About this app

Following modes are supported:

Robot Modes: 36 & 72
PD Modes: 50, 90, 120, 160, 180, 240 & 290
Martin Modes: 1 & 2
Scottie Modes: 1, 2 & DX
Wraase Mode: SC2 180

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

If an calibration header gets detected, the resulting image will be saved in the "Pictures" directory and can be immediately seen in the Image gallery.

Switching away to another application will not stop the decoder and it will continue to run in background.
To stop the decoder, you can either press pause or exit via the "back" button of Android.

Here you can find my wife's free open source SSTV Encoder:

I love this app, but I've had a slight problem this last time I've installed it... For some reason the save button is greyed out, and the share button doesn't seem to do anything. Is there any reason this would be happening that I'm just missing? I had to save my last image via screenshot, which isn't ideal, so I'd rather be able to use the default save feature :) I'm on Android 10 on a Nokia 7.1 Thanks for the great app!

Thank you for feedback! You might want to try to purge the cache, as it helped a lot of Android 9 and 10 users. Otherwise please send me a screenshot of the buttons and menu entries per email.

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.
