Glad to hear that we can count on the K4 maintaining the excellent CW 
characteristics.  I frequently will look at signals I am receiving 
measuring the transmitted waveform based on what I see on the P3 and it 
never ceases to amaze me about how different brands can be identified 
based on the waveform shape and spectral width, not to mention the 
audible key clicks.
