Hi,
I didn't know about that particular pinout. I don't wish to redesign the circuit, but to be honest there's nothing against it. :-)
I updated the documentation:
73s!

The DB9 is for to interface the radio. I wanted to be manufacturer
agnostic, so you have to create a cable for your particular rig.
Does it follow any particular pinout (like the common KPC-3 pin assignments)?
Also, does it have Vin on one of the pins to power it and the Pi though that connector?
1-TXAudio (to radio), 2-CD, 3-PTT, 4-IO, 5-RXAudio (from radio), 6-Gnd, ...
Many trackers and other TNCs have followed this pinout.
