The line at 8820.0000 is 11.7 dB above the noise in this 1980 bin span. It is the strongest bin in +/- 0.5Hz (19800 bins). Of course, I also checked nearby integer frequencies - when using PPS GPS timing there is the possibility of weak harmonics from the timing system. I tried Cumiana with this narrower bandwidth but no improvement. -- Paul Nicholson --
