Most of the "other" software definitely uses DttSP, either bare (on Linux or
OS X) or inside PowerSDR (Windows). It does the job pretty well, if I say so
myself, speaking as one of the authors, along with Bob McGwier, N4HY. But
messing around on the inside is not for the faint-hearted and the learning
curve is steep. The design is determined overwhelmingly by the need for
minimal latency in full-duplex, together with tight asynchronous control of
the lowest-level parameters. It isn't and wasn't ever meant for
experimentation. You need to have a pretty clear idea of where you're going
before you ever lift the hood to change something.

If what you want is to get your fingers into the software, assemble your own
soft radios, you definitely, positively, absolutely want to use GNU Radio as
the software backend. That's one of the things it's for and it does the job
wonderfully. Once you get the hang you can put together a new application in
minutes. I myself am right now in the process of developing some new
features for DttSP and am prototyping them all in GNU Radio first.

A decent soundcard is a must, though.
