Power Line Noise - 50 Mhz

(click to see larger)

Now I know what I'm looking for I see this 'signature' and stronger versions of it all over the place on the radio.

Note the 60 hz, and stronger 120 hz, and subsequent 60 hz increments.  These are a well known 'signature' of the North American (US anyway) 60 Hz AC Power Line Noise.

Below is a much stronger version of this down around 44.4 Mhz.
