Most digital modes done these days require a lot of bandwidth because the signals are being transmitted and received as digitized audio (or worse), and 2. Network delays introduce timing problems inherent in CW work that are not normally apparent in half-duplex digital and audio work.</li><li style="margin-left:15px">Pete will share his thoughts on developing a method to send digital timing information rather than analog audio to the transmitter and use direct synthesis to perform high fidelity modulation. It may be possible to use the descriptive language to code every currently known modulation scheme and then later use the same mechanism for schemes that have not yet been invented.</li><li style="margin-left:15px"><a href="http://www.fairfaxcounty.gov/library/branches/ty/" target="_blank" style="color:rgb(188,54,10);text-decoration:none">Tysons Pimmit Library</a>, 7584 Leesburg Pike, Falls Church, VA 22043</li></ul></li></ul></div></div></div>
