It depends depends devices, currently only nanoStick T2 only looks that param, other just ignore. If there is two nanoStics then both have same LNA settings. That's just like same behaviour as for example remote controller polling. Or for example DiBcom driver LNA, since it does have similar module param already. Will you you commit it if I rename it similarly as DiBcom? > 3) the better would be to detect if LNA is needed, or to add a DVBS2API > call to enable/disable LNA. True, but it needs some research. There is many hardware which gets signal input from demod or tuner and makes some fine tune according to that. We need to define some new callbacks for demod and tuner in order to do this kind of actions. Or just add new LNA param to API use it manually. regards, Antti

I did some testing in my environment, and I was unable to tune anything on either DVB-T or DVB-C without the LNA enabled. I'm of course aware that this depends on your signal, but have you actually seen a real life signal where tuning fails with the LNA enabled and works without it? I do believe that my DVB-C signal at least is pretty strong.

Here in the UK the mux strengths and parameters are all over the place. I have had situations in the past (with dib0700 I think) where I've had to twiddle the force_lna setting one way or the other depending on how they've decided to reconfigure my local transmitter. So I'd be cautious about flat-out enabling it the whole time.

I would then just add a LNA option via DVBS2API to allow enabling/disabling it. (LNA enabled seems to be the better default). Modprobe parameters for things like that sucks.
