Magnetic Loop antenna  ^pop - Why is an Magnetic Loop antenna so special, this antenna is picking only the magnetic part of the elektro magnetic radio wave. The big advantage of this antenna is that the electric interference from the big city have no influence on the received signal

Interference Cancelling System - The use of interference signal cancellation has been around for some time. The idea is to use an auxiliary antenna almost any random length of wire in addition to the main receiving antenna

LinkPlus - LinkPlus products enhance the voice quality of HF SSB amateur. Eliminates virtually all channel noise and interference and greatly strengthens SSB radio signals

K-Com - comprehensive line of products for rejection of Radio Frequency Interference (RFI) to telephone equipment.

bhi Ltd - Design & manufacture of Noise Eliminating speakers and modules for effective removal of unwanted noise & interference from SSB, HF, VHF, FM & UHF using new DSP technology

DCI Digital Communications - Band pass filters, for radio frequency interference problems.

About digital modes - The digital modes provide a wonderful opportunity for those of us who would like to work on the HF bands but find CW too difficult and SSB phone prohibitive because of interference problems. The digital modes are easy to set up and get operating, require low power and a narrow band.

Albuquerque Transmitter Hunting - An active group of Amateur Radio operators who locate hidden transmitters for fun and in times of need, such as determining the source of interference to local repeater systems or individuals who use the Amateur Radio bands illegally.

Radiodan - W7RF - BIRD RF power measuring, new and used, HENRY RF power amplifiers (used HF amps), TOHTSU coaxial relays, SAMLEX power supplies, RFI chokes reduce interference, Parts parts, tubes, Used amplifiers, radios, antennas and accessories, Los Angeles, CA.

Eliminate That QRM - reduce or completely eliminate interference from almost any local source whilst leaving the wanted signal relatively unaffected, even though it may be on the same frequency

Ferrite on Reducing RFI - Using ferrite to reduce radio frequency interference with your PC monitor or antennas with your receivers or transceivers.

Interference Handbook - Interference to home electronic equipment is a frustrating problem; but, fortunately, there are several ways to deal with it. This handbook provides a step-by-step process for eliminating the interference

RFI Information Page - This page gives information about Radio Frequency Interference, the unwanted reception of radio signals. You'll find out how to determine what is at fault (the transmitter or the receiver) and what you can do in either case.

EMI from Lamps - Radio Frequency Interference To/From touch lamps and dimmers

Using ferrites for interference suppression - This tutorial is meant to shed some light on the use of ferrites, and also presents some comparative frequency domain measurements both to illustrate some of the points, and to give designers an idea of what they might expect in using and specifying a ferrite component

Ham Radio Online - Computer Networking RFI - This page is to provide links to resources and information regarding technologies to reduce computer interference

Cellular Phone Interference - Cellular Phone Interference and 800 MHz Public Safety Radio Systems: An Unforeseen and Dangerous Problem

New Developments with PLC in Japan - The Japan Amateur Radio League (JARL) is cautiously watching new developments concerning the commercialization of Power Line Communications (PLC), while continuing to carry out joint experiments with a high speed power line communication promoters' alliance to reduce potential interference to radio communications.

Are you ready for BPL - Broadband over power lines (BPL) is a technique for transmission of high speed data (broadband Internet) over powerlines. Access BPL technology injects radio frequency energy into powerlines which were not designed for transmission of radio frequency energy, and leak substantial energy that causes interference to radiocommunications service

BPL Interference - Zip file taht contains a tutorial section that explains several different BPL technologies

BPL Interference to Radiocommunications - Here are some excerpts from the international radio regulations and fccrules
