[1.] One line summary of the problem:
Kernel 3.8.x and later - DVB-T-USB-Device with module dvb-usb-rtl28xxu -
doesn't get signal on some frequencies
[2.] Full description of the problem/report:
I am using a Terratec CinergyTStickRC (rev3), it's a usb-dvbt-device
with device-id: 0ccd:00d3.
Usually I am looking TV with vlc and use a channels.conf with 12
channels, of which each four use the same frequency: 538 MHz, 594 MHz
and 618 MHz. I am able to switch to and between the 4 channels of the
first frequency-set on 538 Mhz, but the other frequencies don't work.
I tried the kernel-images 3.9 and 3.10 from the ubuntu mainline
kernelpage, but found the same misbehaviour as described above.
Maybe the signal of this channels is too weak. However, I can't
remember, ever to have got a signal.
Also, the device and all channels worked perfectly with the
older 3.5-kernel which I've used before Ubuntu 13.04 switched to version
3.8, and a driver I found on [
https://github.com/valtri/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0
]. I used the same hardware and software setup, the only difference was
the kernel and the driver.
So, as I hope, that it is a driver problem (and my antenna strong
enough), maybe the reason for my problem can be found in the difference
between the two driver sources.
I gathered some information from userspace as I didn't know
how to debug this problem otherwise:
Under [8.] I attached
- the channels.conf
- the dmesg output
- the usb device information,
- the output of `tzap` switching to the 3 different frequencies and
- the output of `dvbsnoop -s feinfo` while watching the channel and
after plugging in the device,
all sorted by kernelversion.
Please give me some advice, if I can provide other informations which
help.
Thanks in advance,
Jan Sieber-Taegert.

Hello
It is e4000 driver problem. Someone should take the look what there is
wrong. Someone sent non-working stick for me, but I wasn't able to
reproduce issue. I used modulator to generate signal with just same
parameters he said non-working, but it worked for me. It looks like
e4000 driver does not perform as well as it should.
Maybe I should take Windows XP and Linux, use modulator to find out
signal condition where Windows works but Linux not, took sniffs and
compare registers... But I am busy and help is more than welcome.
regards
Antti

Hello,
when the culprit is the e4000 driver but the old driver from
https://github.com/valtri/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0
worked for me, then must be somewhere there in the driver sources a
solution for the signal issues.
Does it make sense to look for a particular string in the sources? I
don't have any clue of coding but perhaps I can be helpful in this way.
There are
- tuner_e4000.c
- nim_rtl2832_e4000.c
Thanks,
Jan.

Feel free to look. Those are different drivers and you cannot compare
easily. For my experience you will need huge amount of time and much
luck with that approach.
As I said, the easiest solution is just to took sniffs and copy&paste
generated code until it starts working.

Could you test attached patch?
It enhances reception a little bit, you should be able to receive more
weak signals.
I was able to made test setup against modulator. Modulator + attenuator
+ attenuator + TV-stick, where I got picture using Windows driver at
signal level -29dBm whilst on Linux -26.5dBm was needed. With that patch
Linux driver started performing same as Windows.

Hello,
unfortunately your patch doesn't bring any change: I rebuild the kernel
with it but the driver still gives no signal on the two higher frequencies.
For safety I tried the channel.conf with windows and vlc and everything
worked as it should.
Thanks,
jan

Hello Antti,
Unfortunately the patch doesn't work for me either. Would it help you if
I send you an usb sniff with wireshark of an program search run with
kaffeine (27 MB)?

Hello
I don't want to read any random logs. It is just like looking for a
needle in a haystack. Waste of time.
I wrote a blog post and published my rtl2832u
reverse-engineering/hacking scripts. Try to follow those:
