[Elecraft] Good experiance using the K3-100 on battery power

[Wes Stewart]

I have a East Penn Deka 92 AH AGM battery in the shack that is on constant charge via a "smart charger" that I built using an Astron RM-35 for the raw DC and pass transistors and an A&A Engineering board that I modified.  A Honda EU2000 outside the shack completes my emergency/FD system.  I have an N8XJK boost regulator on order.

In my shack at home and on Field Day, I've always run my ham gear from 
a big Costco deep cycle battery that is float charged from a little 
regulated 10A supply ($10 at a hamfest). It's a poor man's UPS, and 
works fine. Both the K2 and K3 were designed to minimize current 
drain, but the K3 draws considerably more current than the K2 on 
receive. That's why I'm keeping my K2/100 for use in emergencies.
