Carrier is 30 db over the noise floor at Liverpool , no hum lines
showing,
only modulation spread , nothing showing at Birmingham either
http://www.wireless.org.uk/grab/
If it was 100 Hz hum , then the side bands would be , 503.900 and
504.100 .. that was the reason for picking 502.4 as the wspr frequency
to make use of the 100 Hz window under 504 ..
