- Back in my Novice-Tech days, I used 10M SSB only. I got to know that band's propagation characteristics pretty well. From the east coast USA... Africa early morning, Europe mid-morning, Caribbean early afternoon, west coast North American mid-day to evening. Japan early evening to darkness, Australia late evening. Pretty much and compass circle from east to west over 12-15 hours ,. What about 30M? I have not been on it much of late. Any predictable path ?
