I have an Eton E5 which I connect to my laptop via the Line Out on the
Eton to the Line In on the laptop.

This works great for recording shortwave broadcasts, but if the laptop
is plugged in, it generates some interference on the radio (only when
they are connected via lineout / in). If I unplug the laptop, there is
no interference.

Does anyone know if there is anything I can do to get rid of the
inteference? I want to set up my machine to record programs overnight,
so I can't leave the laptop unplugged.
