Hi Tom, the K2 works very well from a 12v supply in normal circumstances; indeed, it is designed to run from an internal 12v supply as an option. There are two possibilities that spring to mind from your description of the problem: 1. You may be using a long power cable that is too light

Thomas, I exclusively run my K2 with battery power (oh, I think I've used an Astron RS-20M on it once). I haven't had the problems you are experiencing just because it was run on a battery. Many times from out in the field I use smaller 7 AH gelcells (well, they are smaller than what I

1. You may be using a long power cable that is too light duty for the task and therefore causing a volt drop at the K2. 2. There is RF getting into the power line and causing the distortion you experienced. Thanks for the replies. I am using #12 wire, with Anderson powerpole connectors.

Tom, the #12 cable should be just fine for the K2/100, BUT the battery may be suspect - yes that battery size should be just fine but if you are running at higher power, that battery should allow you operation for about 2 hours if it is in top condition. The condition of the battery may have a

The problem could well be the age of your battery and its aging rise in internal impedance. If it will not charge to 13 plus volts of a fully charged battery, it indicates excessive internal resistance/ age. The fact everything cleared up on an AC to DC supply supports the battery as a

I ran my K2 last weekend on a battery (from my backyard – fully charged 52 Ah. Gel cell), and everyone on the net (40 meter SSB) complained that the signal was distorted and just plain sounded very bad. One person suggested that it was the 12 volts put out by the battery, rather than the
