It would be interesting to see how much IMD it takes to significantly 
increase key clicks of a "clean" keyed CW signal, like that of the K3.  
I'd expect the effect to be small, compared to that on an SSB signal for 
the same level of IMD, but I could be wrong.  I suppose a simple test 
would be to have a local friend with a P3 watch the signal as I turned 
down the supply voltage on my K3.  Has anyone tried anything like that?
