After "fiddling around" with some difficulties, I have it running now. Before XMAS my SDR-IQ RX arrived from the U.S. (RFSpace company). Using the VAC(Virtual Audio Cable) software I got the AF fed into WSPR and it is running very fine now. RXwise only of course.
Anyone else is using the SDR-IQ here ??
