If you’ve been on the HF bands in recent years, you’ve probably seen or heard the buzz around FT8. Whether you’re a seasoned operator or just earned your ticket, FT8 is hard to ignore — and for good reason. This digital mode has revolutionized the amateur radio scene, making long-distance contacts easier than ever, even under poor band conditions.
So, what is FT8 all about?
What is FT8?
FT8 stands for Franke-Taylor 8-tone, named after its creators Joe Taylor (K1JT) and Steve Franke (K9AN). It’s a digital communication mode designed for weak signal communication on HF and VHF bands. It’s part of the WSJT-X suite of digital modes, which are specifically tailored for making reliable contacts when signals are barely audible or even completely inaudible to the human ear.
FT8 uses eight tones (hence the “8”) and a tight, synchronized transmission and decoding schedule. Each FT8 transmission lasts just 15 seconds, with 12.64 seconds of actual signal and the rest reserved for decoding and timing. The result? A highly efficient mode that can decode signals 20 dB or more below the noise floor.
Why is FT8 So Popular?
FT8 has gained immense popularity for several key reasons:
-
Works When Nothing Else Does: FT8 excels in low-signal, high-noise environments. You can work DX on a modest setup with low power and a wire antenna.
-
Automation-Friendly: While not fully “set-and-forget,” FT8 lends itself well to semi-automated operation. With WSJT-X and optional add-ons like JTDX, GridTracker, or even logging integrations, many operators use FT8 to rack up contacts with minimal interaction.
-
Great for Awards: Because it’s so effective at making quick contacts, FT8 is a popular mode for chasing DXCC, Worked All States, and other awards. You can often work multiple new entities in a single evening.
-
Low Power, Low Stress: With many operators running 5 to 30 watts, FT8 is a QRP-friendly mode that’s gentle on your rig and easy on your electricity bill.
How Does FT8 Work?
FT8 transmissions are time-synchronized and take place in 15-second intervals. That means your computer’s clock must be accurate — typically within a second. Tools like Dimension 4 or Meinberg NTP help keep your PC time in sync.
Each FT8 message is 75 bits long, containing your callsign, the other station’s callsign, your signal report, and your grid square (or a reply like “RR73” to acknowledge receipt). Despite the limited message size, it’s enough to complete a full QSO — and because FT8 is designed for efficiency, you can do so in just a minute or two.
What Do You Need to Get Started?
Getting on the air with FT8 is easier than you might think. Here’s what you need:
-
HF or VHF/UHF transceiver with SSB capability
-
Computer with a sound card interface (many modern rigs have one built in)
-
WSJT-X software (free)
-
Accurate time synchronization software
-
Optional logging/visualization tools like GridTracker or Log4OM
You’ll connect your radio to your computer via USB or a dedicated interface (like a Signalink), fire up WSJT-X, choose FT8, and tune to one of the standard FT8 frequencies (like 14.074 MHz for 20 meters).
FT8: A Mode for Everyone
Some hams argue that FT8 lacks the “soul” of traditional ragchewing — and sure, if you’re into long, conversational QSOs, FT8 isn’t the mode for that. But as a tool for making global contacts with minimal power and setup, FT8 is unmatched. It’s also brought a whole new group of hams into the hobby — including those who enjoy the technical, data-driven side of radio.
Whether you’re using it to test a new antenna, fill in those last few states, or just enjoy the quiet thrill of watching your signal get picked up halfway around the world, FT8 is worth exploring.
