Once I do I'll let you know works alongside the other T14 BR stick. With regards to the force_lna_activation parameter, my understanding from looking at the code is that this parameter only get utilised when using a Hauppauge Nova-T 500 Dual DVB-T. With all other tuners I believe it is being ignored, although someone might want to double check this. Are you sure you are observing a noticeable difference when passing the parameter to the module? I tried doing the same thing, and when I didn't notice a difference I had a look around the code.
