Very hungry dog looking for squirrels

Please donate to help with the considerable costs: hardware, lots and lots of it, software, sadly not free (Windows, Visual Studio, Intel IPP, CodeJock, ...).

And then there's the dog food! So if you like the SDR software I write please consider a donation, at least to stop my dog from getting too hungry.
