[Elecraft] Power Supplies for K3

[ac5p at sbcglobal.net]

Pete, I have had great results with a marine starting battery (Optima yellow 
top) for past 4.5 years. 

It stays on floor in battery case with 10A circuit breaker in series at positive 
terminal.   A 2 stage 2A charger maintains the battery during receive and off 
time.
Setup is quiet, no heat, and isolated from ac power surges.  I can operate rig 
for several hours a day and have had no problems with high/low voltage.
