Adding a Signal Entry

If you have difficulties adding your samples to the website, please send the material to sigidwiki_AT_gmail_DOT_com. Please be aware that if your signal is a VHFVery High Frequency (30-300 MHz)-UHFUltra High Frequency (300-3000 MHz)+ signal, you should provide an IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. of the signal with your materials, since it is very very difficult to recreate an FMFrequency Modulation-modulated or wide-band signal from partial or demodulated audio.

To add a new signal you'll first need to make a free sigidwiki.com account. You can do this by clicking the create account button in the top right. You cannot upload files without an account.

To add a signal to the wiki please use the Add Signal Form.

Note that the audio file must be in MP3 or OGG format. We cannot accept files in the WAV format. Please try to upload a sample that is about 10 - 30 seconds long, unless a longer sample is needed. Any longer and it just wastes bandwidth. Please try to select the correct demodulation mode when recording a signal. For submitting HFHigh Frequency (3-30 MHz) signals, usually audio should be in USBUpper Side Band Modulation (Radio, referring to reception and modulation mode)Universal Serial Bus (Computer, referring to USB Ports and cables) or AMAmplitude Modulation mode. For VHFVery High Frequency (30-300 MHz) and UHFUltra High Frequency (300-3000 MHz) frequencies audio should be in the NFMNarrowband Frequency Modulation mode or sometimes in AMAmplitude Modulation format. The RAW audio mode is usually not very useful.

Any IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. files you want to upload must be zipped and less than 8mb. See below for information on how to get a smaller IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file size. If you would like to add a large IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file, please upload it to a file host such as http://www.mega.co.nz, then link to it in the wiki page in the long description text box.

In the add signal form the information that will be displayed on the front page is the information that is input into the main form fields. If you have extra information about the signal, please use the Long Description text box. If you want to add extra images or audio files to the long description box please use the Upload file option on the left sidebar which is under the tools heading. Remember the file names you've used.

Use the code <html5media width="300">File:EXTRA_MP3_FILE.mp3</html5media> to add MP3 or OGG files to the long description and the code [[Image:EXTRA_IMAGE.JPG|150px]] to add extra images.

After adding the signal page it will automatically appear on the main page, but some data properties may take up to 24 hours to update.

Adding an Unidentified Signal

To add an unidentified signal please use the Add Unidentified Signal Form. The procedure is the same as adding a known example signal discussed above, with a few requirements to aid in identifying such signals:

You should supply an IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file of the signal and either upload it on our wiki in a zip (Maximum file size 8MB) or link it from a file hosting service. To analyze a signal and to correct possible incorrect audio demodulations, we must have the raw IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. radio frequency recording of the signal.

If possible, provide an analysis using tools such as Signals Analyzer. A tutorial on how to analyze signals with Signals Analyzer can be found here.

If your country provides it, look up the frequency of your signal in your country's telecommunications bureau. For the United States, this agency is the FCC. A list of telecommunications agencies can be found here.

Editing a Signal Page

Anyone can edit a signal page by clicking the "edit with form" at the top of the page. Please use the form unless you are experienced with wiki editing. If you are a guest user, you will need to answer a simple anti-spam question after pressing submit. Note that the main page can take up to 24 hours to refresh. Also, due to browser caching, after editing the page you may need to do a hard refresh. On most browsers you can do a hard refresh by pressing CTRL + F5.

Adding an IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. Example File

We now allow you to upload small (less than 8mb) IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file examples. To get an IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file with such a small file size we recommend using the decimation drivers in SDR#. These are available here. Set the decimation to something that adequately zooms in on the signal, for example for a narrowband signal you might set the decimation to 16 or 32. Next record a 8-bit PCM baseband IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. file for a few seconds with the decimation set. Watch the file size and stop it if it grows too large. Next zip the file up as this will often reduce an IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. files size by over 5x. Then upload the zip file to the wiki using the form.
