Sasha, 
Sounds interesting. Do you have any videos on the operation either at youtube or somewhere else?

Hello everyone,

This is my first time posting here, so please do reprehend me in case I break a few guidelines. 

For the last few months, I have been developing a new digital slow scan television mode for amateur satellites. The focus is to still be able to recover a complete image at reasonable speeds. In fact, current tests show that if 100% data recovery is desired, then up to 30% data loss can happen. If resolution is sacrificed, there can be up to 80% loss and still be able to recover the entire image, unlike sstv and other scanline systems. Also, a noise free image (100% recovery) can be received down to about 10dB SNR.

Would some of you be interested in this mode? It’s halfway thru development, and if there is enough interest I will post code on GitHub and this bulletin once it’s finished.

Thank you,

Sasha T
