Software DVB-S demodulator

Its works for me

Gibt keine problemen bei mir

OK I test tnx

ON7KEC tnx for info

all ok : thumbup:: thumbup:: thumbup:

I just can't get this last version to work in DVB-S. It locks to the signal, nice clean constellation, but it refuses sync. Does anyone know if this actually works in DVB-S? 4Ms?

Hey,

Its works here no problems..

Working conditions??

what do you mean with 4mbs?? Symbolrate ore Bandwidth?

Greetings

4Msymbols. It locks fine. I just doesn't decode the data.

Hello,

do you decode the WB beacon?? SymbolRate=1.5M

witch stations do you decode with 4m symboleRate?

4Msymbols. It locks fine. I just doesn't decode the data.

This is not on the satellite. It's DVB-S local repeater. Line of sight, 20 dB C/N. No multipath. Rarely it gets a frame but soon loses sync. I have given up as I don't think the package is able to do this at the moment. Something is probably broken so I will wait for the next version.

I was looking at a terrestrial repeater, not the satellite. No satellite dish here. I can look at that next time I have it set up. Doesn't seem to try to decode. I also noticed it locking up with a great QPSK constellation on a CW carrier. That's can't be right.

Here is a rare example of it properly locked

Hi SWL - markro92 , I'm now playing around with a synthetic DVB-S2 sample (so practically perfect), QPSK 2/3 fp32, but no pilots.

The new version shows no fft (although I can confirm it with leandvb) and I cannot get it to find anything. Do you support DVB-S2 without pilots?

Fantastic update , now DVB-S2 Demod GUI finally receives and decodes correctly the 5 Ghz band with Adalm Pluto! Congratulations and thank you very much ... https://www.facebook.com/14021…videos/10218645853843156/

SWL-thorens : i fixed some issues with the FFT plot,could be resolved in the next version. Could i have your test file? maybe truncate it to a few seconds of data.

I support Pilots on/off and also dummy frames.

Edit: Okay, found a major bug looking at the code, i'm dividing the floats by 32768, instead of multiplying with 32768. should be easy to fix. now you know the workaround I actually didn't test the F32 stuff, but you could also use signed 16bit.

Thanks for the swift reply, converting to int16 definitely helped, perfect constellation in place

Last night I made a test to see if the Miniatiuoner receives the 5.7ghz but nothing to do only 2.7ghz sin!!! After so many tests finally I find myself a moment to try DVBS-GUI V2.0.21 I made tests and I was happy with the program made Macron92, I can not do remotely I have only one Pluto and a PC works, in the transmitting part OBS + PLUTO and receiving DVBS-gui the signal 5720,000 mhz the image receives with VLC seems that everything is perfectly ok thanks to the work done tested only test 6000,000 mhz only personal purpose also works well

In your mini touner you connect to parabol directly? This case the frequency is 739,... Mhz, ok?

Hello yes on the Minitiounes and connected on the dish In this case the frequency is 739, Mhz all digital modes and on the DATV band but I do not use its 12/18 volt power supply of the Minitiounes, I have a box I use an external power supply 16+ volt power supply of laptop PC, my voltage I use for the two band cw,ssb,and other modes, DATV I work this way....
