Approaches to Tackle Noise Problems Vary, Remedies Elusive 03/03/2021
RF noise is a frequent discussion topic among radio amateurs. A proliferation of electronics has cluttered and complicated the noise environment; it’s not just power lines anymore. Unless isolated from civilization, most hams experience RF interference (RFI) sometimes without even realizing it, although spectrum scopes on modern transceivers make RF noise much more apparent. Various approaches to address the apparently worsening noise floor have been taken around the world, some addressing lax regulation.
“We all want to enhance our ability to copy the weak ones by increasing our signal-to-noise ratio,” Alan Higbie, K0AV, said in his March/April

Preparations continue on the part of the International Amateur Radio Union (
IARU) to represent the interests of the amateur and amateur-satellite services at World Radiocommunication Conference 2023 (WRC-23). The International Telecommunication Union (ITU) sponsors WRCs, typically every 4 years, to consider revisions to the international
Radio Regulations that define frequency allocations for various radio services.
“As an incumbent radio service with allocations at intervals throughout the radio spectrum, the amateur service faces challenges at every WRC,” IARU Secretary David Sumner, K1ZZ, said. “Successfully defending our existing access to the spectrum is a significant accomplishment at any WRC, but sometimes it is possible also to improve our existing allocations. WRC-19 resulted in major improvements in 50 MHz allocations in Region 1. Without any doubt, this could not have happened without the

SRAL is asking for amateur radio privileges on 220 – 225 MHz as a replacement for the 1240 – 1300 MHz band, which was deleted last April 24, except for use by special permit. SRAL’s initial request for 902 – 928 MHz was turned down.
The request is to provide spectrum for Amateur Television (ATV) operation. The special permits for the 1.2 GHz band will expire when the Galileo GNSS (GPS) constellation becomes fully operational. Concerns have arisen in Europe regarding the potential of amateur radio interference to one Galileo frequency.
