There's not much activity on the bands right now so I'm just sitting here on a
cold rainy day fantasizing about nice weather, lottery winnings, and new ham gear... Something that I would like to see as a new Elecraft product would be a basic 12-volt power supply. Specifically a switching power supply with no RF interference problems, simple metering (analog or digital) to monitor voltage and current, and a box that matches current Elecraft rigs. I'm strictly a QRP guy so something small would keep me happy, but a little more beef for the QRO people would be OK too. Now, what will I do with that million dollar lottery prize? ... 73, Paul - N8XMS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Cold and rainy here, also...
Actually, I would love to have such a P/S built into my base K3. (Yes, the K3 is very light and portable; except not so much when you have to bother with PS, cables and cord). With a built-in PS you wouldn't need any meters or box and could use a standard line cord instead of cables, APP connectors, etc. (Would require a new back panel for the K3, i guess...) This would be more convenient to transport, even for just around the house when you'd like to do some SWLing in different rooms at a moment's notice. (A MW loop antenna might be nice also...) 73, Drew AF2Z On Fri, 08 Apr 2011 13:16:44 -0400, you wrote: >There's not much activity on the bands right now so I'm just sitting here on a >cold rainy day fantasizing about nice weather, lottery winnings, and new ham >gear... > >Something that I would like to see as a new Elecraft product would be a basic >12-volt power supply.

Just in case you haven't looked, the inside of a K3 is filled up if
you have the 2nd RX and the 100W KPA100. IF they could put a 25 watt PA and a power supply in the same space as the KPA100, you could use the KPA500 if you wanted more than 25 watts. Or, all you folks that got P3's, any room in the back of the P3 for a power supply? 73, Guy.

Still raining...
I wonder if a small switching supply module could be designed into the space occupied by the PA, and having a standard line cord on the back panel of the module. Just for us low-power K3'ers. I'd sure like to have one. I guess it depends on the potential market size (How many non-PA K3's are there in circulation anyway?....) 73, Drew AF2Z On Fri, 08 Apr 2011 16:12:11 -0400, you wrote: >Cold and rainy here, also... > >Actually, I would love to have such a P/S built into my base K3.

Hi all.
I like the PS idea for both the K2 and K3. What I was thinking is that there is no space inside both of the cases with options installed but if they could design a screw on bottom section with the PS in there. Yaesu has something like that and it is only around a inch tall when added with no fan and runs cool at 100 watt's. I don't see why a small housing couldn't be manufactured to bolt on to the bottom. I don't know about the K3 but the K2 looks like it could be done. Just a thought. 73 de W2EEC Eric ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Threads like this one about power supplies must make both the
transceiver manufacturers and power supply manufacturers gnash their teeth and give up in despair! The market already contains a number of very small, interference-free supplies that fit this idea: Pyramid, for example makes a 30 A. 13.8 V. switcher that measures 8"X8.5"X2.5" that sells for a reasonable price, and Tandy also sells one, slightly smaller, that delivers 20 A. I have three of these, quite a bit smaller than a K2, that work beautifully. They sit about 4" from my K3 and my ICOM 910H, and produce no discernible interference whatever. There may be a need for a much higher capacity switcher -- I have not been able to find one that would replace my 2-ton-Tessie Astron 70 -- but the low end is very well covered. It seems quite counter-productive to shunt high-quality transceiver engineers into the power supply business...the K3 is nearly unique, ditto for the KPA-500, but it looks to me that the power supply issue is pretty well covered. Maybe Elecraft should just sell a "meatball" decal emblem for use on third-party power supplies?

How about Elecraft's commissioning one of the PS manufacturers to design a
package to fit into a P3 enclosure.

The "idea" is to get rid of the extra box, cables and connectors: just
a line cord to the back of the K3 providing a more transportable low-power or receive-only setup. Seems kind of elegant to me... 73, Drew AF2Z On Fri, 08 Apr 2011 17:11:03 -0400, you wrote: >Threads like this one about power supplies must make both the >transceiver manufacturers and power supply manufacturers gnash their >teeth and give up in despair!

One could build a resistive load into the box, thereby avoiding the
antenna coax. Also, one could disconnect the microphone and remove all the knobs, etc. from the front panel! How about just potting the whole thing in concrete?

Hey John.
Good idea :-) I like concrete. I see what they are talking about. I also have a Yaesu 897D with an attached tuner and a power supply. It is a very nice and portable package that I take up to my camp with me. When I get to camp all I have to do is plug in the antenna and the power cord. My camp is small so less is better. That is why I was suggesting something similar for the K2 and K3. I know I would make good use of it. Sorry if you don't like it but it may not be for you. Portably and quality is a big reason why I am switching to Elecraft and to have a PS in the rig its self would be awesome for me and it sounds like others would like it too. Just a suggestion for the "New Product Suggestion" thread. 73 de W2EEC Eric ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

At our mountain top locations, we have been using the various current capacity models of the supplies from http://www.iotaengineering.com/dls.htm and have found them to be excellent for many years of service. We use them to float charge LARGE battery banks at 12 VDC. They provide tremendous capability in a very small, highly efficient package. The 70 Ampere units have been extremely good for float charging 2,000 + Amp Hour battery banks.

PowerWerX Model number SS-30DV is a switch mode, 30A very small supply and I
have 2 of them here and NO RFI issues, stable at 13.8VDC. It even has a very silent fan plus Anderson plugs (2) on the front with Lugs on the rear plus the Red and Black nuts de come off so you can attach ring tipped wires and/or spade types.

Dave,
Selling re-branded items is a "bag of worms" in many cases. The re-brander must take full responsibility for any warranty issues, and the re-brander is at the mercy of the originator for providing a quality product that meets specifications. There has been enough discussion about the Elecraft USB to serial adapter ( the previous Prolific adapter) that everyone should heed - let's not pass that same legacy on to power supplies. Some things are outside the control of Elecraft and the subtleties of "specmanship" may miss the eyes of even the most conscientious engineer. I cling to the KISS principle - let each manufacturer be responsible for his own product. The integration of other manufacturer's product (like the K3) should be done first on the specifications, and secondly on endorsements of other manufacturer's products.. 73, Don W3FPR On 4/8/2011 8:13 PM, David Gilbert wrote: > I totally agree.

Heh, heh.... OK, great. You've convinced me of the desirability of
having as many extra boxes and cables in my shack as possible. That is really what ham radio is about. So now I'll suggest that Elecraft redesign VFO-B as an outboard box with five or six cables to attach to the K3. Maybe add a big outboard knifeswitch for power on/off and a standalone Jacobs ladder for the benefit of those too technologically jaded to be impressed by a mere tangle of wires and jumble of boxes. 73, Drew AF2Z On Fri, 08 Apr 2011 18:06:46 -0400, you wrote: >One could build a resistive load into the box, thereby avoiding the >antenna coax.

The "Elecraft" Bencher HexKey seems to have worked OK, I have one. But
if I were running a company, I'd be with you Don. I think most of us know that data sheets and specifications never ever tell the whole story about a product. 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org On 4/8/2011 6:43 PM, Don Wilhelm wrote: > Dave, > > Selling re-branded items is a "bag of worms" in many cases.
