Aaron,
Unless you have done some sort of mod to that K2, you do NOT have
speaker audio at pin 6 of the mic jack.
The audio is on the Control Board and RF Board, but NOT the Front Panel
board.
The schematic of the Kenwood MC-43S microphone from G4WPW (SK) shows no
speaker function and no connection to pin 6.

I have been using a Signalink USB with my K2 and the last time I
hooked the SignaLink to the K2 there was a real bad feedback sound
every time the rig went into transmit. It received just fine. So I
contacted Tigertronics and started a dialog with them and it turns out
I could have been setting up the Signalink wrong. Here is the setup, I
have my K2 wired to use a Kenwood MC-43S microphone. When I bought the
Signalink for the K2 they sent me the microphone cable and an Audio
cable. As per the instructions that I received from Tigertronics I am
to use the 8 pin microphone cable to connect from the K2 to the
Signalink. Then I have to connect the audio cable from the Ext Speaker
jack on the back of the K2 to the SPKR jack on the back of the
SignaLink. Then the USB from the SignaLink to the computer. Now
Tigertronics are saying that I do not need the audio cable. In the
dialog they asked what microphone I am using what it the pinout for
that microphone:
Pin1 Mic Input
Pin 2 PTT
Pin 3 N/C
Pin 4 N/C
Pin 5 8 VDC **
Pin 6 Speaker **
Pin 7 Mic GND
Pin 8 GND
** Speaker audio and power are available on some models.
Tigertronics is now asking for certain if I have Audio on Pin 6. Is
there a way for me to check this without having to take the K2 apart?
