Try to look at this station with the waterfall graph displaying 1 Hz per pixel and a corresponding fft resolution. Since it is local to you it should have a sharp stable carrier:-)
I tried a couple of AM stations and they did not go below 40 Hz. One actually had the cut-off at 80 Hz. 73 Leif / SM5BSZ
