Here is the exact pinout mapping from the radio's perspective: Plug Segment Connection Function Description RXD (Radio Receive) Receives data from the PC's TX pin. Ring 1 / Ring TXD (Radio Transmit) Sends data out to the PC's RX pin. Sleeve GND (Ground) Common ground reference line. Visual Alignment (From Tip to Base)

⚠️ Important: Unlike audio cables, these are wired for TTL serial (not stereo audio).

Inside the programming cable, the two plugs are wired to a (often a Prolific PL2303 or CH340 chip): qyt kt8900 programming cable pinout top

The QYT KT-8900 is a popular amateur radio transceiver, and programming it requires a compatible cable. Here's the pinout for the programming cable:

What (CHIRP, QYT factory software, etc.) are you running? What error message or behavior are you experiencing? Here is the exact pinout mapping from the

Alternatively, use a multimeter in continuity mode:

: Use an RJ-45 microphone pinout only if you are trying to interface with the mic port, which is generally not used for standard frequency programming. Software and Drivers Visual Alignment (From Tip to Base) ⚠️ Important:

While you can purchase pre-built commercial cables from platforms like Amazon or Radioddity , building your own custom DIY interface or troubleshooting an existing connection requires understanding the exact schematic layout. The hardware utilizes a standard located on the rear panel of the unit, which interfaces directly with Transistor-Transistor Logic (TTL) voltage levels. QYT KT-8900 Programming Pinout Breakdown

For the best results, use a CP2102-based USB-to-TTL adapter, keep your ground connection short and direct, and always test with CHIRP’s "Read from Radio" function before attempting a write. With the correct "top pinout" wiring, the QYT KT-8900 is a breeze to program, unlocking its full potential as an affordable, high-performance mini mobile rig.
