How to submit an audio recording

Audio recordings are very helpful to us in the analysis. They have to be in a certain format to be processed by us.

Set SDR receiver to sufficiently large bandwidth.
USB operating mode.
Set the frequency so that the signal is in the middle of the bandwidth, i.e. easily audible.
Record the signal with your computer as audio for at least 1 minute.
Save your recording as a wave file (*.wav).
Go to our upload page and send us your recording.
