[Elecraft] Band Changing Macro

[Don Nelson]

I am now learning to create macros for my K3.

I want to make a macro that will take the K3 from whatever band and 
frequency where it is and go to the last used frequency on another band, 
say 10m. I have made a macro that will take the K3 to 28.400 MHz. I want 
a macro to take the K3 to 28.xxx where xxx is the frequency where the K3 
was when it was last on 10m.

As a bonus, I would like to have a frequency FIFO (first in first out) 
stack. I doubt that this can be done with a macro or set of macros. But 
it is worth asking none the less.
