To fit the sub-rx you have to remove the front panel, take off the dsp 
board and fit the auxilliary dsp board.  It then goes back on.  I have 
fitted (and in one case back engineered and refitted) 3 sub-rx's now 
with zero problems.  The only reason I had to back engineer one was for 
a problem that occurred that was nothing to do with the sub-rx.
I always recall Elecraft telling us that the sub-rx required some work 
on the radio and as it got closer they also showed us it in photographic 
form.

The point is the fit is straightforward.  If you built the K3, it is 
almost trivial in comparison and works really well!  The K3 is a 'kit' 
and occasionally you might have to do some work on it just like the K2.  
In fact some of the stuff on the K2 (like the 60m board) required some 
mods to the main rf board.

My advice to anyone contemplating the sub-rx fit is just to do it.  It 
enhances the radio and is not difficult to do.  Your enjoyment of the 
radio will increase, especially if you have a vertical and a horizontal 
aerial for the same band in diversity mode!
