K3/100 kit arrived yesterday afternoon (04/17/08) and I started
construction around 2330Z. By 0700Z I was playing around with the 10W version and trying to figure out all of the calibrations. I had not done much reading in the manual to prepare for first use, but I am stumbling through it. I have one question right away. I went through and enabled all of the options that I have installed. When I try to use the auto tuner it tells me it is not installed. Can someone tell me what I am missing here?

Any good ideas?
Presently using an old (and heavy) Yeasy power supply, working very well but - like many others I plan to bring my K3 on trips as well. Anyone tested the MFJ-4125? In that case: How about the noise level? Any other/better low weight switching power supplies? Must say the K3 performs very well and has exceeded my expectations.

Hi
Yes I have used a MFJ-4125 and it is very quiet both RF and fan noise. I also have a 4225-MV and A 4245-MV . The 4225-MV is the same as the 4125 except it has lighted volt and amp meters and a pot on the front panel to adjust the voltage. I use the 4225-MV for a bench supply when I work on radio equipment and The 4245-MV runs my shack, a K3 and a Kenwood TMD-700 2 meter/440 radio. I use Rigrunners and Anderson PowerPoles on everything Thanks Don Brown KD5NDB K3 S/N 0575 Kenwood TMD-700 -------------------------------------------------- From: "Lennart Michaëlsson" <[hidden email]> Sent: Friday, April 18, 2008 7:14 AM To: <[hidden email]> Subject: [Elecraft] K3 Power Supply > Any good ideas? > Presently using an old (and heavy) Yeasy power supply, working very well > but - like many others I plan to bring my K3 on trips as well. > Anyone tested the MFJ-4125?

Lennart,
This is pretty simple issue. I use a variety of power supplies with the K2 and the K3. I like the Astron SS-20 and SS-25. Why? Because I got them for a good price at a hamfest. Nothing special, they just work. I have run Field Day with those on generator power and have had no issues at all. They are light weight and very small. I think any switching power supply that is on the market today would work fine. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

I use an MFJ-4125 for portable operation because it is so small and light.
It is also very RF quiet. For base station use, I use a Samlex SEC-1235M which is also very RF quiet (I have a review of the Samlex power supply on my website at www.ad5x.com). Finally, I also have a Gamma HPS-1a (also reviewed on my website) but it is a little marginal with my IC-706MKIIG. It would probably be fine with the K3, since the K3 uses less current on receive than the IC-706MKIIG - and you can easily operate QSK with the K3.
