Ultra-Portable F8 and FT4 Operations

iFTx is a compact iOS app (iPhone and iPad) designed to enable digital amateur radio communications using the FT8 and FT4 modes.

What iFTx Does

Portable FT8/FT4 operation: Run these popular weak‑signal digital modes entirely from your iOS device. Great for portable setups, QRP operation, field activation, Parks on the Air (POTA), Summits on the Air (SOTA), and similar 

Full contact sequencing and logging: The app handles message timing, exchanges, and stores QSOs. Logs can be exported as ADIF files for use in contest or logging software 

Simple interface: Minimalist controls—“Listen”, “Reply”, “Call”, exchange mode, waterfall view, log view, and settings screen. Easy to set up and operate in the field

The most simple setup just requires a TRX and an iOS device, no cables or interfaces (if you can stand the noise...). For other options, look here.
