Yeah it is an oxy moron sometimes... operate off grid using a battery
and you get noise (this will be the internal LiION battery
recharging/regulation circuitry causing it).
Have you tried adding ferrite to the DC leads (and weirdly to the
headset leads, I need to if using ext battery sometimes). You could make
up a simple choke and plug your rig power lead into that, doesn't need
to be in a box or anything... leads from battery then 12 turns of the
power leads or so in opposite directions in parallel on the ferrite (try
FT240-61) to a set of connections to the rig. Or a string of those
little 5mm ID clip on ferrites (ebay) on the Elecraft lead.

A reflector poster mentioned the Maxtron MX 160A for use with the KX3. I
got one off Amazon and tried it. My noise level jumped from S4 to S9.Not
sure how to eliminate it.Nice otherwise.Transmit plug it in. Receive, pull
it out.
