FT8 · Native Android

Work the world
from your pocket.

FT8AF decodes the band, drives your radio over USB CAT, and runs the full auto-sequence — all natively on your Android phone or tablet. No laptop. No soundcard tangle. Just your rig and a USB-C cable.

Free & open source · GPL-3.0 · Forked from FT8CN
FT8AF Decode tab on Android: a live list of decoded stations — K7LNY, KF0X, KF6MIX, AK7LV, ND9M — each with grid square, distance, signal-strength bars, SNR in dB, time since heard, US state and a NEW DXCC pill, with Hunt / Call CQ / TX1 controls and the listening TX strip on 10.136 MHz / 30m.

Everything you need to
run a band — on a phone.

FT8, FT4 & FT2 decoding

A continuously scrolling waterfall with UTC timestamps at every period, tap-to-tune labels, and decodes in milliseconds — now across three modes.

World map & QSO paths

A built-in map tab plots every decode and draws the great-circle path to your contact — with distance, DX location, and US state borders.

Active QSO monitor & hunting

Track a contact through the full auto-sequence, with a caller queue, Hunt mode, Auto-CQ, directional-CQ awareness, and needed-DX alerts.

POTA activation mode

Run a park activation end to end — live contact list, two-fer / multi-park support, an activation map, and direct upload to POTA.

USB CAT for 75+ rigs

Drive your rig over a single USB-C cable — CAT, audio, ALC auto-leveling and SWR protection — across 75+ Icom, Yaesu, Kenwood, Xiegu and more.

Logs everywhere, automatically

The instant a QSO completes it uploads to Cloudlog, QRZ and Wavelog — and every decode you hear is spotted to PSKReporter.

Multi-language UI

Sixteen languages — from English and Spanish to Korean, Ukrainian and right-to-left Arabic — with community contributions welcome.

73 from the road

Most of FT8AF was vibe-coded on I-70 at 70 mph, heading to and from Hamvention — laptop on the passenger seat, radio in the back, Claude in the loop. Some of the best debugging happens at highway speed.
