[Elecraft] Internal keyer

[Earl Ritchie]

I have connected my bencher paddles using the stereo plug and the menu set to PDLn. I have checked U6 on the control board and pins 29 & 30 show the correct resistance and voltage.   My problem is that when either paddle is pressed, I get only a steady tone--no dits or dahs.  Speed setting doesn't change anything, just a steady tone.  Has anyone else had this experience and/ can offer some help?
Tnx, Earl
