You didn't say that your new home came
with new appliences, Your new Fridge may be
sending noise out over the power lines. Try
this site for some tips on getting noise
problems..
http://www.act-solutions.com/uncle.htm about half way down the list of articles
there is a decussion on noise. I hope this
helps you get up and running. You say that
you had a amplifer installed if you have
electrical noise you may have made the
problem worse.. Also the noise may be
outside of you mobile home, by that I mean A
neibour on the same Power Transformer may be
the cause.. I hope the series of articles
are some help..
