Jeff, et al Looking at your third snap shot, I see what looks like an attempt to create an SSB signal from a clipped sinewave ( or squarewave ) as described by E.W. Papenfus in Single Side Band Priciples and Circuits.. What is needed is envelope limiting and not audio clipping ..

Message-ID: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed At the request of a friend, I looked into this topic a bit last summer. Rather than write a very long post here regarding my testing, I have just posted my observations to my blog: http://k6jca.blogspot.com/ ...where, I hope, you'll find that the inclusion of photos makes the topic more understandable. 73, - Jeff, k6jca _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/ _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
