Simple Software Defined Radio based on Softrock Lite II. The IF generation and sampling is handled by an STM32F042. This design is intended to build a low cost NAVTEX receiver, but can be used for all kinds of purposes. The current design has an input bandpass filter ranging from 400 - 1600 KHz.
WARNING: So far I haven't been able to receive anything yet with this hardware. Please use at your own risk.
