This page will guide you to record the signal.

We provide SpriteRecorder_RTL.grc to record the signal. Launch GNU radio Companion and open SpriteRecorder_RTL.grc, also remember to modify the output file path in File Sink blocks, and run it. The recording starts after the window pops out, and ends whenever you close the window or stop the flow graph.

We are using RTL-SDR, it's frequency is 1MHz. If you are using other devices, you may have to change the source block and decimation to set correct sampling frequency. Current decimation is 5, which makes the sampling frequency 200kHz. Aviliable frequencies are

f1

You may use any other approach to record the signal as long as the format is complex 64.
