Bob's comment above is right on the money and is well worth re-reading.

Professional announcers use proper mic technique *and* they work in 
sound booths or acoustically inert studios. Sports announcers who must
work in noisy environments use headsets with high quality noise-canceling 
mics inches from their lips, followed by processors far more sophisticated
than any used by hams.

A tip to the phone contest fellows: prepare your CQ loops in a quiet
room well in advance of the event. I am always astounded at the poor
quality of the CQ loops in contests - many from the well known big
gun stations who should know better. I wonder about the impact on the
Q-rate when the listeners (especially those whose native language is 
other than English) have difficulty understanding the CQ loop.
