I have two TBS devices in a Intel equipment.

TBS6991SE and a TBS6905
Drivers - 151105
Test frequency Hispasat 10730 H 27500

- 6991SE is able to lock when no modulation is used in command line (dvblast legacy)
- 6905 is not. I don't see any lock. I only see sync being acquired and lost, using dvblast.

Is this a limitation in the 6905? Can't 6905 automaticly switch to 8PSK in case of DVB-S2?

Didn't have this problem in the TBS6985.

Hi Nrm

As TBS6905 using ST chip not the one as TBS6991SE and TBS6985.
For ST chip it need to input the modulation parameter for DVB-S2 signal.It is normal.Please do not worry about this.

Thanks

Kind regards
