True - this all minimizes broadband noise. With a narrow band CW 
system one can end up with a powerful signal at just one frequency 
of course. However, output discharges and gap discharges make 
broadband noise. Anyone who's run a commercial transmitter with a 
sparking aerial would have seen this happening.  Steep discharge 
risetimes are step functions which have a significant spectrum of 
frequencies (theoretically infinite although at some point the power 
sinks below background noise).
