I attached the code with the hope that someone would like to improve it … maybe 

put it on sourceforge or github. I will not have time to do anything about it for a few 

weeks. 

Works at least with linux … haven’t tried OSX or win. 

Needs: numpy, scipy, matplotlib, npyscreen (https://pypi.python.org/pypi/npyscreen/), 

pyrtlsdr (https://github.com/roger-/pyrtlsdr/releases [use the old release, new code python 3 only])

start with: 

python peekSDR.py -d (in one window to start database)

[can be run on different computers as long as you have the same filesystem and stand in the same directory]

in the user interface “f” plots ffts of recorded signals. “1” starts gqrx with the recorded signal.
