I use the FA-recommended setup. Upgrading my antenna significantly increased (+75%) the # of logged points. I see a lot of antenna questions here, and I can say that the difference was huge.
However, I only see a modest range increase. This leads me to believe that I want more than the SDR stick’s 8-bit dynamic range. Would upgrading the receiver help?
(1) Has anyone used a higher resolution SDR with dump1090? And is there a list of compatible receivers somewhere? I want to be careful because all the ones I’ve found are a big step up in price and I am new to SDR. The FunCubeDongle (http://www.funcubedongle.com/) has 16-bit resolution and claims to work without drivers.
(2) For those who have used amplifiers, have you done a before-after comparison?
