Phil,

There is no right or wrong way to do it - S-meter readings are arbitrary 
given the S-meter response set into a variety of 'competitors' 
transceivers .  Take your pick and realize the consequences of your 
actions.  If you calibrate it with the preamp off ( which is what I 
would suggest on 40 meters), then the S-meter will be a bit more 
'lively' with the preamp on.  This choice is merely a matter of 
reference.  Bob Sherwood chose to set it with the preamp off, but you 
may like it better with the preamp on - the choice is yours - just 
remember which way you did it so you can interpret your S-meter readings 
appropriately.
