Robot72 - ISS SSTV Decoder

Robot72 turns pictures into slow-scan television (SSTV) audio, and SSTV audio back into pictures. Decode images from ham radio, from the International Space Station or from a friend's phone, and send your own photos to any SSTV receiver. RECEIVE Tap Listen and hold your iPhone near the radio's speaker. Robot72 reads the VIS header, picks the mode and draws the picture line by line. To decode a WAV recording, tap File. Reception keeps going when the screen is locked, with progress in a Live Activity. SEND Pick a photo, choose the mode your contact uses, add a caption if you like, and play it through the speaker or a cable into your radio. Pro also exports the audio as a WAV file. ISS PASSES Enter your location or use the current one, and Robot72 lists ISS passes for the next 48 hours with peak elevation and direction. Turn on reminders to get a notification a few minutes before each pass. Predictions are calculated on your iPhone from CelesTrak orbital data; your location is not uploaded. 31 MODES Robot 8/12/24/36 BW, Robot 12/24/36/72 Color, PD 50/90/120/160/180/240/290, Martin 1–4, Scottie 1/2/3/4/DX, Wraase SC2 30/60/120/180, Pasokon P3/P5/P7.
