Launch the GRC (GNU Radio Companion) application and open the blogger.com file (if you're using the VM provisioned using the steps above, the file will be located in /home/hackrf/). Play the flow graph, then select the channel, radar signature and start the pulse (Pulse > Start). Using GNU Radio Companion: Tutorial 1 GNU Radio Companion (GRC) is a graphical user interface that allows you to build GNU Radio flow graphs. It is an excellent way to learn the basics of GNU Radio. This is the first in a series of tutorials that will introduce you to the use of GRC. 1. GNU cflow analyzes a collection of C source files and prints a graph, charting control flow within the program. GNU cflow is able to produce both direct and inverted flowgraphs for C sources. Optionally a cross-reference listing can be generated. Two output formats are implemented: POSIX and GNU .

If you have GNU Radio 3. Therefore, the examples use UHD sources and sinks, but there is nothing wrong with changing these to e. Download gnu radio flow graph files will, however, need to also update the sample rates throughout the flow graphs according to the device you are using.
You will find that in many of the examples tuning is done using a frequency translating FIR filter rather than changing the USRP frequency. This is because on some daughterboards e. If you are only using a daughterboard that is fast enough you can conveniently change the flow graph to tune the USRP directly and remove the frequency translating filter.
If you are looking for theoretical material for learning digital signal processing and software defined radios see Suggested Reading on the GNU Radio website. This is a simple AM receiver featuring a variable low pass filter and automatic gain control with fixed rate and levels. Recording IQ data in GNU Radio companion is very easy, we simply add a filesink to the flow graph and connect it to the data we want to record. We can use the current date and time to generate a unique filename every time the GNU Radio download gnu radio flow graph files graphs is started.
This prevents previously recorded files to be deleted when we restart the flow graph. Instead of WAV file input you can connect it directly to the output of a WFM receiver like the one presented in the previous section, download gnu radio flow graph files.
Be sure to use the correct sample rates in the band pass filter and the first resampler, download gnu radio flow graph files. The sample rate for the decoder must be 9. Embedded software engineer in the satcom industry during the day. Radio amateur and SDR hacker during the night.

Enter USRP frequency in a text field Tune within the passband using frequency translating filter fast tuning Variable filter width and shape Squelch Supports 5 kHz and 2. AM Receiver This is a simple AM receiver featuring a variable low pass filter and automatic gain control with fixed rate and levels. Recording IQ data using dynamic file names Recording IQ data in GNU Radio companion is very easy, we simply add a filesink to the flow graph and connect it to the data we want to record.
Sorry there is no GRC file, but it should be very easy to reproduce from the screenshot. Author: Alexandru Csete Embedded software engineer in the satcom industry during the day.
