*** Don't anticipate too much -- the term RFI is equally confusing.
Some hold that RFI refers only to interference caused by a transmitter
getting into a receiver where it isn't wanted. Others hold that RFI
refers to interference caused by 'other' electronic devices which
radiate but aren't supposed to.
This is not much different from the interpretation of QRM.
