When doing spectrum scan of an empty spectrum (that contain no sat signal) there are bunch of false peaks with ds3103.
Is it the case with rs6060 and any idea how to handle this?

When multiple spectrum scans are started on multiiple adapters, kernel code can crash.
This mya be due to fft hardware only being present on some adapters

Hello Deepthought,

I would like to receive the data using vtm_mode in 6903x or 6909x card but the documentation is not enough. I can call this function but dont know how to get the data and what is the exact output format. If you know how to do that, could you explain or implement a basic example? If it is possible, it can be used as an sdr device or the demodulated bits can be used to implement basic receiver inside software (GNU radio or some other dvbs demodulator source codes leandvb etc.). The card has already these kind of abilities but i would like to learn and implement the receiver for educational purpose.
If modifications are needed to receive the data from the pcie card, I may do that but need your guidance.

Thanks

In piratfm/eti-tools#35 (please scroll down) a user (@mrwish7 , Adam) mentioned that his friend (whom he is helping via team viewer) uses your stid135 drivers and complained the errors he gets on Norwegian DAB Muxes on 0.8W (10720 V) which are in DVB-GSE.

I have the same card 6903-x but I'm using the TBS drivers and have no problems.

Let me summarize the discrepancies:

So his friend needs to patch a tool in order to use PID 280 instead of PID 270 and its output is corrupt.

Any chance to fix that? I've compared your fork with the one from TBS but is a nightmare to find the root cause as the fork is too much behind of its master.

Hey Deepthought

thanks for taking up this long term fight on the 6909X and multistreams in Italy ;)

I tried the drivers, compiled with no apparent issues but driver won't load properly

standard TBS drivers compile and load, but usual issues on 5.0W particularly with Rai 1 HD.

any help is greatly appreciated

Ubuntu 22.04.3 LTS, kernel 5.15.0-78-generic x86_64

pretty much vanilla with not much else going on.

When following install instructions on fresh ubuntu 21.10 system, installed modules will break amdgpu driver

The solution involves building latest driver version instead of the one from 28.9.2021. and reordering few kernel patches

mkdir ~/blindscan_kernel
cd  ~/blindscan_kernel

#check out the actual drivers. This uses the default branch which is called deepthought
git clone --depth=1  https://github.com/deeptho/linux_media.git ./media

#checkout a copy of media_build. Standard media_build should work as well
git clone https://github.com/tbsdtv/media_build.git

cd media_build

#edit "media_build/backports/backports.txt"
#remove lines 
#        [5.15.1023]
#        add v5.15_container_of.patch
#
#        [5.14.1023]
#and move line
#        add v5.14_bus_void_return.patch
#to
#        [5.12.1023]
#section

make dir DIR=../media
make distclean

when two transponders are close to each other, neumodvb assumes it is one transponder and estimates incorrect freq/width
example on 10978 V, same issue spotted at 23.5e too

proprietary code detect this properly

Hello, deeptho!
Is there any chance to support this card in opensource driver?
Now, card is recognized by the oficial driver, but i unable to tune to any channel. Tested with mumudvb and tvheadend! Ubuntu 18.04, kernel 5.4.
