Hi Fred.

The A/B button switches between the two VFOs.  The A=B button sets 
whichever VFO is not the active VFOO to the same frequency as the active 
VFO.  Basically, there are three things you can do with the VFOs.  You can 
have transmit and receive on the same VFO (i.e. have the jSPLIT turned off) 
and switch between the VFOs (that is what the A/B button is for), you can 
split the VFOs (i.e. transmit on one VFO, and receive on the other) by 
turning SPLIT on, or you can force both VFOs to the same frequency by 
pressing the A=B button.  Note that if you have SPLIT turned on, and you 
press A/B, you essentially reverse your split.

Hope this clarifies the difference between these buttons.
