That looks as if it should be very interesting Dominique! At the moment I'm using OBS -> FreeStreamCoder -> Portsdown4 -> Lime Mini which works very well. It would be nice though to be able to free up the Portsdown for receive while TX'ing sometimes.

Good luck and 73,

Martin.

Thank you for the development Dominique F1EJP.
At the moment I'm using OBS -> FreeStreamCoder -> Portsdown4 -> LimeSDR USB which works very well.
Lime Mini settings can support LimeSDR USB to? if not please add LimeSDR USB on the selection menu.
Waiting for your new DATV_Easy V1 software for test.

Interesting. How is the PTT managed? At the moment that is done via my Portsdown terrestrially or Pluto on QO100. It would be useful if we could control with a USB relay or similar. This would account for the Lime calibration spike as well and could even sequence a pre-amp so that it is switched out before the RF. Like many, I have a power through the cable SSB electronics pre-amps for 2m, 70cm and 23cm. My IC9700 can power these, it would be useful if the DATV system could do the same.

Received the test transmission
Valid point Mike, USB relay must be added.

Hello,

Currently version 1.15 being tested on QO100 regularly
Operational from SR 25Ks to 1Ms in DVB-S2
> Still to be tested with an OM equipped with DVB-T reception of 125 khz at 1M
> Still to be tested by an OM on Pluto because I don't have one.

(the driver for the LimeSRD mini or Pluto must be installed on the pc)

This software will not be able to compete with the Portsdown or the Pluto with the software of Evariste and perhaps not with the DATV Express!
It is based on FFMPEG and GNURADIO modules, all adapted and configured under Windows.
I spent a lot of hours trying to get the best result.

It will allow you to have fun at a lower cost since only the PC with the OBS or Vmix software and the SDR module are necessary.
You need a pc with an I5 processor and if possible I7 either recent or with an NVIDIA card

I will soon put the file on VIVADATV forum for testing.

Hello,

>> I'm looking for a version of ffmpeg 4.3.1 compiled with the libfdk_aac enable library
Indeed the results obtained are clearly better with this version than the last 4.4 which causes discontinuities for a flow greater than or equal to 1M
In addition with the aac he codec we still save bandwidth
My Windows build attempts haven't worked so far.
The software is almost ready for first release.
Thanks in advance if you have this version with lifdk enable send me a message.

Hello John,

Thanks for the reply, I have tried different ffmpeg compilation solutions !
I am not a specialist in this programming and in this solution which allows to choose the version I do not know all the commands,
It's very difficult..
I keep looking.
