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.

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:

Hi Steffen,
Unfortunately, it does not help in my case. Thx anyway.

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.

Manu,
Please take a look on this trouble report.

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,

Manu,
Please take a look on this trouble report.

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/[email protected]/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,
--
Issa

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,

Manu,

We're still missing your review on this patch[1], or it were eventually missed. Please review it.

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

- 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 ?

Hi Steffen,
Unfortunately, it does not help in my case. Thx anyway.
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.

Manu,
Please take a look on this trouble report.
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,

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.
