As the environment becomes more and more crowded in the RF realm, interference has
become a major issue. Far more than simply an occasional nuisance, this phenomenon has
the potential to seriously interrupt the conducting of business, personal communications,
hobbies and even critical life support monitoring systems. As a radio control model hobbyist
myself (see my Airplanes And
Rockets Website), I have been aware for 30 years about the perils of interference
and the profoundly disastrous results that can occur is left unchecked. Preventing interference
is a big part of the cure, since it is not always possible to simply design a receiver
that can reject the interference.
