Thanks to Evariste and the various contributors to the 2808 version which works like a charm. A wish , Keep It Simple and Stupid (KISS) so we don't end up with a GUI crowded with too many options... Patch.zip is there for these additional options.
Just an example, we have the BATC Spectrum but now we have a button to disable it...

Bonjour Roberto,
With the 2408 version, I especially appreciate two functions :
- the spectrum display with the "Click" to set the channel frequency
- the Transverter LO option
As the spectrum display was developed before the Transverter LO, unfortunately the "Click" function doesn't take into account the Transverter LO option if used.
A wish for the next version.

Roberto,
Patch works like a charm !
Merci and 73 de michel, hb9dug
OUAH !
Merci Roberto, I will test it today.
The up converter I am using is the BU-500 from Hides.

Hello Roberto,
I don't see the LO transverter parameter (2208) ... maybe the last mods by Christian F5UII have broken pluto.php...
A nice addition will be a free field to enter the LO to cover the non-standard transverter like mine...

I found a very interesting article some time ago on how to configure ffmpeg with NVENC . Look at the answer : Here is a rough guide to tuning the encoder.

Hello George,
Good idea to start to play with GNURadio, a fantastic tools for our hobby.
I had a look at your grc flow-graph and I have seen that you are using a TS file from Ron (adv16apsk910.ts) which as been recorded for a transmission for a 16apsk modulation, SR 5000 and a FEC 9/10. With your configuration QPSK, SR 33 and FEC 9/10 you have a TS bit rate available of around 59 Kb/s and you are feeding the DVB-S2 modulator with around 17.83 Mb/s... No chance it will work.
I have made a presentation in 2017 during the DATV Forum at HAMRADIO 2017 of a DATV SDR Experimental TX/RX solution called All-in-one.
All the configuration files are available on the swissATV web site here :

I hope this will help you and I am looking forward seeing you on QO-100 with a TX based on GNURadio !

Hello Adrian,
You can have a look at a prototype I have done. All the info is on the home.swissatv.ch website here:

For the lucky owners of an Ettus gear, Matt KB1VC has developed a multi-mode VHF/UHF/Microwave radio transceiver that runs on Linux : SoDaRadio
All the details on https://kb1vc.github.io/SoDaRadio/
At my request, Matt has been kind enough to make a version for QO-100.
You will find it on https://github.com/kb1vc/SoDaRadio/tree/SatMode. No kit for this version, you will have to compile it. 
Bonne bidouille we say in French.

Display MoreMichel,
A zip file containing the GRC file is attached. Please note that you need to install limesdr.
Its quite untidy at present but I am working on a hierarchical version.
Let me know if you have any questions.

Mike,
Merci for the GRC file, i will test it when I return from CJ 2019, the annual gethering of the microwave fan.

I would be interested to test you GNU Radio code. Can you share it ?
The https://github.com/Blockstream/satellite contains the development sources of a GNU Radio-based receiver for the Blockstream Satellite network. Very interesting.
