I need to find the source of some radio interference. So I've ordered an RTL-SDR kit and now I need to find some suitable software. I don't know much about radio - I could just about explain the difference between AM and FM :(
So if anybody can suggest places to look for info or specific packages that are good for locating interference and also easy to use for a noob, I'd be very grateful.
Cheers, Dave
I don't have any experience with that sort of software, but generally speaking, you just use a receiver with a directional antenna to find a noise source. What is being interfered with? Any equipment used will have to be able to receive the noise frequency. Also, some interference comes in through the power cord, etc., so you have to understand possible sources. It's a huge spectrum, so you'll need some clues to narrow things down. All my desktop computers play havoc on AM reception. Specially LW.
LAN over the mains power cable is terrible.
Ever stop to think that your power lines are acting like a longwave antenna, transmitting and receiving. Need some filters. Neighbors probably notice it also.
I assume the PSU has an EMI filter. But my receiver is specially sensitive, and it is close to the main computer. I must remember to try when it is off.
There was an attempt some years ago to sell internet service over the power lines. A few test areas were tried. Didn't work well. Way to much interference.
I know... but there is Ethernet over the mains inside the house. I don't remember the proper name... Powerline networking? There is another name.
A stupid idea, should be forbidden. Ask any HAM.
