Spectrum Recording

Bay Area Flight

Equipment/Software

• USRP N210 + GNU Radio used to recording spectrum at different frequencies and bandwidths based upon pre-determined schedule
• HDSDR used to review recordings

Code

Scheduled Recording

WARNING: This was hacked up just before the flight. There are many things to be fixed/added (e.g. ability to set receive port when using multiple antennas).

• Create a simple flowgraph in GNU Radio Companion with Parameter blocks to set properties of your capture device
  • Destination should be a File Sink with the destination path set using a Parameter
• Write the schedule

 <Frequency (MHz)> <Name> <Bandwidth (Msps, default: 1)

• Run timed_rx.py passing in your schedule

After returning:

• Run raw capture files through CFileToWAV (with schedule.txt in same directory) to generate Winrad/HDSDR-compatible WAVs
