Re: [Elecraft] K3 on 6M
If anyone needs the external 6m preamp for an original K3, I have one I would part with for a reasonable price.

Re: [Elecraft] [K3][P3] 6m Preamp and P3 on AUX Pwr
Yes. The 12 V aux current should be kept below 500 mA, and the P3+PR6 should be well below this.

Re: [Elecraft] [K3][P3] 6m Preamp and P3 on AUX Pwr
I would think we users are getting to a point where a good, automotive relay designed for continuous duty usage would be a good idea here. Simply use the 12v auxilliary power to feed the coil of the relay and let the contacts of the relay feed power from our 12v supplies. I don't remember the stock numbers of the parts, but we used these in an oilfield industrial application a few years ago and had VERY few failures, and when we did, they were readily available local to the unit being used. They have a multitude of mounts so they should be easy to integrate into the shack. That's the route I plan to take, that is if the relay pulls less than 500 mills, hi. 73, Don, WB5HAK __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] [K3][P3] 6m Preamp and P3 on AUX Pwr
For that application even Radio Shack has 2. Numbers 275-226 275-218. My local NAPA store also had them in blister packs but I have not checked in awhile. They were a little more in cost than Radio Shack. A relay in this usage is a mechanical current amplifier. 73, Bob K2TK On 8/21/2010 1:09 PM, Don Cunningham wrote: I would think we users are getting to a point where a good, automotive relay designed for continuous duty usage would be a good idea here.

Re: [Elecraft] [K3][P3] 6m Preamp and P3 on AUX Pwr
I went to radio shack and got the relay I needed. I then built a box that will pass 10A to several RCA connectors (I wanted to be able to plug the units plugged into the box into the K3 when portable with a sub set of my goodies). Anyway I then also got a few of the cheapy cores that Radio Shack has there. I put an LC filter on each port just for fun... I figured if I was making it it only takes a short bit of time to put some RF filtering on each port... I also stuck a couple big bulk caps in there just for grins. Then an LED to signify that its on too (why not...). Finally installed a suitable cord with an APP on it to supply the 10A of power. All in all its a useful little box and every piece of it can be had at Radio Shack still today. ~Brett On Sat, 2010-08-21 at 12:09 -0500, Don Cunningham wrote: I would think we users are getting to a point where a good, automotive relay designed for continuous duty usage would be a good idea here.

Re: [Elecraft] [K3] K3 6M operation
I will add my voice to the unanimous use a preamp crowd. I also run the PR6 on 6M, and agree it's an excellent preamp. It also integrates seamlessly with the K3, which isn't the case with a third party preamp. More often than not I also run the internal preamp as well. The internal preamp by itself typically isn't sufficient to make weaker signals copyable. When the e-skip signals are pounding in at 20 or more over 9, then I will back off the preamps as they're not needed and the extra gain overwhelms the front end. 73, Lou, W0FK rfenabled wrote: Hi, Well I just completed my first 6M contest this past weekend and found it quite good. There was some time ago a lot of comments on the K3's sensitivity on 6M. The result was Elecraft produced a pre-amp and not much comment has been seen since. If anyone on the list is a 6m operator with a pre-amp it would be good if they could contact me off list and let me know what they think of running with or without the pre-amp... I don't wish to clog the reflector with this topic.
