Editor's Note

Thanks for your comments. I do review all the articles that come in here and I have been familiar with Hal Walker's work over the years, going back to when he was an invited speaker at a conference I ran, The Wireless Symposium & Exhibition. Yes, it is easily to discredit UNB technology, since it goes against the intuitive understanding that most of us grow up with concerning modulation of any kind, and how it occupies spectrum around a center frequency. And yes, some form of sideband is needed. But the point of the article was to show that it may not be as wide a sideband as typically assumed. It is creative thinking, something we should never abandon.
