qFT8

Decode and send FT8, FT4, JS8, WSPR, CW, RTTY, SSTV and more through your radio's audio, or control your radio through a qFT8 bridge on your computer.

qFT8 turns an iPhone or iPad into a digital-mode station for licensed radio amateurs.

MODES: FT8, FT4, FT2, LQ8, JS8, WSPR, Morse (CW), RTTY, SSTV pictures, and voice (SSB).

HOW IT CONNECTS TO YOUR RADIO

• Audio: connect the radio's USB sound interface (or an audio cable). qFT8 listens to the radio and sends its tones to it; the radio switches to transmit by itself (VOX).
• No CAT on iPhone and iPad: iOS and iPadOS do not let apps control a radio over a USB cable (CAT), so you set the frequency, mode and power on the radio itself.
• qFT8 bridge: plug the radio into a computer on the same Wi-Fi and run the free qFT8 program there as a bridge. Then the iPhone controls the radio too (frequency, mode, transmit) and gets its audio over Wi-Fi.

ON THE AIR

• Waterfall and decoded messages, automatic QSO sequencing that runs only while you have TX on.
• Your log, with ADIF export and import, and optional uploads to the services you use (QRZ, LoTW, eQSL, POTA and more).
• Map of the stations you hear, band activity, POTA and SOTA activations.
• Transmit is off until you press TX ON. qFT8 never changes your radio's power.

On a Mac, use qFT8 for Mac (Mac App Store): it controls 70+ radios over USB (CAT).

No account, no ads, no tracking. You need an amateur radio licence to transmit.
