[Elecraft] KBT2

[Richard Lim]

Oh one final thing guys, Don KS5NDB was RIGHT. Checked the PS with my DVM
and 14.2V from the terminals, so happy dance, all is good.  I still think
that I'll add Don W3FPR's mod to utilize the A&A smart charger just to be on
the safe side. Gee, how many Don's are there on the list :^) Thanks all.
