Folks, I have a friend that is looking for a KX3 / KXAT3 (internal tuner) and

If you are interested in this for a KX3 let me know off-line.

There are some cautions in floating a battery with a mains power

switching power supply I am using with my KX3 specifically says
not to use the power supply for directly charging batteries, and
voids the warranty if you do.

Yes, hydrogen outgassing is a potential problem, and the area containing
a normal lead-acid battery should not only be protected from sparks and
ignition sources, but should also be vented to the outside.
I would suggest that you look at a larger gel cell or an AGM battery.

Another problem is that outgasing gases are corrosive and can damage
electronics especially contacts, relays, connectors, pots and the like.

Even if you had an older K3, it's very minor surgery. It's been some

the replacement of two components.

The 1258's are the RemoteRig RRC's required for remote operation, the

I think the answer to your question is a matter of degree.
I do not have any specific test data on the IMD increase as the DC

I would call Elecraft and ask them directly, but I think the 1256 may be a typo
