Re: [Elecraft] K2 speaker jack question
I think I'm going to install a speaker/headphone switch on the back panel so I can just leave the headphones plugged in all the time. Then switch headphones speaker as needed. Apart from the mini-plug being relatively fragile, it's also annoying to plug unplug. It doesn't go very easily and I often hit the menu button while trying to work it. I have to say, it's the only really annoying feature I've found on the K2. 73, Drew AF2Z On Fri, 01 Jun 2007 21:37:02 -0400 (EDT), Al WA6VNN wrote: I just replaced the connector on my K2 #4887 because the internal bypass switch that is supposed to connect the speakers when the headphones are unplugged wasn't making contact.

[Elecraft] K2 speaker jack question
OK, a possible dumb question. K2 finished and working FB ! Audio from the headphones is fine, but no audio from the internal speaker, or from the external speaker jack on the back. Receive current is 220mA, so no apparent ground short, as warned against in the manual. All the connections look good. Has anyone encountered this before? Could I have gotten an external speaker jack that is supposed to be wired as in the manual rev. F, rather than in the errata rev F-12 (which is the exact opposite of the original manual)? Thanks for any help or suggestions. 73 Eric N0HHS K2 #6106 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K2 speaker jack question
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 Eric Ward wrote: OK, a possible dumb question.
