P3 Ser. No. 1327 arrived about 8 minutes ago. Several minutes were
needed to cut through the tape on the packing...packing very high quality...nothing for the elephants, thanks be! About 2 minutes needed to connect up...had to get my PR6 out of the way, and will cope with its power feed later. Ergonomics excellent. Panel controls completely obvious. Display MUCH better than I had expected from the advertisements...no blockiness, no jaggies. A quick search on "brightness" in the PDF manual brought up the display brightness control. One complaint in this paean of praise -- since the 13.5 VDC out on the K3 back panel will simultaneously support both the P3 and the PR6, one or the other of those RCA plugs should have been a pass-through, or there should have been a pass-through on the P3, since both units are useful. All in all, I am very pleased with the P3. Thanks to Elecraft for another winner.

John, build or purchase an RCA Y connector. I use one to power both my PR6 and P3.

I do think it's a serious consideration. First, it seems easy to do. Second
the K line has one of the most intelligent powering schemes I have seen. You can power on from one switch or each individual unit. As for daisy chaining... I wouldn't. Just put a dual RCA on the K3. Since they are used for stereo, dual jacks are cheap and abundant.

The current available from the K3 DC output jack is limited. A PR6
and a P3 just about max it out. For those who want to turn multiple 12 volt powered accessories on and off with the K3, drive the coil of a 12 volt relay from the K3 DC output jack and run the power supply feed through the relay contacts. Lots of devices can then be turned on/off with the K3. That is the most sensible solution IMHO, no worry about overloading the K3 12 volt output. A little enclosure to hold the relay and several RCA jacks or other connector of your choice is an easy project to construct. 73, Don W3FPR On 5/3/2011 9:52 AM, Phil Hystad wrote: > On May 3, 2011, at 5:48 AM, R.

From the owner's manual for the K3, the DC power output is rated at
0.5A max. The P3 max draw is, you guessed it, 0.5 A max. this doesn't leave a lot of overhead for 'all' the other things you want to power with it. ...bill nr4c On Tue, 3 May 2011 01:43:09 -0700, Fred Townsend wrote: > I do think it's a serious consideration.

I would disagree on being the 'most reasonable' [fix]. However I do think
the relay solution is a good one if you are planning on plugging the 12 V coffee pot in. I think this issue is the classic glass half empty or half full. There are really two issues: 1) A field Fix 2) A wish list for feature products As for #1 the Radio Shack solution is a good but one should apply the appropriate Murphy law that being the probability that the Radio Shack appliance will be forgotten on any field day is directly proportional to the distance to the nearest Radio Shack. If FD is held at RS then the appliance will be remembered. If FD is held in the Yukon Territories the probability the appliance will be forgotten is 99.9%. Ask any FD chairman! As for #2 yes it will require a change to the PCB, the sheet metal, two manuals, BOM, and possibly the fuse rating. I still think it's easy to do. To do being on the next clean up run of the PCB. Easy does not mean insignificant. de Fred, AE6QL -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Don Wilhelm Sent: Tuesday, May 03, 2011 7:02 AM To: [hidden email] Subject: Re: [Elecraft] Pleased...P3 No. 1327...

That seems a bit bizarre to me. The K3 has speced the DC output at
0.5 Amps. Now some users want to draw 0.6 amps from that output, and it seems to me that "this is a fault of the K3" - that is nonsense. As a parallel, many household AC receptacles are rated (and enforced by the circuit breakers) at 15 amperes. Now, we want to draw 20 amperes from that receptacle - who is to blame when the circuit breaker trips - the electrician or the user. I think the answer is obvious even to the casual observer. Use the 12 volt DC output from the K3 within its specifications and no harm will come. If you want more than it provides, use some different scheme, blaming the K3 design because it is not what you desire is just not responsible IMHO, and asking for changes in that aspect of the K3 is just not reasonable. Changing the sheet metal of the K3 and the fuse and the board layout just to satisfy a few is cost prohibitive for the benefit gained. Why should Elecraft need to provide for more DC current output than is required by Elecraft provided accessories (the P3 and the PR6). Work with what you have - even if it involves adding a relay to power your chosen accessories. 73, Don W3FPR On 5/3/2011 9:41 PM, Fred Townsend wrote: > I would disagree on being the 'most reasonable' [fix].

In reply to this post by Fred Townsend
Interesting how my original comment specifically about powering the PR6
and the P3 generated such a wide spectrum of (dare I say irrelevant?) responses! First, I agree that an RCA "y" is a reasonable fix. I don't happen to have a RS store close by, and to order a "y" seems unreasonable, at least until I have some other items to add...I can get along without the PR6 until then...when 6 is open, attenuators are more in demand than preamps...in the day-long opening on 4/27 I ran almost all day with the attenuator "in." Second, I don't plan to plug in the coffee pot or an electric blanket, just the PAR6 and P3. I do not like the idea of adding yet another little box to the collection I already have, to accommodate a 12 volt relay and jacks. If I wanted to do this, I would just connect the PR6 to the K3's power supply directly, as it is usually "on" when the K3 is on. Third, it might be just as easy to drill a hole and mount another RCA (or whatever) jack. The reason to NOT do this turns on whether Elecraft would touch one of their units that has been "violated." I recently had a very negative interaction with TenTec who refused to repair one of their boxes because it had an extra power outlet installed in the back apron..."custom modification, yatadda yatadda..." I have nothing against coffee pots. John Ragle -- W1ZI ===== On 5/3/2011 9:41 PM, Fred Townsend wrote: > I would disagree on being the 'most reasonable' [fix].

I'm surprised that RIGrunner or MFJ or somebody doesn't make a 12V
distribution system with a remote on/off control that could be connected to the K3 switched 12V output. Sounds like an opportunity: Someone on the list should market one. Or at least design one and write a QST article. Al N1AL On Tue, 2011-05-03 at 10:01 -0400, Don Wilhelm wrote: > The current available from the K3 DC output jack is limited.

It's actually a piece of cake. If power for the control relay came from the external supply and not the the K3 and the relay coil was controlled by an transistor or FET, one could control the strip with: 1) +12V from the K3 2) +13.8V from most Yaesu rigs (+13.8V RCA or "Band Data" jack) 3) +13.8V from the ACC jack on most Icom rigs 4) +5/+8V from the mic jack of most Icom/Kenwood rigs 5) +13.8V from most Ten-Tec rigs 6) +5V from a computer USB port! I may even have the design for such a beast around someplace. 73, ...

Yup, it would be a simple design. For best reliability I think I would
probably use a power MOSFET instead of a relay but either would work.

OK Joe,
When do we expect a release and order date?....Grin Cheap (not cheep) Joe ok? I would make one but a visiting K3 owner let the smoke out of my soldering station and dumped it in the bin...:-( 73's Gary On 4 May 2011 15:32, Alan Bloom <[hidden email]> wrote: > Yup, it would be a simple design.
