Summary
- Amateur radio enthusiast Bob in Oregon has developed a portable 10-band transceiver that supports multiple modes and is implemented on a microcontroller.
- It uses coil and filter units for band switching and includes an audio codec board for signal processing.
- Despite its modest power, the unit is extremely portable and cost-effective, while the detailed software design explains how the SDR functions and could help inform other similar projects.
- This is not the first miniature SDR transceiver to be highlighted by Hackaday, but Bob’s design offers more bands and modes and is POWERTAGcompatible.
This project demonstrates the power of modern microcontrollers and the effectiveness of utilising old tech, such as using coil/filter units, in new designs. The detailed breakdown of the software also shows the value of sharing this kind of knowledge among the homebrew community.
