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 […]

By Mike, W6MVM Hi, the first question is “Is CW dead?!?”. Code is no longer required to get a license. Does anybody still use it? It was dropped from the requirements because the military no longer needs trained operators. For many years it was thought essential for national defense to have trained Morse Code operators, but not in the age of digital communications. But is it dead? Not hardly. As I’m writing this column, I’m tuned to the 20 meter band. Looking at the lower CW portion with my Flex 6300. The spectrum is set to cover the whole CW area […]
