Hi Craig, hi Marcus,
Also, just because I need to point that out:
GNU Radio 3.7 is really a legacy series of releases by now. You should
avoid using it for new developments - it's getting harder and harder to
even build it on modern versions of Linux. In fact, a lot of its
dependencies simply

With an FFT size of 2**22 bins. This took about 20 seconds for the

Sharing your flow-graph. The exact error messages and more context would be good
Presumably you’re talking about FFT bins but it’s not clear.
Also why are your samples being conveyed as strings ? That’s wildly
inefficient.

I am working on a new application of gnuradio that pushes the
limits--satellite-based detection of RF from rotating
magnetized-quark-nugget dark matter transiting through the
magnetosphere--and need as many bins as possible to reduce the
background noise per frequency channel.
