[Elecraft] K3 VFO split problem

The mode on VFO B is USB or LSB (look at the mode indicator 
in the LCD while holding the REV button).  This is a side 
effect of the K3's failure to copy the mode to VFO B on the 
first tap of the A->B button. 

In order to keep both VFOs on the same mode, you need to tap 
A->B twice.  The first tap copies only the frequency and the 
second tap copies everything else (mode, filter settings, 
antenna selection, etc.). The failure to copy mode has been 
loudly debated several times.
