<p>Which waveform do you think sounds best ?</p>
<p>SETUP for this test:<br/> FLdigi is sending a text file at 71 wpm from TOM's famous article about qrq cw copy: <a href="https://sites.google.com/site/tomw4bqf/copyingcwover70wpm">https://sites.google.com/site/tomw4bqf/copyingcwover70wpm</a></p>
<p>LINEAR and EXPONENTIAL waveforms were created by the sineCW VST CW KEYER plugin: <a href="http://qrqcwnet.ning.com/forum/topics/home-brewed-software-code-practice-oscillator-vst-plugin">http://qrqcwnet.ning.com/forum/topics/home-brewed-software-code-practice-oscillator-vst-plugin</a></p>

<p>HERE is a picture of each waveform:</p>
<p> LINEAR</p>
