Jeff Stuparits, W4DD, will present “Locating Power Line Noise and other RFI” at the Sci-Tech Amateur Radio Society hybrid meeting on May 13, 2025 in Natick and online.
Description: Radio Frequency Interference (RFI) can be generated from many different devices and can decrease or totally eliminate your ability to hear stations on your HF or VHF radio. In today’s modern world of numerous electronic devices in and around our homes, it’s not a matter of if you have RFI, but of how many devices are generating it and how significantly is it interfering with your Ham Radio receiving ability. RFI can also affect other services like AM radio, FM radio, Over-the-Air TV, DSL Internet, public safety communications, and even cellular telephones. Jeff became interested in RFI about fifteen years ago when it affected his ability to enjoy ham radio for contesting, weak signal work, and QSO’s. In addition to providing information on locating RFI, he will also have a few pieces of hardware for show and tell and discuss how he approaches RFI problems.
