Signal Identification Guide

Jump to: navigation, search

This wiki is intended to help identify radio signals through example sounds and waterfall images. Most signals are received and recorded using a software defined radio such as the RTL-SDR, HackRF, BladeRF, Funcube Dongle, USRP or others.
Anyone can edit this wiki, so if you see missing or wrong information please feel free to correct it by clicking the 'edit' button at the stop of the signals page. When doing an edit you will be asked to answer a very simple spam prevention question which will appear at the top of the screen after clicking on Save page.
You can also discuss the signals by using the discussion tab at the top of every page, or just by using the comments box at the bottom of this page.
If you would like to contribute an example signal, please contact me at rtlsdrblog__AT__gmail__DOT__com and send a waterfall image, sound or small IQ sample and any information about the signal that you have. Note that it will probably take me 1 - 3 months to get to your signal. If you want to add a signal yourself please consult the instructions here - Adding An Example Signal. Don't worry too much if you mess up the wiki syntax, i'll eventually patrol all the pages and fix them up if something is wrong.
