6903X Problem Tuning

[mrwish]

I have now tried the deeptho blindscan version of the drivers - https://github.com/deeptho/linux_media

This seems to fix the problem of not being able to lock DVB-S2 after locking DVB-S2 MIS/PLS -

Code: Select All Code

tsp -v -I dvb -a 0 --delivery-system DVB-S2 --frequency 11013000000 --symbol-rate 35300000 --polarity V --modulation 8-PSK --isi 3 --pls-code 16416 -O drop

However there are still problems with the MIS/PLS signal itself, I'm still getting missing/corrupt TS packets for the Rai multiplexes on 5°W (e.g. 11013 V 35300 ROOT+16416 MIS 3 as above). The SNR level of 9.7dB should be more than enough for perfect lock of DVB-S2 8PSK 2/3 which only requires 6.6dB. These also worked perfectly on the TBS6905.

I'm still wondering if the hardware itself in my device might be faulty?

Do you seem missing the pls code parameters?
--multistream-id-pls-mode ROOT--multistream-id-pls-code 16416 --multistream-id-is-id 3

@mrwish
I have the same problem. Did you manage to solve it?

[crazycat]

look like fixed

It works but there is still some error.

Locks and scans only one frequency (stream) at a time. There is an error at other frequencies tuning failed.

maybe absent isi 3 on 11013 V ?

just test it on 9E multistreams:

No, stream 3 is available. It always tunes only the first stream. With the TBS 5927 card, it is not a problem to tune in all streams.

I found out that when combining DVB-S2 and DVB-S2 MIS/PLS the signal locks and station scanning also works (DVB-S2, DVB-S2 MIS/PLS, DVB-S2, DVB-S2 MIS/PLS, etc.).

With this combination, it is interesting that the signal is without errors. There are errors in the signal (BER) when scanning the DVB-S2 MIS/PLS separately.

I make some optimization in stid135 code, please try it

Still same issue.
