Joel, Certainly you can check the headphone jack with a continuity test. You should find continuity between the 'hot' side of P5 (pin 1 - closest to the side panel) and one end of R35 and R36 (the wrong end may show you about 82 ohms). If you find no continuity, then try resoldering the pins of the headphone jack making certain you heat the pins themselves (they do not stick above the board surface) - it is possible to have a cold solder joint because only the pad was heated because the iron was not on the pins.
Check the schematic for the RF Board sheet 1 in the lower left corner, the paths around the headphone jack should not be that difficult to decipher. 73, Don W3FPR > -----Original Message----- > > While I am writing this e-mail - does anyone have info > on in-circuit testing the suspect headphone jack of my > K2 with a multimeter before I go ahead and do the > desoldering job?
