Noise pollution is slowly covering up communications, from AM broadcast stations to the newest digital devices in the Internet of Things (IoT).  While some of this electronic noise is natural,  a growing portion of this nuisance is man-made, largely because of insufficient shielding on popular electronic devices.  Power line noise is another contributing factor, especially on Hawaii Island where salt-laden air, ocean spray, and other corrosive agents play havoc with insulators and transformers on utility poles.

While I was searching for some answers to my noise problem in Laupahoehoe, I ran across this helpful article from the ARRL–“Radio Frequency Interference–RFI.”

The article offers helpful guidance in diagnosing and solving your electronic noise problems.  The article is divided into several easy-to-understand paragraphs, complete with links and various reference sources:

Introduction to RFI

RFI:  ARRL Laboratory Television, focusing on the “Common Point” video program.

Youtube and other video links to RFI solutions.

Full length articles and scientific studies of RFI.

Web links to both amateur and electronic engineering articles relating to RFI.

Information for Electric Utilities.

Naval Postgraduate School RFI Handbooks.


I found the article fascinating with many possible solutions to my electronic noise problems.

Just a reminder to all Hawaii Island radio Amateurs–don’t forget the Hawaii QSO Party from 26 August to 28 August 2017 and the 2017 Grid Madness on 17 September 2017.
