On a related note, since it's been a long time since I asked, is there a
possibility of offering a bare enclosure to match the P3? That size would be pretty good for accommodating a speaker and a power supply capable of driving the K3. Sure would look nice alongside the K-line, too. --Andrew, NV1B .. On Thu, Jun 30, 2011 at 9:25 PM, KC6CNN <[hidden email]> wrote: > I am getting ready to retire.

There's a lot of empty volume in the P3 already. maybe somneone could
build a PS in the same enclcosure as the P3. ...bill nr4c On Thu, 30 Jun 2011 21:37:02 -0400, Andrew Moore wrote: > On a related note, since it's been a long time since I asked, is > there a > possibility of offering a bare enclosure to match the P3?

Bill , maybe the empty volume in the P3 will be used (I hope soon) to accomodate some new features that are "relative" to existing holes in the back panel....I hope ;-). I share the suggestion for a new box with "K Linee" look containing a power supply and speaker(s) as 2 speakers are required to satisfy audio enhancements k3 releases us (AFX for example).73 to everybody - Giorgio

Good suggestion, Bill. In fact this may be what Elecraft suggested a few
months ago (can't remember). Photo in the P3 manual shows loads of space. I'll try to shoehorn a supply in there.

IIRC Eric mentioned a while back that one of the stumbling blocks to offering a power supply is the requirement for Underwriters Laboratories testing and compliance as well as similar certification in other countries and markets - a rather expensive proposition for the volume that would be sold. I leave it to Eric to elaborate (or correct me if I'm mistaken). -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ______________________________________________________________ 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 |

From my experience in the world of pro audio, i can attest to the the expense of complying with safety certifications like this, and I think that Elecraft is wise to steer clear of it. For that matter, I have yet to see Elecraft make a bad business decision. One of Elecraft's greatest strengths is Eric's business acumen. 73, Jim Brown K9YC ______________________________________________________________ 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 |

It might be a good project for one of our home builders to design a project, or
perhaps a repackaging of a commercial product to fit in the P3 case. Since I don't yet own a P3, I am not sure how big that task might be. While I am coming to believe that Wayne and Eric can do anything, they certainly don't have time to do everything and a lot of things that we would like to see would not add to the longivity of Elecraft. The prosperity of Elecraft is certainly in all us Elecraft users best interest.  Willis 'Cookie' Cooke K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart ________________________________ From: Jim Brown <[hidden email]> To: [hidden email] Sent: Sat, July 2, 2011 12:44:43 PM Subject: Re: [Elecraft] Power Supply?

I can attest that obtaining UL, CSA and "foreign" certification for anything that "plugs in" is an involved and costly process. I went through the process a few years ago with a medical product, and I can understand why Elecraft might want to avoid marketing AC PSU's. 73!

How is it any different than plugging in the KPA500 to the ac line/mains?
Elecraft has already done that.

I think that you could possibly put a switcher in the P3 but I don't think it
is practical. You would need a cooling fan in their for a 20 to 25 amp supply and I don't think the P3 is set up to handle a fan. 73, phil, K7PEH On Jul 2, 2011, at 11:16 AM, WILLIS COOKE wrote: > It might be a good project for one of our home builders to design a project, or > perhaps a repackaging of a commercial product to fit in the P3 case.

The KPA500 has plug in power supply. Is there a different standard for a power supply that's integrated vs. a stand alone unit? If the P3 had a 20A switching supply to power itself and maybe an external accessory with a power pole connector output, would that have to be UL listed?

Robb:
... would that have to be UL listed? The answer is yes. Additional certifications would be needed elsewhere in the world. Worse, power line surge and conducted emissions tests would be needed.

Hi Don,
Does the KPA500 have UL certification? 73, Mike K2MK

K7PEH> You would need a cooling fan in their for a 20 to 25 amp supply and I
don't think the P3 is set up to handle a fan. My RS-20M doesn't have or need a cooling fan (though that's in part due to its venting and heat sink, so that needs to be carried over to the P3 enclousre). I'm going to see if I can migrate it to the P3 (which itself probably doesn't generate a lot of heat). If it needs one, fans are small and can sit right on top of the case, fed with 12 V from the supply that will now reside inside.

It doesn't need to occupy table-top space; mine sits on a box under the desk. Same here - but I'd like it more if it matched the P3 enclosure. And now it might... This may be too ambitious but I'll give it a shot and won't be too proud to say "you can say you told me so" if I fail. If it's too much of a stretch to fit a 20 A supply in there, I'll use a supply of less than 20 A, and settle for running less than 100 watts from the K3. When I get a KPA500 sometime in the (distant?) future, I'm sure the stepped-down K3 would still have plenty drive to run the amp at a level acceptable for my needs. Really wish I could just buy a blank P3 enclosure and save all the trouble. --Andrew, NV1B ______________________________________________________________ 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 |

Andrew...
Isn't the RS-20M a linear power supply? I do not have an RS-20M, I have two RS-35M and neither of those have fans either. But, I was assuming that the power supply we have been discussing would be a switcher and contained in a smaller box (the P3 box) so I think it would demand a fan. I have had two other switchers in a box about the size of the P3 and both of them had fans -- noisy fans in fact which is the reason I got rid of them. phil On Jul 2, 2011, at 2:21 PM, Andrew Moore wrote: > K7PEH> You would need a cooling fan in their for a 20 to 25 amp supply and I > don't think the P3 is set up to handle a fan. > > My RS-20M doesn't have or need a cooling fan (though that's in part due to > its venting and heat sink, so that needs to be carried over to the P3 > enclousre).

I really don't understand the hubbub about having a matching power
supply. Mine has never matched any radio hooked up to it and it sits on the floor. I'd hope Elecraft wouldn't waste time and resources on trying to re-invent the pretty much perfected power supply wheel unless they can make a quantum leap in power supply performance, like they did with receiver performance on the K2 and 3. I just don't see it. A power supply is a power supply. They are commodity items. Someone thinks they're going to shoehorn the guts of an RS-20M into a P3? Good luck! I don't think the transformer would fit much less the heat sink. -- R.
