    For a long time I was looking for a cheap QRP transceiver that only communicates via USB. In my opinion, no one likes audio cables in their RIG. I finally found a Peaberry SDR V2 and soon found out I couldn't buy it anymore. Buying components and PCBs is not such a problem, but in the original design there are a lot of coils and transformers that need to be wound manually. I'm really lazy for that. That's why I combined the project with another amazing SDR.

    I have done the first tests and everything works very nicely. Only PA is missing on the PCB, but I think it is much easier to buy an external one according to each one preferences. This SDR perfectly fit for Raspberry Pi and it's cheap enough to have more than one in shack.

    So if anyone is interested, here are the sources:

    Does that mean one needs a pi to use it?

    Yes Raspberry Pi or any other computer...
