You can also use one of the digital mode programs which has a spectrum 
display, such as gmfsk.  I found this was also quite useful for 
zero-beating WWV when doing the frequency calibration of my K2 by tuning 
until the tone frequency lined up with the corresponding mark on the 
frequency display.
