\textbf{PCBWay} sponsored part of the prototype PCB fabrication and assembly
costs for DigiRadio. Their contribution did not cover the full production
budget, but it materially reduced the out-of-pocket expense of the first
manufacturing run. We thank the PCBWay team for believing in this open hardware
project and for helping bring the first boards to life.\par}
