The test for *conducted emissions on the mains lead* goes up to 30 MHz. Emissions at higher frequencies are controlled by the requirements for radiated emissions. The lead is long enough to radiate reasonably efficiently above 30 MHz. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
