Student Project Enables Hams to Experiment in the 33 cm Band

ARDC grant enables Bradley University students to develop an open-source, 915 MHz digital transceiver system.

Peoria, IL, June 18, 2022 --( DAEMod-915 is a Bradley University project whose goal is to design a digital transceiver system for experimentation in the under-utilized 33 cm band. The design includes support for multiple FSK/ASK modulation standards, and both hardware and software are open-source. The designers—Peter Handler, W9PLH; Connor Dickey, KD9LSV; and Philip Pierce, AC9YC—chose the 33 cm band for several reasons:

• It is one of the most under-utilized bands,
• It is available for use by non-licensed ISM users and licensed radio amateurs,
• It offers a good balance between cost, range, and available spectrum, and
• There is a lack of available open-source and open-hardware modules for implementing digital radio modes in this band.

Once complete, the DAEMod-915 project will reduce barriers to innovation in the 33 cm band. The project’s detailed documentation will allow radio amateurs to experiment with digital protocols without spending a lot of money, and allow developers—be they solo developers, other educational institutions, or amateur radio clubs—to build upon the base hardware and software for their own unique applications. Documentation for the DAEMod-915 project is at

About ARDC
Amateur Radio Digital Communications (ARDC) is a California-based foundation with roots in amateur radio and the technology of internet communication. The organization got its start by managing the AMPRnet address space, which is reserved for licensed amateur radio operators worldwide. Additionally, ARDC makes grants to projects and organizations that follow amateur radio’s practice and tradition of technical experimentation in both amateur radio and digital communication science. Such experimentation has led to advances that benefit the general public, including the mobile phone and wireless internet technology. ARDC envisions a world where all such technology is available through open source hardware and software, and where anyone has the ability to innovate upon it. To learn more about ARDC, please visit
