My SDR – Ethernet link part

I finally started my big SDR project, and this week-end, a major piece has fallen. I wrote the microcode for the PIC32 microcontroller and debugged the communication between the PC software (a plugin for HDSDR) and the device. This part can be resumed to a sound card over Ethernet. Most of SDR hardware required to be close to the computer (ex. USB connection or audio connection to the sound card) and my wish is to build a full SDR system that could be operated remotely and placed close to the antenna. Above all, this is important for the hyperfrequency because the loss in the coaxial cable are important at these frequencies.

The next step is now to design and build the PCB. This is not really a problem and this is the funny part for me. A few more efforts and I will be able to play with my full SDR system 🙂
