I created a noise source and a tcp sink (server). I connect to it with SDR# (on another machine) and get plenty of noise. Next I created a signal source of 1khz and add that to my noise source. The unexpected result: carriers all over the spectrum. None of which are at 1khz.
You're probably having a good laugh. You're welcome.
I'd like to modulate the amplitude of a carrier and drop that into a randomly-generated noise floor. And I'd like to stream the whole thing to sdr-software across the network. Are my expectations too wild? Is this possible?
