Default Interference on Radio when recording to plugged in 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.

You have a ground loop. Get an isolation transformer, say
Radio Shack 270-054A about $15, and insert it in the connecting audio
cable.
