What does the contamination look/sound like?

At 10 MHz the ripple of my power supplies contaminates my output signal at a level much higher than the documented inserson loss.
So I suspect some 10 MHz makes its way through a magnetic field and perhaps a filter with only a simple annular capacitor would be  more effective.
