[Elecraft] size of radio limits? - K3

[Don Wilhelm]

No wonder I was being confused by all this - HEY, if you can access any 
of the 4 memories randomly, then it is no longer a 'stack'!

 From what little programming I learned, a 'stack' is accessed only from 
the top - you stuff things into it, and then remove the topmost one, 
throw it away if that is not what you wanted and do it over again until 
you have the correct one.  (OK, my mind goes back to the 8080 PUSH and 
POP instructions).

If it were me, I would have named them something like 'In-band memory' 
rather than 'Band Stacking Memory', but I guess there is some precedent 
for that name.  In any case, I am glad that the K3 offers random access 
for these memories.
