Once you’ve filled out your channel list, click the "Write" button. The radio’s screen will usually flash "Program" or "Writing." Once finished, the radio will reboot, and your new channels will be ready for use. Common Troubleshooting Tips

Programming Software Overview

1. Official Programming Software

The Zastone D9000 uses CHIRP (officially supported) or the factory Zastone D9000 CPS.

• The cable uses a genuine Prolific PL2303 or Silicon Labs CP210x chip. (Avoid counterfeit Prolific chips, as modern Windows drivers will reject them.)
• After connecting, install the correct driver. The software typically communicates via a virtual COM port (e.g., COM3).

To program the D9000 via a computer, you need two specific items:

• Channel No: The memory slot (1-xxx).
• Rx Freq: Receive Frequency (e.g., 146.520).
• Tx Freq: Transmit Frequency. If using a repeater, you can set this manually or use the Offset function.
• CTCSS/DCS: Tone squelch settings (often called Privacy Codes).
• Power: High (H) or Low (L).
• Bandwidth: Wide (W) or Narrow (N).

: Some users found it impossible to program specific bands (like airband frequencies) through the software even when they were accessible directly on the radio. Compatibility Issues
