mystery signals, any idea? quite wideband.

[jdobbs2001]

Two very unusual signals, and quite interesting when looking at them through an SDR since you can see what it looks like and how wide it is. Real curious to find out what they are.

Some type of radar?

Btw, what software is that?

Try using SSB (either USB or LSB, USB is most often used) on these signals instead of AM. In this mode I could be more certain of the source, and could measure rep rates and chirp rates. Both of what you have there appear to be either CODAR, a specialized type of short to medium range costal surveillance radar that plots wave action and ocean currents, or possibly WERA. There are many of these installations around the World, and without a bit more information (such as time of day and your location) it would be difficult to narrow it down as to possible sources.

Other exampels of CODAR here:

(edit) A couple suggestions. Use a screen capture utility instead of an external camera. This will give more detail of the GUI / signal, and make it easier to determine details like signal bandwidth (often such details are required to confirm ID). Label your postings (videos) with the date and time (both in UTC, not your local time), if not in the title than at least include the data someplace in the "about". Use SSB (either USB or LSB, most people use USB) for such signals, this typically will result in better and more usable audio detail.

The 2nd video is definitely CODAR based on the frequency. I'm hearing it right now.

Thanks for the info, BTW what capture util do you recommend? One that can catch the audio as well. for Windows7

I use Screenshot Captor for stills, CamStudio for video/audio.

Most of the videos on my YouTube channel were done on a Windows 7 machine. About half of them were done with the free program CamStudio, the others were done with Snagit. Snagit is not free, but is more versatile than CamStudio.

Both programs will capture audio and video, but you might have some issues setting up Win 7 to allow record of Wave Out, it can be done. I did a thread in the SDR forum describing how to set that up.
