[Elecraft] blinking SPLIT icon

[Mike Goldstein]

Hello, K3 operators all:

Have you encountered this problem?  You find a DX pileup, find the DX 
station, then determine a frequency where you wish to call the DX. 
However, when you push SPLIT, you find the SPLIT icon, a  mode 
indicator, and the little "down arrow" that points to VFO B are all 
blinking.  Is this a firmware bug you've just found?

Here's the word from Wayne:

"It is not a bug: the K3 is just reminding you that you are about to 
enter cross-mode SPLIT. If you do A>B twice you'll set VFO B's mode 
to the same mode as VFO A, thereby eliminating the flashing icon 
warning. Another way is to use BSET to check what mode VFO B is in, 
and change it if necessary." He adds that this can be stored on a 
per-band, per-mode basis.

Did I ever know that VFO B could be in USB mode, when I assumed I was 
in CW?  I do now!  73 de VE3GFN
