Dissimilar metals can rectify, if not very conductive anymore, then you
get
some harmonics, or generate IM.

Re rusty connections!
Apparently there was a situation in UK many years ago where an electric
heater with the old fashioned heating 'coils' was picking up radio waves.
Also a poor connection became a rectifying junction (something like an old
time crystal detector) and the metal of the heater became a sound box.
When some interference problems were being investigated the elderly lady
who
owned the heater was asked why she hadn't mentioned or complained about
it.
Her reply was that she enjoyed hearing the voices and the music that came
from the heater!
Cheers. Terry.


Love it! AND... it's plausable, too.
