FT Ham vs SimpleSSTV

FT Ham – FT8/FT4 Decoder & Audio Transmitter for Amateur Radio. FT Ham puts a complete FT8 and FT4 station in your pocket. Decode, reply and log QSOs from your iPhone or iPad in real time. Decoding runs entirely on your device. WHAT FT HAM DOES - Live waterfall: color palettes, level controls and a label on every decoded signal. Tap near a signal to reply. - Real-time decoding: FT8 and FT4 from the microphone or a USB audio interface, with callsign, report, SNR and country. - Transmit: FT8 and FT4 audio for CQ, reports, RRR and 73, aligned to UTC slots and played through the speaker or your radio interface. - Auto QSO sequencing: answers CQ, follows even and odd cycles, retries when needed and logs the QSO when it is complete. - Manual control at any time: choose any message yourself. - Clear decode list: columns, an active QSO bar, NEW GRID and NEW DXCC badges and a Needed filter. - Call alerts: sound, vibration or a notification when someone calls you or a watched station is heard. - Accurate timing: slots follow network time for more reliable decodes. - Compound callsigns, optional 11 m and CB callsigns, and HF to 23 cm bands. - Logbook: edit, batch select, filter by date, undo, and ADIF import and export. - Contact map: see your logged QSOs and coverage on a map. - English, German, Spanish, French and Italian. FT HAM PREMIUM (OPTIONAL ONE-TIME PURCHASE) - CAT radio control through rigctld on your computer, with frequency sync and PTT. - QRZ Logbook, LoTW and eQSL upload with confirmation sync. - PSK Reporter spotting. - QSO statistics: charts by band and mode, DXCC counter and activity heatmaps. - iPad dashboard with the waterfall and messages side by side. Everything that was free before stays free. Premium is not a subscription. PRIVACY Your logbook and settings stay on your device. FT Ham sends anonymous crash reports and usage statistics (you can turn statistics off). QRZ, LoTW, eQSL and PSK Reporter only receive data after you turn them on. Full details at ftham.turrion.dev/privacy. GOOD TO KNOW Transmitting requires an amateur radio license. FT Ham only produces audio and your radio does the transmitting. Always follow your local regulations. The FT Ham core is open source under the MIT License. Premium features are proprietary. Third-party licenses are listed in the app.

SimpleSSTV is a native iOS app for encoding, decoding, and live-transmitting slow-scan television (SSTV) signals — the method ham radio operators use to share images over audio frequencies. Slow-scan television converts images to audio tones. Each pixel's brightness becomes a specific frequency between 1500-2300 Hz. Sync pulses at 1200 Hz mark line boundaries. The result is an audio signal you can transmit over any voice-capable radio, or record for later playback. SSTV has been used by amateur radio operators since the 1950s. It's still actively used today on HF bands, VHF repeaters, and for receiving images from the International Space Station.
