well look at a netbook . or a small tablet pc and use a external
battery and not a inverter.
I have talked to people that use as netbook and a 12v 7Ah batt and spend
almost 9 hours contesting.
and on a 12v 17Ah deep cycle marine battery. you can go a day or 2 with
a kx3 and a netbook.
You might try the various automotive multimedia PCs. All of them are
12V, and some have pretty decent power savings modes.
Here's an example from Mini Box:

I read the two posts about the MFJ loop antenna and thought I would add my own

Years ago, I bought a MFJ 36” loop with the remote tuner and while it worked

weakest signal
I did this mod, and I recommend it, it really makes a difference for hardly
any effort. It is by the way the first mod for the K2 for years!

Great idea, I can see it working without doing it. Should also work nicely

About the KX3's panel: are its screws self-contained, or are there loose
nuts behind the cover? I don't want to do something stupid.

I'll assume you did not assemble your KX3. The screws that hold the display
bezel on thread into standoffs attached to the control board. IIRC, the 5
screws that hold the bezel (4 around the display, one below the VFO A knob)
are the only screws that hold the control panel in place. Use caution
I would appreciate knowing the experiences of folks who have run their K3 on
battery power for several (4-8?) hrs., with perhaps a 20% TX duty cycle. What

Paul,
you will get more meaningful replies if you state what power level for TX.

It's not quite that simple, Arno. Those screws go into F-F standoffs that
mount to the pc board behind the panel. In addition to the four visible
screws there is a black flat-head screw under the tuning knob.
Complete details of the assembly are in the Kit Assembly manual. You can
download it
Paul,
You did not say whether that is a K3/10 or K3/100 and whether you have
the extra current draw of the subRX, nor what your transmit power level
would be, so we cannot give you a realistic answer.

Think of diversity as removing the Sub RX from the VFO-B knob. When in

So you should be good. Turn on Split, Lock VFO-B to maintain
