A hobbyist built a web-based remote control interface for the Albrecht AE-5900 CB radio by emulating its microphone serial protocol. The setup uses an FT232 USB-to-serial adapter, a USB sound card with isolation transformers, and a USB hub, all mounted on perfboard and connected to a Raspberry Pi. A Python script on the Pi serves a web frontend for full rig control with minimal hardware intrusion into the radio itself.
