How to Download and Install Puxing PX-777 Programming Software
The Puxing PX-777 is a staple in the amateur radio community, known for its reliability and durability. While manual programming via the keypad is possible, using dedicated software is far more efficient for managing large frequency lists and advanced settings. 1. Where to Download the Software
Finding official software for older Puxing models can be tricky as the manufacturer's site often changes. The most reliable sources are community-maintained archives and radio enthusiast sites: Once the software is open and the radio is connected:
Puxing Official/Legacy Support: Historically, software was hosted on puxing.com, though it may require navigating through international versions of the site.
RadioReference or 409Shop: These hobbyist sites often host "PX-777 Programming Software" archives that are compatible with Windows XP through Windows 10.
CHIRP (Highly Recommended): Instead of the original factory software, most users prefer CHIRP, a free, open-source tool. It supports the PX-777 and is much more stable on modern operating systems like Windows 11, macOS, and Linux. 2. Necessary Hardware
You cannot program the radio with a standard USB cable. You will need:
A K1 Connector Cable: This is the standard "2-pin" Kenwood-style USB programming cable.
FTDI or Prolific Drivers: Many cheap cables use "counterfeit" Prolific chips that require specific older drivers to work on Windows 10/11. FTDI-based cables are generally "plug-and-play" and more reliable. 3. Installation Steps
Install the Cable Driver: Connect your USB cable without the radio attached first. Ensure your computer recognizes it in the Device Manager under "Ports (COM & LPT)."
Install the Software: Run the PX-777 setup file or open CHIRP.
Connect the Radio: Turn off the radio, plug in the 2-pin connector firmly, and then turn the radio back on.
Download from Radio: Before entering new data, always click "Download from Radio" (or "Read") to create a backup of your current settings.
Edit and Upload: Enter your frequencies, tones (CTCSS/DCS), and power levels, then click "Upload to Radio" (or "Write"). Troubleshooting Tips
"Could not open port": This usually means your COM port number is too high or the driver is not installed correctly. Check Device Manager and ensure the port is between COM1 and COM4 if using older Puxing software.
Check the Connection: The 2-pin plug must be pushed in completely. Sometimes the plastic casing of the cable hits the radio body, preventing a solid data connection.
