Line Out Jack
Locked
 
|
Hi,
This is Mark Griffin, KB3Z. Does anyone know the size phono plug that I would need for the Line Out Jack in the back of the K3? I think it is 1/8" but I am not sure. Thanks for your help!

I think mine are 3.5 mm, I don't have a metric stick handy right now,
they work fine. If it becomes a big issue, I'll get the micrometer out tomorrow. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 4/7/2014 5:47 PM, [hidden email] wrote: > Hi, This is Mark Griffin, KB3Z.

There was a long thread on this recently. Essentially modern 3.5 mm plugs and 1/8 inch plugs are the same thing. Neither are exactly the dimensions given but both will work in the intended jack.
The K3 manual (p 8) lists 1/8 inch for the rear jacks. Note: All plugs should be stereo type. 73, Brian, K0DTJ ______________________________________________________________ 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 Message delivered to [hidden email] |

3.5mm and 1/8 inch are now the same thing - one place calls them 3.5mm
while others use the 1/8 inch designation for the same thing. Yes, it was not always so, but that was well before stereo plugs and jacks came into existence. The big issue now is manufacturing tolerances that might mean some jack and plug combinations are tight while other combinations may appear to be sloppy. 1/4 inch plugs and jacks are more tolerant of sloppy tolerances i.e +/- 0.01 mm compared to 3.5mm is much greater than +/- 0.01 mm compared to 7 mm (or is it 8mm?). 73, Don W3FPR On 4/7/2014 9:32 PM, Fred Jensen wrote: > I think mine are 3.5 mm, I don't have a metric stick handy right now, > they work fine.

I'm curious about this. If anyone has reference to an actual 1/8"
connector, please forward off list. I don't recall them ever being anything but 3.5mm. My recollection is that 3.5mm and 1/8" have always been used interchangeably. I believe (guess) the discrepancy is simply that the plug originated as 3.5mm and 1/8" is the closest fractional inch (9/64 is unsatisfying). Checking specifications from one reputable manufacturer calls out sleeve diameter of 3.5+/-0.05mm for the plug and 3.6mm for the entrance of the jack. As with so many things, I'm sure there's no difficulty finding poorly designed/manufactured Asian parts that deviate. There's no such issue with 1/4" phone connectors. They are called out either as 6.35mm or 6.3mm, which is quite accurate because they originated as the fractional inch dimension. 73, Josh W6XU On 4/7/2014 7:11 PM, Don Wilhelm wrote: > 3.5mm and 1/8 inch are now the same thing - one place calls them 3.5mm > while others use the 1/8 inch designation for the same thing. > > Yes, it was not always so, but that was well before stereo plugs and > jacks came into existence. > The big issue now is manufacturing tolerances that might mean some > jack and plug combinations are tight while other combinations may > appear to be sloppy. > > 1/4 inch plugs and jacks are more tolerant of sloppy tolerances i.e > +/- 0.01 mm compared to 3.5mm is much greater than +/- 0.01 mm > compared to 7 mm (or is it 8mm?). ______________________________________________________________ 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 Message delivered to [hidden email] |

Just to be awkward, my mono and stereo versions all measure 3.48 to 3.49 on
the barrel but 2.94 to 3.02 on the tip. Nothing measures 3.18mm ie 1/8inch. It's been said before: 1/8inch is an approximation.

The drawing I referenced with the sleeve at 3.5mm shows the widest part
of the tip at 3.0mm. On 4/8/2014 11:10 AM, David Cutter wrote: > Just to be awkward, my mono and stereo versions all measure 3.48 to > 3.49 on the barrel but 2.94 to 3.02 on the tip.

It's been said before: 1/8inch is an approximation. These, and most other common connectors, are defined by IEC Standards, which include drawings of the connectors. First quality manufacturers follow those standards. "No name vendors may not. 3.5mm and 1/8-in should be viewed as "names" for them, not precise dimensions. The only high quality manufacturers I know of for these (and for most audio connectors) are Switchcraft and Neutrik. W6XU is in manufacturing, and may know of other good sources. 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 Message delivered to [hidden email] |

As is "3.5 mm" as well. Inching our way to metric over here in the new
world. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 4/8/2014 11:10 AM, David Cutter wrote: > Just to be awkward, my mono and stereo versions all measure 3.48 to 3.49 > on the barrel but 2.94 to 3.02 on the tip.

All,
I was involved on this thread very early in its life because I had remembered having a transistor radio that had a mono earphone jack which wouldn't accept a modern 3.5mm plug. At the time, I thought it was a 1/8 in. jack. The radio was from Japan and it was made around 1959. I suggested that I might be able to find one in my junk box. Well, I went through my entire junk box, as well as a box containing earphones dating back to the 1930's, and found one plug (mono) that had a 2.5mm mono plug on it. Everything else was 3.5mm. Based on all of my searching, I believe that the old transistor radio actually had a 2.5mm jack, and not a .125 inch jack as I thought. I am also concluding that 3.5mm and 1/8in. plugs are the same thing since I have found no evidence that a .125 inch diameter plug has ever existed. If anyone finds one, please let us know!
