A weak-signal digital mode that lets a modest station pull a readable contact out of what sounds like pure static — and one of the easiest on-ramps into HF operating today.
FT8 is a digital mode built for making reliable contacts under weak-signal conditions. Where a voice contact might get lost in the noise, FT8's structured, computer-decoded signal can often still be copied — which is why it's become one of the most popular modes on the HF bands.
Your radio connects to a computer running free software (most commonly WSJT-X). The software encodes short, standardized messages — callsigns, signal reports, grid squares — into precisely timed 15-second transmissions synchronized to the clock. The software on the receiving end decodes them automatically, even well below what the human ear could pick out of the noise.
FT8 makes it realistic to work stations on the other side of the world with modest power and a simple antenna — a big draw for operators without room for a large HF setup. It's also a low-pressure way to get comfortable on HF: there's no need to talk on the air, and the exchange format is short and predictable, which makes it a popular mode for newer operators easing into HF for the first time.
