IARU EMC spe­cial­ists Tore Wor­ren LA9QL and Mar­tin Sach G8KDF have sub­mit­ted a paper to CISPR con­cern­ing the increas­ing impact of mul­ti­ple dig­i­tal devices on the noise lev­els in the radio spec­trum. The paper was con­sid­ered at the CISPR Steer­ing Com­mit­tee in May and adopt­ed for cir­cu­la­tion to CISPR Nation­al Com­mit­tee for com­ment as a Com­mit­tee Draft, with a view to it becom­ing a CISPR Report.  IARU hopes that the result of this will be amend­ments to the way in which stan­dards are devel­oped, to recog­nise the need to prop­er­ly con­sid­er the cumu­la­tive impact of mul­ti­ple devices.
