The easiest way to change the control is to cut the pins close to the

Rather then plug and unplug headphones, I simply wired up a box to take the
output from the K2 speaker jack, and feed it into a switch that in one
position drives the headphones and the other drives an external speaker.
This eliminates wear and tear on both the headphone cord and the headphone
Hi Don,
many thanks for dissasembling instruction sharing! It seems that it will
force me to replace the jack in my K2 and giving the radio back to my daddy.

Hi Tomy,
it sounds like the problem with headphones jack on front pannel.
The same happened over here with my K2. It is still sleeping on the shelf as
front panel removing is needed. ;(

When pulling out the head phones from the jack I do not have the K2 speaker
working. Just the head phones speakers.
I am using the Heil Proset head set.
Would that indicate a bad head phones jack?How hard is it to replace? 73! Tomy

Tomy,
Yes, that does indicate that the switch at the back of the headphone
jack has failed.
No it is not hard to replace *if* you know which screws to remove to
expose the jack.
If you do not have good desoldering equipment, crush the plastic part of
the jack with pliers or whatever tool
I just found my instruction for disassembling the K2 on the web at
http://www.qsl.net/wy3a/Replace_K2_Headphone_Jack.htm.
The instructions are specifically for the K2/100, but if you have the
K2/10, removing the top cover is similar to the instructions for
removing the KPA100.

I suggest you order several to have on hand. Their failure rate is high.

Recently after WFF activation, around 600 QSO’s with K2 I realized that when
I connect the headphones, speaker is not disconnected anymore, and I suspect

Curt,
The switch in the back part of the headphone jack (the switch that turns
the speaker on/off) has a plastic lever on it which does break on occasion.
Elecraft has tried unsuccessfully to have the manufacturer beef up that
lever, but unfortunately, it has been to no avail.
There is no
Thanks Don,
Is the part number you mentioned for the entire jack? I'm guessing the switch
is integral to the jack. And is there a way to confirm it is broken without
removing it. Looking at the headphone jack lands from the bottom of the rig
with the bottom cover removed, and the front of
Curt,
Yes, the 3 pins at the rear of the switch are the ones for the switch,
and it is integral to the jack housing.
I can't recall which two of the 3 pins close the speaker circuit, but
since your speaker does not work, check continuity - the two that show
continuity are NOT the ones for
Just bought a new K2 #4913. All is great, however, inserting a
headphone doesn't cut off the speaker. The headphone plug is a standard
3.5 mm plug. The schematics show the plug should cut the speaker.
Is there an internal parameter that needs setting? If not what's the
easy way to access
Chris,
In all probability, the little plastic lever which operates the switch
inside the headphone jack has broken. It usually fails with no speaker,
but it can fail either way.
It is a bit of a pain, but you can shut off the speaker by plugging an
empty jack into the external speaker jack
The K2 speaker has a small 2-pin header at the circuit board. No
need to unsolder anything.

I think I'm going to install a speaker/headphone switch on the back
panel so I can just leave the headphones plugged in all the time. Then
switch headphones speaker as needed.
Apart from the mini-plug being relatively fragile, it's also annoying
to plug unplug. It doesn't go very easily and I
OK, a possible dumb question. K2 finished and working FB ! Audio from the
headphones is fine, but no audio from the internal speaker, or from the

Receive current is 220mA, so no apparent ground short, as warned against in the
manual. All the connections
Eric,
I doubt if you got the wrong jack, but it is possible.
Check a few other things first - do you have the wires in the connector
housing correct, or are they reversed? Are you plugging the speaker
connector to P5 on the RF Board? A few builders have tried plugging it
into P5 on the

Hello,
In the CQWW cw contest I operated with K9VV as VP2VVV with K2/100 and

changed headsets and that did not mute the speaker. I vaguely remember
Tom,
Glad to hear the K2 is working good for you otherwise.
The normal problem is the other way around, the speaker does not come on
after removing the headset plug.
Although it could be that the headphone jack contact had failed to open, I
would consider that to be rare. You may want to check

I had the same problem. Go into the box and bend the speaker/headphone jack
down. It seems that when you put in the headphones, it bends the connector
up so that when you pull it out, it doesn't make contact to engage the
speaker. Good luck. Let me know if that fixes it.

James,
Before replacing, it may be that you only knocked it off center of the voice
coil.
Take out the speaker and view it from all angles. Is the Cone off center?
If the thing looks like it is, you might put three fingers and thumb equally
around edge of voice coil at narrow end of cone, and
A repair for the Elecraft K2 speaker with a rubbing voice coil that worked
for me is as follows:
Remove the K2 lid and lay it on the bench next to the rig with the speaker
connected so you can access the back of the speaker while listening.
Enable the sidetone so you hear it in the speaker
Well I did it. By accident at field day I overloaded the K2's speaker
with too strong a signal and with the volume accidentally turned up

Has anyone had a problem with their K2 speaker? Mine sounds like something is
loose whenever I listen to cw at around 60% volume, like something vibrating. I

John,
It is very likely a wire stuck (magnetically) to the speaker and touching
the speaker cone. It could be on the outside of the speaker (if you are
fortunate) or it could be on the inside and you will have to remove the
speaker to see it.

Sometimes the speaker frame gets warped after shipping or some other
