Hi all sysops of PhantomSDR+
Today I have rebuilt from scratch the SSTV decoder.
Only two files to replace in frontend/src
- audio.js
- sstv.js
They are uploaded in the github.
I am putting them here for download. I am also including the reference picture that I worked with and I have transmitted using MMSSTV program in Windows:

DON'T FORGET to RECOMPILE Frontend only!

[Emmanuel SV1BTL]

Here are the results of the decoding in the various modes:
Martin 1, Martin 2, Scottie 1, Scottie 2:

... and Robot 36 and 72:

I have also rebuilt wspr.js from scratch (frondend/src/modules).
Github is updated, but you can also download it from here:

Don't forget to recompile frontend.

[Emmanuel SV1BTL]

All the decoders are tested and crash tested. All are working as expected.
Now I am testing a total new CW decoder. I believe that during the next week I'll release the newer CW decoder.
And after this final step.... vacations!...    

[Emmanuel SV1BTL]

HUGE upgrade of some decoders.
- WSPR decoder is a new build
- CW is a new build
- redesigned from scratch ALL SSTV decoders. The results from my tests are shown here in this topic above.
- Some corrections to QUAM. Now Opus is working by default only for c-quan (much better quality for this mode), but a sysop can bypass it and force c-quam to work in flac.

You can find all the newer files in the github. Every file that is not marked as "Initial commit" is the newer, so you can only copy these files and paste them to your server.
A recompile for both Backend and Fronend is needed and you have to restart the server so the changes to be applied.

For any question, please do not hesitate to ask.

P.S. If you have not already done it, please stop rade (./rade.sh stop), reinstall it (./install_rade.sh) and restart it (./rade.sh start). There is an update to the code from FreeDV.org

73, de SV1BTL, Emmanuel
