Live band decoding & waterfall
A continuously scrolling waterfall with UTC timestamps at every FT8 period, tap-to-tune labels, and decodes in milliseconds.
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.
