Software Defined Radio (SDR)
Software Defined Radio (SDR)
Has anyone considered trying to make a SDR with Flowstone?
Beside the necessary broadband radio receiver hardware (readily available), seems like all that would be needed would be a spectrum display or waterfall display with persistent scrolling, necessary filters (lowpass, highpass, bandpass), a way to select part of the spectrum maybe similar to the SynthMaker frequency splitter module, and a way to play the resulting waveform using a wave player module. Iam probably over simplying it and some parts (algorithms) might have to be coded.
I have reviewed the internet literature and you can find many SDRs already, most programmmed in C++ or even java (on-line versions). There is one good article on programming a simple version of SDR in Max/MSP.
Seems like a simple broadband radio receiver could be developed (like the Flowstone board) and sold as a kit along with the software similar to Funcube.
...just an idea.

Re: Software Defined Radio (SDR)
Not exactly what you are suggesting but we did make an FM radio simulation example a while back:
