Re: [Discuss-gnuradio] Visualising data with GNURadio

[CEL]

Hi Jaco,

this is really a reasonable thing to want, but to be honest, GNU
Radio's visualizations are very much oriented along the streaming
nature of GNU Radio – and scrollback doesn't fit all to well.

I recommend https://github.com/miek/inspectrum , which is relatively
new, and relatively cool :)

Other than that, there was a quite interesting email thread about this
in 2014 [1] with scores of ideas and tool recommendations!

Best regards,
Marcus
