@ f4fdw Laurent bonjour aujourd'hui j'ai essayé le program DVBT en RX aucun résultat de ma part dvbt_rx_v2.py je dois mieux comprendre comment je dois me comporter sur la partie TX si elle est compatible with système DVB_T_Rpy_ avec le système DVB_T_Rpy_ seulement 10mW je vois pour bien vous comprendre ce que je recommended in the système TX à utiliser

hi Tony
Pour ma version du dvbt , il lui faut par défaut du 2/3 fec et du 1/32 en guard et bw 66,250,333,500khz , 125 et 1000mhz par le menu ,
si tu veut faire autre chose in faut lancer la soft avec d'autres options , ex. dvbt_rx_v42.py -h pour le help et l'on peut voir les options pour changer , -c pour la constellation , -r pour fec etc.... , en sachant que le réglage du RIT est pointu pour avoir la constellation ,
.
bonne reception

hi laurent,
tonight we have test the version V42.py on windows 10 with gnuradio 3.8.2.0 64 bit
we could get a constellation but no image on vlc . the python file was edited to the port off 8888 and 127.0.0.1 ip:
no image arrived. the version v2.grc was opened in windows without problems see the attached image received with the experimental grc
nice job , 73 de ik1hgi tony
Buongiorno Tony
This is a problem on window which blocks the UDP, I added the TCP (tcp://@127.0.0.10:10000) with vlc on version 4.2 on my site, you can reload it and it should work.
good hack

Hello SWL - markro92,
do you plan to add DVB-T support to your software soon?
At the moment there seems to be no software able to receive narrow band DVB-T under windows, dvb-s_gui seems like a very good candidate.

Hello markro92
I think so too, we need a DVB-T soft for narrow bandwidth. It can also be a small program of its own.
It doesn't need to have many functions.
I've been looking for it for a long time but there is no suitable software.
Grüße Klaus DH1KP
Any update soon I wonder ? Been quite a while now
I think its to late, Markro92 is in other project,s employed

OK fair enough
Hello markro92, I see that we are stopped of your project DVBS-GUI hope not to have abandoned of your fabulous project? we are always waiting happy to be able to try your realization of the program GUI NEW, give us some suggestion we are in so many OM of the waiting of the program, some suggestion yours written for all us?

I tried dvb-s_gui_amsat and had good results with the wide band tv channel plus a couple of narrow band transmissions but most of the transmissions just will not decode.
as a general rule are the transmissions all DVB=S2 or are some S1?
and the various other settings do they need to be changed from the default? obviously the sym rate has to match the transmission but what about fft, bb gain, spectrum, rf filter, rrc taps etc?
all the signals I tried look strong and I set the sym rate correctly output to vlc is tcp and carrier recovery is enabled just as with the working transmissions but no video on most.

I suggest that you read this whole thread and then you will have all your questions answered.

I read a lot of this thread but 790 posts are a lot to read through, are there any general rules and guidelines?
Display MoreHi, i just want to let you know that a new release is around the corner.
First, i want to apoligise for promising a release date i couldn't deliver.
I simply lost the motivation working on this project, because
i wanted to implement all the features in one go, getting stuck mid-way.
So i'll do smaller releases. The first one will cover the missing 16APSK / 32APSK support.
I do tests with broadcast transponders at the moment, but it still needs some fine-tuning.
Marcel
great SWL - markro92 hope it's ok i will do the first tests when it's available thanks for the image 73 Tony ik1hgi
Markron92 also tested this morning the Beacon fast and tuning today we wait for someone to transmit 16Apsk I 32Apsk I asked Frank test a test thanks for the great work announcement of the new version DVB-S V2.1.0

hello Marcel
I tried your new software but with the RTLSDR key no way to lock a program and with the Pluto it works from SR1500 to SR250, below I no longer lock, there is a lack of sensitivity compared to the old version , good continuation
73 F4FDW Laurent
After a lot of tests, I managed to demodulate with RTLSDR even in sr66 but in qpsk, no tests yet in apsk for lack of TX on Oscar 100, it would be good to find the sensitivity of the old version, great software
