You can use K5 Viewer on your PC either as a Python script, or as a web application directly in Chrome-based browser (like Chrome, Edge, Opera, etc.).

Here is a quick tutorial for dummies:

1️⃣ Flash your Quansheng K5 with F4HWN firmware v4.3 (Bandscope, Broadcast, or RescueOps edition only)
2️⃣ Keep the K5 connected to your PC via the USB cable
3️⃣ Go to https://armel.github.io/k5viewer/
4️⃣ Click Connect (and select the serial port)

That’s it. Nothing to install. Nothing to configure. Just plug and view 🤭
