No.  LSB => signal transmitted is on the lower side of the carrier.

Subtract 2125 Hz from the indicated carrier to get the on the air 
frequency of mark.  That is, if your AFSK generator is producing 2125Hz 
for mark.

Actually, you probably want to decide where to put your mark frequency.  
In which case you would add the 2125Hz to get the frequency at which to 
set the carrier.


It is good to hear about some real activity.  Unfortunately, I am not 
ready to participate.
