DUV using the Kenwood TS-2000x
Love my new radio, BUT it seems the audio output on the ACC2 connector pin 3 (MANO) has some filtering on it. It's also only present when the squelch is open. On my V71A, there's a signal called "PR9 Output 9600 (bps) repeat signal" which is always present regardless of squelch etc., and works very well for tapping the audio for DUV detection.
I did discover that I could get a EYE diagram (kinda) after turning the 'Lo/Width' knob all the way down. So I believe that means that the radio is filtering the MANO output which it shouldn't....
Has anyone modified the TS-2000 to tap into the audio before it is filtered? I hear this was a practice for a long time. Just assumed Kenwood would have provided a better output for work like this.
Then again I easily could be overlooking something simple... if so, please tell me! Attached is the EYE diagram.
Thanks,

Hi Lisa, use the 9600 packet pin. It works without modification to the rig. Not able to look up which pin or connector but it’s there. Put the rig into 9600 packet mode via menu and use FM. Mark N8MH.

Try setting menu option 50F to 9600.
