By David McNeil W6PHO We are now entering the “Solar Maximum” part of Solar Cycle 25, which could mean four years of excellent conditions for DXing. Maximum solar activity increases ionization in the “F” region of the ionosphere (150-250 miles up) which facilitates daytime 20 to10-meter propagation and nighttime 40 through 10-meter propagation. If you’re wondering when to look for DX, the SN (Sunspot Number) may help. While the SN is the result of observation and calculation with some tricky statistics thrown in (for a “smoothed” number), it is often a good indicator of conditions for DXing. The highest SN count […]
