ZPTTLink is an open-source, cross-platform utility that connects Zello (running inside BlueStacks or Waydroid) to radio gateway hardware like the AIOC (All-In-One Cable). It enables seamless Push-to-Talk (PTT) control and audio routing between your computer and radio, creating a functional bridge between digital voice and RF communication.

This is a fork of F4HWN, which is a fork of Egzumer: https://github.com/egzumer/uv-k5-firmware-custom. Design to toggle flashlight on/off to give a decent sized pad to implement a COS line for gateways.

This tool allows Zello Free or Zello Work channels to be connected to USRP, enabling bridging of amateur radio networks to the Zello network.
