Sideband Suspicion

I was disappointed to see the article "Sidebands Are Not Necessary" (August 2011). This work has been debunked in several places, one of them being a good article on the web by Phil Karn. As the published article makes a rather outrageous claim, "sidebands are not essential for transmission or reception," it deserves a lot of scrutiny before being published. Please do a better job of reviewing articles.
