When I mounted the SD card on my laptop, I couldn't find any firmware file. The orders must be created when the raspberry is booted. I will ask on Kodinerds forum how to change the file.

Two days later I can say, that it is not up to the firmware file:

I "IIRC" the firmware, when creating /storage/.config/firmware and put it inside - from thjs post:
https://forum.libreelec.tv/thread/24083-exchange-outdated-dvb-t2-firmware-with-read-only-filesystem/

But the error remains. There are some channels found in 482MHz, but without name. The channel names will be included later. And all the other channels not delivered in 482MHz work correctly.

Can it be the kernel version? on my laptop I have OpenSuse Tubmbleweed with Kernel 5.11.11-1-default, on my Raspberry there is a Kernel 4.19.127.

In the libreelec forum it was suggested to do the command dmesg. The last 50 lines are repeating this:

em28xx 1-1.4.1:1.0: write to i2c device at 0xc8 failed with unknown error (status=128)

em28xx ist the kernel modul which is needed for the dvb-t2 stick.

I load the whole output file dmesg_out.txt

Is there an conflict between two firmware files?

[ 7.125042] em28xx: Registered (Em28xx Input Extension) extension
[ 7.391689] si2168 8-0064: firmware version: B 4.0.11

[ 7.447904] si2157 9-0060: firmware version: 3.0.5

Is it important that I use a USB hub with its own power supply?

I did put away the USB hub and connect the DVB-T2 adabter directly to the raspberry. Now none of the channels are correct. Before only the ZDF Mux didn't work correctly.

I attach the dmesg output for the direct connection

It's not the USB hub. I made a new SD card and connected the DVB-t2 adapter directly to th raspberry from the first boot on. The problem is the same: no ZDF mux, the other muxes work.

By the way, the downloaded firmware is older than the delivered one:

from Haupage page: 4.0.11
from libreelec: 4.0.25

​I think now the DVB-T2 stick is defect. After all it doesn't funk on my laptop, which did at the very beginning!

Hmm, I think I have exactly the same problem (also ZDF missing in Leipzig with WinTV soloHD from Hauppauge):

Manually tuning to 482000 kHz with VLC gives nothing.

Ok, manually setting this in VLC is working

This works for me (located in Leipzig).

I think they messed up something on our broadcaster Leipzig/Messegrund.

There’s something about the ZDF mux that seems to upset some tuners.

I have tried a PCTV 290e (similar to the WinTV Solo HD which I think is equivalent to PCTV 292e) and it will not lock the ZDF HD mux in Cologne. I can see the Colonius tower transmission antenna less than 2km away, but there is no signal for ZDF on channel 29. The two ARD/WDR muxes are received with no problem at all, the signal is very strong.

The same applies with an Xbox TV tuner in Linux using TVHeadend. ARD/WDR works but ZDF does not work.

I noticed the same last year using the PCTV 290e when visiting the border area between France and Germany (Strasbourg/Kehl). I could receive the two ARD/SWR multiplexes from the Baden Baden/Fremersberg transmitter, but there was no signal for ZDF. I thought at the time that it was because the signal was just not strong enough, but I now think it was also because the device has problems with decoding the configuration used by ZDF.

Hallo,

It is a bit mortifying (peinlich), but I solved my problem by moving the
antenna. Maybe the ZDF-3Sat Mux is a bit vulnerable.

And when I tried some sticks I remember there was one stick which stopped linux support at one several serial number. But I don't remember if it was a satellite or trestric stick.

kind regards
Tobias

Hallo Tobias,

That’s good that you got it working, nothing appeared for me at all even with the aerial pointing at the Colonius tower out of the window, the ARD works perfectly, including receiving the separate version of the WDR mux from Düsseldorf/Rheinturm in addition.

I would be very interested in a full MPEG-TS dump of the ZDF mux if you would be able to provide one? I’m curious to see if anything is different with the configuration which causes some tuners to fail. Thank you.

Kind regards,
Adam

Hallo Adam,

maybe I can do it, if you tell me what a MPEG-TS dump is. But remember that I'm on a raspberry pi4. So maybe it's not so easy.

Yesterday I updated libreelec on version 10. I feel as the DVB-T2 works better. Bevor that, there were some stoppings in the sound. And when I watched soccer in the afternoon, shortly pictures of the game were seen when I watched news in the evening. Now these disturbtions vanished, as I think. My TVheadend Server is now version 4.2.8-32.

For you I made a short test with some unfavor positions of the antenna. The signal is now really stable. And in a worse position ARD still works, but ZDF not.

My stick is a Haupage WinTV soloHD. And it is a Kernel version 5.

Tobias

To make a full multiplex MPEG-TS dump, all you should need to do is go into the TVHeadend web admin, and go to Configuration > DVB Inputs > Muxes

Then, copy the URL from the play button for the 482MHz ZDF mux. It'll look something like -

http://192.168.1.2:9981/play/ticket/stream/mux/0123456789abcdef0123456789abcdef?title=482MHz%20%2F%20Network%20Name

Remove the question mark and everything afterwards, and also /play/ticket, then in your Terminal in Linux or Powershell in Windows, run the following, with the example URL from above modified -

wget http://192.168.1.2:9981/stream/mux/0123456789abcdef0123456789abcdef -O zdf_dvbt2_482mhz.ts

If you're using a username/password, you would maybe need to do -

wget --user user --password pass http://192.168.1.2:9981/stream/mux/0123456789abcdef0123456789abcdef -O zdf_dvbt2_482mhz.ts

This will start dumping the full multiplex to a TS file. Let this run for something like 30 seconds, then hit Ctrl+C to stop it. You should then have a file called zdf_dvbt2_482mhz.ts that contains 30 seconds of full multiplex data. You can then upload it here on the file upload option when replying.

Thanks!
