I'd just use a DIN to DIN with the appropriate leads crossed over.<br>
<br>
The source impedance of a typical TNC is reasonably low for tx audio
and, rx impedance is typically >10k. Audio levels would be
'about' matched. Typical demodulators can handle a reasonably wide
range of input levels starting at a couple of hundred mV <br>
<br>
I've used that technique with 9k6 modems (YAM and Baycom USCC)<br>
