Hi,
I am interesting in decoding CW, simply putting computer mic. near receiver
speaker when I am tuned to CW signal.

I found lots of circuit to build and soft to decode CW, RTTY etc., but non
of them can capture incoming sound from mic.

If you know any software please share the link.

Thanks in advice,
Edgar

Try hamscope. It will decode most of the popular modes. CW, RTTY, PSK,
etc...Hs dual receive windows, AFC, etc. It's free on the net. Do a
search for "hamscope".
