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.
but it doesn't show any channel
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!
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)
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
Nothing with dvbviwer

My stick receives the following
746Mhz
650Mhz
690Mhz
so I doubt it is a frequency problem.
Seems to be more lack of signal.
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
