Your screen will staty gey until you will receive enough continued packets to decode a picture.
But If I see you TiouneDataGraphic on your TiouneMonitor, RF level grow high enough, but MER stay low.
You need almost 4 or 5 dB of MER to decode packets and if I look at the graph your MER stay below 2 dB ( max 1.36 dB)

MER is Good but this is not a DVB signal, you don't have any lock on frequency and SR, no FEC detected ... I suppose this just a tune with just a carrier...

MER is digital noise (S/N) . You can have difficulties to decode HamTV, even with good RF signal, if you have too much noise.
That can be Phase noise. If you don't use a down converter with very low phase noise, you could have good RF level but bad MER due to phase noise.

Sorry, I try to help you, to understand why you have difficulties. I don't know exactly how is your installation.
Could you describe it to me?
