Picking up this thread late, but have you run into this situation? From the Kit Assy Manual:
If you hear nothing in the speaker when first applying power to your K3S (and no headphones plugged in) hold CONFIG to access the configuration menu, then rotate VFO B to display SPKR+PH. Tap 1 on the numeric keypad until you see PH.R SW - and exit the menu. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of pastor...@verizon.net Sent: Tuesday, April 5, 2016 4:40 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Internal Speaker Update! Here is an update to the internal speaker issue with my K3. 1. If I plug my headphones into the speaker jack in the back I hear audio. 2. But, for #1 to happen the speaker setting in config must be #2. If it is #1, I get no audio. 3. I have even plugged in a new speaker I received from Elecraft yesterday and I still don't get audio from the internal speaker. 4. I am going to send this information to Howard at Elecraft Service to get his opinions on this. 5. Not sure whether the KIO3 board is defective or not. I have never moved or done anything with the board for it to become unseated.
