Try my locking fix. With above patch I can lock the
channels without problem.

Can someone confirm that such patch would fix the issue? If so, please
forward it in a way that it could be applied (patch is currently line-wrapped),
and submit with some comments/description and your SOB.

As the patch is currently broken, I'm just marking it as rejected at patchwork.

Manu,

Please take a look on this trouble report.

Thanks!
Mauro.

Sorry, the things are mixed here. My patch (resend and hopefully this
time not broken) handles only DVB-S transponders.

The FEC fix patch fixed locking on 11,681 Ghz, but not on 12,692 Ghz for
me.  But I have very weak receiption,

Hi,

Just to report that I can lock on those problematic transponders with
kernel 2.6.37 (and with an amp on the coax of 40m long), but not with
2.6.39-rc6.

I figured the patch which might cause my problem is the following

[media] stb6100: Improve tuner performance
[http://git.linuxtv.org/media_tree.git?a=commitdiff;h=f14bfe94e459cb070a489e1786f26d54e9e7b5de]


I recall that in this thread
[http://www.mail-archive.com/linux-media@vger.kernel.org/msg29712.html],
there were concerns about the above patch.

Is it possible to remove it from 2.6.39 release and do further research
or is it too late ?

Thx,

We did a lot of experiments with this card and these 2 transponders, and
here is what you need:
* The dish must be perfectly oriented
* Check carefully the X-pol (LNB rotation)
* Be careful that all the LNB are not equal: we managed to get good results
with some LNBs and never manage to have reception with other models of LNB
* It seems that the DVB-S2 demodulator (that is quite old now) in this card
is very sensitive to bad signals and maybe sensitive to cross polarization
more than other demodulators.

So make a short answer: to correct the issues with these specifics
transponders and this card, we first do a fine dish/LND orientation and then
change the LNB, usually, it's enough. Specific measurement tool is needed to
make good work.

Finally, it isn't that much a driver problem in my opinion.

Thank you Johns,

I got out of patience and reverted back to kernel 2.6.37. Added an amplifier
on the line and repositionned my dish. It works now. But very difficult to get
both Hotbird 6 and 9 sats! Maybe they transmit a weak signal ???

TT-budget S2-3200 cannot tune on HB13E DVBS2 transponder

[Issa Gorissen]

Hi,

Eutelsat made a recent migration from DVB-S to DVB-S2 (since 31/3/2011) on two
transponders on HB13E

- HOT BIRD 6 13° Est TP 159 Freq 11,681 Ghz DVB-S2 FEC 3/4 27500 Msymb/s 0.2
Pilot off Polar H

- HOT BIRD 9 13° Est TP 99 Freq 12,692 Ghz DVB-S2 FEC 3/4 27500 Msymb/s 0.2
Pilot off Polar H


Before those changes, with my TT S2 3200, I was able to watch TV on those
transponders. Now, I cannot even tune on those transponders. I have tried with
scan-s2 and w_scan and the latest drivers from git. They both find the
transponders but cannot tune onto it.

Something noteworthy is that my other card, a DuoFlex S2 can tune fine on
those transponders.

My question is; can someone try this as well with a TT S2 3200 and post the
results ?

Thank you a lot,

i read something about it lately here (german!): 
http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/p977938-stb0899-fec-3-4-tester-gesucht/#post977938

It says in stb0899_drv.c function:
static void stb0899_set_iterations(struct stb0899_state *state) 

This:
reg = STB0899_READ_S2REG(STB0899_S2DEMOD, MAX_ITER);
STB0899_SETFIELD_VAL(MAX_ITERATIONS, reg, iter_scale);
stb0899_write_s2reg(state, STB0899_S2DEMOD, STB0899_BASE_MAX_ITER, STB0899_OFF0_MAX_ITER, reg);

should be replaced with this:

reg = STB0899_READ_S2REG(STB0899_S2FEC, MAX_ITER);
STB0899_SETFIELD_VAL(MAX_ITERATIONS, reg, iter_scale);
stb0899_write_s2reg(state, STB0899_S2FEC, STB0899_BASE_MAX_ITER, STB0899_OFF0_MAX_ITER, reg);

Basically replace STB0899_S2DEMOD with STB0899_S2FEC in this 2 lines
affected.

Kind Regards 

Steffen

I can confirm that we have a lot of problem with these two transponders and
the TT-S2-3200 card.

Here are some observations:

- It seems that going from DVB-S to DVB-S2 make the antenna settings very
sensitive. We have some sites where everything is working correctly and on
some other sites where we needed to redo the antenna setup, especially the
LNB tilt.

- The STB0899 driver doesn't seem to work correctly: if the reception isn't
really good, we are missing a lot of TS packets and these packets are
altered (mainly garbage). But, the BER returned from the demodulator stay at
zero! (using FE_READ_BER ioctl). By the way, the FE_READ_UNCORRECTED_BLOCKS
ioctl isn't implemented in this driver.

Does anyone can confirm these observations?
