Isn't it boring to do "real-time signal processing" without hardware?

For offline simulation there are tools like GNU Octave, Scilab or Matlab
with more communications, modulation, signal analysis and graphical 
These are more than sufficient for simulations and theoretical studies.
I know, Gnuradio is also a nice signal processing software by itself,
but the real advantage of Gnuradio is the real-time processing
with hardware sources and sinks. For offline analysis, there are toolboxes
for TF spectral analysis etc.:
or signal processing:
In Gnuradio I'm missing all these analytical capabilities.
Just for generating modulated signals you don't need Gnuradio.
Gnuradio is relevant when you're operating on continuous streams.

I'm not against pure software development.
But please respect the opinion that people also want hardware for
real-time signal processing. Somebody who asks for hardware is not
interested in answers that software is much more beautiful.

The hardware question is very important for people that are not
financially supported by the tax-payer like in your institution.
