Good point; one can go search through this list's archive & find many places
where someone writes asking how to do some specific task, e.g., CR or DSA -- as
if expecting that GNU Radio already has a solution that they can leverage.
Clearly there is a perception out there that GNU Radio -is- a generic solution,
and then they don't bother to RTFM to figure out that it's more like Octave &
that they have to create their application themselves. Better documentation
would help, but it will never solve this issue.

I often use GRC for simple tasks -- it's a LOT faster than writing Python
scripts, and it "just works" for these tasks. Admittedly, these are simple --
such as reading a file of audio data, adding in gain, and then both displaying
a waterfall FFT and piping the data to audio out. I do agree that for any
cutting-edge project what you write is true, but if GNU Radio accumulates
blocks over time GRC will eventually fit the needs of that 90+% I keep talking
about. Of course, that ~10% will always remain, as they are the cutting edge
folks.

True, but it's an enormous class. Maybe I'm too limited, but I cannot think of
a communication algorithm that can't be implemented graphically in GRC, somehow
(or the equivalent, via some combination of a data-flow graph and text command
line such as provided by Python).

True, but that's OS-dependent and a nuisance. Why not the dual-license
approach -- one as GPL and another that allows for local IP (the LGPL would
probably suffice)? Again I don't know if the FSF would allow it, but there are
plenty of potential end-users who would benefit from this model. - MLD
