Radio Telescope simulations
===========================

These are written in GNU Radio (http://gnuradio.org/), which is the
software we use at the observatory to run the radio telescopes. GNU
Radio can be installed using the links for your favourite operating
system, at

https://wiki.gnuradio.org/index.php/InstallingGR

with a Windows 10 installer at

http://www.gcndevelopment.com/gnuradio/downloads/installers/v1.7.0/gnuradio_3.8.1.0_win64.msi

Once installed either click on the "GNUradio companion" icon (if
there is one) or (in windows) type "gnuradio companion" in the start window.
You can then open the file radio_telescope_simulator.grc copied
from this directory.

This should bring up a flow-diagram-like description of the
simulator. To run it, click on the play triangle in the top bar,
labeled "exicute the flow graph" if you hover over it.

To get the exact appearance we use in the lectures go to 
"Tools|Set Default QT GUI Theme" and choose the gnuradio.qss theme 
supplied in this folder.
