I'm using two solar setups. One is a 100W system for the K3 and KX3 / ham station generally. That's probably not going to interest anyone for portable ops with the KX3.
Five or so years ago, I bought 80 4.5-inch wafers from a 2nd tier outfit in New England. From these, I built two panels that supply 21V with no load, and output is about 18W each. The panels were designed to strap on the rear of a backpack and they're about 16" x 28". I've used them only a few times as this transport arrangement is a bit clumsy and maneuvering is difficult with that type of unwieldy backpack load. Now I only use them when I drive the operating location. I would recommend some of the more modern roll-up amorphous silicon PV modules. I've seen them at Field Day, but don't have any brand names. 73, matt W6NIA On Thu, 18 Apr 2013 16:28:52 -0400 (EDT), you wrote: >Rather than reinvent the wheel, does anybody have experience or suggestions >for a small solar array sufficient to keep a KX3 with internal batteries going >during daylight?
