Ratings and reviews

I used this to decode sstv images from a local ham net. Works fine. Any issues I had were due to orientation of the android phone in relation to the speaker, or transmission errors from the station I'm listening to. The app itself, as far as I can tell, seems to be working extremely well.👍👍

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!

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.
