  Richard,

While "common logic" will say to adjust the spot volume to match the AF 
gain level of the signal to be spotted, that is too much trouble and 
involves a lot of "button pushing and knob twiddling".

A simpler solution is to just adjust the AF Gain control to bring the 
signal down to the spot tone level.  That works no matter where the 
spot/sidetone level may be set.

Try it, it works and is a lot faster than trying to change the 
spot/sidetone level.
