[Yaesu] display offset

   I don't know the rig, but my FT-990 can display the frequency two different 
ways, the actual emission frequency (of the CW signal, for instance) and the
canter frequency, the frequency of the suppressed carrier, between the U and L 
sidebands.  It is changed by turning the power on with a particular button held 
down for each choice.
