[Elecraft] K3 Speaker plug
Just want to be sure that I understand the External Speaker Jack stereo vs mono plug operation. To clarify, as long as you use the stereo plug, you can select CONFIG:SPKRS 2, regardless of whether or not the other end of the plug is stereo or using stereo speakers. It is just critical for the radio end to have the stereo plug. Do I have the correct? Just making sure I understand.

Re: [Elecraft] K3 Speaker plug
Bill, I do not understand the utility in connecting both the left and right speaker outputs to a single speaker - but I don't think it will do any harm. Connecting the audio amplifiers together is different than shorting the right channel to ground by inserting a mono plug. Why not connect to stereo speakers and enjoy the AFX or if you have the subRX, the combinations of main and SubRX receive in each ear (speaker). Spread the speakers out so the left speaker is in the left ear and the right speaker is in the right ear. If you put the speakers close together, you will not observe the effects. I do believe corrective actions have been taken for the audio amplifier shorted problem, but my memory is fuzzy about what and when. 73, Don W3FPR On 9/13/2012 3:04 PM, Bill Wiehe wrote: Just want to be sure that I understand the External Speaker Jack stereo vs mono plug operation.

Re: [Elecraft] [K3] Speaker Plug
Hmmm - interesting comments. I use a microHam DigiKeyer and the gold plugs on that fit very well - again a product from an European country using metric only.

The REAL manufacturers of audio products are members of international Standards bodies, like the Audio Engineering Society, and carefully adhere to those international standards. When you buy from companies like Amphenol, Switchcraft and Neutrik, you know what you are getting, whether it's called a 3.5mm plug or a 1/8-in plug.

Re: [Elecraft] [K3] Speaker Plug
I could infer from this discussion that 3.5 mm and 1/8 inch are two different types of connector but I find no evidence of that. The terms are used interchangeably by manufacturers. Switchcraft, for instance, titles their products as 3.5 mm but goes on to say all products are 1/8 inch. On their drawing you'll see the plug diameter given as 0.14 inch +/- 0.01. That's 3.56 mm +/- 0.25. They're also not cheap, but I recently bought some to try as I too have found this type of connector to be generally unreliable. The one that I went to the trouble of measuring showed poor sleeve contact. Maybe it's a corrosion problem. Lightly polishing the sleeve has helped with some of mine. Others remain incorrigible. I have not been able to find any industry standard for these connectors. 73, Carl WS7L K3 #486 __ 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] Speaker Plug
Generally, connectors described as 3.5 mm and 1/8 are fully compatible. Most manufacturers use the metric notation. 1/8 is more of a historical reference at this point, though we sometimes use either term in existing manuals. New manuals will all use 3.5 mm. If in doubt, use connectors described as 3.5 mm. 73, Wayne N6KR On Jan 3, 2012, at 10:07 AM, Carl Clawson wrote: I could infer from this discussion that 3.5 mm and 1/8 inch are two different types of connector but I find no evidence of that.

Re: [Elecraft] [K3] Speaker Plug
The only difference is in the diameter of the plug shaft, but the shape of the tip contact may have an influence as well. It looks like the industry tried to make a compromise plug to fit both 1/8 and 3.5mm jacks. After all, they are only about 0.01 different. However, that assumes that the contact springs in the 3/5 mm jacks have enough travel to reliably contact the slightly smaller 1/8 plugs. That appears to not always be the case. Of course, it has to do with the actual design of the leading end contact that is tapered for smooth insertion. Differences in that shape might be the cause for many intermittent fits. Too many variables, Hi! As I reported earlier, I have found the RS plugs marked 1/8 / 3.5 mm are actually closer to 3.5 mm and work FB. I bought a bunch a few years ago. Maybe the next time they will have switched vendors and they won't work. Who knows? As Jim, K9YC, reported, you can go to the major brands on line. He reports absolutely consistent results with them. Sometimes the higher priced spread is worth the money. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Carl Clawson Sent: Tuesday, January 03, 2012 10:07 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] [K3] Speaker Plug I could infer from this discussion that 3.5 mm and 1/8 inch are two different types of connector but I find no evidence of that.

Re: [Elecraft] [K3] Speaker Plug
Yes, I think you have missed the meaning of nominal Let me put it this way - the nominal 40 meter band can refer to any frequency between 7.000 and 7.200 MHz (we in the US will extend that to 7.300 MHz). Likewise, nominal 3.5mm can range from 0.125 to 0.140 inches, and a nominal 1/8 inch can refer to the same range. We do not live in an exact world, every physical thing has tolerances. Ask a machinist to build you something without tolerance specifications, and he will tell you that it cannot be done. How tight the tolerances can be held to is a sign of the quality of the product. Those parts with tighter tolerances cost more. That is why 1% resistors cost more than 5% resistors. 73, Don W3FPR On 1/2/2012 11:36 PM, Jim Wiley wrote: Hmmm - 3.5 mm = 0.1378 inches 1/8 inch = 0.125 inch Or am I missing something? - Jim, KL7CC Don Wilhelm wrote: Tom and all, You are ignoring one important word - Nominal A nominal 1/8 inch is equal to a nominal 3.5mm.

Re: [Elecraft] [K3] Speaker Plug
Having worked in manufacturing of the F111 FB when they did that I can imagine that to convert over would have cost BILLIONS. The United States manufacturers just decided not to spend the money to convert. Yes, the Metric system makes more sense, but a wholesale conversion would have been very expensive. Now would be a good time to do it since we don't manufacture anything in the USA any more, and when the Chinese collect our debt to them from us they will make it happen anyway. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member Only a white man would believe he could cut the top off of a blanket, sew it to the bottom and have a longer blanket. -- Old Indian comment about Daylight Saving Time On Mon, 2 Jan 2012 20:17:39 -0800, Ron D'Eau Claire r...@cobi.biz wrote: Part of the problem is that in the USA many suppliers consider 3.5 mm and 1/8 the same. For example I have a packet of Radio Shack plugs that is marked 1/8 (3.5 mm). I grabbed one and checked it, and it's 0.135 in diameter - 3.5 mm. No wonder it works FB in my K3. I'm inclined to go on another rant about how Americans refuse to accept metric measurements even though metric has been the standard system of weights and measurements in the USA since the 1960's, but I won't. Oh... I just did.
