If you want to build your own cable rather than purchasing a QYT USB cable , you will need a USB-to-TTL UART module.
The QYT KT-8900 is a popular mini dual-band mobile radio known for its compact size and affordability. However, many users struggle with programming it due to confusion regarding the programming jack's location and the specific pinout required for custom cables.
On most versions of the QYT KT-8900, the programming jack is a . Depending on your specific sub-model (KT-8900, KT-8900D, or KT-8900R), the location may vary:
: This radio is widely supported by CHIRP , an open-source programming tool. When using CHIRP, select QYT as the vendor and KT8900 (or the corresponding 'D' version) as the model.
: Use a module with an FTDI or CP2102 chip. Avoid older Prolific (PL2303) chips, as they often have driver issues on Windows 11. Solder the Connections :
: Ensure the radio is turned on and the correct COM port is selected in your software settings. Avoid using USB hubs.
: Ensure the 3.5mm plug is pushed all the way in. The recessed nature of the jack sometimes prevents standard bulky plugs from seating correctly.
Connect the pin of the module to the Tip (RX) of the plug.
