As others have noted, EVERY conductor is an antenna, and most computers
and rigs are built with manufacturing/design defects that couple RF from
attached cables inside the the box to cause problems.
Here is a tutorial on the topic, and an applications note for finding
and killing RF noise. The same ferrite techniques for killing noise
apply to killing RFI on cables in our stations.
Many thanks for this excellent information, Jim !
I have noticed that the display of laptops and standalone ones, the
power supply of PC's and laptops are often the source of very bad noise.
Where can we find good recommendations about which product to use or to
avoid ? There is many information available about acoustic noise of
power supplies, but nearly none about radiation and electrical noise.
Best wishes,
