Hi Marcus, I believe this explanation by the author clarifies the issue you raise: http://www.reddit.com/r/RTLSDR/comments/uje3q/sample_python_code_and_results_for_iq_correction/c4w47bt Alex _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
