Mike, If the K3 is not going into transmit, do you have the VOX set on for AFSK-A mode? If you chose not to do that, you will have to use the "one transistor circuit" from a serial port to activate the K3 PTT.
There are audio level controls in the computer too - right click on the speaker icon (assuming it is displayed) to open them, otherwise go to the Control Panel to adjust them. Set the Line-out level to about 2/3 of full slider. Be sure the Line Out is not muted. Yes, the Mic Sel setting of Line-in is what I was referring to.
