Good radio reception is all about maintaining the highest possible signal to noise ratio at the receiver, but the electrical grid can be a potent generator of radio frequency interference throughout the amateur radio bands. Add to that, the widespread application of switching power supplies in products ranging from cell phone chargers to washing machines to HVAC equipment only adds to the sea of RFI that Hams have to deal with.
Jeff Stuparits, W4DD, has years of experience hunting down RFI. During this time he has developed a suite of tools and techniques for hunting down radio interference, and has learned that developing a good working relationship with the power company and the neighbors is critical to resolving RFI problems. Jeff tells all in this presentation from the Antique Wireless Association's "AWA Shares" program.
