I just measured my fully-loaded K3/P3. They draw 1.94A on and 4.3 mA off.

I recently set up four solar panels and a pair of 6V golf cart batteries to run my station. When I first set it up 6-8 weeks ago I was getting 35 Ah per day. Now with the sun lower in the sky and the panels shaded by my tall trees, it's more like 25 Ah/day. The batteries didn't seem to be holding a charge, and I thought they might be defective. Then someone noted that K3s pull some current when they're switched off, so I just measured mine. Sure enough, when switched off, my oldest one is pulling 420 mA and the next oldest one is pulling 350 mA. The combined load is 18.7 Ah/day! That load, combined with a a few hundred mA for antenna switching relays is what's draining my batteries. Is there a fix for my K3s short of an external switch to disconnect them from the battery? 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
