SSTV Signal Desk

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

Share received images as cards with saved reception details and optional callsign and grid locator.
