That's easy if you are trying to tune against a continuous carrier, but 
you are normally tuning against a signal that is being 100% amplitude 
modulated at about 10 to 30 baud (12 to 36 wpm).  It gets quite 
difficult to separate the amplitude modulation from the keying from that 
from the beating.
