Hi Stefan, You asked: -Are there any spikes on certain frequencies, e.g. 8 kHz? http://abelian.org/scard/ -What is the noise floor shown in SpecLab (in 1 Hz BW) ? 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 |
