[Elecraft] K3 - am I locked into a specific microcode level

[John Evans]

Why are we using the term microcode here?  When I think of microcode, I 
think of the code within a cpu that takes the machine code from outside 
the processor and turns it into the signals that move and manipulate the 
data within the processor, turning on and off registers and paths.  When 
I think of firmware within a device such as an SDR, I am still thinking 
along the lines of machine code that is outside of some processor.
