Bands & Modes

Every amateur band behaves differently. 160 and 80 metres come alive after dark, 40 metres carries traffic around the clock, 20 metres is the workhorse for daytime DX, and the bands from 17 to 10 metres open wide when the solar cycle is strong. Knowing which band is likely to be open — and how people use it — saves hours of calling into empty spectrum.

The mode matters as much as the band. SSB is the voice mode of HF, CW still punches through when nothing else will, and digital modes such as FT8 work signals far below the noise. Each has its own etiquette, frequency segments and techniques for being heard.

These guides cover the practical side: reading the bands, avoiding the classic newcomer mistakes, learning Morse code, getting clean and punchy SSB audio and fighting the noise that masks weak signals.
