About this app

Following SSTV modes are supported:

Robot Modes: 36 & 72
PD Modes: 50, 90, 120, 160, 180 & 240
Martin Modes: 1 & 2
Scottie Modes: 1, 2 & DX

Old B/W or unsupported modes can be viewed in "Raw" mode.

On detection of the calibration header of a supported mode, the resulting image will be automatically saved to the "Pictures" directory and can be seen in the Image gallery.

With version 2, running the decoder in the background will not be supported anymore.

Ratings and reviews

Hey Ahmet, this app works really well at decoding, and that's without using a HAM radio and just playing back SSTV audio from YouTube. One note, and this doesn't affect the rating: it seems like Scottie DX peaks out the microphone and causes the app to switch to RAW for second intervals, which causes cyan-line artifacting that prevents images in that format from saving. Not your fault though, just a side effect of my mic being just OK. Everything else works great though!

It wasn't designed to do phone calls. Amazing how the decoder can automatically select format. Creates interesting effects when the encoder is played through an amplifier. Would like to try this in a large reverberation sized room. Working best when at lower volume not loud enough to bounce off of walls. Scottie DX is actually the only mode that doesn't smear my profile picture. I've got this encoder and decoder set on 3 of my devices. I've sent my profile picture to myself through every single mode this pair can do. Looking forward to the day I can actually use them with a radio or even home phone.

I just lost a nearly perfectly decoded image because I accidentally hit the delete button instead of the save button.Needs a confirm dialog. Catastrophic data loss. Also, "Auto mode" isn't clear... tapping menu button seems to do nothing. Is it active? Show a checkbox? Could be improved a good bit, but not bad for a free app.
