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.

Any magnetic fields nearby? A standby charger on the GelCell perhaps?

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
