[Elecraft] K2 speaker jack question

[Don Wilhelm]

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 Control Board, and of course, no speaker audio is 
available there.

Are the crimp pins inserted properly into the housing?  They must be 
inserted until the locking tabs secure the crimp pins - the top of the 
crimp pins will be below the top of the housing and should stay in place 
when the housing is mated with P5.

If you are still concerned about the jack wiring, you can check it for 
continuity with an ohmmeter.  The hot side of the speaker connector 
housing should have continuity with the speaker + terminal, but if you 
plug a phone plug into the jack, the speaker should not show continuity, 
but you should have continuity to the tip of the inserted plug.

73,
Don W3FPR
