The K3  was still receiving fine at
the reduced voltage (my low voltage is set at  11V), but the 232 port
clearly was not.

That's similar to the experience I had when operating mobile/rover  using a 
separate AGM battery whose level was somewhere below 12.5 VDC (if I  recall 
correctly). I haven't had time to pursue the problem with Elecraft tech  
support. Clearly, I'm not alone saying the RS-232 port on the K3 sometimes  
doesn't do well below a certain voltage, yet the remainder of the K3 runs just 
 fine!
