Re: Switching PS with the K3 - thoughts?

Anyone have experiences with the new MFJ-4235MV power supply? We have
been following this discussion because we are always looking for a good
reliable, lighter weight power supplies for our two K3 that we use on
our C6APR DXpeditions.

BTW the K3s are excellent for DXpeditions, light weight, reliable, and
hear/transmit well. We had tried four other rigs.

Ed: I would recommend a switching power supply from Samlex either their 23 amps unit or better yet their 35 amp metered power supply as they are very quiet.

Re: Switching PS with the K3 - thoughts?

Another one that may be worth looking into (other than the suggestions
presented already) is the Alinco DM-330MV Switching supply.

It is metered, adjustable voltage, remotely accessible, small, quiet,
well laid out, and it has a feature similar to Yaesu's "Clock Shift",
whereby you can shift any noise it might make to another frequency; on
the fly.

However, I haven't found any noise from it yet, and the Radio Shack 25
Amp (I believe is a Samlex model) has made some noise when used in my
transportable setup : http://www.se-hams.com/html/emcomm1.html

I am in the process of replacing all of my power supplies with this
Alinco model.

Take a Look: http://www.alinco.com/Products/DM330MVE/

Re: Switching PS with the K3 - thoughts?

The Radio Shack 25 amp supply, which someone else mentioned and recommended
is available on the website, but the local store nearby told me they will
order it for you (at that sale price--$59), and no shipping cost. Most
Radio Shack stores have stopped stocking those power supplies locally. I
already had one, and the Samlex 1223 also, and both work pretty well. By
the way, I did pull the cover off both, and they are not the same--they just
looked very similar. Actually, the Radio Shack supply looks like it might
be a tad more substantial. Anyway, for under $60, it's possibly worth a
look.

Re: Switching PS with the K3 - thoughts?

In reply to this post by Ed K3IXD

I've beent using the Jetstream JTPS28 switching supply with my K3 since Feb '08 and it works like a charm. Weighs in at 4 pounds and never shows any signs of heating up.
