[Elecraft] Enabling FM mode on K3S

[Bob Nielsen - N7XY]

I'm still learning to use my new K3S but am already very impressed with 
the performance.  However, I am unable to switch to the FM mode.  I have 
installed and configured the 13 kHz filter and checked the K3 utility to 
verify that FM is enabled for that filter and that TX FM is enabled, but 
the mode switch will not select the FM mode.  Is there some additional 
step which I have missed?
