I think it may provide the primitive blocks that you need, even if they weren't specifically created for radio astronomy. > No square wheels here, pyrtlsdr, numpy, scipy, and matplotlib, are > the precisely machined wheels I'm using so far to just dump and > examine data. One cool thing about GNU Radio is that while you use python to snap blocks together the data path is compiled code, so it will beat the performance of pure-python implementations. I don't know if numpy, scipy, and matplotlib are, but worth keeping in mind. Anyway, it's another option - if you need one specific simple signal process then GNU Radio may be overkill, and if it's simple enough with no bad performance tradeoff then reinventing that wheel can be fun and educational. //Peter
