AN93
AM Band Interference
This is a situation that one cannot see in the audio recordings. In certain areas, the symptoms include poor
connectivity rates and error rates. A good EMI common-mode filter may be necessary in some situations. An
example of an off-the-shelf unit designed to plug directly into the phone line is the Coilcraft TRF-RJ11, which can
be used for debugging or fixing problem locations.
