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?

Peter
