[Elecraft] Thoughts on internal vs external ATU for K3

I used my K3 with built in matching unit directly into a low (avg 10ft agl) 
doublet of 88ft per leg (somewhat bent) and a short feeder directly into the 
PL.   No rf earth, isolated mains supply.  Worked well across 160 to 10.  I 
should have used a coax choke but it worked very well.  It has always been 
tedious using an external manual tuner with other rigs.  It well justifies 
the $ for instant band switching.
