That's really cool. I could use something like that for a machine
with a USRP2 that I sometimes control remotely. How did you get the
FFT to display in ASCII text via an SSH terminal? Was it a
modification of "usrp2_fft.py"? Or is it something you wrote custom
for yourself?
I made a little c++ header with 2 functions:
- a log-power-dft (in case you dont want to link fftw)
- a function to turn dft bins into a printable string

There is an example in uhd that uses this to make a live dft plotter.
The app also uses a little bit of curses for clearing the screen and
getting the terminal dimensions.
See host/examples/rx_ascii_art_dft.cpp
