I went to Harbor Freight yesterday during lunch to buy a 15" soft tool bag that I had a coupon for. The purpose of the bag is to haul around the disassembled pieces of my magnetic loop antenna.
While I was there, I started walking up and down the aisles, looking and knowing I had a 20% "off" coupon in my pocket. You can get into a lot of trouble this way, but I got myself into only minor trouble, I guess.
I purchased one of these:
It's an attache` case sized solar panel with 12V and 24V - (unregulated) outputs. It's rated at 13 Watts. This will be head and shoulders above the mini panels that I use now for charging 12V SLAs. Knowing the output is unregulated, I then proceeded over to Banggood and picked up one of these:
So not only will I be able to charge deep cycle batteries in an environmentally friendly manner (we all gotta do our part!); but I can even run the KX3 (after mucho testing, of course!) off the panel for Field Day as this little unit will regulate the panel's output to a steady 12V.
Both units ran me less than $75.
