SSTV Signal Desk
Ham Radio Decoder & Encoder
$2.99 · Designed for iPad
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.
