I'm going to take a KX3 with me on vacation this summer, and I like to
travel light. I'll have internal batteries for field operation, but
for indoor use, I'm hoping to find a miniature power supply that meets
these criteria:
- very small (say 4 x 3 x 1 inches)
- light weight (less than 1 lb
5A (YES 25A !)
Have fun, and enjoy your holidays

Jameco has a lot of these. Not sure how quiet, but they are cheap enough
that you could buy 2 or 3 and pick the best.

Well, Chief Engineer Wayne, sounds to me like a good idea for a mini
kit !

Yes, the HPS-1a is a great supply. But it's about twice the size and
weight I'm looking for.
A "wall wart" supply would be fine as long as it meets all of the
criteria and is well-regulated.

I have used a MFJ-4103 with my K2 with good results. It's close to your
desired form factor and was quiet on 20 meters (I haven't tried it on other
bands). I also used it on 220V/50Hz in EU.

OK, but it would still make a great mini kit. Especially since there
may not be an acceptable substitute.

This one does look promising, Bob--thanks.
I've also found some possible units at Jameco, which happens to be
about a mile down the road (thank you, N6CM, for reminding me).

Thanks, Randy. This is even smaller than the MFJ-4103.
The web site indicates a noise problem without proper grounding. Have
you found this to be an issue? They mention supplying a "2-pin"
standard power connector, which is *not* what you want if you're
trying to get a good common ground bac

Or consider sticking with batteries using the inexpensive and tiny PST-3P10
charger on the same page at Mtechnologies. I haven't used it but the specs look
good.

Wayne,
When you do find what you're looking for in a power supply please let us know
what it is and how it works out. I'm sure I'm not the only one who'd be
interested in the results of your "research".

Maybe Gamma Research's HPS-1a at http://www.gammaresearch.net/hps-1a.html
will meet your needs.
It's 3.37" x 1.55 x 5.25", specified to provide 5A continuous and 22A at a
25% duty cycle. It weighs 1.25 pounds (which probably doesn't include the
line cord)
I have one for my K3, and it works acce

The power supplies that typically come with external HD enclosures and
external CD/DVD drives should fit the bill quite nicely if they're quiet
enough, generally 12V at 2-2.5A. I've tried several, and havn't noticed
any significant noise with any of the ones I've used.

Hi Wayne,
I expect you are back by now. However it might still be of interest. I have
been using laptop type supplies for this application. Light, small, cheap
and some of them are relatively quiet. They will also fit in a small metal
box. Recently I came across LED lighting supplies, 12V again a
