I generated these images using the free program “HamCap” by VE3NEA.  I enhanced  the images using PaintShop Pro.  These images show expected February propagation from Thunder Bay using 100 watts power, dipole to yagi, with antennas at 35 feet high.

20 METER BAND

This band requires sunlight to enable propagation.  Note how the band goes dead at night.  The propagation is eastward at sunrise and westward at sunset.  Note how these is a dead area within a few hundred miles, because the radio waves are skipping high over nearby areas.  This band is used for worldwide communication during daylight hours.  It is not suitable for short distances.
