I am thinking of doing it. I hadn't seen the comment in the code. I just thought I'd ask if there was some compelling reason not to try. Why spend a lot of time on something that you had already figured out wouldn't work.
I've replaced the initial DFT on the receive signal from the original complex to complex one with the real to complex one in FFTW3. That one doesn't generate the bins above half way (Nyquist frequency) so I've had to adjust the code. I've already fixed the agc calculation and the spectrum / waterfall display to use only the lower bins, but I still had to write code to invert the sideband.
