I doubt you will see anything useful if you open the rig. Multi contact jacks are usually closed assemblies not like the open contact types we used years ago.
There have been discussions of broken plug tips in Kenwood and Elecraft group. There seem to be two solutions. Either change the complete jack assembly or improvise a method to extract the tip the way it went in. I found one discussion here - https://www.mail-archive.com/elecraft@mailman.qth.net/msg246619.html Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
