I have the Micronta 22-124A 13.8 at 2.5a... that would sure do it very well.
I've run it on my K2 and about anything else that needs 12 v. --... ...-- Dale - WC7S in Wy > From: [hidden email] > Date: Tue, 27 Jan 2009 18:33:03 -0800 > To: [hidden email] > Subject: Re: [Elecraft] AC supply for KX-1 > > > On Jan 27, 2009, at 4:41 PM, [hidden email] wrote: > > > I'm looking for a very small, lightweight 110/220 supply for the > > KX-1.

The comments on Eham.net are very bad, due to the noise and hash that
PS develops (MFJ-4103). Hope this help.

I have not experienced any noise issues with mine, but possibly there
are variations between units (not an unknown occurrence with MFJ equipment). I have mainly used it on 20 meters and up so don't know how it might do on 160 or 80 (noise issues are often worse on the lower bands). Milestone Technologies (N1FN) sells the CUP36, a similar supply which is popular among QRP operators <http://www.mtechnologies.com/cup/>. The web site indicates their tests showed it to be pretty clean, but the only review on eham.net mentions noise problems with that supply. I searched a bit before buying my MFJ-4102 in 2004, hoping to find one that put out a little higher voltage so I could use it only to charge the internal battery in my K2 (which would avoid hash issues), but was unable to find a suitable supply at that time. 73, Bob, N7XY On Jan 27, 2009, at 10:49 PM, Sante - IK0HBN wrote: > The comments on Eham.net are very bad, due to the noise and hash that > PS develops (MFJ-4103). > Hope this help. > Sante > > > At 03.33 28/01/2009, you wrote: > >> On Jan 27, 2009, at 4:41 PM, [hidden email] wrote: >> >>> I'm looking for a very small, lightweight 110/220 supply for the >>> KX-1.

Dave,
I don't know what your intended use is, but may I be bold enough to suggest you use a small SLA battery and keep it topped off with a low current battery charger. I know that does not conform to lightweight, but it certainly will provide all the power the KX1 will need, and it should be good clean power. 73, Don W3FPR [hidden email] wrote: > I'm looking for a very small, lightweight 110/220 supply for the > KX-1.

I have to second this idea - dollar for dollar you aren't going to get any cleaner power than a little battery. I use a 7.2ah battery for my KX1, which I can bring outside, bring on the trail, or use anywhere in the house... will last nearly forever. Even a small 3ah would last a heck of a long time, and would also be useful for other radios/projects. I use a battery tender plus, but I'm sure you could get a cheaper charger to do the job.

Yeah - Batteries Plus is a good source for AGM batteries. You may have one in town, else you could order online. The battery I have is the Werker 7.5ah:
http://www.batteriesplus.com/pc-32634-32634-WKA12-7.5F.aspx You can get quite a smaller capacity model as well to save weight and $$$. They sell Werker brand AGM battery chargers, you will find those on there as well. However I have a Battery Tender Plus which is a bit pricier, but I use it for my motorcycle batter as well.
