FT Ham – FT8/FT4 Decoder & Audio Transmitter for Amateur Radio

FT Ham puts a complete FT8/FT4 decoder and audio encoder/transmitter in your pocket. Decode, reply, and log QSOs directly from your iPhone — all in real time, fully offline.

What the app does for you:

• Live Waterfall: frequency vs time spectrogram with color intensity and vertical labels for each decoded signal.
• Real-time Decoding: receive FT8 and FT4 audio via microphone or connected audio interface and see callsigns, reports, and SNR instantly.
• Transmit (Encode & Play): generate FT8/FT4 audio for CQ, reports, RRR, and 73, aligned to correct UTC slots and played through speaker or radio interface.
• Auto QSO Sequencing: detects CQ, prepares replies, respects UTC timing and even/odd cycles, retries if needed, and can complete QSOs automatically.
• Manual Control Always Available: full manual message selection and intervention at any point.
• Predefined Messages & Composer: CQ, DX→ME, reports, RRR, and 73 — automatically filled with your callsign and locator, fully customizable.
• Logbook & ADIF Export: automatically log completed QSOs and export to standard ADIF for external logging software.
• Contact Map: visualize logged QSOs and geographic coverage in a single view.
