U.S. Federal Communications Commission rules for broadcast station transmitters (sec. 73.1215) require that the full scale range of a linear meter be no more than five times the lowest normal indication being measured, i.e. readings must be more than 20% of full-scale to be relied upon, and meter accuracy must be greater than 2% of full-scale. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
