Please allow me to hijack this thread to ask about low power
draw computers for use with the K3.
Last field day I set up our club's digital station with a K3/10,
SignaLink USB, and a MacBook Pro. The combination worked very
well, but the MacBook Pro, connected through the Apple power
adapter
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:

That one can run Win7-32.

Pignology has a wifi interface that makes an iPad feasible as a
logging/controlling computer. There's a version of Rumlog for iPad, as
well as Pignology's Hamlog. Android tablets reportedly work as well.

Why? Floating Point performance is lousy, and I think that'll show with

I'm using an Atom for one of my IRLP nodes (7962, CentOS 6.4) and file server.
It is mini-itx (small), doesn't use much power (~10 watts) and lowers power

A good example is the Pentium 3 and Pentium 4. The P3 ran at half the
clock speed (or less), but it took significantly fewer clocks to do an

So make sure you read the documentation supplied with the motherboard to

Hi Don,
It's been 5 years since I purchased a computer but the approach I followed
then should still be relevant. If you buy a desktop style PC there will be a

Amazon.com with the same bus nomenclature and you'll be

its a add on.
I use usb to serial cables with my devices and have no issue.

Hi
USB to serial port cables are not like they used to be when drivers were
immature. Now a days, most will work fine.. I have keyspan adapters which have
certified drivers but I also picked up a no name prolific cable that works fine
in XP win 7 and 8.
I would be more concerned about noise
In addition to the Edge Ports I had favorable results with one of these:

Nothing wrong with add on boards. I've fitted a two port to my latest

I built my own last PC, and though it isn't RF-quiet, it's pretty close,

A seller can legally provide an OEM version if you buy it along with

then getting Windows as an afterthought, or spreading your hardware

is an option.
