif. two nights ago... etc, etc.

2200m has markedly less activity, mostly WSPR this time of year until QRN lowers. I have copied a VK4 station off and on throughout the summer, as recently as this morning (the latter two post-sunrise):

1040 -33 0.0 1555 ` VK4YB QG62 30 0.019
1100 -31 0.0 1555 ` VK4YB QG62 30 0.013
1110 -27 0.0 1555 ` VK4YB QG62 30 0.014

 

Summer = no good. Fall = better. Winter = best. After dark is optimal. Been doing this over 45 years.
