SSTV Signal Desk
方宇 周
Decode SSTV and Weather Fax signals into images, receive ISS SSTV transmissions, or turn your own pictures into transmit-ready audio. Receive live signals through the microphone or decode supported audio files. SSTV monitors the spectrum, adjusts frequency and slant, and lets you keep useful partial decodes when a transmission ends early. Prepare and transmit images in a broad range of Martin, Scottie, Robot, PD, Pasokon, monochrome, FAX and AVT modes. Save decoded images and generated WAV files in clear RX/TX archives. Built for iPhone, iPad and Mac: • Guided Simple and Advanced modes • Station profile and QSO logbook • Private iCloud sync across devices and editions • Professional Signal Desk with live spectrum • On-device decoding and encoding • Automatic frequency and slant correction • Partial-image saving for useful incomplete decodes • Mode guide with timing and resolution details • Receive and transmit history • Doppler-aware satellite tracking, pass reminders and provider-aware tuning • SSDV and advanced digital image reception, callsign overlays, FSK/CW IDs, templates and automation • Portrait and landscape layouts • Localized interface in 12 languages Share received images as cards with saved reception details and optional callsign and grid locator. For amateur-radio operators, satellite listeners and anyone curious about pictures carried by sound.
