I've been running a QRP K2 for about 18 months now. It has the KBT2, and I've been powering the home station with a 10A linear PS that's adjusted to 14.2V, to keep the internal gelcell happy.
Now I'm going to add a KPA100/KAT100 in an EC2 (K2 twins!) and have to upgrade my power setup. My current thinking is to use the Alinco DM-330 switching PS for space reasons (my shack shares space with my office :-) Since this will require an upgrade in my PowerPole distribution setup, and because the linear supply will go back out the bench (leaving some space on the floor), I'm thinking about battery backup, too. I know that the RigRunner folks make a couple of battery backup devices http://www.powerwerx.com/category.asp?CtgID=3580 and I have to admit that I'm tempted to buy instead of build. But I'd like to understand the tradeoffs here. I want to keep the system voltage high enough to keep the KBT2's battery happy. I suppose that I could run the system from a large battery and just trickle/float the battery from a smaller supply ... but that seems a lot more complicated (and harder to keep the voltage up for the KBT2). What have other people set up along these lines? What website should I be visiting? Is the "super" powergate really worth double the price? :-) 73 de chris K6DBG _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
