That's how the "504kHz-carrier" looks like here on Perseus.
Actually two carriers,one a bit lees than 1Hz below and another,
a bit more than 3Hz below.

The sidebands spread 900 hz spaced each side of the carrier at 100 hz
intervals.The dirt has now gone, fault rectified.

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 ..
