Realtek RTL2832 DVB-T

[email protected] · June 2, 2017 at 12:35 PM

I think there is not a correct driver for this device.

I just investigate a lot for this subject and I finally arrive here because the comment of an user in this post:

DVB-T USB RTL2838

The problem Is that the device is detected by LibreELEC and TVheadend but it doesn't work propertly with the muxes.

Thanks a lot and regards. If you need any more info please ask me.

these Chipsets are known to be problematic, some work some not

I can't tell if its an driver problem or you use it "wrong".

If it is a driver problem I can't do anything, if you use it wrong I could guide you.

Will be helpfull if I send one to you?

I really think that is a driver problem, as I said, tvheadend shows the device, but it doesn't show any channel.

I wrote this guide in my web, this is the way I use it.

Thanks for everything!

but you know that it is ONLY DVB-T1 device and not T2 - afaik there is not much in DVB-T1 to see anymore ?

I just plugged in my rtl2832 to a running LibreElec and was able to set it up in Tvheadend without problems.

Did you see any channel?

Cvh, in my case I saw the adapter but it fails in the scan moment.

Thanks!

[email protected] · June 13, 2017 at 11:08 AM

Ok I tried in W10 (no Kodi) and it does the same. Image Attatched.

CvH, I'm reading that in Spain we still with Dvb-T1 until 2020, so, is a general issue with the driver?

Regards.

**CvH** · June 13, 2017 at 12:56 PM Official Post

hmm maybe antenna (reception is too worse)? maybe the stick is faulty ?

unlikely that all drivers fail (not ruled out of course)

Yes I can view all channels available on the two muxes in my location..

Did you create the correct network for your location and apply it to the device in the tuner settings in tvheadend?

I've an online store and I ordered 10 of this devices, all of them do the same. They can be broken but is very strange.

Yes, I did all the steps so many times and with differents tests. Even my customers tried to configurate them with same results.

like said unlikely, i would bet at not that good reception -> try a better position or a better antenna

I tried with a MCX adaptor to the main antenna of the building. (Yes, I tried a lot of things, bodering you is my last resource)

Maybe this is helpful, this is what happen when I force my Network to Scan.

to be honest I would try it at Windows with Dvbviewer if it works there, if not we can rule out that it is a driver problem at linux

the stick could have problems with these frequencies (from hw side) - not to sure if this is fixable at all

My stick receives the following

746Mhz

650Mhz

690Mhz

so I doubt it is a frequency problem.

Seems to be more lack of signal.

**CvH** · June 16, 2017 at 4:48 PM Official Post

could you check with an different stick if it is working at all ?

DVB-T offers a lot room of errors and mistakes

it could be the stick, it could be that you have no reception at all - hard to judge from logs
