Mike, Before concluding that the headphone jack is at fault, check the wiring to the external speaker jack and the plug at the end of the wire. If the conductors are reversed at one of these points, the audio is shorted to ground.
The other thing you can do is put the plug into the RF Board connector and check for continuity between control board P3 pins 7, 8 and 10 through the headphone jack and on to the external speaker jack and the speaker. The ohmmeter will show you where the discontinuity is occurring. The headphone jack problem is rare - only a few occurrances have been reported on the reflector in the over 5 years that I have been participating, so put it down low on the list of possible 'things that could be wrong' until proven otherwise. 73, Don W3FPR > -----Original Message----- > > My K2 internal speaker is dead. > _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
