Thanks.  You're getting a MUCH better signal on that than I am.  I've just got to get to work and put together that adjustable FL system.  Problem is that there are so many getting ready for winter projects popping up.  I'm really thinking about pulling the Bullseye out, and putting the CoRotor back in until next spring, unless we get some good weather in the next few weeks.

So new NOAA DVB-S2 VCM transponder similar to EUmetcast DVB-S2 VCM.
Most data in 16APSK,2/3 ISI=18 - require snr > 9dB
And some critical in QPSK,1/3 (only one PID, maybe some checksum data or additional FEC).
Stream is MPE/IPv4, so can be received with TBS IP or my BDADataEx, or standard linux dvbnet subsystem (not need set any MODCODE or ISI filter). Or recommended external DVB/IP receivers like Novra S300, Ayecka SR1 (both use STV0900AAC).

Instead EUMetcast VCM contain two independed streams - basic service 8PSK,3/5 and high-volume 16APSK,2/3 for future services. Anyway can be received on one receiver as one TS (but depend from high link margin, so need big dish).

The Linux 64_bit drivers that TBS provided did not work. The 32_bit drivers are OK.

TBS support returned my email and pointed me to the FAQ that came with Linux TBS drivers.

Following the FAQ guidelines I now have TBS6983 drivers on 64 and 32 bit Linux machines.

Good deal. Did the drivers work with tune-s2

It should work with little to no changes.

UDL

UDL

Below is where tune-s2 stands at the moment:


1) make tune-s2 produced txt compile_errors_tune-s2.txt     

commented the items out.

2) make (compiled tune-s2)
installed
tune-s2 12180 V 30000 results>>txt tune-s2_results.txt     

3) dvbsnoop results>>txt dvbsnoop_feinfo.txt     

any suggestions.

Thanks

Running VLC capture tuner works ( have to set up advanced options)

Seems like you said you were using the 6983 with an os with out udl's kernel / modules. If you are using the latest tune-s2; majortom has been modifying it along the way to keep up with udl's work and some enhancements. I would assume you are using the stock frontend.h also.

Here is an old source you can try. You will have to change the includes to your system and may have to cut out the DCII here also in the tune-s2.h.

Thanks DarkSky,


I'll give it a try.

Here is another program we used way back too. Do not know if it will work with your set up or not. It would be interesting to see if it does. Try the binary first and if it does not work do a make clean and recompile and see if it does. It does not work well with udl's later work. Just might with a regular linux install.

Hi all,

StreamReaderEx-BDA 1.2.2.1248 (Beta)
http://crazycat69.narod.ru/sattelite/StreamReaderEx/test/StreamReaderExEx-BDA.rar
* Full TBS 6983 support with direct hw control STV6120/STV0910ADB
* Ultra-fast and accurate BLScan2() implementation for STV910. Hardware-accelerated edge detection + find unlockable transponders (with poor snr and negative link margin).
* New function ModInv() - detection available frame modcodes for DVB-S2 transponders. Implemented only for STV091x (now only TBS 6983)
* Rewriten CXD2820R support. Extended SingnalInfo2 with specific DVB-T2 params.

For 6983 possible force single mode and double LDPC FEC performance (DemodMode=1 in streamreader.ini). STV6120 is wide-band tuner, so possible extend IF range to 250-2150MHz (IFStart, IFStop in streamreader.ini).
With current 6983 drivers better always use Tuner A, because using B cause driver lockup after close !!!

CrazyScan 1.0.2.112 (Beta)
http://crazycat69.narod.ru/sattelite/StreamReaderEx/test/CrazyScan.rar
* Modcode selection simplified,
* Read available frame modcodes for DVB-S2 transponders in Carrier search dialog (if ModInv() supported)
* Mark unlockable transponders and ACM/VCM.
* User-defined freq ranges selection in Range tab. Predefined ranges defined in ranges.txt file.
* Move some style-specific checkboxes to Style tab.
* Save BLScan2 checkbox state in settings.

* Show in report unlockable transponder,

StreamReaderExSDK updated (API, BLScan, BLScan2)

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!
