The ARRL 10m contest happens this weekend (I got the date correct this time), and as we all know, 10m can be a band full of surprises. I once again put my ZachTek WSPR desktop transmitter to work for 24 hours. Below is a snapshot from Wednesday 19:00 UTC to Thursday 19:00 UTC.
The graphs indicates that 10m becomes active around 1100 UTC, peaking at 14:00 UTC and staying decent until 21:00, when the band begins its fast closing for the day.
