The 100 Hz (being 2x 50Hz, the power freq. in Italy)
suggests that it is probably related to some manner of
power supply. However, I have no theory why we're
getting 2x 50Hz (and I think I need one :-)).
Doh! When the AC wave is rectified, it results in a signal that is 2x
the freq. because the negative part gets inverted. That's why we see
100 Hz instead of 50 Hz.

On card A or X?
Why AM and not additive signals?
