[Elecraft] K3 - use of a Clear Speech unit

[Bill W2BLC]

I keep reading about the Clear Speech units and wonder if they are a 
viable addition of the K3? Any have user comments from experience or use 
of these? I am looking for the silver bullet that cleans up lightning 
static.

Always on the prowl to improve my "armchair copy" station.

Thanks,
