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

I ran my K2 last weekend on a battery (from my backyard â 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
