Hi Sebastian,

What do you mean by I/Q block? All blocks that work on complex samples
are practically I/Q blocks, no?

I guess you mean I/Q input block. Since you have connected the radio
to your sound card you want to use the "Audio source" block with two
channels, which will correspond to I and Q.
