[Elecraft] K2 Battery Charging System With out Mods?

[Don Wilhelm]

Tom,

The charger that the A & A Engineering Smartcharger is based on appears 
in my 1994 ARRL Handbook at 27-16.  It claims to be an update from the 
original article by Warren Dion N1BBH which appeared in June 1987 QST.
It uses the Unitrode UC3906/UC2906 charge controller.

73,
Don W3FPR
