[Elecraft] 1/4" paddle jack rear panel of K3

[Linda and Bob]

Rick,
I just checked the rear panel at the paddle jack area. There is no external lock washer or nut on this outside threaded jack. It may be possible to place a round or hexagonal nut on the outside of the jack on the rear panel. This may help to tighten the jack from the outside of the radio cabinet . I believe that there isn't an internal nut holding this jack. It must be soldered to one of the internal PCB's.

If I knew the tread diameter of the paddle jack, I might be able to install a round nut over the threaded shaft of the paddle jack (on the outside). Maybe Elecraft could send me this part. The 1/4" key jack next to the paddle jack is tight with no wiggle. It must also be located on the same PCB.

I have to check the assembly manual for this illustration. I only have the operating manual. My K3 was factory built. The paddle jack has been loose since I purchased my K3/100.

Perhaps, Don, W3FPR knows what to do? I will also contact Elecraft service as well as Eric.

Only the rear portion of the bottom cover needs to be removed (figure 2; page 8 of the K3 manual). It looks like there are 7 screrws which are 3/16" long with no lock washers as well as 3 screws with tooth lock wahsers 1/4" long [10 screws in total]?

  You could open the rear lower panel and check the soldering on its pins. Then contact support at elecraft.com.

    Rick,
    Thanks for you reply. I will check to see if the nut surrounding the jack is tight. My K3/100 was factory built, but you never know if the builder was rushed, hi! Perhaps it became loose in transit. 

    If it is tight and still wiggles, what do you suggest?

      It shouldn't wiggle at all. CHeck the nut around its shaft that holds it to the rear panel.

        The 1/4" paddle jack on the rear of my K3/100 wiggles much more than other
        rear panel jacks. Is this normal? I am afraid that the paddle jack may
        disconnect from the PCB that it is attached to inside the rig.

        BTW, the 1/4" key jack next to the paddle jack does not wiggle at all.

        It only seems to be a problem when I remove the paddle cable and plug from
        the jack (which is rarely done) and then plug it in again. Thanks for your
        help and input.
