I have not been on the air from my QTH for a while, but noticed that the K3 interface window now says "Elecraft K3, Smart SDR". I am not sure of the significance of that, but noticed today that pressing "Set rig" on the Spot Log now changes VFO B and not VFO A. I also noticed that not all of the functions work properly in the interface window. I also noticed that Logic stops working after a while and crashes (as it just did as I write this query).
I verified it is not likely to by my setup, as I confirmed all functions using N1MM+. Clicking on the bandmap or typing in a frequency changes VFO A properly.
BTW, using K3 with micro KEYER II, Win 10. All setting checked, baud rate is sync'ed across all devices and software.
It appears that the new interface may be broken.
