You can set the range by middle clicking (with the mouse wheel) and
setting the Int. min parameter. Try -120 to start with.

Hello,
We are running gnuradio v 3.7.8 on Ubuntu 15.08. H/W is B210. We are
looking at our self echo from EME (moon bounce).
When running uhd_fft, we see clear EME echo signals on the FFT display (10-20 db above
the noise). However, we don't see these signals on the waterfall display. We do see
the very large signals when we transmit. Is there a way to adjust the
"vertical" range of the display so that the noise is mapped onto something
black or nearly so and signals 20 db above the noise appear as bright colors?
Sincerely,
Dan Marlow
