The IARU MS is often asked for audio samples that can be used to help identify unknown intruder signals heard in the Amateur bands.
Below are links to audio samples in WAV format of various analog and digital radio signals which might be encountered in the Amateur Radio bands. Listening to these samples and comparing them with the sound of an unidentified signal on the air, you can often identify the unknown signal, although there is no guarantee that you will find an exact match in these collections. Due to the complexity of some new signals, however, even an "exact match" can be misleading, but the examples provided will at least help you to tell the differences between certain similar signals and may provide the key you need to identify an unfamiliar signal.
