Good Evening:
If I was to add an external speaker to the K3 what would it be, looking for suggestions as Dayton is just around the corner. 73 Bruce N9BX K3 # 775 _______________________________________ No viruses found in this outgoing message Scanned by iolo AntiVirus 1.5.3.5 http://www.iolo.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Bruce,
The K3 offers 'stereo' with the subreceiver, and the AFX effects when selected (without the subreceiver too). So I think the best external speakers are moderate to good quality computer stereo speakers. I bought a pair for about $25 at Staples and they serve me adequately. For mono only external speakers, the Motorola communications speakers are a good choice. 73, Don W3FPR Bruce Osterberg wrote: > Good Evening: > > If I was to add an external speaker to the K3 what would it be, > looking for suggestions as Dayton is just around the corner. > > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi Bruce,
For communications bandwidths, a sturdy 4-ohm, 3 or 4" diameter mobile speaker (non-powered) does a great job. For a bit more fidelity and to take advantage of the K3's stereo speaker outputs, I use a pair of good quality bookshelf-style speakers (again, non-powered). Right now I'm using Best Buy's "Insignia, 4-inch, 3-way surround speakers," which sound quite good, although they're 8 ohms rather than 4 so the available per-channel peak power will be lower. They're about 4"W x 8"H. I had been using just a single speaker, but having two allows me to get L/R separation of the main and subreceivers, as well as take advantage of the K3's "AFX" simulated stereo mode. 73, Wayne N6KR On May 3, 2008, at 7:05 PM, Bruce Osterberg wrote: > Good Evening: > > If I was to add an external speaker to the K3 what would it be, > looking for suggestions as Dayton is just around the corner. > > 73 Bruce N9BX > > K3 # 775 > --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Wayne, I'm curious about what seems to be an emphasis on "non-powered"
speakers in your reply... why? My op bench was getting overrun with speakers for various rigs. I picked up an 8 channel stereo line level mixer and now run everything through a single set of powered PC speakers. The mixer (Behringer RX-1602) automatically mixes mono inputs as L+R and has a separate level adjustable stereo headphone output. Each input can be individually switched on/off. I did have to make a handful of isolation transformers to get rid of some ground loops but the mixer & powered speakers tolerate legal limit RF levels well. 73, Bill N2BC (checking every email now, waiting for my Katie-gram on a December K3 order!) ----- Original Message ----- From: "wayne burdick" <[hidden email]> To: "Bruce Osterberg" <[hidden email]> Cc: "Elecraft Reflector" <[hidden email]> Sent: Saturday, May 03, 2008 11:43 PM Subject: [Elecraft] Re: Perfect K3 Speaker > Hi Bruce, > > For communications bandwidths, a sturdy 4-ohm, 3 or 4" diameter mobile > speaker (non-powered) does a great job.

Bruce,
I am using and happy with a pair of Radio Shack Optimus XTS25 bookshelf speakers; I think this model is discontinued. I would think most bookshelf speakers would be good. My particular model is 8 ohms designed for 10 watts rms up to 20 watts max and I have room filling sound if I choose, it has a single 4-inch speaker and stands 6 1/2 inches tall. I normally run the AF gain at the 9 o-clock position. There are a lot of speakers out there that are specified for 100 watts or more. I haven't tried one but I would be worried about sufficient audio level being driven by the low wattage K3. Most PC speakers are low wattage. eham has a section reviewing speakers for communication use. http://www.eham.net/reviews/products/29 Mike Scott - AE6WA Tarzana, CA (DM04 / near LA) K3-100 #508/ KX1 #1311 ------------------------------------------------------------------- Date: Sat, 3 May 2008 21:05:52 -0500 From: "Bruce Osterberg" <[hidden email]> Subject: [Elecraft] Perfect K3 Speaker To: "Elecraft Reflector" <[hidden email]> Message-ID: <[hidden email]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Good Evening: If I was to add an external speaker to the K3 what would it be, looking for suggestions as Dayton is just around the corner. 73 Bruce N9BX K3 # 775 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Bruce:
I'd suggest a 4 Ohm speaker! Actually, I'm using two (2) of the old Motorola UN-amplified mobile speakers available on EBay for $10 or so. They are either 3.2 or 4 Ohms and work GREAT! 73, Tom N0SS At 21:05 05/03/2008, you wrote: >Good Evening: > >If I was to add an external speaker to the K3 what would it be, >looking for suggestions as Dayton is just around the corner. > >73 Bruce N9BX > >K3 # 775 > >_______________________________________ >No viruses found in this outgoing message >Scanned by iolo AntiVirus 1.5.3.5 >http://www.iolo.com > >_______________________________________________ >Elecraft mailing list >Post to: [hidden email] >You must be a subscriber to post to the list. >Subscriber Info (Addr.

My pick is the RadioShack Optimus 8 or 11. I believe these are long out of
production but widely available used on the Internet. I also second N4LQ's recommendation on the MFJ ClearTone for CW. I think the audio "fullness" of the existing K3 speaker could be substantially improved with the simple addition of a baffle. A few weeks ago, I looked at this and there appears to be just enough room to form a sealed square box around the speaker to form an "infinite baffle." The problem with 99% of the existing communications speakers is that the path from the back-wave of the speaker is far too short and results in low-frequency cancellation. The baffle prevents back-wave and forward-wave cancellation. The result is substantially improved low-end content below 400 Hz.

My 2 cents.... I took Tom's (N0SS) suggestion and found two 4 Ohm com speakers. They are not Motorola....but are Midland speakers boxes. They were marvelously. I tried the Radio Shack OPTIMUS but they sounded muddy. They sound good on the two meter FM rig in the shack, but not HF. I tried some nice computer speakers (two sets) and they sounded "tinny." The 4 Ohm Midland speakers, and I have two so I can use AFX, just sound marvelous. I really am surprised. And...they were FREE! A local ham had them in his junk box and gave them to me. FREE! Love FREE! 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 don't know if it's perect, but I like it. If you can get over the fact that it's a
mobile CB (gasp) speaker, you find that it is built like tank and has a reasonable communications type sound. A nice change from the plastic and thin sheet metal cabinets. The cable has decent size conductors too. The model is an SRA-168 from Ranger Communications: www.rangerusa.com I added an on-off switch to the back, because I have headphones and a speaker always plugged in. I even made an "Elecraft" namepalte to cover up the "Texas Ranger" logo on the front. hi hi Neal WA6OCP K3 #305 on the

Hi Bill, Due to space limitations, I have a random wire antenna only 10' from the shack that I use on some band. Its RFI gets into powered computer speakers. So I turn them off when it's an issue, and use only unpowered speakers with the K3. The K3 can easily drive two good-size bookshelf speakers. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I am awaiting my K3 to be ready including all the options I ordered (DVR etc.). I am planning on connecting two small bookshelf speakers (Proson Sat 51RR) who have excellent audio. I am currently using these on my IC-756pro3, and they sound a lot better than any amateur radio speaker. If one really wants to reveal the details in the received audio I can recommend the AKG HSD-271 headset (with dynamic microphone). These are outstanding in every way, and sounds incredibly clear and neutral. The electret mic version of these are the HSC-271. Best regards LA4AMA Roar |
