Yup, Ive locked that tp before as well, looked at the signal and never found much of anything of use on there, seems like a standard internet mux, I see http requests, email etc. Never seen any TV services.

Did the pull compiled/installed and tuned in ION HD and seems to play fine with no errors between the heavy down pours of rain. I will be able to test more after rain.

Edit: Had a chance to test the latest v4l-git tree modules against the v4l-majortom-modified-hg tree modules and so far I can not see any difference now. They seem to start throwing BER errors at the same time and picture viewing is good.

Thanks UDL and majortom for your work,

I was messing around a decided to run stv090x-scan program while booted up with the latest v4l-git modules installed with kernel 3.11 and the program works good with a nice picture on ION HD. The only info on the tp that is mis-reported is that the Signal S Q is down by half.

for kicks I tried the same thing, v4l-updatelee-git running stv090x-scan
and it still reported the wrong frequency, as expected. Are ya positive ya were running the -'git' tree?

Wierd thing is that cut 2.0 were effected and cut 3.0 were not even though they executed the same code.

What do they mean when they say Cut 2.0, Cut 3.0, etc??

That is strange. I just double checked and I am running the latest v4l-git from the pull today. I went to my file explorer to my other os where I was running stv090x-scan and double clicked on the bin and had to redo the config setting so they could write to my home directory. The stv090x-scan bin was built a few weeks back with s2-liplianin-v37-udl tree when I installed debian.

Here is a pic of stv090x.ko properties box showing installed today and another pic of METV scanned in and playing. The Signal S is off about 10 units and the Signal Q is off by about 30 units. Other than that it does ok. Also a pic of updateDVB same channel.

"Demod" being the STB6100 or the STV0900?

Kinda confusing because in linux they call the "frontend" driver the stv0900, and the "tuner" the STB6100. Which when ya look at the cheesy block diagrams on the ST site, the RF IN is to the STB6100 and the the STB6100 sends the demodulated I/Q samples to the STV0900. To me, the Frontend of any radio receiver is that which is closest to the antenna.
Must be missing something simple here.

Check which modules are actually loaded with lsmod.. see what is in there stv0900 or stv090x. Should be one or the other.

Would it make a difference with me having prof 7301 an you having prof 7500?

yeah, that's probably the difference.
I thought I remembered your stv090x running updateDVB reporting incorrect frequency on read back too though??

Here, even tune-s2 reports the wrong freq, because the driver is reporting it wrong to user land.

~ $ tune-s2 11840 H 3000

Can't speak for the arbitrary driver naming, but the "Cut" in this case refers to demod. IQ samples are not demodulated prior to entering the demod.

I changed how the stv090x reports quality. It used to report % which is stupid. So I changed it to db, I wanted to pick a formula that roughly meant that old apps would show something half way usefull and new apps would show db. so I chose db = returned value / 256 old apps did % = returned value / 65535 it doesnt match up 100% but it returns something semi usefull on older apps and is correct on newer apps. I have to send the v4l mailing list an email asking them why they chose % instead of db and if we can get it changed back and if so how todo so.

have you recompiled tune-s2 pointing to the new kernel tree? looks like you havent.

Quick Navigation:

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
