Ok...Let me ask YOU. Do you own a K3 and have you done this?

I kind of hope that Eric comes in and kills this thread.
I have NEVER had the power poles “fall out” of the back of my K3. That said, I don’t pick up my radio and try to throw it across the room, I don’t have my cables arranged where I can easily get them tangled in my feet and pull them loose, and I don’t rearrange my desk (apparently nearly as frequently as most) by sliding the radio to and fro daily. It is true that if I were to pull the radio off of the front of the desk, the power poles would pull out. It is also true that if I threw a brick at a window, it would likely break … Grant NQ5T On Mar 13, 2014, at 1:29 PM, Roger D Johnson <[hidden email]> wrote: > Ok...Let me ask YOU.

Hi,
I kind of hope he will not kill this thread. I really have no problem with APP. I assemble my own, I solder them, I know how to click them together and I have no problem with them separating from their mate or falling apart. By far the worst connector to pull out or make connection problems on the back of the K3 is the awful 3.5mm phone connectors. I do not know why they are in such widespread use other than the fact that headset manufacturers put them on their sets. If I pull my K3 forward on my desk (which I try to avoid) these connectors are the only ones to come undone, *never* the APP power connector. If I were to rate the connectors on the rear of the K3, this would be how I would do it: 1. BNC - the most perfect connector in the world. 2. UHF - properly tightened, it's perfect. 3. RCA phono - with a good quality male, it's problem free. 4. APP - properly assembled, it has sufficient separating force. 5. Did I miss something here? 6. 3.5mm phone (mono and stereo) - never come across a pair that is not intermittent when wiggled. Junk! AB2TC - Knut

Re: Powerpole police here....

OK...this is getting out of hand. I would suggest Elecraft make the cutout in the
back panel of the K3 a bit taller over the chassis mount PP connectors. This would allow the use of the retaining clip and prevent this problem. I would have done this long ago but I didn't want to hack up the back of my K3. 73, Roger ______________________________________________________________ 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 |

3.5mm & 1/8" are not quite the same size, so if you've put a 1/8" plug in a 3.5 mm socket, you might find this problem.

You're a radio amateur, Charlie, so you really should be able to figure
this out yourself. There more than a 10% difference between .125 and .137795. Is that quite a difference? That's more than the difference between a .38 cal. bullet and a .40 cal. bullet. Are those interchangeable? 73, Scott, N9AA On 3/15/14 6:36 PM, Charlie T, K3ICH wrote: > That doesn't answer my question.....

There really are 2 different standards, ie there are 2 different parts that
are manufactured and it's a pain. If a plug is hard to push in, then it's probably not meant for that socket, even if it looks like it should be.

Re: Powerpole police here....

OK, THAT's exactly the answer to my question. There really ARE two
different standard sizes. I guess the only way to know which ones you have in your hands is to measure them. I don't think I could tell the difference by eye. Maybe if I knew I had one of each in my hands it might be possible to see the difference.

Charlie, I don't have a set of calipers or mikes handy but grabbing a steel rule and measuring three 3.5mm plugs at random off my bench - they all look to be 9/64 (0.14"). I do know that I've thrown out all of the 1/8" plugs I had because they make such bad contact in equipment. I don't know of any amateur manufacturer that is still using 1/8" jacks. They can be damaged if one forces a 3.5mm plug into them. 73, ... Joe, W4TV On 3/15/2014 6:36 PM, Charlie T, K3ICH wrote: > That doesn't answer my question.....

I do have calipers, and I just measured 8 of the plugs I have in stock.
They were ordered both as 1/8 inch and 3.5mm plugs, and they all measure 0.135 inches. Unless you have very old true 1/8 inch plugs (likely mono), I don't believe you have any fit problems. The current "1/8 inch" and "3.5mm" plugs are identical. Those are 'nominal' dimensions. 73, Don W3FPR On 3/15/2014 7:28 PM, Joe Subich, W4TV wrote: > > Charlie, > > I don't have a set of calipers or mikes handy but grabbing a steel > rule and measuring three 3.5mm plugs at random off my bench - they > all look to be 9/64 (0.14").

The two dimensions are descriptive, and which is used depends on the commonly used measurement system in the countries involved. The dimensions of these connectors are defined by IEC standard. That said, a disgustingly large percentage of connectors sold in the marketplace are quite careless about that standard, so it's easy to get out of tolerance junk. 73, Jim 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 |

Re: "Are they REALLY 0.137795 inches or is 3.5mm just a rounded off way to describe the same physical part using two
different measurement standards?" Charlie, Not sure you are going to get a real definitive answer, but I now believe the 1/8" designation is just a rounded off way to describe a 3.5mm connector. I didn't believe that before this thread got going. I dug out all the old connectors I could find from the very bottom of my junk box and measured them. All of them measured 3.5mm (0.138") as best I could read on my calipers. None were below 0.137. I thought for sure I would find some that were 1/8" (0.125") dia., because I remember buying some of them from the local "exploded television" store that were marked as 1/8" phone plugs. I think those were all mono, not stereo. In those days, I didn't have a set of calipers or a micrometer to check them, so I just assumed they were 0.125" dia. Looks like that assumption was wrong. Whoever wrote the Wikipedia entry on "3.5mm Plug" agrees that 1/8" is just an approximate description used in some countries, and that they actually measure 3.5mm (0.138") diameter, which agrees with my junk box. I also did a search of Mouser looking for 1/8" Plugs, and all I came up with was 3.5mm plugs. My memory still recalls seeing connectors that wouldn't quite fit together correctly, but I don't have any that I can find now...and I have some pretty old junk. Just ask my wife! ;-) 73 Mark KE6BB From: Charlie T, K3ICH<[hidden email]> Sent: Sat, Mar 15, 2014 at 09:35 PM To: <[hidden email]> Subject: Re: [Elecraft] Powerpole police here....

Some of the old one eighth inch plugs out of the 60s will not make contact in the newer jacks. These are the two conductor type. So I think that years ago a 1/8 plug was really a 1/8 plug.

I just measured a bunch of them (all 2 cond) with my handy-dandy Harbor
Freight digital micrometer and they range anywhere from 3.3 mm to 3.6 mm, so the comment about a lack of manufacturing standards is obviously appropriate. 73, Charlie k3ICH ----- Original Message ----- From: "Gerry leary" <[hidden email]> To: "Mark Petiford" <[hidden email]> Cc: <[hidden email]> Sent: Monday, March 17, 2014 7:22 AM Subject: Re: [Elecraft] Powerpole police here.... > Some of the old one eighth inch plugs out of the 60s will not make contact > in the newer jacks.

That is my recollection as well. The standard was 1/8" for a long time, originally as a mono connector, until many personal electronics products manufactured outside of the USA started showing up with 3.5mm plugs & jacks. Had they wanted to adopt the existing standard but use metric naming, it could have been called 3 mm (.118"). I just mic'd a plug on a B&O (Danish company) earphone set at .1377" (3.5 mm x .03934 = .13769").
