FT Ham vs SimpleFT8

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. Privacy & Safety: - All decoding and signal processing runs entirely on your device. No internet connection required. - FT Ham does not collect or share personal data. All settings and logs remain local on your device. - Audio output may be connected to external radios; always comply with local amateur radio regulations. - Payments are handled by Apple or third-party services; FT Ham never receives payment details. Legal & Licenses: - FT Ham code is released under the MIT License. - Third-party library licenses are included in-app.

SimpleFT8 is a native macOS and iOS app for FT8 and FT4, the weak-signal digital modes used by amateur radio operators worldwide. WHAT IS FT8? FT8 is a structured digital mode for ham radio. Stations alternate transmitting and receiving in synchronized 15-second slots, exchanging compact messages over a narrow audio bandwidth. The mode decodes successfully at signal levels well below the noise floor — operators routinely make contacts on a watt or two of power with stations on the other side of the planet. SimpleFT8 puts a real digital station in your pocket. Decode signals using your device's microphone or a USB audio interface and send replies in the next slot. The manual station and local logbook work without an account. WHAT YOU GET • Live decode table per 15-second FT8 or 7.5-second FT4 slot • Slot-aligned transmitter with a structured QSO composer (CQ / reply / report / RR73 / 73) • Tap any decode to start a QSO — the state machine handles the rest of the handshake • Built-in waterfall display with tap-to-set TX frequency • Local QSO logbook with search, editing, ADIF import/export, and complete native backup/restore • Map of stations you've decoded with their Maidenhead grids SIMPLEFT8 FREE Free includes unlimited FT8/FT4 receive, waterfall and decode history; microphone and USB audio; manual CQ, reply and complete QSO exchanges; all TX safety controls; local logging and full portable ADIF import/export; and the basic community map. SIMPLEFT8 PRO — ONE-TIME LIFETIME UNLOCK Pro adds automatic replies, custom-message looping, CAT/PTT rig control, macOS System Audio capture, autonomous band hopping, advanced export scopes, direct QRZ Logbook transfer, and private iCloud log sync. No subscription. Customers who bought SimpleFT8 before it became Free receive Pro automatically. PSK REPORTER + PRESENCE (OPT-IN) If you turn it on in Settings: • Decode reports forwarded to PSK Reporter so you contribute to the global propagation map (rate-limited server-side) • See who heard you in the last 15 minutes, plotted on the map • See other SimpleFT8 operators currently online, on the same map Both toggles are off by default. QRZ transfer and private iCloud log sync are also separately configured and off by default. WHAT MAKES IT DIFFERENT • Native Swift/SwiftUI — no Electron, no Qt port. Looks and feels like a Mac/iOS app should. • Pro System Audio capture on macOS via ScreenCaptureKit — decode straight from SDR software, WebSDR, or any audio your machine is playing, without a virtual cable. • Random caller selection rather than first-come — every station in a pile-up has an equal shot at being picked. • Opinionated QSO state machine handles slot parity, role alternation, and protocol step transitions so you don't have to fight the radio. PRIVACY The app is foreground-only on iOS — the mic stops when the app goes to background. macOS keeps audio I/O alive (long FT8 sessions are the norm). Optional community and logbook integrations are clearly opt-in. No analytics, no tracking, no ads, and no subscription. Built by a ham operator for ham operators. 73 de PD3BAL.
