Noise Floor Study

| August 23, 2013

A proposal for funding to support the long-term understanding of the RF noise floor has recently been approved by the RSGB Legacy Trustees managing the generous legacy provided by the late Ken Rowell, G5RL.  The funding provides for web support for the Noise Measurement Campaign, announced in the July 2012 edition of RadCom, and data collection for one or more MSc projects at the University of Leicester.  The projects are expected to be run in conjunction with assistance from a small number of amateurs in suitable locations.

The MSc projects will be aimed at understanding the extent to which our radio noise-floor is being raised through the aggregation of noise propagated via the ionosphere from devices such as PLA, switched mode power supplies, etc.  It is also hoped that in conjunction with the RSGB EMC Committee a better understanding can also be gained as to the extent to which amateur band notching actually works.  Further information on the project can be found on the Noise Floor Study page .

John Gould, G3WKL, who drew together the proposal, commented “It is really good to get some work underway to help meet a recommendation agreed at the IARU Region 1 Conference to set up a scientifically valid long-term assessment of the noise floor”.   Gwyn Williams, G4FKH, a co-author of the proposal said “The improved web presence for the Noise Measurement Campaign and the university based research should significantly advance member’s interest and knowledge concerning our radio noise floor”.  Prof. Mike Warrington, Head of Embedded Systems and Communications Group, University of Leicester, commented “As a licensed amateur I can appreciate the value of bringing scientific vigor to this area of research, and at the same time provide me with some worthwhile projects for my students.  I look forward to working with the RSGB.”

The Legacy Committee, chaired by Nick Henwood, G3RWF, is keen to receive other proposals for projects or lasting member benefits that would not normally be funded as part of the Society’s operating budget.
