Dear GNU Radio Community,
I have demodulated two AM&FM 30 Hz Signals in gnu radio companion, receiving a VOR signal using usrp n210 from a signal generator SMA 100A via SMA to SMA cable, but there is error in the oscilloscope (QT GUI time sink) in the phase difference btw two signals of 30 hz, when I set bearing angle of 20 deg from a signal generator, the signals at time sink in GRC is giving 0 deg phase diff, and at 90 deg bearing angle, phase diff is 40 in grc, so what are the issues? Is it bcz of any phase offset in usrp n210 or any other problem.
Kind regards
