Elimination of Electrical Noise from 30kHz to 30MHz
By Don Pinnock, G3HVA
Many radio amateurs experience electrical noise problems and feel forced off the amateur radio bands. Don Pinnock, G3HVA is a firm believer that radio amateurs should deal with the problems rather than not be forced off the air.

RadCom EMC column archive
RadCom is one of the most respected amateur radio publications in the world, and over the years has published many articles on EMC issues.
Here the RSGB has collected all EMC articles published in RadCom since June 1989 to form a unique and valuable resource for the Society’s membership.
Please note that you have to be a member of the RSGB to read the articles, and initially, on clicking a link, you will be asked to log into the Members’ Area of the RSGB website. After entering your user name and password, the article will load, and you will not be asked to enter your user details again in the same browsing session.
All the articles here are presented in Adobe PDF format. Some articles are quite large files, so please allow time for them to download.
There will often be more than one EMC article in each PDF file, so you may need to scroll down through the file to find the subject you are looking for.
A large text version of this page is also available.
