Hi Scott,

Part of the source is AGC I believe. Use Slow AGC and Slow QSK and that will 
get rid of a good bit of it. Sidetone keying is another source. If you get 
rid of these two sources, there is still a switching transient which I 
believe is just some imperfections in the audio/QSK interaction.
