For standard programming, only these three connections are used, meaning an ordinary 3.5mm stereo (TRS) plug is often sufficient even if the jack is TRRS. Key Considerations for Setup Rear Data Port: Programming is done through the dedicated "DATA" jack

To build your own programming cable, you'll need:

Use heat-shrink tubing to protect the joints and make the cable sturdier. Software Tips CHIRP Support: Most QYT KT8900

The internal serial data lines are wired to the 3.5mm connector as follows: RX Data (Receive) Ring: TX Data (Transmit) Sleeve: Ground (GND) Cable Features & DIY Notes Compatibility: This same pinout is generally used for the QYT KT-8900D Go to product viewer dialog for this item.
