Evariste F5OEO has released new firmware for the Pluto: PlutoDVB2
PlutoDVB2 firmware is a dvb dedicated firmware. It uses dvbs2 modulator in fpga.
It can handle transport stream for video and also ip (dvb-gse).
It could also be used as a standard pluto and can be used by third party software like gnuradio, sdrconsole...with a PTT function on gpio.

Bonne bidouille !

I confirm no success without pilots even on the bench
Offset dish 120cm and Bulleye LNB
Not too close adjacent tx...
Takes sometimes 1 - 2 min to lock

Hello George,
I have been successful this morning receiving my 8psk sr250 signal on QO-100 with dvbs2-rx. See attached screen dump. At the moment, only by recording the TS and after looking at it with VLC.

For those who have not heard of Edouard F4EXB's SDRAngel with its modules for DATV reception and transmission, you will find below the link to a presentation made at the DATV Forum (HAMRADIO 2022) on this topic.
A DATV Transceiver with SDRAngel
Allergic to linux ? A Windows version is available which works very well now that it integrates the LDPC software decoder.

Bonjour George,
If you haven't seen it yet, there was a presentation of gr-dvbs2rx by the developer, Igor Freire at GRcon 22.
The presentation can be found on YouTube:
GNU Radio Conference - Monday Sept 26, 2022
https://www.youtube.com/watch?v=1jJWfsGeZvE
start at 58 min.
As a reminder:

Bonjour Tom,
Thank you for this nice application. Works fine here on a PI3 4Gb.
If you are looking for a feature request for the next version ... I think that a Chat window at the bottom (with an option to display it or not) will be useful making your Windows Longmind client a one-stop shopping for a QO-100 Reception.

Hello Baris,
I asked the question regarding the sat file for the following reason :
I use a Bullseye LNB that I don't want to modify. To bring back the QO-100 frequencies in the range of the SF8008 tuner, I use a converter called SUP-2400 (https://home.swissatv.ch/2013/12/lnb-avenger-et-convertisseur-sup-2400/) .
Unfortunately it reverses the frequency...
IN 250-750 MHz OUT 2150-1650 MHz LO 2400 MHz
So your plugin will be the place once working to modify to do the math for me !

Thank you for your post !
I had forgotten that the software (OpenATV 7.1) uses python 3 !
The plugin works without any problem now.
73 de Michel, HB9DUG
Bonjour Baris,
Thank you for your interesting plugin.
I have Open ATV 7.0 on a SF8008 and installed your plugin without problem but I have no success installing the websocket client.
See msg :
root@sf8008:~# opkg install python-websocket-client
Couldn't find anything to satisfy 'python-websocket-client'.
Unknown package 'python-websocket-client'.
* opkg_solver_install: Cannot install package python-websocket-client.
I tried another way by installing pip3 to be able to do after : pip3 install websocket-client... but I was unsuccessful at installing pip3.
Your help will be appreciated.

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.
All the details here :

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 :
http://home.swissatv.ch/2017/07/all-in-one/
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.
