<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Idea: The Digital RF block in GNURadio looks for a very specific directory structure and the properties file must be in the right place. In this case, I have the directory pointer in the GNUradio block set to /tmp . Under the /tmp directory
is the directory /hdf5. Directory hdf5 contains the file drf_properties.h5, plus the folder of the time slice to be displayed, in my case 2019—06-22T17-00-00. Within that directory is the file of the data, in this case
<a href="mailto:rf@1561226332.000.h5" target="_blank">rf@1561226332.000.h5</a> .<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">This structure is peculiar to Digital RF, and it also assumes that you have selected data for a particular center frequency (this is not automatic), and have entered the center frequency into any FFT display you want to use. You might
be able to get it to work for you by replicating this file structure.<u></u><u></u></p>
