SpecLab only can show what it's getting from the front-end. > -Is it possible to disable any nerving 'sound boosters', AGC, etc..? Never observed such running Linux/ALSA. > -Do you use them for amateur radio _without_ a decoupling AF transformer, Why that? I'm quite happy running decoupling AF-transformers. Do you really need constant phase response over many octaves? 73 es gl de df3lp, Peter
