SSTV Signal Desk

Decode live microphone or WAV signals, correct frequency and slant automatically, save useful partial images, and create SSTV audio for transmission.

Decode Slow Scan Television (SSTV), ham-radio and ISS signals into images, 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 and iPad: • 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 • Satellite tracking and official SSTV event sources • Portrait and landscape layouts • Localized interface in 12 languages

For amateur-radio operators, satellite listeners and anyone curious about pictures carried by sound.
