First test was good. Second test no continuity or in the M-ohms... This is a newer K1 but it looks like the Jack is bad...

First make certain that the speaker cable is correctly inserted into P2 and that the crimp pins on the speaker cable are correctly inserted into the housing. Many builders have trouble with the crimp pins. When correctly inserted in the housing, you can look into the rectangular holes of the housing and see the locking projection on the crimp pins properly locked onto the rectangular opening. If your housing and crimp pins are OK, then remove the bottom cover and proceed as follows with your DMM 1 - Locate the switch on the back of your headphone jack - these are the 3 solder pads at the rear of the jack. Check for continuity between P2 pin 1 and one of the outer two pins of that switch (I forget which one it is, so check both - you should find continuity between P2 pin 1 and one of the outer ones, If that was successful -- (if not, there is a soldering problem between the headphone jack and P2). 2 - Leave one of your DMM Probes on P2 pin 1 and then (with the headphone plug removed), check for continuity from the center pin to P2 pin 1. If the first test showed continuity, but the 2nd did not, then you have a bad switch in the headphone jack. If this is an older K1, then I would suspect the headphine jack has failed, but if it is a new K1, I would first suspect the crimp pins on the speaker cable. 73, Don W3FPR On 10/5/2013 9:26 PM, Scotty Long wrote: > > Sent from my Verizon Wireless 4G LTE DROID > > -------- Original Message -------- > Subject: Re: [Elecraft] K1-4 s/n. 3206 > From: Scotty Long <[email protected]> > To: [email protected] > CC: > > Put all back together less the tuner now internal speaker is not working. > Headphone jack normal audio.
