Lowbandwidth DATV is possible using Digilite and Tutioune
Posted: Mon Aug 25, 2014 9:20 am
Hello,
Since this summer we are testing with Evariste F5OEO DATV at very low SR, down to 250 kS/s.
it works very well with the image that is not too ashamed to face our old VHS recordings.
H264 coding with RaspberryPi putting IQ directly in second part of Digilite
( or a PC software coding with a graph)
Tutioune3200 or Tutioune1600 that can work today down to 176 kS/s
You can see a sample of what I get here: http://www.vivadatv.org/viewtopic.php?f=72&t=332
It's a start, but it shows that narrowbandwidth DATV is now a solution in sight and we can explore this area on our bands.
We should be able to get off SR 100KS / s.
These widths as narrow bands induced should concern DX men I guess.
73 to all.
