There are also two paperback books: Technical Handbook for Radio Monitoring VHF/UHF ( PDF Excerpt) & Technical Handbook for Radio Monitoring HF ( PDF Excerpt) which have a very comprehensive list, description and images of many signals. A very nice overview video of the HF spectrum by balint can be found here. More sites with sample audio can be found at this list on. (Note I am currently backlogged with contributed signals, if I haven’t replied or added your signal yet it will be done within a month or two). If you would like to suggest a modification or contribute a sample, please send a sample, waterfall image and information about the signal to, or post in the comments. If you enable stereo mix and pass the sample audio to an appropriate decoding program the sample audio should be decodable for most samples. I will be slowly adding more to this list over time.

Most of these have been received with an RTL-SDR software defined radio. Anyone can edit and improve the information on the pages on the wiki.Ī guide to help you identify some amateur and utility digital radio signals and sounds which you may find on the frequency spectrum. Please use the new Signal Identification Wiki which has many new signals. NOTE: Recent changes to WordPress seem to have broken the audio on this page.
