Hi Hermann, thank you, the patch for the antenna power is working for me with the latest mercurial tree. I'm now able to receive additional weak channels. On the contrary a channel close by with a very strong signal disappeared. The stand-alone receiver with antenna power that I have can receive both channels at the same time. Am Sonntag, 30.

On many demods it is already reported, that a too strong signal might need attenuation. With the mix of different transmitters we now have, more established by means to serve federal states instead of having an over all concept, I don't wonder to get such a report now too the first time. It likely needs some RFC to think about all possible combinations of LNAs and active antenna support and how best to deal with it. Cheers, Hermann > Am Sonntag, 30.
