Modern Digital Modes: FT8 and JS8Call in High Latitude Propagation
2026-08-18
Recent breakthroughs in digital signal processing have transformed high frequency amateur radio communications across northern latitudes. Modern digital protocols such as FT8, FT4, and JS8Call allow hams to exchange accurate text messages and signal reports under extreme signal-to-noise ratios well below the audible threshold of the human ear. In Alaska,Continue Reading
