The basis of this tutorial is a combination of my engineering education, 60 years in ham radio, my work as vice-chair of . home audio system, Ethernet signals on CAT5/6 cable, and the RF signal carried by the feedline connecting our . this function. There is an excellent discussion of this in w2du.com/Chapter05.pdf
Audio Systems Group, Inc. audiosystemsgroup.com 55 years in ham radio, my work as vice-chair of the AES Standards Committee working group on EMC, and extensive re- search on RFI in the pro audio world where I've made my living. In PDF form you can download his ten-page “white paper” at this link:.
your receiver audio output.3. Finding the RFI Source. Once you have an idea of what might be causing the RFI problem, you still need to find the source. Figure 1 shows a block diagram of the HF RDF system that I use. Grow light RFI is often prevalent in the. 40 meter band, but a Yagi antenna is obviously not practical.
RFI and Ferrites. Jim Brown K9YC. Audio Systems Group, Inc. Santa Cruz jim@audiosystemsgroup.com. Primary Interference Mechanisms. • Common-mode Nearly all ham gear has pin 1 problems. – Mic inputs. – Keying inputs. – Control inputs and outputs. • Nearly all computers have pin 1 problems. – Sound cards.
RFI. 1. Proper grounding of all electronic equipment is of paramount importance. In a modern station, many items of equipment are connected: transceiver, power amplifier, PC, control boxes, switch boxes, If you use microHAM "keyers" a good test is to remove the DB15/DB37 connector and USB cable from the keyer.

Member Bob Cordell covers this in his big book 'Designing Audio Power Amplifiers'. Jim Brown covers this in his paper: A Ham's Guide to RFI, Ferrites, Baluns, and Audio Interfacing Revision 5a 5 Jun 2010 by Jim Brown K9YC Audio Systems Group, Inc. www.audiosystemsgroup.com/RFI-Ham.pdf
Please provide a basic, non-technical, explanation of how RFI gets into a microphone (wired or wireless) or into the sound system, and why I hear it?
Ferrites and High Power. • If both conductors of high power circuits are wound through core, the fields cancel, so only the common mode current contributes to saturation. • Thus, ferrite common mode are effective on loudspeaker and power wiring. • Common mode chokes have no effect on audio, video, or control system
