Troubleshooting Radio Frequency Interference (RFI) Problems

Pro Sound Web: You turn on the sound system and you hear a radio station. Now what?
Let’s lay aside the ‘magic fixes” and “voodoo methods” and set forth a methodical procedure to deal with this problem, which is called Radio Frequency Interference (RFI).
The key is to “divide and conquer.” It’s essential that the problem be localized to one part of the sound system. If more than one problem exists, these tests will help disclose that also.

Working with RF is one of my favorite things as a sound designer both when it is working and when it is not. It is one of those things that when it works you really can have an amazing sounding show...but when it doesn't then everybody in the audience will know. The part of failing RF that really intrigues me is the amount of figuring out that goes into building a successful system. This article is a very in depth way of looking at the advanced troubleshooting methods that can help an RF engineer figure out the problems that they may occur in high RF environments that they may be forced to work in.
