Hallo, a lot of not successfull work with SDR in general and especially with I/Q-concepts depend from the performance of a soundcard.
A simple test-circuit and some screens of the soundcard-result using
SDRadio can be seen on:

I have a lot of not and more successfull tries within different cards.
Now I seem to be able to chosse the best one for my work.
