Developing Custom Applications

In order to keep the original data from observations to allow various experiments in the analysis phase, it was decided to use the original 'rtlsdr.exe' console application in the data acquisition role (saves data in raw IQ data format to a file) and write my own analysis software to process those IQ data files 'off-line' after the observation. The large IQ data files from the longer observation times (up to 1 hour - corresponding to a file size of over 17 GB) required the original 'rtl_sdr.exe' code to be modified to use 64-bit variables.

A data acquisition GUI was written which launches the modified 'rtl_sdr'exe' application to capture data.
