modulateurs DVB-S/S2 à utiliser avec un PC ou un Rpi

this is probably the cause of F5OEO 0303.
in 0303 the pluto is used differently for datv and NB.. in 0201 is this not a setting and should it work normally and direct.

I have tested V2.08 this week end in order to replace the previous version at F4KLO.
Congratulations for this easy to use and wonderful software.

I found a small problem:
My configuration is a pluto sdr with the latest official firmware connected to the PC by USB
I am using OBS + DATV EASY V2.08 in DATV and SDR console 3.2 in narrow band.

When I want to switch from DATV to NB:
I clicked Stop and then Exit on DATV. Then I launched sdr console on the same pluto.
I am able to receive on the pluto but i am UNABLE to transmit.
There no error message in sdr console but not power out of the pluto sdr.
A software reset of the pluto is fixing the problem ( command pluto_reboot reset via ssh on the pluto (user root pwd analog))

Problem solved by deleting the F1EJP folder in the programdata folder...

It contained old settings from the beta programs..

tks for the software.
Please could you fix the following issue.
The value for "Audio kb/s" on the first tab "DVB / MPEG-TS" will not be stored in your .ini file.
Each time after a new start comes the value "128kb/s" as a preset value.
But I want to have a lower value ( 32 K ) to have more for video.

Hello Jabi.
Port 7272 is for RTMP and 8282 is for UDP..

RTMP will stress your CPU more and thus when you have F5OEO firmware you would like to use the UDP hence 8282...

Portsdown cannot work with H265 and the UDP and you need to set the normal pluto for HW witch will give you RTMP.

Best regards

I think there is an error in the configuration of the Adalm-Pluto. Shouldn't the output port be 7272 instead of 8282? This is how I have it configured in my OBS:
rtmp://,2407.750,DVBS2 ... lib,800,32,
In udp: udp://, to send it to Portsdown 4.
With port 8282 I don't communicate with Pluto.
Please tell me something.

Bonjour à tous,

Encore merci pour ce programme fantastique.
En cherchant la signification des termes utilisés dans ce programme je suis tombé sur ce pdf bien fait et en français qui explique les différentes modulations, FEC, ...
