XTL/XTS5000 XTL Dashmount PC Audio

[KG5HHS]

Hello All,
I am planning to use an XTL5000 dash mount with W7 control to feed audio to a PC's Mic/Line in port for streaming. I have read some contradicting information about what pins to use from the 26pin connector on the rear. I will not need local microphone audio as this radio will be used just to receive. I would like to wire it for a 3.5mm female mono jack. From the pinout diagram it shows that pin 21 is for receive filtered audio out. Where I have run into some confusion is some are saying to ground to Pin 1 or Pin 14, while others are saying not to ground at all. Any information would be greatly appreciated.

I add audio to many of my plugs for station speakers. I use Pin 14 for ground (which is jumper to pin 15. Just strip back wire, solder new wire heat shrink. Mine go to a RCA connector.

Pin 21 (RX_FLT_AUDIO) of the Auxiliary connector working against ground is correct. The audio output level will be too high for direct microphone connections in most cases and will require a resistive divider (attenuation). Additionally, you may need to employ the use
of a 1:1 audio transformer to prevent a ground loop when connecting your XTL to external devices.
