[Elecraft] K3 Speaker Audio Quit

[James Bennett]

Well, this is a strange one. Last week my trusty old Yamaha CM500 cans finally got so deteriorated I got tired of picking small pieces of black rubber out of my ears so I looked for a replacement. Bought a Koss SB45 that I used for 15 minutes and quit because they hurt. Today I got a brand new CM500 delivered and hooked it up. 

What I got was nice audio in the headphones, but nothing to the speaker. I have SPEAKERS set to 2 for diversity RX. When I set SPKR + PH = yes I get audio to the headphones, but nothing to the internal speaker. When SPKR + PH is set to NO, I get nothing. Unplugging the CM500 cable makes no difference.

What the heck did I do to cause this? I hope it is something simple/stupid! Any ideas?
