    • Unable to tune satellite transponders with Symbol Rate 45000 or higher

      Hi,

      I have Vu+ Solo SE V2 with single DVB-S2. It has AVL-6211 DVB-S2 tuner.
      I set-up may satellite dish to watch Videocon DTH at ST-2 (88 degree East).
      But my satellite tuner is unable to tune any channels on transponders having symbol rates 45000 or higher. And it is same with any satellite, any transponder with Symbol rate 45000.
      Tuner locks the signal on those transponders but does not tune or save any channels.
      I checked all images but same problem.

      I checked data sheet of the tuner and as per that it supports symbol rate 45000.
      I think that probably the the feature is not properly implemented in the official Vu+ DVB drivers.

      Recently (1st July, 2020) Availink, the manufacturer of AVL-6211 tuner has also released their official driver sources for this tuner (AVL-6211) here on Github.
      And as I have probed, these drivers support symbol rate of 45000.

      I was wondering, if Vu+ developers could solve this long standing issue in official Vu+ DVB drivers at their own or by using the drivers released by Availink on Github.

    • 45.000 is right on the edge of it's possibilities. Absolute no room for error. The slightest difference in tolerance will fail. You might want to test with PLL driven LNB's... Driver updates for this model are extremely unlikely it's age considering. Probably 'once in a blue moon' or 'when hell freezes over' :D

    • Hi,
      still not fix driver ?
      scan Fotelka package (same result with too 11350H), signal LOCK ok, but scan NONE
